Kitchen Sinks
The best 33 inch kitchen sinks
33 x 22 inches is the most common kitchen sink size in America. The thing nobody tells you is which cabinet it needs, and the answer is not 33.
Disclosure: we earn a commission if you buy through the Amazon links on this page, at no extra cost to you. Commission never decides a verdict or a ranking position — read our editorial policy and affiliate disclosure.
How we assessed these: we compared published manufacturer specifications for the named model numbers, read from each maker's own product page or specification sheet and linked at every figure. We have not tested these sinks and we do not own them. No independent laboratory publishes chip, stain or scratch testing for residential kitchen sinks, so material claims here are the manufacturer's and are labeled as such.
Short answer
The Kraus KHT300-33 is the 33-inch sink to buy for most kitchens: 33 x 22 x 10-5/8 inches overall with a 31 x 18 x 10 inch bowl, TRU16 gauge T304 stainless, dual mount so it drops in or undermounts, and a bottom grid and drain assembly in the box. Before you order any of them, note the catch: every 33-inch sink on this page states a 36-inch minimum cabinet. A 33-inch sink does not fit a 33-inch cabinet.
33 x 22 inches is the default American kitchen sink. It is the size that goes under a 36-inch base cabinet, the size most replacement cutouts already are, and the size with the widest choice of models at every price. If you are replacing a sink and want the fewest surprises, this is the size to stay in.

The cabinet question, answered first
Google's own suggestions for "33 inch kitchen sink" include "will a 33 inch sink fit in a 33 inch cabinet", which tells you how often this goes wrong. The answer is no. A 33-inch-wide sink needs the cabinet to be wider than the sink, because the cabinet has side walls and the countertop needs a margin of support on each side of the cutout.
Kraus publishes a 36-inch minimum cabinet for the KHT300-33, the KHT302-33, the KWT310-33/5.5 and the Premier KTM100-33. Blanco publishes 36 inches for the Diamond Silgranit at 33-1/2 inches wide. That is five sinks spanning 18 gauge to TRU16 and stainless to composite all saying the same thing, and it is the single most useful figure on this page. Kitchen sink sizes and cabinet fit has the full arithmetic including the front-to-back dimension.
What varies between them, since the outside dimension does not
All five are around 33 inches wide. What separates them is bowl depth, bowl layout, gauge or material, how they mount, and what is in the box — and those differences are much larger than the size they share.
| Model | Overall size | Bowl | Gauge / material | Min. cabinet | In the box |
|---|---|---|---|---|---|
| Kraus KHT300-33 | 33" x 22" x 10-5/8" | 31" x 18" x 10" deep | TRU16 gauge T304 stainless | 36" | Bottom grid, drain with strainer, decorative drain cover |
| Kraus Premier KTM100-33 | 33" x 22" x 8" | 27-4/5" x 16" x 7-1/2" deep | 18 gauge T-304 stainless | 36" | Drain with strainer, hardware, cut-out template; no grid |
| Kraus KHT302-33 | 33" x 22" x 10-5/8" | Two bowls, 15-1/2" x 18" x 10" deep | TRU16 gauge stainless | 36" | Two grids, two drains, cut-out template, hardware |
| Blanco Diamond Silgranit | 33-1/2" x 18-1/2" | 9-1/2" deep | Silgranit, up to 80% ground granite | 36" | Not published on the listing we read |
| Kraus KWT310-33/5.5 | 33" x 22" x 6" | 31" x 16" x 5.5" deep | TRU16 gauge stainless | 36" | Grid, bamboo board, drying rack, drain, template |
Every figure comes from the maker's own product page or specification sheet for that exact model number, listed in the sources below. Cells reading "not published" mean we did not find the figure stated. Note the 15-inch spread in overall height between the shallowest and deepest sink here - that, not the width, is the decision.
Depth is the real choice at this width
A 10-inch bowl holds a roasting pan flat, absorbs the splash from a high-arc faucet and hides a stack of dishes from the room. A 7-1/2 inch bowl is easier on your back, takes less reaching into, and clears a low trap arm. A 5.5-inch ADA bowl exists so a wheelchair user's knees fit under the counter.
There is no universally right answer, which is why the five sinks here span 5.5 to 10 inches of bowl depth at the same 33-inch width. How deep should a kitchen sink be works through the ergonomics, the trap-arm constraint and what a garbage disposal does to the numbers.

1. Best overall
Kraus KHT300-33 drop-in sink
Kraus · Best for replacing a sink without touching the counter
The drop-in we would fit in most kitchens, because it is a 16-gauge sink sold as a dual-mount: the rim is finished to sit on the counter, and the same sink can be undermounted later if you ever replace the countertop. At 10 inches deep with a rear-set drain it behaves like a modern undermount while asking nothing of your existing counter.

- Certification
- cUPC to ASME A112.19.3 / CSA B45.4 source
- Included
- Bottom grid, drain assembly with removable strainer, decorative drain cover source
- Warranty
- Kraus limited lifetime source
What works
- 16-gauge steel in a drop-in, which is unusual — most top-mount sinks at this size are 18-gauge or thinner
- Dual mount means the sink survives a future countertop replacement instead of being thrown away with it
- A 10-inch bowl with a rear-set drain leaves usable cabinet space under the front of the sink
- Grid, drain and strainer are in the box, so the only extra part is the sealant
What does not
- A 33-inch sink still needs a 36-inch cabinet, so it is not a drop-in replacement for a 30-inch base unit
- A 10-inch bowl is a long reach for a shorter person, and a drop-in rim sits slightly higher than an undermount one
- Kraus publishes no unit weight for this model, so plan the lift by the shipping box rather than a figure
Skip it if
Skip it if your existing cutout is for a 30-inch sink. A drop-in can cover a slightly smaller hole, never a smaller cabinet.

2. Best like-for-like swap
Kraus Premier KTM100-33
Kraus · Best for a like-for-like swap in an existing cutout
The plain, serviceable drop-in, and the one most likely to be a direct swap for what is already in your counter: 33 by 22 inches, a bowl 7-1/2 inches deep, 18-gauge Type 304 steel. The shallow bowl is the point — it is the depth older cabinets and high trap arms were built around, and it is getting hard to buy now that every new sink is ten inches deep.
Published specifications

- 33" x 22" x 8" source
- Bowl size
- 27-4/5" x 16" x 7-1/2" deep source
- Gauge
- 18 gauge, T-304 stainless steel source
- Faucet holes

- Mounting
- Drop-in / top mount, with a cut-out template in the box source
- Drain

- Sound damping
- NoiseDefend pads on all sides plus anti-condensation undercoating source
- Certification
- cUPC to ASME A112.19.3 / CSA B45.4, and MASS source
- Included
- Drain assembly with removable strainer, mounting hardware, cut-out template source
- Warranty
- Kraus limited lifetime source
What works
- A 7-1/2 inch bowl, which is the depth most older cabinets and shallow trap arms were built around
- A rear-set drain, so the trap sits at the back of the cabinet and leaves the front usable
- NoiseDefend pads on all sides rather than bottom pads only, which is unusual on an 18-gauge sink
- Drain assembly, strainer, hardware and a cut-out template are in the box, so the only extra part is the sealant
What does not
- 18-gauge flexes more than 16-gauge under a dropped pan, and the pads damp drumming rather than remove it
- Kraus does not publish a faucet-hole count for this model, so confirm the drilling matches your counter before ordering
- A 33-inch sink still needs a 36-inch cabinet, so it is not a swap for a 30-inch base unit
Skip it if
Skip it if you want a deep modern basin. At 7-1/2 inches the bowl will not take a sheet pan laid flat.

3. Best double bowl
Kraus KHT302-33 double-bowl drop-in sink
Kraus · Best for washing on one side, draining on the other
The double bowl for people who genuinely use two bowls — two equal 15-1/2 inch basins, both 10 inches deep, in the same 16-gauge dual-mount body as the single-bowl KHT300. Equal bowls are the right split if one side lives full of soaking dishes; a 60/40 split is the better choice if what you really want is one usable bowl.
Published specifications
- Overall size
- 33" x 22" x 10-5/8" deep source
- Bowl size
- Two equal bowls, 15-1/2" x 18" x 10" deep source
- Gauge
- TRU16 gauge stainless steel, 10:18 chromium-to-nickel source
- Mounting
- Dual mount — drop-in or undermount source
- Faucet holes
- Two pre-drilled, for a faucet and a soap dispenser source
- Minimum cabinet
- 36" source
- Sound damping
- NoiseDefend pads covering over 80% of the sink, plus undercoating source
- Certification
- cUPC to ASME A112.19.3 / CSA B45.4 source
- Included
- Two bottom grids, two drain assemblies with strainers, cut-out template, mounting hardware source
- Warranty
- Kraus limited lifetime source
What works
- Two 10-inch-deep bowls rather than one deep bowl and one token shallow one
- Pads over 80% of the body — the most complete damping of any sink on this page
- Both drains come with grids and strainers, which on a double bowl is normally two extra purchases
- Dual mount, so the same sink works on your existing counter now and an undermount counter later
What does not
- Each bowl is 15-1/2 inches wide, which will not take a large roasting pan flat — that is the cost of two bowls at 33 inches
- A center divider means the disposal lives under one side only, so decide which before you plumb it
- Two drain assemblies means two more joints under the sink that can weep
Skip it if
Skip it if you wash big sheet pans and roasting trays. One wide bowl beats two narrow ones for that, every time.

4. Best composite
Blanco Diamond Silgranit super single
Blanco · Best for hard water and visible sinks
The granite composite sink that answers the material's usual objection. Silgranit is up to 80% ground granite in an acrylic binder, and what it does better than stainless is hide everything: no water spots, no visible scratch pattern, no dent from a dropped pan. What it does worse is take a screaming-hot pan straight off the burner.
Published specifications
What works
- Hides limescale and water spotting better than any stainless finish — the reason to choose it in hard water
- Color runs through the material, so a scratch does not expose a different substrate
- Quieter than stainless without added pads, because the mass does the damping
- A 9-1/2" bowl is deep enough to lay a sheet pan flat
What does not
- Composite is not stainless: thermal shock is a real limit, so a very hot pan goes on a trivet
- Light colors show tea and turmeric staining more than dark ones
- Blanco publishes no thermal-limit figure, so we will not print one
Skip it if
Skip it if you routinely dump hot pans and boiling stock straight into the sink. Stainless tolerates that; composite is the wrong tool for it.

5. Best shallow and ADA
Kraus KWT310-33/5.5 ADA workstation drop-in sink
Kraus · Best for shallow cabinets and accessible kitchens
The drop-in to buy when depth is the problem rather than the goal. The bowl is 5.5 inches deep, which is what makes it ADA-compliant and also what makes it fit over a shallow trap arm — and it still carries a workstation ledge, so the cutting board and the drying rack recover the working space the shallow bowl costs.
Published specifications
- Overall size
- 33" x 22" x 6" deep source
- Bowl size
- 31" x 16" x 5.5" deep source
- Gauge
- TRU16 gauge stainless steel source
- Mounting
- Dual mount — drop-in or undermount source
- Faucet holes
- One pre-drilled, plus a soap-dispenser hole source
- Drain
- Rear offset source
- Minimum cabinet
- 36" source
- Compliance
- ADA; cUPC to ASME A112.19.3 / CSA B45.4 source
- Included
- Bottom grid, bamboo cutting board, roll-up drying rack, drain assembly, cut-out template source
- Warranty
- Kraus limited lifetime source
What works
- A 5.5-inch bowl clears plumbing that a 10-inch bowl simply will not — the commonest reason a sink upgrade stalls
- ADA-compliant depth, which matters if the kitchen has to be usable seated
- The integrated ledge and included accessories give back the working space the shallow bowl gives up
- Rear-offset drain, so the trap sits at the back of the cabinet rather than the middle
What does not
- 5.5 inches is genuinely shallow: a running faucet splashes more, and tall pots have to be filled at an angle
- The accessories are part of the price, and most households will not use all of them
- A shallow wide bowl shows standing water more obviously than a deep one, so the grid earns its place here
Skip it if
Skip it if you have the clearance for a deep bowl and nobody in the house needs an ADA-height basin. Buy depth instead.

Single bowl or double, at 33 inches
33 inches is exactly the width where this becomes a real argument. A single bowl gets you a 31 x 18 inch basin — big enough for a full-size baking sheet laid flat. Split the same shell into two and you get two 15-1/2 x 18 inch bowls, neither of which takes a sheet pan, in exchange for being able to wash on one side and drain on the other.
Our read is that a single bowl wins below about 33 inches and the argument is genuinely open at 33 and above. Single bowl vs double bowl is the full case, and best single bowl kitchen sinks is the shortlist if you have already decided.
Mounting: the detail that decides your counter
Three of the Kraus sinks here are dual mount, meaning the same sink can drop into a cutout with its rim on the counter or be undermounted beneath it. That flexibility is worth a lot on a replacement, because you can keep the installation you already have. The Kraus Premier KTM100-33 is specified as drop-in and top mount only, so its rim has to sit on the counter — which is exactly what you want when the counter is already cut for one.
If you are replacing like for like and not touching the countertop, drop-in is the low-risk route. If the counter is coming off anyway, undermount gives you a wipeable counter edge with no rim to catch crumbs. Drop-in vs undermount covers which your counter material will take.
Which one to buy
- Buy the Kraus KHT300-33 as the default: 16-gauge, 10-inch bowl, dual mount, grid and drain in the box.
- Buy the Kraus Premier KTM100-33 for a straight swap into an existing 33 x 22 cutout where the trap arm sits high — a 7-1/2 inch bowl in an 8 inch body is the shallowest option here.
- Buy the Kraus KHT302-33 if you want two bowls and have decided the sheet-pan compromise is acceptable.
- Buy the Blanco Diamond Silgranit if the sink is visible from the room and your water is hard — the composite hides limescale better than steel.
- Buy the Kraus KWT310-33/5.5 if the counter must be accessible, or if your base cabinet is unusually shallow.
If you are not committed to 33 inches yet, how to choose a kitchen sink runs the whole decision in order, and the best kitchen sinks is the main roundup across all sizes.
What to take away
- Every 33-inch sink here states a 36-inch minimum cabinet. A 33-inch sink does not fit a 33-inch cabinet.
- Measure the clear cabinet opening and the internal front-to-back depth, not the nominal cabinet width.
- At 33 inches the real decision is bowl depth: these five span 5.5 to 10 inches.
- A single 31 x 18 inch bowl takes a sheet pan flat; two 15-1/2 inch bowls do not.
- Dual-mount sinks can drop in or undermount, which is the safe choice on a replacement.
- Check what is in the box - grids, drains and templates are included on some of these and not others.

Common questions
- Will a 33 inch sink fit in a 33 inch cabinet?
- No. Every 33-inch sink on this page states a 36-inch minimum cabinet, because the cabinet needs side walls and the countertop needs a supported margin on each side of the cutout. A 33-inch cabinet takes a sink around 30 inches wide.
- Is 33 inches a standard kitchen sink size?
- It is the most common size in the US, usually as 33 x 22 inches, matched to a 36-inch base cabinet. That is why replacement choice is widest at this size and why a like-for-like swap is easiest here.
- How deep should a 33 inch kitchen sink be?
- Around 9 to 10 inches if you want a roasting pan to lie flat and you have a standard trap arm. Around 7-1/2 inches if your drain plumbing sits high or you would rather not reach down so far. Shallower than that is for accessible counters.
- Can I put a 33 inch sink in a 36 inch cabinet with a garbage disposal?
- Yes - that is the normal combination. What to check is vertical: a disposal adds 11-1/2 to 15 inches below the drain, so a 10-inch-deep bowl plus a tall disposal can foul the trap arm. Measure from the bottom of the sink to the drain line before ordering both.
