We are having to redo the shower and have to keep the brown tile that’s around the bathtub.
Long story short, a family member owns the house and is funding the project (so there’s no way around the keeping the brown tile on the tub), but I can pick out the materials for the shower/walls.

How would you work with this?
What size/color tile do you recommend for the shower?

I was thinking that whatever goes on the shower walls should extend across that entire back wall.

Thanks so much!
