Hi,

I am planning on replacing an existing bath tub but would like opinions on whether to go with a tile or a plastic surround. Being on a 2nd floor condo, my main concern is waterproofing. In either scenario, does a water proof membrane need to be applied to the walls? I am planning on going with Hardibacker CBU up to at least 72."

If you could include a simple how-to (steps) for running a liner up for tile, that would be very helpful (e.g., go with a weephole drain, pre-slope under tub? (some say to use a level base), how far up the wall should the liner go? I noticed some say to go just above the water line but then what about all the water that gets behind the tile at 5 feet? I noticed that the Kerdi system goes all the way up the wall. All the walls are interior and not exterior.

Thanks!
