Measure First: The Best 33 Inch Kitchen Sink for a 36-Inch Cabinet

Thirty-three inches is one of the most common kitchen sink widths, and the makers below explain why: each one that lists a cabinet size pairs its 33-inch sink with a 36-inch sink base cabinet. If you are replacing an old drop-in sink, or the countertop template already says 33, the real choice is not the size but what goes in that space: one wide bowl or two, steel or stone, a sink that sits on the counter or one that hangs below it.

This guide stays inside that one size. Every sink below is a 33-inch model from a named maker, with the bowl layout, depth, gauge and cabinet requirement taken from the maker’s spec sheet or the Amazon listing, and “not stated” where neither says. If you have not settled on one bowl versus two, our guide to the best single bowl kitchen sink covers that question across all sizes.

Quick verdict: which 33-inch sink to buy

Our single-bowl guide already reviews the Ruvati RVH8222 workstation sink, the Kraus Kore 33-inch farmhouse and the Logmey 33-inch farmhouse, so none of those appear again here; this page adds double bowls, drop-in replacements and composite sinks to the 33-inch choice.

Our picks for the best 33 inch kitchen sink

These seven cover the real choices at this width: one bowl or two, undermount or drop-in, stainless, composite or fireclay. Each pick says who it suits and gives one honest reason to skip it.

How to choose a 33-inch kitchen sink

Measure the cabinet, not just the counter

Every maker here that states a figure lists a 36-inch minimum base cabinet for its 33-inch sink. The cabinet walls take up space, and the sink needs clearance for clips or a rim, so a 33-inch sink will not go into a 33-inch cabinet. Open the doors and measure the inside width, then check the cutout template that comes with the sink before anyone cuts stone.

Drop-in, undermount or dual mount

A drop-in sink hangs from its rim and works with any counter, including laminate; it is the easy swap. An undermount sink is clipped under a solid-surface counter, so you can wipe crumbs straight in, but it needs stone, quartz or solid surface. Dual-mount sinks like the Kohler Task, Kohler Verse, Kohler Kennon and Blanco Liven can go either way, which is useful if new counters are a few years off.

One bowl or two at 33 inches

At this width, one bowl gives you about 30 inches of open space for sheet pans, a roasting rack or a tamale steamer. Two bowls let you soak in one and rinse in the other. A low divider, like Ruvati’s, splits the difference. Our single-bowl sink guide covers that choice in more depth.

Depth and gauge

Depth decides whether a big pot fits under the faucet and how much splash you get. The stainless sinks here run from 9 inches (Kohler Task and Verse) to 10 inches (both Ruvati stainless sinks). For stainless, a lower gauge number means thicker steel: 16 gauge is thicker than 18, and 18 is thicker than 22. Thicker steel tends to dent less and ring less, but makers’ sound pads also matter.

Stainless, composite or fireclay

Stainless steel is the lightest and the most forgiving with pots. Granite and quartz composites such as Blanco SILGRANIT and Kohler Neoroc are quieter and come in colors, though light colors can show stains. Fireclay is heavy, glossy and suits a farmhouse kitchen, but needs a sturdy cabinet. Whatever you choose, check that your faucet’s hole count matches the sink; see our best kitchen faucet guide if you are replacing both.

What comes in the box

Workstation sinks like the Kohler Task and Ruvati RVH8003 include colanders and cutting boards that fit the ledge; others include only a grid and strainer, or nothing at all. Count those extras when comparing sinks, since a matching grid can be a separate purchase.

How we chose these seven 33-inch sinks

We looked for 33-inch kitchen sinks from named makers (Kohler, Blanco and Ruvati) that Amazon showed as in stock when we checked, and chose one for each real choice at this width: single or double bowl, drop-in or undermount, stainless, composite or fireclay. Specifications come from the Amazon listings and the makers’ spec sheets; where the Amazon listing was thin, as with the Blanco Liven, we used published retailer spec listings and say so. We left out anonymous Amazon-only brands, and our searches turned up no Franke or Moen 33-inch sink showing normal stock.

We have not installed or used these sinks ourselves. We also searched the U.S. Consumer Product Safety Commission’s recall listings for these makers and found no kitchen sink recalls; the Kohler and Elkay recalls that did appear there covered shower doors, bath doors and water coolers, not sinks.

33-inch sink questions, answered

What size cabinet do I need for a 33-inch sink?

Every maker here that lists one asks for a 36-inch base cabinet. Measure the inside of your cabinet and compare it with the sink’s cutout template before buying.

Is 33 x 22 a standard sink size?

Yes. It is the common outside size for drop-in kitchen sinks in the U.S., which is why the Ruvati RVH8003, Kohler Verse, Kohler Kennon and Blanco Liven all share it. Undermount sinks are often shallower front to back, such as the Ruvati RVH7419 at 33 by 19 inches.

Can I put an undermount sink in a laminate counter?

Generally no; undermount sinks need a solid-surface counter such as granite, quartz or solid surface. With laminate, choose a drop-in sink or a dual-mount model installed from the top.

Is a single or double bowl better at 33 inches?

A single bowl gives more room for sheet pans and big pots; a double bowl suits hand-washing. A low-divide double, like the Ruvati 60/40, is a compromise that lets long pans span both sides.

Do fireclay and composite sinks chip or stain?

Ruvati describes its enamel-finished fireclay as resistant to chips and scratches, and Blanco and Kohler describe their composites as stain- and scratch-resistant. Light colors can still show dark food stains more readily than black or gray, so wipe them after cooking with chiles or turmeric.

Our last word on 33-inch sinks

For most kitchens with a 36-inch cabinet, the Kohler Task 33-inch Workstation Sink is the best all-round choice. Pick the Ruvati 60/40 Low-Divide for two bowls, the Ruvati RVH8003 for a drop-in workstation, the Blanco Liven or Kohler Kennon for a composite, the Kohler Verse for a dual-mount double, and the Ruvati fireclay for an apron front. For other sizes, start with our best single bowl kitchen sink guide, and look at our under-sink water filters for the cabinet below and our dish racks for the counter beside it.
