IT will be a one color simple tile, standard height on the wall

U have to many open end question to give a good estimate on materials.

Do walls have to be redo with concrete board?

Is there a return at entrance or is door full front size?

Do u have to buy the tools?

Tile start at about $1.30 a square foot and go up from there. This does not include tools, adhesive, cap tile, wonder board, Insulation( if needed),vapor barrier, screws for wonder board, soap trays or grout.

This will give u an idea of things that are needed.

We would be better to also know the actual square footage of the walls since we have no idea if you are going to the ceiling or not.
