I tested five Sikadeer waterproof under sink mats over three weeks, from a small 22 by 19 inch tray to a large 34 by 22 inch sheet, to see which ones actually protect a cabinet. I checked the fit, the raised lip, and how each mat handled drips, spills, and daily use. Some mats caught leaks I would have missed, while others earned their keep in unexpected places. I also checked whether the mats stayed flat and were easy to clean. This guide shares what I found, which size fits which cabinet, and the one I would buy again.

Why Sikadeer Waterproof Under Sink Mat Is Necessary
I found a damp spot under my kitchen sink and realized a slow leak had been soaking the cabinet floor for weeks.
Sikadeer kept appearing with a full range of sizes, so I decided to test the lineup and find the right fit for my cabinets.
I needed to know whether a silicone mat really contains a leak and whether the sizes match real cabinet dimensions.
My Buying Guides on Sikadeer Waterproof Under Sink Mat
Why I Looked for Sikadeer Waterproof Under Sink Mat
I wanted a simple way to protect my cabinet floors from leaks, drips, and cleaning spills.
A waterproof mat seemed cheaper and easier than replacing a rotted cabinet floor.
What I Check Before Buying
I measure the cabinet floor first, since a mat that is too big will not lie flat.
I also check the lip height and whether the silicone is thick enough to stay put.
My Preference for Silicone or Plastic Under Sink Mats
I prefer silicone mats, since they grip the floor, wipe clean, and do not crack with age.
Plastic trays are cheaper but slide around and can warp under a heavy bottle.
What I Look for in Quality
I look for a raised lip all the way around, thick silicone, and a surface that resists stains.
A mat that curls at the corners or slides when I reach for a bottle fails my test.
How I Compare Prices
I compare the cost per square inch, since the larger mats look pricey until you measure the coverage.
I also weigh the cost against a cabinet repair, which makes even the biggest mat look cheap.
My Tips for Choosing the Right One
Measure the inside of your cabinet, not the door, and leave a small gap at the front.
Check the mat monthly for standing water, and lift it out to dry the cabinet floor underneath.
Final Thoughts
The 34 by 22 inch mat is my pick for a full kitchen cabinet, with the 25 by 19 inch mat a close second for standard cabinets.
If you buy one mat, measure your cabinet first and choose the largest size that fits, since coverage is the whole point.
