Hi,
We recently had a tiler raise an existing shower floor to turn it into a walk-in disabled shower. Unfortunately they stuffed up the fall levels and the water runs out the side and they need to do it again. However we have also since wondered about whether the shower needed to be re-waterproofed. The previously existing shower floor likely had waterproofing and didn't have issues, and he just did a bedding over the top and lay the tiles without any new waterproofing. Will this be fine, or should there have been a new layer of waterproofing? Thanks for any advice.
