12”x12” Peel and Stick Tiles (Redwood City)

I am in search of 12” x 12” peel and stick tiles to cover a 4‘ x 5‘ playhouse floor. Ideally, a waterproof version, used for kitchen or bathroom.

If you have any that you no longer need, I would be grateful to use them!

Photo is just an example, but any style will work.

Thanks!
