Measure around floor pipes
The mat sits beneath plumbing suspended above the cabinet floor. If pipes come through the floor, measure depth to the front of them and choose a mat that stops there, keeping the lip intact.
Asked before buying
My cabinet measures about 30.75 inches inside. Will it fit?
The mat measures 31 × 22 inches. Allow at least 31.25 × 22.25 inches of clear interior floor for installation. Measure inside the cabinet, not across the doors. If either measurement is smaller, use the Fit Finder to choose a mat that fits both dimensions.
Does the plumbing get in the way?
Plumbing suspended above the cabinet floor can sit above the mat. If pipes rise through the floor, measure usable depth to the front of those pipes and choose a mat that stops there with its raised lip intact. Do not assume a full-depth mat fits around floor-mounted pipes.
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.
