SIKADEER Under Sink Waterproof Silicone Mat 31 x 22 in — BPA-Free, Trim-to-Fit Non-Slip Liner

The SIKADEER Waterproof Under Sink Mat is a durable, food-grade silicone cabinet liner that protects under-sink and shelf surfaces from leaks, stains, and slips.

This flexible 31" x 22" silicone tray is made to sit inside kitchen and bathroom cabinets, creating a waterproof barrier and a non-slip surface for bottles, cleaning supplies, and plumbing-prone areas. Constructed from BPA-free, odorless silicone with raised edges and a dual-textured surface, the liner resists oils and heat while remaining easy to wipe or wash. Because it trims easily and comes in multiple sizes, it adapts to most cabinet interiors and helps keep stored items upright and organized.

How does the SIKADEER mat prevent leaks and spills from damaging cabinets?

The mat features a shallow tray design with raised edges that contain drips, pooling, and small leaks so liquid stays on the liner instead of reaching wood shelves or floors. Its flexible edge also allows simple on-the-spot drainage: press the rim near a sink or bucket and direct flow without lifting the entire mat.

• Raised perimeter holds messes and ponding liquids.
• Flexible edge enables quick local drainage.
• Waterproof silicone prevents absorption and staining.

Can I keep the liner clean, and is it durable enough for daily use?

Yes—the smooth, food-grade silicone surface wipes clean with a sponge, rinses under the faucet, and is dishwasher-safe for deeper cleaning. Silicone resists oils, heat, and stains, so it stands up to repeated use by cleaning supplies, soaps, and household items without losing shape or grabbing odors.

• Dishwasher-safe for simple, hygienic cleaning.
• Oil-, heat-, and stain-resistant material preserves appearance.
• Non-porous silicone resists lingering smells.

Will this mat fit my cabinet and work around plumbing or odd shapes?

The SIKADEER liner is sold in multiple sizes and is purposely flexible so you can trim around pipes or corners for a custom fit. If you’re between sizes, the manufacturer recommends choosing the slightly smaller option so the mat sits flat and the edges remain effective at containing spills.

• Trim-to-fit silicone adapts to pipes and irregular interiors.
• Available in 16 sizes to match common cabinet dimensions.
• Pick a smaller size when in doubt for a flat, sealed placement.

How does the textured surface help keep stored items organized?

Both sides of the mat feature complementary textures that add grip for bottles, cleaning containers, and small tools, so items are less likely to tip or slide when doors move or during loading and unloading. The liner doubles as a general shelf protector, drawer liner, or small tray for wet items like cookware or pet bowls.

• Dual-sided texture stabilizes bottles and loose items.
• Works as shelf, drawer, dish-drying, or pet feeding mat.
• Helps maintain tidy, upright storage and quick access to supplies.

Who is this for: The SIKADEER Waterproof Under Sink Mat is designed for homeowners, renters, and anyone who stores cleaning products, plumbing parts, or small appliances inside cabinets and wants a low-maintenance barrier against leaks, spills, and shelf damage. It’s also a practical solution for RVs, vacation homes, and utility spaces where moisture management and easy cleaning matter. Choose the right size, trim if needed, and place the mat under sinks, beneath dishwashers, or on open shelves to extend cabinet life and simplify cleanups.
