GORILLA GRIP Waterproof Silicone Under Sink Mat 31 x 22 in - Leak

In this review the GORILLA GRIP Waterproof Silicone Under Sink Mat is evaluated as a practical cabinet protector for kitchens, bathrooms, and laundry rooms; it is aimed at homeowners and renters who want a low-maintenance barrier against leaks and accidental spills. The single biggest reason to buy is its 100% waterproof construction combined with a reinforced 0.7 in raised lip that contains liquid and helps keep cabinetry dry, and the mat is also dishwasher safe for quick cleaning after messy leaks.

Key Features

• 100% Waterproof: The silicone creates a reliable barrier between liquids and cabinet surfaces to reduce water damage risk.
• Dishwasher Safe: The mat can be cleaned quickly in a dishwasher, making it easy to remove stains and residue after spills.
• BPA Free and Stain Resistant: Made from BPA free silicone that resists staining from common household spills and is safer for use around food storage and cleaning supplies.
• Reinforced Raised Lip: The 0.7 in raised lip is reinforced with added strips so it keeps its shape and helps contain leaks without tearing.
• Stays in Place: Raised silicone dots on the topside and a flat profile help the mat grip the cabinet floor so items do not slide during daily use.
• Multiple Uses: Sized at 31 x 22 in, it fits standard under sink spaces and can be repurposed as a drawer liner or organizer tray.

Who It's For

This mat is ideal for homeowners, renters, and anyone who wants a simple, washable layer of protection under sinks and in cabinets where cleaning products, plumbing, or appliances may leak. It suits kitchens, bathrooms, laundry rooms, and utility cabinets where a waterproof liner can prevent staining and moisture damage.

Those who need a heavy industrial tray or a custom-fit liner for nonstandard cabinets should look elsewhere; the mat is flexible silicone rather than rigid containment, and some users reported mixed impressions about material strength, so very heavy or sharp objects placed repeatedly on the mat may reduce its life span.

Pros & Cons

Pros

• Effectively contains spills with a reinforced 0.7 in raised lip to protect cabinet bottoms.
• Easy to clean because the silicone is dishwasher safe and resists stains from common spills.
• BPA free construction and nonslip raised dots help prevent items from sliding around on the mat.
• Versatile 31 x 22 in size fits most standard under sink areas and doubles as a drawer liner or tray.

Cons

• Some customers described the material as less rigid, so it may feel flimsy under very heavy items.
• Fixed size may not be ideal for unusually shallow or narrow cabinets without trimming.
