Under Cabinet Waterproofing Using Peel-&-Stick Tiles

Under Cabinet waterproofing with peel and stick tiles

I titled this post as Under Cabinet Waterproofing, but I realize that when water wants to destroy something, there is little we mere humans can do to stand in its way.  But with that in mind, I recently saw a pin on Pinterest showing someone who used peel-and-stick vinyl tiles to help prevent water damage under the sink.  So the next time I was wandering through my favorite orange store and saw some discontinued vinyl tiles on super sale, I thought I’d try it.


It ended up being very easy. I’d say it took half an hour including making cuts for the waterlines. A few tools was all it took.

Under Cabinet Waterproofing Materials & Tools:

  • Peel-and-stick tiles
  • Box cutter
  • Scrap wood or cutting board
  • Something to protect the floor around you. I used an old rug. (Optional but highly suggested)
  • Drill with paddle bit (1″+ depending on size of waterlines) (Optional but easier than cutting little circles with a box cutter)
  • Square (optional)
  • Latex caulk for additional under cabinet waterproofing

I suggest cutting the tiles on a scrap piece of wood so the box cutter doesn’t damage whatever you are cutting on. I also found an old rug came in handy as added floor protection since I did all the work right on my kitchen floor in front of the sink. I used the drill to make holes for the waterlines, again using the old board to drill against. Of course I couldn’t slip the tiles over the water lines, but luckily these tiles are very malleable, so I simply made a straight cut from the edge of the tile to the hole and worked the pipe through the cut into the hole. This hole does create a place where water could damage the cabinet, but adding some latex caulk and also caulking around the escutcheon can prevent this from happening.


The square came in handy as a straight edge to cut the excess amount off the sides of the tiles.

I know that if a lot of water goes through the seams it can still cause damage, but I’m hopeful these tiles will help prevent water damage from those random little drips that seem to happen every once in a while under the kitchen sink. I may add a small bead of latex caulk around the edges of the cabinet and perhaps a tiny bit between the tiles to add just a little bit more under cabinet waterproofing. I haven’t done this yet, but I think it could be a good preventative step.

Since it was so easy, I’m now thinking of adding this under cabinet waterproofing to bathroom sinks as well.

Total cost:  Somewhere between $3 and $5.

  • Looks great! In the meantime, I’ll just keep a bucket under the trap. And I do have an electrical question: how hard is it to change out an old ceiling light fixture? S’s bedroom lights burned out and when I went to replace the bulbs, one of the bulbs came out of the metal end piece. Then the ceramic piece light bulb holder piece broke off when I tried to get the metal end piece out with some pliers. So now I need to replace S’s light sometime but she’s using a lamp in the meantime.
