The Basin Mat for this cabinet measures 31 × 22 in, covering the full floor with an even 0.125-inch installation gap on each side. Nothing to trim, nothing to cut, and a 0.75-inch lip that holds 2.3 gallons the night the plumbing lets you down.

The mat slides in around the P-trap and supply lines and sits beneath them. You are covering the cabinet floor, not re-plumbing the sink.
Asked before buying
My cabinet measures about 30.75 inches inside. Will it fit?
The mat is 31 × 22 in, so it needs at least 31.25 inches of flat interior width. If you measured under that, size down one: the fit guarantee covers you either way with free exchanges.
Does the plumbing get in the way?
No. The drain and supply lines land on top of the mat. The 31 × 22 in floor covers the cabinet bottom fully, and the silicone conforms around fixed hardware bases.
Does it arrive folded?
Yes, it ships folded and relaxes once it is in the cabinet. Faint creases from packaging may remain, and they do not affect the mat's performance in any way.
Is a 33-inch sink base a standard size?
Yes. The 33-inch sink base is one of the most common kitchen cabinet widths in US homes, which is exactly why we make a mat for its 31.25-inch interior.
