Xtreme Mats Waterproof Undersink Mat — Beige 34" x 22.25" (Fits 36" Cabinet) | 3.6 Gal Capacity, Flexible Leak Protector

The Xtreme Mats Waterproof Undersink Mat is a flexible, high-capacity cabinet liner that captures leaks and spills to protect kitchen and laundry cabinets from water and chemical damage.

This durable beige liner measures to fit a 36-inch cabinet base opening when trimmed to 34" x 22.25" and is engineered as an all-in-one driptray, shelf liner, and under-sink protector. Made from low-density polyethylene, the mat combines a textured floor, angled sidewalls, and a high liquid-holding capacity so you can install it in tight spaces and trust it to contain accidental leaks until you can clean them up.

How much liquid can the mat hold if a leak occurs?

The Xtreme Mats undersink mat is designed to capture multiple gallons of liquid, giving you time to discover and address leaks without immediate cabinet damage. Its raised sidewalls and low-density polyethylene construction maintain integrity even when supporting pooled liquid.

• Industry-leading capacity: holds up to approximately 3.6 gallons of liquid.
• Angled, raised sidewalls prevent overflow onto cabinet floors.
• Textured surface keeps stored items stable and avoids shifting in pooled liquid.

Will it fit my cabinet and how easy is it to install?
