Do it yourself

I can't speak to whether stick-on tile or sheet vinyl is easier to apply, since our handyman did ours. However, regarding price, and since you are doing a relatively small space, remember that you may be able to get a deal on sheet vinyl in the "remnants" section of your local flooring store. (It has been my experience that the smaller mom-n-pop stores are more likely to have a remnant section than the big box stores.) When we did our bathroom, I found a very nice leftover piece of high-grade sheet vinyl that was the perfect size for our small bathroom ... and it cost me 15 bucks. (Oh, plus tax.) No kidding! Ann
