XTREME MATS Waterproof Undersink Mat 22 in - Leak Protection

In this review the XTREME MATS Waterproof Undersink Mat is evaluated as a practical, no-nonsense solution for protecting cabinet bases from plumbing leaks and spills. Designed as the ORIGINAL under sink mat, it is aimed at homeowners and renters who want a simple way to prevent water damage and contain messy spills; the single biggest reason to buy is its ability to hold up to 3.6 gallons of liquid, which turns a common leak into a manageable cleanup rather than a costly repair. The reviewer found it easy to install, durable in daily use, and particularly useful where cabinets store cleaning products or are prone to slow drips.

Key Features

• Perfect Fit: Available in sizes intended for kitchen and bathroom cabinets so it sits neatly under most sinks without bunching or trimming in many installations.
• High Capacity: The molded pan design holds up to 3.6 gallons of liquid, giving lengthy protection during a leak and time to notice and address plumbing issues.
• Durable & Flexible: Made of low-density polyethylene, it is flexible enough to install through small openings yet sturdy enough to keep its shape and contain spills.
• Raised Side Walls: Angled, tall sides and a textured surface help keep stored items dry and prevent liquids from reaching cabinet interiors or floors.
• Easy Maintenance: The mat is simple to remove, rinse, and replace for quick clean-up after spills or routine cabinet cleaning.
• Designed in USA: Engineered by an American company with a lifetime limited warranty against manufacturing defects.

Who It's For

The XTREME MATS Undersink Mat is ideal for homeowners, renters, and vacation property managers who want a low-effort way to protect cabinetry from leaks, chemical spills, or drips around plumbing. It suits kitchens and bathrooms where cabinets store cleaners, bottles, or plumbing fixtures that occasionally drip.

Those who should look elsewhere include owners whose cabinet plumbing enters through the floor and cannot be accommodated without cutting or modifying the mat, or buyers who require rigid pans with built-in drains or electrical leak alarms (the manufacturer sells a separate water sensor). If precise custom dimensions are needed, contact the maker for guidance before ordering.

Pros & Cons

Pros

• Fits quickly and finishes off the cabinet area neatly, with no joints or seams to trap grime.
• Strong containment thanks to raised, angled side walls and a textured surface that keep items from getting wet.
• Flexible enough to install through narrow openings yet sturdy enough to support gallons of water without collapsing.

Cons

• Requires measurement and possible modification if plumbing comes through the cabinet floor, which adds a step for some installs.
• Water sensor not included, so buyers who want alerts will need to purchase a separate device.

Frequently Asked Questions

Will the mat hold standing water from a slow leak?
The molded pan can contain up to 3.6 gallons, so it will hold standing water from many slow leaks long enough for you to spot and clean up.

Can it be used in cabinets with plumbing coming through the base?
Measure your cabinet first; if the supply lines or drain come through the floor, the mat may need modification and you should contact the company for guidance.

Is a leak sensor included?
No, the water sensor is sold separately, though the mat is compatible with external sensors placed inside the pan.
