Quick answer from a licensed plumber: For a stainless farmhouse sink in a 33-inch cabinet, the Kraus KHF200-33. For white fireclay, the Kraus Turino KFR1-33GWH, reversible with a rounded or flat apron. For two bowls, the Kraus KHF203-33. For black or matte granite composite with workstation accessories, the Ruvati RVG1533BK in a 36-inch cabinet. Every one needs cabinet work and supports inside the cabinet.
Our pick for most kitchens: the Kraus KHF200-33 16 gauge stainless apron-front sink, which fits a 33-inch cabinet. Check the Kraus KHF200-33 on Amazon
A farmhouse sink, also called an apron-front sink, has a finished front panel that replaces the top of the cabinet face. That one detail drives the whole purchase: the cabinet has to be built or cut for it, and the sink has to sit on supports inside the cabinet. This page covers 33-inch apron-front sinks in the three common materials: stainless, fireclay and granite composite. Every spec comes from the makers’ own pages, spec sheets and installation manuals. For other sink styles, see our best kitchen sinks guide.

From Kraus and Ruvati product pages, spec sheets and manuals linked below. On October 5, 2026, every linked listing was in stock and sold by Amazon.com, except the Ruvati, which was sold by Ruvati’s own Amazon store. Several of the Kraus listings were low on stock when we checked.
Pick the Material First
- Stainless steel: the Kraus KHF picks are 16 gauge with sound pads, a limited lifetime warranty and the smallest cabinet requirement here, 33 inches.
- Fireclay: the white, glazed look. Kraus rates its Turino to 300°F. Each sink varies slightly, so the cabinet and countertop are cut to the actual sink, and Kraus warrants it for 5 years.
- Granite composite: matte and colored all the way through. Ruvati rates its RVG1533 to 356°F and says not to set hot pots on it.
Our stainless vs granite composite vs fireclay comparison goes deeper on scratches, heat, stains and cleaners for each material.
The Cabinet Is the Real Project
An apron-front sink does not drop into a standard sink base. Kraus says its farmhouse sinks need a farmhouse cabinet or a modified existing cabinet. Both makers’ guides follow the same order:
- Measure the actual sink. Kraus and Ruvati both say to measure the apron height on the sink in hand. Kraus’s fireclay spec sheet notes a typical ±3 mm side wall variance.
- Build supports inside the cabinet. Kraus lists 1-1/4-inch angle irons, 2x4s or 3/4-inch plywood. Ruvati calls for a 2×4 frame and says the cabinet and frame should hold up to 200 pounds once installed.
- Cut the cabinet front. Kraus says to add 1/16 inch to the apron height when you mark the cutout.
- Set and level the sink, then cut and set the countertop over it with a bead of silicone.
The minimum cabinet differs by sink. The Kraus stainless picks need 33 inches wide and 24 inches deep. The Ruvati needs 36 inches. Kraus’s fireclay pages give both numbers, so plan on 36.
Reveal and countertop
The reveal is how much of the sink rim shows past the countertop edge. Kraus’s stainless cutout template has lines for a 1/8-inch negative reveal, a flush reveal and a 3/8-inch positive reveal. For the fireclay Turino, Kraus recommends about a 1/8-inch positive reveal. Ruvati recommends a 1/4-inch reveal. Kraus says its farmhouse sinks are not well suited to laminate or tile counters.
Drain, Disposal and Trap
All four sinks have a 3-1/2-inch drain opening, the standard size for a basket strainer or a disposal. Kraus says a disposal replaces the sink drain and mounts with its own flange; Ruvati says the same for the RVG1533. Where the drain sits matters for the cabinet: Kraus puts the KHF200-33 drain center 4-1/2 inches from the back wall of the sink, and the fireclay Turino’s center drain 7-3/4 inches from it.
Plumber’s note: a 10-inch-deep bowl with a garbage disposal under it takes up a lot of height in the cabinet. Before the countertop goes on, check that the trap arm can still reach the wall drain with proper fall. If it cannot, the wall drain may have to be lowered.
Kraus Standart PRO KHF200-33 33-Inch Apron Front Single Bowl Sink
16 gauge T304 stainless · 32-7/8 x 20-3/4 in. outside · bowl 30 x 16 in., 10 in. deep · 9 in. apron · rear center 3-1/2 in. drain, 4-1/2 in. from the back wall · 33 in. minimum cabinet, 24 in. front to back · NoiseDefend pads and undercoating · cUPC · Kraus limited lifetime warranty
If you want a farmhouse sink that Kraus says resists dents and damage, start with stainless. Kraus lists the KHF200-33 in 16 gauge T304 stainless with a single 30 x 16-inch bowl, 10 inches deep, and a 9-inch apron. Kraus’s page lists a 10-1/2-inch outside depth; its spec sheet and manual give the sink as 10 inches. It needs only a 33-inch base cabinet, which Kraus gives as 33 inches left to right and 24 inches front to back. Kraus says its NoiseDefend pads cover over 80 percent of the sink, with an undercoating against condensation.
The drain is rear center, and Kraus says the drain center is 4-1/2 inches from the back wall of the sink. Kraus says the rear-set drain maximizes storage space in the base cabinet. Kraus says a disposal replaces the strainer and mounts to the sink with its own flange. One documentation conflict: Kraus’s feature list says mounting hardware is in the kit, but its own questions section says this sink does not include mounting hardware, and the spec sheet lists only the strainer, grid, template and towel. Plan to build supports in the cabinet either way.
- 16 gauge stainless, per Kraus
- Fits a 33-inch base cabinet
- Strainer, bottom grid and cutout template included, per the spec sheet
- Kraus limited lifetime warranty
- Kraus documents conflict on mounting hardware
- Needs a farmhouse cabinet or a modified cabinet, per Kraus
- Not well suited to laminate or tile counters, per Kraus
Verdict: The pick for a stainless apron-front sink in a 33-inch cabinet.
Kraus Turino KFR1-33GWH 33-Inch Reversible Fireclay Farmhouse Sink
Fireclay, made in Italy · 33 x 18-1/4 x 10 in. outside · bowl 30-1/4 x 15-1/2 in., 8-7/8 in. deep (spec sheet; Kraus’s page says 9 in.) · reversible: rounded or flat apron · center 3-1/2 in. drain opening, 7-3/4 in. from the back wall · heat resistant to 300°F, per Kraus · bottom grid included · no cutout template · cUPC · Kraus 5-year limited warranty
This is the white farmhouse sink most people picture. Kraus makes the Turino in Italy from fireclay with a kiln-fired enamel finish, and says it is heat resistant up to 300°F. It is reversible: one side has a rounded, traditional apron and the other a flat, modern one, so you choose before it goes in. The drain opening is 3-1/2 inches and center set, 7-3/4 inches from the back wall per Kraus.
Fireclay is not cut to a template. Kraus says no cutout template is included, because fireclay sinks may vary slightly in size, and its spec sheet notes a typical ±3 mm side wall variance. Kraus recommends giving the cabinet maker the actual sink before the cabinet is built, and an approximately 1/8-inch positive reveal at the countertop. Kraus’s documents conflict on the cabinet: the product page says a 36-inch minimum, while the spec sheet and questions say 33 inches. They also conflict on the drain: the product page says a drain assembly comes with it, but the spec sheet and manual list only the bottom grid, and the Amazon listing names compatible Kraus drains. Plan on a 36-inch cabinet and buying a drain.
- Reversible rounded or flat apron, per Kraus
- Heat resistant to 300°F, per Kraus
- Gloss white or matte white finish
- Bottom grid included
- 5-year limited warranty, not lifetime like the Kraus stainless
- Kraus documents conflict on cabinet size (33 vs 36 in.) and on whether a drain is included
- No template: the cabinet and countertop are cut to the actual sink
Verdict: The pick for a white fireclay apron-front sink, if the cabinet is built or cut to the sink in hand.
Kraus Standart PRO KHF203-33 33-Inch Apron Front 60/40 Double Bowl Sink
16 gauge T304 stainless · 32-7/8 x 20-3/4 in. outside · bowls 17-3/8 x 16 in. and 11-5/8 x 16 in., 10 in. deep · 9 in. apron · two rear center 3-1/2 in. drains · 33 in. minimum cabinet, 24 in. front to back · NoiseDefend pads and undercoating · cUPC · Kraus limited lifetime warranty
For people who wash in one bowl and rinse or stack in the other, this is the same Kraus Standart PRO farmhouse in a 60/40 split. Kraus lists a 17-3/8 x 16-inch large bowl and an 11-5/8 x 16-inch small bowl, both 10 inches deep, in the same 32-7/8 x 20-3/4-inch outside size and 33-inch minimum cabinet as the single bowl.
Two bowls mean two drains, each 3-1/2 inches and rear center per the spec sheet, so the cabinet has two tailpieces to tie into one trap. Kraus says a disposal can go on either side. The kit includes two bottom grids, a basket strainer and a second strainer, a template and a towel, per Kraus. The same mounting-hardware conflict applies as on the single bowl: the feature list includes it, the questions section says it does not.
- 60/40 split for washing and rinsing
- Fits a 33-inch base cabinet
- Two bottom grids and two strainers, per Kraus
- Kraus limited lifetime warranty
- Smaller bowls than the single bowl for big pans
- Two drains to plumb into one trap
- Kraus documents conflict on mounting hardware
Verdict: The pick for a two-bowl apron-front sink in a 33-inch cabinet.
Ruvati epiCast RVG1533BK 33-Inch Granite Composite Farmhouse Workstation Sink
Granite composite, 80% crushed natural granite, made in Italy · 33 x 20-1/2 in. outside, 9-3/8 in. apron · bowl 29-3/4 x 16 in., 9 in. deep · reversible rounded or sharp-corner apron · front and back ledges for the included cutting board and drying rack · rear center 3-1/2 in. drain · 36 in. minimum cabinet · heat to 356°F, per Ruvati · CSA certified to UPC · Ruvati limited lifetime warranty (residential)
If you want a black or gray farmhouse sink, or a matte finish, granite composite is the material. Ruvati says the RVG1533 is 80 percent crushed natural granite, made in Italy, colored all the way through, and can withstand up to 356°F. It is also a workstation sink: ledges on the front and back carry the included cutting board and folding drying rack. Like the Kraus Turino, it is reversible, with a rounded-corner apron on one side and a sharp-corner apron on the other.
Ruvati sells it through its own Amazon store. Ruvati says the 3-1/2-inch drain opening fits any garbage disposal, but its strainer is only for a standard install; with a disposal, you use the flange that comes with the disposal. It needs a 36-inch base cabinet. One documentation conflict: Ruvati’s product page calls it an undermount apron-front sink, while its spec sheet lists the installation type as topmount; Ruvati’s farmhouse guide has you set the sink on a frame and seal the countertop down onto its rim. Ruvati also says not to set hot pots straight on the sink; the bottom of a pot off the burner can pass 600°F.
- Black, gray or white matte granite composite, per Ruvati
- Workstation ledges with cutting board and drying rack included
- Drain opening fits a disposal, per Ruvati
- Ruvati limited lifetime warranty for residential use
- Needs a 36-inch base cabinet
- Ruvati’s page and spec sheet disagree on undermount vs topmount
- Accessories are not covered by the warranty, per Ruvati
- No cutout template, per Ruvati
Verdict: The pick for a dark or matte farmhouse sink with workstation accessories, in a 36-inch cabinet.

Before You Buy
- Read the minimum cabinet. 33 inches for the Kraus stainless picks, 36 for the Ruvati, and plan on 36 for the Kraus fireclay.
- Decide who builds the cabinet. Kraus and Ruvati both expect the cabinet to be built or cut to the actual sink.
- Choose stone or solid surface. Kraus says its farmhouse sinks are not suited to laminate or tile counters.
- Read the warranty fine print. Kraus’s current kitchen sink warranty covers the original purchaser for personal household use, for as long as that purchaser lives in the home where the sink was first installed. It is not transferable, and commercial use gets 1 year. The fireclay Turino’s warranty runs 5 years, with the same original-purchaser, household-use and 1-year commercial terms. The sink warranty printed in Kraus’s KHF manual says it does not apply unless a fully insured and licensed trade professional installs the sink; Kraus’s current warranty document says Kraus recommends one. Both refer to buying from an authorized Kraus dealer, and Kraus does not say whether Amazon counts, so ask Kraus if the warranty matters to you. Ruvati’s covers the original purchaser and residential use only, and excludes accessories.
- Check the cleaner rules. Kraus’s warranty documents say abrasive cleaners (they list powders, bleach, ammonia, alcohol and chlorine), abrasive pads and steel wool void the warranty, while Kraus’s product pages recommend Bar Keepers Friend and a fine Scotch-Brite pad. Ask Kraus which applies before you use either. Ruvati says not to use steel wool or abrasive cleaners on its granite sink, and never to pour bleach or let drain cleaner touch it.
- Buy the drain if you need one. The Kraus fireclay documents disagree on whether a drain is included.
Installing a Farmhouse Sink
The order matters: sink before countertop. Kraus and Ruvati both have you build the supports, set and level the sink, then cut the countertop and press it down onto a bead of silicone on the sink rim. Kraus says to inspect the sink for shipping damage before installing it, and Ruvati says to inspect it immediately on delivery. Ruvati says no cutout template is provided for its farmhouse sinks; Kraus includes one for the stainless KHF sinks but not for the fireclay Turino.
Kraus recommends hiring a licensed professional for its sinks, and Ruvati recommends a professional installer. Once the sink is set, the plumbing is a standard kitchen hookup: strainer or disposal, tailpiece, trap and supply lines. Our guides to kitchen sink basket strainers and a kitchen sink leaking underneath cover those parts.
FAQ
What size cabinet does a farmhouse sink need?
Check the maker’s minimum, not the sink length. Kraus lists 33 inches wide and 24 inches deep for its 33-inch KHF200-33 and KHF203-33. Ruvati lists 36 inches for its 33-inch RVG1533. Kraus’s pages give both 33 and 36 inches for the fireclay Turino KFR1-33, so plan on 36.
Can I put a farmhouse sink in my existing cabinet?
Only with cabinet work. Kraus says its farmhouse sinks need a farmhouse cabinet or a modified existing cabinet for the apron, and its manuals have you cut the cabinet front to the apron height plus 1/16 inch and build supports inside. Ruvati says to have an experienced cabinet maker build or modify the cabinet using the actual sink.
How do you support a farmhouse sink?
With a frame inside the cabinet, not the countertop alone. Kraus lists 1-1/4-inch angle irons, 2x4s or 3/4-inch plywood as support options. Ruvati says to build a 2×4 frame and that the cabinet and frame should hold up to 200 pounds once installed, with the sink rim level and flush with the top of the cabinet.
Can a farmhouse sink have a garbage disposal?
Yes, for every sink on this page. Kraus says a disposal replaces the drain and mounts to the sink with its own flange. Ruvati says the RVG1533’s 3-1/2-inch drain opening fits any disposal, using the flange that comes with the disposal instead of the sink’s strainer.
Does a farmhouse sink work with a laminate countertop?
Kraus says no: its farmhouse sinks are best with solid surfaces like marble, concrete, soapstone and granite, and not well suited to laminate or tile, whose seams have too many weak points to support the sink. Ruvati’s guide covers laminate only to say the exposed cut edges must be finished and sealed.

Bottom Line
Buy the Kraus KHF200-33 for a 16 gauge stainless farmhouse sink in a 33-inch cabinet, the KHF203-33 if you want two bowls, the Kraus Turino for white fireclay, and the Ruvati RVG1533BK for a matte granite workstation sink. Whichever you choose, have the actual sink on hand before the cabinet is cut, build supports for it, and use a stone or solid-surface countertop.
