CANIVI Silicone Under-Sink Mat, 34 x 22 Inch Waterproof Blue-Grey Cabinet Tray with Raised Walls

A flexible silicone tray that lies flat on the base of a sink cupboard, catching drips from a weeping trap, spilled cleaning liquid or a slow supply line before any of it soaks into the board underneath. Walls rise and angle inward, so liquid pools toward the middle rather than creeping over an edge.

• Size: 34 by 22 inches, with walls 0.79 inches high. Weighs 2.1 lb.
• Intended cupboard: a 36 inch wide unit, with 22 inches taken as internal depth.
• Surface: textured rather than glassy, which stops bottles sliding when the sheet is drawn forward.
• Care: a wet cloth clears most spills, and the sheet is soft enough to roll up and rinse.
• Other uses: beneath a pet bowl, under a plant pot, as a draining surface beside the sink, or as a work sheet for messy hobbies.

The 3.3 gallon capacity claim does not survive arithmetic. A 34 by 22 inch pan walled to 0.79 inches holds roughly 2.5 gallons brimmed level with the rim, and no real spill fills a tray to its lip. Two gallons is a fairer practical limit, and the larger figure should be read as the manufacturer speaking.

Two colour names are in play - the attribute sheet says blue grey while the product name says grey. Expect a grey carrying a blue cast.

Check where plumbing enters through the cupboard floor before ordering, since a pipe rising through the middle will mean trimming.
