The more expensive vinyl floors and tiles have better resistance to staining, scratches, gouges, etc. Not only is the performance better but so is the the warranty on the high-end vinyl floors. Also, as you go up in quality you will also notice improved styling and more textural reality in these floors.
Vinyl tiles are ideal for the do-it-yourself projects in kitchens, bathrooms, and more. They come in both self-stick tiles (adhesive applied at factory) or dry back tiles for glue-down. Vinyl tiles range from 1/16" thick up to 1/8" thick. Sheet vinyl can be a little trickier to install for the do-it-yourself person. For information about installing a vinyl floor you should always refer to the manufacturer's written documents.
