Do I need to tile under or behind the unit?

It is recommended that you fully tile under your shower, steam shower or whirlpool bath, this is because they are designed to be freestanding and as such may be required to be slid away from the wall for service access. Tiling fully under the tub enables you to slide the shower/whirlpool with ease. Tiling behind your shower is optional as the glass at the rear of the cabin is not transparent. We would recommend that you only need to tile one or two rows of tile behind the edges to ensure a tidy finish.
