Will this fit my vanity?

Allow room for the 24-1/4 × 16-3/8-inch sink exterior, mounting hardware, drain and trap. Check the vanity opening, drawer clearance, countertop thickness and faucet placement before ordering. Use the actual sink and current Kohler cutout template before fabricating the countertop; exterior dimensions are not cutout dimensions.

Installation

Undermount installation. The sink has no faucet holes. The supplied drain operates with a counter-mounted faucet lift rod; verify faucet and drain operation together. Follow the manufacturer instructions for mounting, sealing and plumbing clearances.

Use the supplied sink clips with suitable countertop anchors and fasteners. The countertop fabricator should prepare the mounting points. Use 100% silicone sealant as directed; adhesive sealants are not a substitute for mechanical support.

For accessible installations, follow the model-specific clearance diagrams and applicable requirements for the complete installation, including counter height, knee space and plumbing protection.

Included in the box

  • Kohler K-21057-0 sink
  • Mounting clips
  • 1377123 lavatory drain with color-matched brass drain cover

Faucet, vanity and countertop shown in room photos are sold separately.

Installation supplies — sold separately

The drain and drain cover are included; no separate replacement drain is required for standard installation. Connecting plumbing, a suitable trap, 100% silicone sealant and countertop-specific anchors or support are sold separately. Use the current model-specific cutout template; do not size the opening from the product title.
