To achieve the look you will need:
Airstone Tiles and Airstone adhesive, a 29 oz. caulk gun, a hack saw, some bath caulk (choose a shade that matches your tub color) and a putty knife.
Note! When choosing the tiles read carefully what you are buying so that you don’t end up with different type of tiles and not what you need. As for the adhesive, since the bathroom is a high moisture area, it’s best to use adhesive suitable for outdoor spaces.
