Under Sink Mat 34 x 22 in Waterproof Silicone - Raised Lip Protector

Our review of this 34 x 22 in under sink mat finds it best for homeowners who want a low-maintenance barrier against leaks and spills. The mat is constructed from 100% waterproof silicone and is dishwasher safe, which makes cleanup simple after a messy plumbing incident or a spilled bottle under the sink. It is designed to stay flat and grip cabinet bases, and the reinforced 0.7 in raised lip contains liquid on the mat surface instead of letting it run into the cabinet floor. For anyone fitting a standard double-sink cabinet, this size offers wide coverage with minimal trimming.

Key Features

• 100% Waterproof: The silicone construction creates a true barrier between liquid mess and cabinet surfaces to protect wood and particleboard from damage.
• Dishwasher Safe: The mat can be cleaned in the dishwasher for a thorough rinse after spills, making routine maintenance quick and hygienic.
• BPA Free and Stain Resistant: Made from BPA free silicone that resists staining from common liquids so the mat keeps a neutral appearance over time.
• Reinforced Raised Lip: The 0.7 in raised lip is reinforced with added strips to help the edge keep its structure and limit tearing when containing leaks.
• Non-Slip Surface: Raised silicone dots on the top help prevent items from sliding around, so bottles and cleaning supplies stay put during daily use.
• Versatile Use: Sized at 34 x 22 in for standard cabinets, the mat also works in bathrooms, laundry areas, or as a protective shelf liner for aquariums and trays.

Who It's For

This mat is ideal for homeowners or renters who want to protect under-sink cabinet floors from occasional leaks, drips, or cleaning-product spills without the hassle of constant cleanup; the waterproof silicone and dishwasher-safe design suit busy kitchens and bathrooms. It is particularly useful under double sinks or wider cabinets where coverage matters and trimming is not desired.

Those who need a firmer, thicker rubberized tray or a custom-fitted rigid pan for heavy standing water or major leaks should look elsewhere; while this silicone mat is waterproof and reinforced at the lip, customers have reported mixed impressions of material sturdiness, with some finding it less rigid than expected.
