For the deepest bowl, pick a Kohler Ladena: the K-2214 for a standard vanity or the K-2215 for a wide one. For straight vertical sides, pick the Verticyl K-2882. To match Archer pieces, pick the Archer K-2355.

| Sink | Outside size | Bowl (L x W) | Water depth | Basin shape |
|---|---|---|---|---|
| Verticyl K-2882 | 19-13/16 x 15-5/8 in. | 17-1/4 x 13 in. | 3-1/8 in. | Vertical sides |
| Ladena K-2214 | 20-7/8 x 14-3/8 in. | 18-5/8 x 12-1/4 in. | 4-5/8 in. | Curved bottom |
| Ladena K-2215 | 23-1/4 x 16-1/4 in. | 20-5/8 x 13-5/8 in. | 4-5/8 in. | Curved bottom |
| Archer K-2355 | 19-7/8 x 15-5/16 in. | 17-5/8 x 13 in. | 3-3/4 in. | Rectangular |
All four are undermount sinks: they mount under the counter, usually stone or solid surface, and the counter is cut to Kohler’s template. None has faucet holes, so the faucet goes in the counter or on the wall. Each sheet lists the KOHLER One-Year Limited Warranty and a required cutout template; three sheets say it is not included, and the Archer sheet is mixed, as noted below.
Kohler Verticyl K-2882: straight sides, shallowest bowl
Choose the Verticyl K-2882 for a rectangle with vertical sides in a standard vanity. Kohler’s spec sheet (resources.kohler.com) lists a geometric rectangular basin with vertical sides, an overflow, no faucet holes and included 1193643 basin clamps. The drawing shows 19-13/16 by 15-5/8 inches outside, a 17-1/4 by 13-inch bowl, a 3-1/8-inch water depth and a 6-3/4-inch overall depth. The template is 1109226-7, required and not included.
The water depth is the shallowest of the four, so check that your faucet’s stream lands in the bowl without splashing.

Kohler Ladena K-2214: deeper curved bowl, 21 inches
Choose the Ladena K-2214 for a deeper curved bowl in a 21-inch footprint. Kohler’s spec sheet (resources.kohler.com) lists a rectangular basin with a curved bottom, an overflow, no faucet holes and a 1193643 clamp assembly. The drawing shows 20-7/8 by 14-3/8 inches outside, an 18-5/8 by 12-1/4-inch bowl and a 4-5/8-inch water depth. The template is 1053195-7, required and not included. Kohler’s diagram is based on its K-8998 adjustable P-trap with 1 inch of tailpiece showing.
On October 15, 2026, the standard new offer sold by Buildcom showed In Stock with model 2214-0, white.

Kohler Ladena K-2215: the largest bowl
Choose the Ladena K-2215 for the biggest bowl here, if the vanity is wide and deep enough. Kohler’s spec sheet (resources.kohler.com) lists the same curved-bottom Ladena basin in a larger size: 23-1/4 by 16-1/4 inches outside, a 20-5/8 by 13-5/8-inch bowl and the same 4-5/8-inch water depth. It includes 1193643 basin clamps. The template is 1002977-7, required and not included.
Because the outside is 16-1/4 inches front to back, check the space between the faucet location and the counter edge on a narrow vanity top.

Kohler Archer K-2355: classic rectangle, matches Archer
Choose the Archer K-2355 if you are matching other Archer pieces. Kohler’s spec sheet (resources.kohler.com) lists a classic rectangular basin, an overflow, no faucet holes, included 1193643 basin clamps and a note that it coordinates with other products in the Archer collection. The drawing shows 19-7/8 by 15-5/16 inches outside, a 17-5/8 by 13-inch bowl and a 3-3/4-inch water depth. The drop-in Archer sink is a different model, covered in our drop-in bathroom sink guide.
One conflict on the sheet: the table lists template 1224722-7 as required, not included, while the notes tell the counter cutter to use the template provided with the product or a current one from Kohler. Ask your counter fabricator to get the current template from Kohler either way.

Check these before you order
- Counter material. Undermount sinks are usually set under stone or solid-surface counters. The Ladena and Archer sheets show marble and wood installation details with sealant.
- Template. The cutter must use Kohler’s current template for the exact model. Kohler says it is not responsible for cutout errors when the wrong template is used.
- Faucet. With no faucet holes, you need a single-hole, widespread or wall-mount faucet drilled into the counter or wall. See our single-hole bathroom faucet guide.
- Drain. All four have a 1-3/4-inch drain hole and an overflow, so use a drain with an overflow opening.
- Mounting. Three sheets list included 1193643 basin clamps; the K-2214 sheet lists a 1193643 clamp assembly. Our undermount sink adhesive guide covers the sealant side.
Depth under the counter and drawer space
An undermount sink hangs below the counter, and its full depth matters if the vanity has a top drawer or a shelf. The drawings show the overall depth of the sink body below the rim: about 6-3/4 inches for the Verticyl K-2882, 7-1/2 inches for the Archer K-2355 and 8-1/8 inches for the Ladena models.
Add the tailpiece and P-trap below that. Kohler’s Ladena drawings assume its K-8998 adjustable P-trap with 1 inch of tailpiece showing, and each drawing places the 3/8-inch hot and cold supply stubs 14 inches below the rim and 4 inches apart, with a 1-1/4-inch outlet between them. If the vanity has a false drawer front at the top, measure the open space behind it before you choose the deeper Ladena.
Each sheet also shows a recommended ADA layout with the rim no higher than 34 inches and at least 27 inches of knee clearance, if you are planning an accessible bathroom.
Warranty and color notes
Every Kohler sheet here lists the KOHLER One-Year Limited Warranty. Some Amazon listings describe a lifetime warranty; we go by Kohler’s sheet. The sheets list color codes beyond white: 96 Biscuit, NY Dune, 95 Ice Grey, 58 Thunder Grey and 7 Black Black, with the Verticyl also listing 17 Teal and 42 Aspen Green. The offers linked here are all white (color code 0). For other brands and sizes, see our undermount bathroom sink guide.
