Famous Dino Silicone Under Sink Mat — 34" x 22" Trimmable Waterproof Liner with Raised Lip, BPA-Free

The Famous Dino Original Under Sink Mat is a trimmable, waterproof silicone liner that protects cabinets by catching leaks, spills, and debris while remaining easy to cut, clean, and position around pipes.

Under-sink areas are prone to hidden leaks, chemical spills, and pet messes that ruin cabinet floors over time. This 34" x 22" silicone mat from Famous Dino is built to sit flat under sinks, form a raised lip to contain liquids, and be trimmed to fit common cabinet widths and depths. Made from BPA-free silicone, it’s flexible enough to wrap around plumbing yet durable enough to hold up to 1.5 gallons of water, giving you extra time to notice and fix problems.

How does this mat stop leaks and spills from damaging cabinets?

The mat’s continuous raised edge creates a shallow drip tray that keeps water and cleaning solutions from seeping into wood or particleboard. Its flexible silicone body lies flat against cabinet floors and resists warping, so water pools on the mat instead of spreading beneath it.

• Raised lip edge holds liquids and prevents overflow onto cabinet surfaces.
• Holds up to approximately 1.5 gallons for temporary containment.
• BPA-free silicone resists stains and chemical damage from common household cleaners.
• Flexible material conforms to pipes and uneven cabinet floors for full coverage.

Can I trim the mat to fit my cabinet and around pipes?

Yes — the Famous Dino mat is designed to be trimmed with scissors or a utility knife so it fits a wide range of cabinet sizes. Its pliable silicone cuts cleanly, and because the material flexes, you can shape it to move around plumbing without needing a seal or adhesive.

• Standard size 34" x 22" trims down to fit 36", 31", or 28" cabinets as needed.
• Depth can be reduced to match shallower cabinets while retaining the raised lip.
• Easy to cut around pipes and fixtures; no specialty tools required.
• Lays flat after trimming and won’t warp like rigid trays.

How do I clean and maintain the silicone sink liner?

Maintenance is simple: wipe the mat with a damp cloth for light messes or remove it and rinse with soap and water for a deeper clean. Silicone resists staining and absorbs no odors, so it stays hygienic with minimal effort.

• Quick surface wipe for everyday dirt and splashes.
• Removable for sink-side washing or hose rinsing when needed.
• Nonporous silicone resists bacteria and odor buildup compared with fabric liners.
• Durable material retains shape after repeated cleaning cycles.

What else can this mat be used for besides protecting cabinets?

Beyond under-sink protection, the mat works well as a pet feeding pad, a dish-drip surface, a craft or utility mat, and even a temporary shoe-disinfection area thanks to its raised edges and waterproof surface. Its large coverage and easy-to-clean material make it a versatile household protector.

• Pet food and water mat that keeps spills contained and floors dry.
• Under small appliances or dish racks to catch drips and crumbs.
• Work surface for messy hobbies, plant pot trays, or clean-up stations.
• Portable disinfection surface for shoes, boots, or gear when needed.

Who is this mat for? Homeowners, renters, and pet owners who want straightforward, reliable protection for under-sink cabinet floors will benefit most. It’s especially useful for anyone with older plumbing, frequent cleaning-product use, or children and pets in the home — plus DIYers who prefer to trim and fit their own liners without tools. If you want a low-maintenance, long-lasting liner that contains spills and simplifies cleanup, this Famous Dino silicone under-sink mat is a practical choice.
