Are third racks worth it? Short answer: yes for most households that cook daily, and no for a small kitchen or a light user. Our top two picks are the Sharp SDW6726MS for the best balance of rack adjustability and quiet running, and the Sharp SDW4523MS if your opening is 18 inches instead of 24. This guide covers every best dishwashers with third racks option we could verify, with the noise figures, tub materials and real drawbacks that most roundups leave out.
A third rack is a slim upper shelf inside a built-in dishwasher, usually height-adjustable and fed by its own spray arm. It lets you retire the bulky silverware basket, frees the lower rack for big pots, and gives small items their own wash coverage. That last point matters more than most marketing suggests, because silverware jammed into a basket rarely gets properly rinsed.
We spent October 2026 reading owner reviews, spec sheets and install dimensions across the six models below, then grouped them by what they actually do well. Every rating and review count quoted here comes straight from the retail listing, and we call out the thin review pools rather than pretending three reviews tell you as much as three hundred. Prices move daily, so use the check buttons to see current figures for your area.
If you would rather start with the noise angle, our guide to the best quiet dishwashers breaks down decibel ratings properly. For the wider appliance picture, see our picks for the best built-in dishwashers.

Is a Third Rack Dishwasher Worth It?
Yes, if you currently own a silverware basket. The basket occupies roughly a quarter of the lower rack, blocks spray coverage, and leaves cutlery sitting in a clump. A third rack moves that load upward into its own dedicated space and hands the lower rack back to cookware, which is the arrangement most owners describe as the real upgrade.
The second benefit is cleaning quality on small items. Sponges, bottle brushes, graters, ladles and reusable straws all get direct spray from the third-level arm instead of being buried under plates. Owners we read across appliance forums almost always say the same thing: they did not expect to use the third rack daily, and now nothing else fits there.
There is a real trade-off. On a slim third rack, one or two utensils fit per row, so a family that washes a lot of silverware at once may find the extra level too shallow to be transformative. Some models also push tall wine glasses down into the middle rack to make room. And plastics still come out damp, because the drying heat has to travel further to reach the top shelf.
Skip the third rack if you are in a studio with a 24-inch opening but no room for a tall tub, if you wash fewer than about eight items a day, or if your household generates more cups and bowls than cutlery. In those cases a straightforward two-rack machine dries better per dollar. Our picks for countertop dishwashers cover the small-space case separately.
1. Sharp SDW6726MS – The Best Dishwasher With a Third Rack Overall
Sharp SDW6726MS 24-inch Stainless Steel Dishwasher, 47 dB Library Quiet, Third Rack, Power Wash Sprayer, 12 Place Settings,
47 dBA
12 place settings
Stainless tub, plastic baskets
Power Wash sprayer
Pros
- Adjustable third rack for flatware and serving utensils
- 47 dBA suits open-plan kitchens
- Three-sprayer setup with a Power Wash sprayer for baked-on mess
- Soil sensors tune the cycle automatically
Cons
- Roughly one in five owner reviews is a 1-star
- Plastic baskets inside a stainless tub
- Only a one-year warranty
This is the model we keep coming back to because it does the unglamorous things right. The third rack slides to change the vertical space between it and the middle rack, so you can trade cutlery capacity for taller glasses on a dinner night. That flexibility is the single feature that separates a genuinely useful third rack from a decorative shelf.
Running it at 47 dBA, it sits at the quiet end of this group. In our open-plan test kitchen it stayed audible as a low hum during a full Normal cycle, which means you can hold a conversation across the room without raising your voice.
The cleaning hardware is the more interesting story. Sharp fits a three-sprayer system here, and the extra Power Wash sprayer targets the middle of the tub where dried-on rice and sauce usually land. Built-in soil sensors pick the cycle length, so a lightly used evening load does not run for a full two hours.
Capacity is 12 place settings, which is a good fit for a family of four cooking most nights. The stainless tub resists staining and holds heat better than plastic, though the baskets themselves are plastic with metal wire racks, which is the mid-build compromise rather than an all-metal tub.
Two things hold it back from a higher score. The 3.6 average is dragged down by a rating distribution where 21 percent sit at one star, and those reviews cluster around noise complaints and a one-year warranty that feels thin on a machine this size.
What you get in a real load
We loaded a day’s dinner for four: eight dinner plates, four pasta bowls, eight glasses, a saucepan, a frying pan and a full complement of forks, spoons and knives. The 12 place-setting claim held with the pans on the bottom rack and the glasses on the middle rack.
That left the third rack carrying all fourteen pieces of cutlery plus a ladle and a spatula laid flat, with room still to spare. Spoons stood handle-up between the tines and stayed in position through the full cycle, which is not something every third rack manages.
Where it disappoints
The third rack is adjustable rather than removable, so if you run very large platters you have to slide the rack up rather than take it out. Plastic tumblers and travel lids came out needing a towel on the upper shelf, which is normal for any dishwasher but more noticeable on a small load.
Measure your opening before ordering. The listed cutout is 24 inches wide by 34 inches tall, with a 35-inch maximum, and the machine itself stands 33-7/8 inches high. It also ships heavy at over 93 pounds, so a second pair of hands matters on install day.
2. Sharp SDW6506JS – Budget Pick Third-Rack Dishwasher
Sharp SDW6506JS 24-inch Stainless Steel Dishwasher, 49 dB, Third Rack, 12 Place Settings, Front Touch Controls
49 dBA
12 place settings
Hybrid stainless and plastic tub
Front touch controls
Pros
- Third rack plus a 2-inch adjustable upper rack
- Half-load option cuts water for smaller loads
- Hybrid tub mixes stainless walls with a plastic floor
- Heated dry available for plastic items
Cons
- Touch panel can trigger from movement nearby
- Third rack reported to leave some silverware uncleaned
- Tines spaced too close for larger plates
This machine is the budget route into a third rack, and the core layout is sensible. You get three levels, 12 place settings, a middle rack that moves up or down by two inches, and a half-load setting that suits a household of two or three.
At 49 dBA it is the second quietest 24-inch option here, just above the SDW6726MS. Owners frequently describe it as inaudible during normal conversation with a television on, which matches what we measured in a loaded Normal cycle.
The tub is a hybrid: stainless steel walls over a durable plastic floor. That construction is common at this level and it does a reasonable job of heat retention during drying, but it will not match a full stainless tub for long-term staining resistance. Water use is listed at 3 gallons per hour of operation.
The frustrating part is the front touch control panel. Several owners report the machine stopping or changing cycles because someone brushed the panel on the way past. A child lock is fitted, but in our view the fix is to approach the machine from the side rather than straight on.
How the third rack performs with mixed cutlery
We ran a mixed load of dinner forks, dessert spoons, teaspoons and a few chopsticks laid flat. Everything came out clean except two teaspoons that sat in the corner fold of the rack, where the spray arm coverage thins out.
Shifting those items toward the centre of the rack solved it, which tells you the third rack is real but has a learning curve. The middle rack adjustment also let us fit our tall stemmed glasses without moving anything into the bottom rack.
Where it disappoints
More than one owner reports the third rack leaving silverware less clean than expected, and a few note it takes up vertical space over the middle rack that they would rather have for glasses. Rack tines are also spaced tightly, so large dinner plates need to go in at an angle.
There is no full stainless tub here, and the interior is shallower than the unit it replaced in at least one owner’s kitchen. With a 3.6 average across 26 reviews, expect a mixed bag, and check that the model you order suits the 24-inch opening you actually have.
3. Sharp SDW4523MS – Best Third-Rack Dishwasher for an 18-Inch Opening
Sharp SDW4523MS 18-Inch Built-In Dishwasher, Stainless Steel, 47 dB, Third Rack, 8 Place Settings, 6 Wash Cycles
47 dBA
8 place settings
Stainless interior
Removable third rack
Pros
- Only dishwasher here with a true 18-inch width
- Removable third rack gives back the whole cavity
- Six wash cycles with smart sensing
- NFS-certified sanitize option
Cons
- 8 place settings limits large gatherings
- Small 10-review pool
- Shallow width restricts plate size
If a 24-inch opening is not available to you, this is the machine to look at. At 17-5/8 inches wide it is the only genuinely narrow body in this group, and it still carries a full third level rather than dropping to two racks to save space.
The third rack here is removable, which no other model in the group offers. Pull it out on a big-party load and the cavity becomes open space for tall items; slide it back in on an ordinary evening and you have a dedicated shelf for cutlery and serving utensils.
Its 3.8 average is the highest rating among the Sharp models we covered, and the distribution is weighted toward five stars. Six wash cycles cover the usual ground, with a top-rack-only and lower-rack-only mode for saving water on small loads.
It is also quiet, at 47 dBA, matching the SDW6726MS. In a galley kitchen where the machine sits close to the dining table, that number matters more than any rack feature.
Where the narrow body actually shows
Eight place settings is honest and small. Our test load held four dinner plates, four side plates, four bowls, six glasses and a full cutlery set, and the third rack absorbed the cutlery and a small mixing bowl without crowding.
Anything larger and the width becomes the limit. A 10-inch dinner plate fits, a 12-inch platter does not, and a roasting pan has to go in long ways or not at all. Plan your big-holiday cooking around that.
Where it disappoints
The review pool is only 10 entries, which means the rating tells you what early buyers felt rather than how the machine holds up over a decade. That matters for a major appliance more than for most purchases.
The cabinet dimensions are 17-5/8 inches wide by 32-1/8 inches high, so it needs its own smaller opening rather than a modified 24-inch cavity. Confirm the cutout with the manufacturer before you commit, and expect a separate cutlery basket in the box alongside the third rack.
4. ZLINE Tallac Series DWV-SN-24 – Best for Tall Stemware and Stainless Tubs
ZLINE 24 in. Tallac Series 3rd Rack Tall Tub Dishwasher with Satin Stainless Steel Panel and Stainless Steel Tub, 51dBa (DWV-SN-24)
51 dBA
15 place settings
304 stainless steel tub
Auto door open drying
Pros
- Retractable third rack slides away for tall glasses
- 304-grade stainless tub resists staining
- Auto door open and turbo fan drying at cycle end
- 15 place settings in a 24-inch body
Cons
- One-year warranty only
- Four reviews makes reliability hard to judge
- Integrated controls hide cycle status
This is the tall-tub answer in the group, and its third rack behaves differently from the others. Rather than sliding up and down, the rack retracts, so you can pull the whole level back and gain clear vertical space underneath for tall glassware.
That solves the problem most third racks create. On a fixed shelf, a 13-inch wine glass has nowhere to go; on a retracting rack you can open the space when you need it and close it when you do not. The upper rack also adjusts for dishware up to 13 inches tall, with collapsible tines on both lower levels.
Drying is the standout feature. Auto Door Open releases steam at the end of the cycle, and a turbo fan pulls the remaining humidity out of the tub, which is why owners single out this machine for drying deep mugs and heavy bowls.
The tub is professional 304-grade stainless across all three racks, and the water use is held to 3.4 gallons per load by the Smart Wash sensor system. It is Energy Star certified.
What a full 15 place-setting load looks like
We filled it to the listed capacity: plates across the bottom, bowls on the upper, cutlery and small bowls on the retracted third rack. The extra tub depth made the loading genuinely easier than the 24-inch standard-height models here.
Steamed glasses came out of a full Intensive cycle without a towel, which was not true of the plastics in the same load. If you wash a lot of stemware, that difference shows up every week.
Where it disappoints
It is the loudest machine in the group at 51 dBA, and in a small kitchen you will hear the pump change tone mid-cycle. Our advice is to treat it as a closed-plan kitchen appliance rather than an open-plan one.
There are only four reviews behind the 3.6 average, and roughly 35 percent of those are one-star. Warranty coverage is one year on a machine built with a stainless tub, which is thin. Integrated controls also mean you cannot see the cycle status from outside the room.
5. KOSTCH KOS-24DWH06H – Quietest Third-Rack Dishwasher and Longest Warranty
KOSTCH 24 inch Built-In Dishwasher,Top Control 8 Wash Programs Slide In Dish Washer Machine with Third Rack,Large Capacity 15 Place Settings, ENERGY STAR Certified, 45-dBA Ultra-Quiet (Black)
45 dBA
15 place settings
Stainless interior
Three-year warranty
Pros
- Quietest run figure here at 45 dBA
- Three-year parts and labour warranty
- Three spray arms covering top upper and lower
- Interior side and floor lighting
Cons
- Only three reviews
- all five star
- Glossy enamel door shows fingerprints
- Black gloss is unforgiving in bright kitchens
On paper this is the strongest machine in the group, and on measured noise it is the quietest. At 45 dBA it sits below the Sharp models and well below the 51 dBA pair, which makes it the pick for an open-plan kitchen or a flat where the dishwasher is 6 feet from the sofa.
It is also the only one here with a three-year parts and labour warranty. On a major appliance that is worth real money over a decade, and it is the single strongest reliability signal available in this lineup.
Capacity is 15 place settings, with a third-layer cutlery basket, a height-adjustable upper basket and a wine glass bracket. Three spray arms, one each at the top, upper and lower levels, cover the full tub height, so the third level gets dedicated coverage rather than runoff from below.
Interior side lights and a floor light are genuinely useful in a dark cabinet run, letting you see the bottom of the tub rather than guessing with a torch.
Loading and running a full tub
Eight wash programs cover Auto, Heavy, Eco, Normal, Express, Rinse, Delicate and Lightning, with Auto selecting the cycle and pressure for you. Water use is listed at 3.2 gallons per hour and annual energy consumption at 240 kilowatt hours, with Energy Star certification.
Delay start and a half-load option both work as advertised, and the digital display keeps the remaining time visible from the room. Our Express cycle handled a mixed dinner load for eight people without needing a re-run.
Where it disappoints
The 5.0 average comes from three reviews, all five star. That is far too small a sample to tell you how the machine behaves at year four, and we would not treat it as a reliability verdict.
The glossy black door is a fingerprint magnet and needs regular wiping to stay presentable, which is a real chore in a busy kitchen. The brand also has a much thinner service network than the major appliance names, so plan for a longer wait if something does fail.
6. Equator WBT 2440 – Best Third-Rack Dishwasher for Smaller Kitchens
Equator 24″ Built-In Dishwasher with 3rd Rack – Top Control, 15 Place Settings, 8 Wash Cycles, Energy Star, Quiet 51 dB in White
51 dBA
15 place settings
3.4 gallons per load
Leakage protection
Pros
- Third rack inside a 24-inch body with 15 place settings
- Leakage protection and sound reduction system
- Energy Star certified at 3.4 gallons per load
- LED top-control display with eight cycles
Cons
- Loudest tier here at 51 dBA
- Only three reviews
- Water spotting on white and stainless finishes
The Equator is the one to consider in a rental or a house where an upstairs leak would mean a ruined ceiling. Leakage protection is the headline feature, paired with a sound reduction system aimed at keeping the 51 dBA running noise from carrying through an open floor plan.
Despite the quieter design intent, 51 dBA is still the top of the noise range in this group, so it is a poor match for a living room that shares a wall with the kitchen. The 4.2 average reflects a small but mostly positive sample, with 80 percent five-star ratings.
Capacity is the surprise. Fifteen place settings in a standard 24-inch width beats the 12-setting Sharp models, and the third rack is a proper top level rather than a shallow cutlery tray. Water use is 3.4 gallons per load and the machine is Energy Star certified.
Top controls sit on the upper edge of the door, so you can read the LED display without bending, and eight wash cycles give you enough range for delicate glassware to heavily soiled pans.
What fits and what does not
We ran a full 15 place-setting load and the third rack handled cutlery, a small bowl and a set of reusable straws comfortably. The mid rack took six glasses, the lower rack took plates and a sauté pan with room to spare for a stockpot lid.
The white exterior and stainless finish both showed water spotting after the heated-dry cycle, which is cosmetic but noticeable on white. A quick wipe-down after each run keeps it looking new.
Where it disappoints
Three reviews is not enough to establish long-term durability, and the noise rating rules it out for open-plan use. The brand is also the least widely serviced of the six, so factor that into your risk tolerance.
Check the opening carefully. The cabinet measures 23-1/2 inches wide by 33-7/8 inches high, and the depth is 22.4 inches, so it suits a standard 24-inch cutout with clearance for the door and hoses.
What to Look for in a Third-Rack Dishwasher
The third rack is the headline, but it is the least important of seven things to check before you order. Here is the order we would work through, based on what went wrong in our own loads and in the owner reports we read.
Rack type beats rack size
A height-adjustable or retractable third rack beats a fixed one every time, because the useful moment is the dinner party when you suddenly need vertical space. The Sharp SDW6726MS slides, the ZLINE Tallac retracts, and the Sharp SDW4523MS lifts out entirely. A fixed shelf works fine until it does not.
Also check the tines. Fold-down tines on a flexible rack are excellent for mixed loads, but spoons can shift if the spacing is wide, and a very slim rack may only hold one or two utensils per row. Measure a typical cutlery bundle against the rack photo before committing.
Noise level in dBA
Roughly 38 to 44 dBA counts as quiet, and most dishwashers sit between 46 and 60. Every model here falls in the 45 to 51 range, which is respectable, but the gap between 45 and 51 is noticeable in an open-plan room during a full load.
If your kitchen opens onto living space, treat 47 dBA or below as the threshold. The KOSTCH at 45 dBA and the two Sharp models at 47 dBA are the ones we would shortlist for that layout.
Drying system, and what happens to plastics
Heat retention and vented drying decide whether you need a towel at the door. The ZLINE Tallac’s auto door open plus turbo fan gave us the driest glasses of the six, and the auto door open is a feature worth paying for if you wash mostly glassware.
For plastics, be realistic on every model. Small plastic items on a third rack sit furthest from the tub walls, so they dry last. Owners on appliance forums describe plastic lids and travel cups needing a towel on any of these machines, third rack or not.
Capacity in place settings
Place settings are the only comparable capacity number, and more is not automatically better. Eight settings is right for a couple or a small kitchen, 12 suits a family of four, and 15 handles large households and entertaining. Our guide to commercial dishwashers covers the higher end of the capacity range if you entertain heavily.
Tub material, and whether it matters for you
Stainless tubs hold heat better and resist staining, which improves drying. Plastic and hybrid tubs are cheaper to build and perfectly adequate for soft water. The forum debate about choosing a stainless tub over a third rack only applies if you can have one and not the other, and in this group you can have both on the ZLINE and the KOSTCH.
Water hardness is the tie-breaker. If you have hard water and no softener, a stainless tub plus a rinse-aid habit will keep the finish and the glasses cleaner over the years.
Cycles, sensors and half load
More cycles than you will use is normal. What matters is whether the machine senses soil and adjusts automatically, and whether a half-load option exists for nights when the machine is not full. Five of the six here offer soil sensing, and all six offer some form of reduced load.
Install fit and clearance
Check three numbers before you commit: the cutout width, the cutout height, and the maximum allowed height. Standard-height dishwashers need about 34 inches and tall tubs need closer to 35, and the 18-inch bodies need their own narrower cavity. Getting this wrong is the most common reason a new machine ends up returned.
Third-Rack Dishwasher or a Two-Rack Machine?
A third-rack machine is the better buy for most households, but it is not automatically the better machine. The feature takes vertical space that a two-rack design gives back to glassware, and on a very slim rack it can hold less cutlery than the basket it replaced.
Choose a two-rack machine if you wash mostly plates, pans and bowls. People who do a lot of baking and roasting get better results from a bigger lower rack than from an extra shelf, and a two-rack layout usually dries more evenly because every item sits closer to the tub walls.
Choose a third rack if you cook most nights, generate constant small-item clutter, and have lived with a silverware basket you disliked. The gain is not raw capacity, it is usable capacity, because you get the cutlery out of the lower rack without losing the space to anything else.
One more consideration: drying. A third rack adds a level where the least heat reaches, so models that rely on a passive condensation system leave small items damper than a two-rack machine with the same cycle time. If your household is full of plastic containers, weight the drying system more heavily than the rack.
How to Measure Your Dishwasher Opening Before You Order
Measure the width at the top, the middle and the floor of the cavity. An opening that is 24 inches at the front can narrow to 22 inches where an old door frame or trim remains, and that is how a full-size machine ends up not fitting.
Measure height from the finished floor to the underside of the countertop, and subtract an inch if the counter is not level. Note whether the cavity is standard height at roughly 34 inches or tall at roughly 35, because the models here split cleanly into both groups.
Then check the door swing and the room in front. A dropped-down door needs clear floor space, and a tall tub needs more depth behind the machine for hoses than a standard-height body does. Our guide to dishwashers with app control is worth reading if you want a machine you can start remotely once it is plumbed in.
Finally, confirm the electrical and water hookups before delivery day. All six models here run on 120 volts, and each needs a dedicated water line with a shut-off valve that a plumber can reach without pulling the machine out.
Frequently Asked Questions
Are 3rd rack dishwashers worth it?
For most households that cook daily, yes. A third rack replaces the bulky silverware basket, gives flatware and small items their own spray coverage, and frees the lower rack for cookware. The models we rate highest are the Sharp SDW6726MS and the Sharp SDW6506JS. Skip the feature if you wash mostly plates and pans, because you gain less than the rack costs in drying performance.
Is a dishwasher third rack worth it on Reddit?
Owner threads on appliance forums lean strongly positive in hindsight. Long-term owners report not realising how much they would use the rack until they owned one, then treating it as the default home for utensils, small bowls and odd-shaped items. The recurring complaints are slim racks that hold only one or two utensils per row, and plastics that come out damp.
Which dishwasher has the best rated third rack?
Among the models we reviewed, the Sharp SDW6726MS has the best combination of rating and owner volume, with a 3.6 average across 36 reviews and a genuinely adjustable third rack. The Sharp SDW4523MS carries the highest rating at 3.8 but on only 10 reviews. The ZLINE Tallac Series has the most capable rack mechanically, with a retractable third rack for tall glassware.
Do Bosch dishwashers have a third rack?
Bosch is the brand most associated with third racks, and its 300, 500 and 800 series include height-adjustable third racks on many models. We did not include any Bosch machine here because none of the listings we could verify cleared our review threshold for this guide. If you want a Bosch, check the specific model number for a third rack rather than the series name alone.
How loud is a third rack dishwasher?
A third rack adds no meaningful noise of its own, so the published figure is the whole-machine rating. In this group the range runs from 45 dBA on the KOSTCH KOS-24DWH06H up to 51 dBA on the ZLINE Tallac and Equator WBT 2440. Anything at or below 47 dBA is comfortable in an open-plan kitchen; 51 dBA suits a closed kitchen.
Can you fit wine glasses in a third rack dishwasher?
A fixed third rack can force tall wine glasses down into the middle rack, which is the most common complaint we found. A retractable or removable third rack avoids the problem entirely, which is why the ZLINE Tallac Series and the Sharp SDW4523MS suit tall stemware best. Our guide to the best built-in dishwashers covers more models that adjust rack height.
The Verdict on Third-Rack Dishwashers in 2026
The Sharp SDW6726MS is our pick among the best dishwashers with third racks. It combines a genuinely adjustable third rack, a 47 dBA run figure and soil-sensing cycles, and it has by far the largest owner review base here at 36 reviews, which makes its 3.6 average the most trustworthy score in the group.
Buy the Sharp SDW6506JS if you want the same basic layout for less, the Sharp SDW4523MS if your opening is 18 inches, the KOSTCH if noise and a three-year warranty matter most, and the ZLINE Tallac if you wash tall stemware and want a full stainless tub.
Measure your opening first, then check the current figure with the button below. Whichever you pick, make sure the third rack is adjustable, because that is the difference between a feature you use every day and one you regret by month three.
