Taupe Basin Mat inside a monochrome clay kitchen, the only color in the room

A slow leak is the expensive kind.

It runs down the pipe to the lowest corner and works on the particleboard for weeks. Silicone turns that into a puddle you can see.

Sized by cabinet, not by guesswork

A wall, not a decorative edge.

The perimeter stands 0.75 inches and holds up to 2.5 gallons: a weeping trap, a seeping supply line, a bottle of cleaner on its side. All of it stays on the mat, in plain sight, until you wipe it up. That height is deliberate. It is the most water we can catch before the wall starts catching your cleaning bottles on the way in and out.

No grooves. One pass.

Textured patterns are marketing. The cells trap grime and the ridges tip bottles. A flat floor wipes clean and holds things level.

Questions, answered

What size under-sink mat do I need?
Go by your cabinet, not a universal size: a 24-inch sink base takes the 22 × 22 in mat; a 30-inch sink base takes the 28 × 22 in mat; a 33-inch sink base takes the 31 × 22 in mat; a 36-inch sink base takes the 34 × 22 in mat; a 30-inch vanity takes the 28 × 19 in mat; a 36-inch vanity takes the 34 × 19 in mat. If you are unsure, measure the flat interior floor side wall to side wall and front to back, or use the Fit Finder. Between sizes, go down.
How much water can an under-sink mat hold?
The Basin Mat's 0.75-inch silicone lip holds 1.6 to 2.5 gallons depending on size, enough to contain a slow leak or a tipped bottle of cleaner until you notice it.
Is a silicone mat better than a plastic drip tray?
A rigid tray is one shape for every cabinet and has to be trimmed or forced to fit. Silicone flexes past the cabinet face frame, lies on the floor instead of rocking on it, and is sold in sizes matched to real cabinet interiors. Basin's floor is smooth rather than ridged, so spills wipe off in one pass.
Will an under-sink mat fit around pipes?
Plumbing that comes down from the sink sits on top of the mat, so it is no obstacle. If pipes rise through the cabinet floor, measure depth to the front of the pipes and choose a mat that stops there. Most leaks start at the drain or disposal toward the front, so a shorter mat still sits under the part that leaks, with its lip intact.
What if I order the wrong size?
Every mat is fit guaranteed. If the size is wrong, exchanges are free in both directions: we send the right size and cover the return of the wrong one. Any-reason returns are open for 30 days.

Sixty seconds to a perfect fit.
