Hello to DIY member, I'm new to the forum.
Want to take old bath tub out and just use the porcelain tile for bottom and all wall for the bath shower, Is it good ideal or not? and if it good to use porcelain tile can you tell me how?
In my opinion, this would not a good idea. You will have a very slippery surface not to mention the maintenance issues for the grout. This will eventually lead to leakage and water damage.
