A standard 36-inch bathroom vanity cabinet has an interior of about 34.25 inches. The Basin Mat for this cabinet measures 34 × 19 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 2.2 gallons the night the plumbing lets you down.

Pipes are fine

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 33.75 inches inside. Will it fit?
The mat is 34 × 19 in, so it needs at least 34.25 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 34 × 19 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 36-inch vanity a standard size?
Yes. The 36-inch vanity is one of the most common bathroom vanity widths in US homes, which is exactly why we make a mat for its 34.25-inch interior.
