WINISOK 40×22 Under-Sink Mat vs Gorilla Grip 22×40: Measure Before You Buy

An under-sink mat is a practical cabinet accessory, provided it fits the actual floor inside the cupboard. The dark-gray WINISOK 40×22-inch mat and gray Gorilla Grip 22×40-inch mat have the same nominal footprint when rotated. Their raised edges make them worth comparing, but neither should be treated as plumbing insurance or a substitute for checking a leak.

Our editorial standard →
The cabinet opening is not the usable floor

Measure inside the cabinet rather than using the width printed on a kitchen plan. Hinges, frame lips, center supports, disposal fittings and pipes can reduce the clear space. Make a paper template if the floor is awkward, then check whether you can slide that shape through the door opening. A flexible mat may pass through an opening that a rigid tray cannot, but it still needs to lie as intended once installed. If a pipe passes through the cabinet floor, decide whether cutting around it would defeat the containment benefit you wanted.

Think about the spills you want to catch

A small detergent drip and a persistent plumbing leak are different problems. A raised rim can help keep a minor spill on the mat, yet a leak can continue after any tray reaches capacity. We would use the mat as a surface-protection and cleanup aid, while keeping access to shutoff valves clear. Do not rely on an unverified gallon-capacity claim to leave a known problem unattended. Consider the items you store as well: tall bottles need a stable position, and a mat that bunches beneath them may create its own nuisance.

Compare the selected sizes, not the starting prices

Gorilla Grip offers several dimensions under one listing. The smallest option's price is not a fair comparison with a forty-inch mat. Our selected variant is explicitly gray, twenty-two by forty inches. When comparing offers, confirm the cart still shows that size and inspect whether its corners suit your cabinet. Cleaning access matters too. The useful question is how easily you can remove everything, lift the mat and inspect the cabinet beneath it. Texture or extra rim reinforcement may be worthwhile, but neither proves one mat will contain every spill better without a controlled test.

One last fit check

Leave a clear path to the plumbing shutoff after installation. The mat should make inspection easier rather than encourage packing the cupboard more tightly. An occasional look beneath stored bottles remains useful even when the cabinet floor is covered.

  • Same nominal footprint allows a fair fit comparison
  • Raised dots help separate stored items from the base

  • Texture and corners still need periodic cleaning

THE SHOPFEST DECISION

What we would choose—and why.

Buy whichever exact size lies flat around your cabinet's obstacles at the better delivered price. Gorilla Grip is the documented alternative if you value its rim and surface details. Skip both if installation would require cutting away most of the containment edge.
