I am seriously considering vinyl tiling my bathroom walls. I am sick and tired of trying to scrub off toothpaste and soap that got splashed from MY KIDS off the walls!!! I think the easiest thing and most cost effective for me would be to use vinyl floor tiling. I have actually seen it done before and it looks great. I know at Family Dollar you can buy 30 tiles in a box for just $11.00. My bathroom is so small that I imagine two boxes would do it.
Then, when my kids are older I can move on to the more expensive permanent stuff lol. I'd hate to put out a lot of money on anything right now because nothing lasts here. Between my three kids and the five or six more that I seem to have hanging around all the time there just isn't any hope for buying the really nice expensive stuff lol!
