Under Sink Mat 34”x22” — Trimmable Waterproof Silicone Cabinet Liner with Raised Edges, Grey

One mat, eight possible sizes — cut it to fit whatever cabinet you have.

Under-sink cabinets vary more than you’d think — 30”, 28”, 34”, different depths. This 34”x22” silicone mat starts at full size and trims down to fit eight common cabinet sizes, including around pipes and corners, without any special tools. Set it flat, raise the edges, and your cabinet floor is protected from drips, cleaning product spills, and slow leaks.

Why It Works

• 34”x22” Trimmable Size — Trims to fit 8 cabinet sizes: 30”x22”, 30”x20”, 30”x15”, 34”x20”, 28”x22”, 28”x20”, 28”x15”, and original 34”x22”
• Raised Edges — Perimeter walls contain liquid and prevent runoff to cabinet sides and back
• Waterproof Silicone — Flexible, food-safe silicone that holds spills without absorbing moisture
• Non-Deformable — Soft but shape-retaining material stays flat without curling or bunching
• Easy to Clean — Rinse with water or wipe down; no machine washing needed
• Multi-Use — Works for cleaning supplies, pet items, and general under-sink storage organization

Best For

Kitchen and bathroom cabinets with active plumbing, households with irregular cabinet sizes that standard mats don’t fit, renters protecting cabinet floors, and anyone looking to organize under-sink storage at the same time.

How to Use

1. Measure your cabinet interior to confirm which of the 8 sizes fits best
2. Trim along the raised edge with scissors if needed
3. Place flat in the cabinet, edges facing up
4. Rinse or wipe clean monthly or after any visible drip

Important

Designed for minor drip and spill containment — not a substitute for plumbing repair. Address any active leak at the source promptly.
