GORILLA GRIP LeakGuard Non-Adhesive Under Sink Mat for Kitchen Cabinet, Waterproof Quick Dry Shelf Liner, Durable Absorbent Felt Mats for Bathroom Sinks, Cabinets, Dresser, Easy to Trim, 24x30 Black

Finally tackled the peeling stain and grime beneath our rental’s sink—prompted in part by past U-trap leaks. This liner has been a solid upgrade, delivering both peace of mind and solid performance.Key Strengths:- Durability: The synthetic felt and backing show no signs of fraying. Confident this will hold up for at least 2–3 years. Has not wrinkled after 3 months.- Water Protection: The impermeable layer effectively blocks leaks from seeping through. While it dries slowly, it does prevent subfloor moisture damage.- Cut-to-Fit: Easy to trim with a box cutter or textile shears. A printed grid would help with precise fitting but isn’t essential.Limitations:- Best for enclosed areas—this isn’t designed for aesthetics, so avoid using it in visible or high-traffic zones (though it could honestly be a trunk liner if large enough). Use as a shelf liner is excellent.- While it handles occasional leaks well, long-term exposure to standing water may test its limits. I won't experience that, but worth considering.Verdict:A reliable, cost-effective solution for safeguarding cabinets. Not flashy, but highly functional—worth it if you want to keep moisture and mold at bay.

This fulfilled my need for a protective mat under my kitchen sink. It seems durable, looks nice, and was easy to trim to fit. Quite happy with it.

Does the job. That area under the sink was really pretty gross. This liner transforms the space into something that looks organized and clean. I'm not going to live down there, but I no longer dread having to go searching for cleaning supplies. Relatively easy to cut. Still not sure what this liner has to do with gorillas.

Fits and looks great in my laundry cabinet. Looks like it will be easy to clean.

Was easy to install and strong/

This product has saved me a lot of work and mess 3 different times when my kitchen sink developed a leak, the last time when I was trying to dye a garment. It holds an amazing amount of water, I think several galllons. They give you time to clean up the mess before it gets all over the floor or ruins your cabinets. If it is only water, then you can remove them and let them dry then re-install. The mats are easy to cut with regular scissors. Many colors available to match any decor.

Love this product. Easy to cut to size and so far it works great keeping my cleaning product drips from damaging the cabinet

I love the clean look of these liners in my bathroom sink cabinets. This liner is a sturdy weight, stays in place, and is very easy to cut to size. I purchased one and liked the result so much I purchased the largest size and then cut out for multiple cabinets to save $$. My under sink cabinets look amazing!
