Kitchen Sink Installation Guide
Choosing between an undermount, drop-in, and farmhouse kitchen sink? Start with your countertop and cabinet. If you are replacing an existing sink, check the opening before choosing a new model.
Undermount
The sink mounts below the countertop, leaving the countertop edge visible around the opening. Ask your installer whether your countertop material and construction support this installation. Check the model’s cutout shape, how much of the sink rim will be visible, and the space required for mounting hardware.
Drop-In
The sink fits into the countertop opening with its rim resting on top. For a replacement, confirm that the new rim covers the existing opening and that the opening, corner shape, and mounting clips match the model’s requirements. Two sinks with the same advertised width can have different cutouts.
Farmhouse / Apron-Front
The front apron is visible above the cabinet doors. Verify the apron opening, cabinet support, and door clearance before ordering. Farmhouse describes the front of the sink. Follow your model’s instructions to determine how it mounts to the countertop.
What about dual-mount sinks?
Some models support both drop-in and undermount installation. Choose your installation method first, then use the corresponding cutout and mounting instructions for that model.
Before you order
- Check the exact model’s installation options and minimum cabinet size.
- Confirm the countertop opening and room for mounting hardware.
- Allow clearance for the faucet, drain, plumbing, and any garbage disposal.
- Have your installer verify fit and support before cutting the countertop or cabinet.
If you are unsure, send Kichae your product link or SKU, cabinet measurements, and photos of the existing setup.
