line your cabinet under the kitchen sink with peel and stick tile. Easy to wipe and helps cover already damaged cabinet bottom or helps to protect a new cabinet. I'm going to do this...one of my summer projects. :)
Holy crap, this is fabulous! You can also do this behind the mirror over your sink and use piano hinges to hold the mirror, no one will know you have additional storage! Just build shelves between the joist in the wall and finish it off with wall board and there you have it!
