URMONA 34" x 22" Waterproof Silicone Mat for Under Sink Storage, Kitchen & Bathroom

What it is and why people buy it

The URMONA 34" x 22" Waterproof Silicone Mat is a flexible silicone under-sink liner designed to protect cabinets from the annoying stuff that happens over time: drips, spills, and everyday messes. It’s the kind of mat you slide under a sink cabinet to create a water-and-oil resistant barrier, so cleanup is easier and cabinet surfaces are less likely to get stained or damaged.

On paper, it’s built for real life—silicone that’s described as durable, water- and oil-resistant, and easy to wipe down after a leak or spill. The double-thickness design is also meant to be flexible enough to fold or roll so you can reach tight spaces when installing it.

The everyday benefits you’ll notice

Where this mat tends to earn its keep is in “small events” that add up: a slow leak you catch late, a container that tips, or cleaning products that leave marks. With an under-sink mat, you’re not just protecting the bottom panel—you’re also buying yourself less stress when something goes wrong.

It also uses raised/ridged styling (the description mentions a relief design) to help with drainage and to cushion items if you use it for storage or as a protective surface. That matters if you place things on top of it—like cleaning supplies in the cabinet or a pet-related pad inside a storage area.

A practical example: imagine you’re reorganizing your under-sink cabinet. You line the base with this mat, put spray bottles and sponges back, then notice it’s easier to keep surfaces clean because any drip or splatter doesn’t soak directly into the cabinet bottom. When you wipe it later, you’re cleaning silicone, not damaged wood.

Key points to consider before buying

This is where you want to be a little careful. The mat is meant to cover the area under the sink, but the description specifically notes to check whether the water pipe runs through the base of the cabinet before purchasing. If your plumbing layout makes that area unusually obstructed, you may need a different size or plan your placement accordingly.

Also, the listing says the under-sink protector comes in multiple sizes (and colors), but you’re viewing the 34" x 22" version. If your cabinet is smaller—or if you’re buying for a narrower bathroom vanity—you could end up with extra material that’s hard to fit neatly.

Finally, it’s flexible and designed to be foldable for storage and installation. That’s convenient, but it also means you’ll want to position it so it lies flat where you expect spills to land.

Where it works best (and where it may fall short)

URMONA positions this as multi-purpose: under-sink cabinet liner, kitchen and bathroom protection, and even a pet food pad or surface for pet-related use. It can also act as a liner for shelving or storage areas, and the relief/drainage concept is described as useful beyond just leak protection.

If your goal is straightforward—protecting cabinet bottoms in kitchens, bathrooms, or utility rooms—this mat fits the bill. It’s not trying to be a high-tech solution, it’s a practical barrier you can clean.

Where it may not be the best match is if you need something for a very specific fit or a fully custom shape around complex plumbing. The product can be flexible, but it’s still a rectangular liner, so awkward cabinet geometry may require extra work to make it look and function right.

Mini FAQ

How easy is it to clean after a spill?

The mat is described as water- and oil-resistant, which is meant to make cleanup easier when drips or spills happen. Wiping it down is the intended use.

Does it help protect against leaks and scratches?

Yes—according to the description, it helps protect cabinets from leaks, spills/stains, chemical splashes, and scratches.

Can it be used for pet food?

The listing says it can be used as a pet food pad for dogs and cats, so it’s not limited to under-sink storage.

Is it only for kitchens?

No. It’s presented as suitable for kitchens, bathrooms, and service rooms, and it can also function as liners for other storage surfaces.

Should I measure my cabinet before buying?

You should, especially because the description advises checking the plumbing route (whether the water pipe runs through the base). Measuring and planning placement will prevent a frustrating fit issue.

Final verdict

It’s a solid buy if you want a flexible, waterproof silicone under-sink liner that helps protect cabinet bottoms from leaks, spills, staining, and scratches—and you like the idea of simplifying cleanup with a wipeable surface. It’s also a reasonable multi-use option if you can benefit from a waterproof, easy-to-handle mat for storage or pet-related use.

You may want to skip it if your cabinet layout makes the base difficult to cover around the plumbing, or if the 34" x 22" size doesn’t match your available floor space under the sink. In that case, the “multiple sizes” approach matters more than the material itself.
