I used cheap peel and stick vinyl tiles.

I spent a bit more but SOOOOOO WORTH IT.. VINAL FLOORING for the local home improvement store: comes on the HUGE ROLL they will cut you what every amount you want..I had them cut small strips the depth of the cabinets so I only had to cut into chunks I needed..Since it DURABLE, EASY TO CLEAN, and REMOVEABLE with no tacky reside of any kind.. I used a felt pen, box cutter, and did in on the garage floor..I also did all the vanity drawers and under

sink areas too..

I forgot to mention,,,,, with the vinal flooring you don't need to glue .. By nature its designed to lie flat....I will never deal with any of the other stuff again..EASIER and more durable
