The eight questions
- 1Which waterproofing system will you use, and does every component come from that manufacturer?
- 2Will the shower be flood tested before tile, and for how long?
- 3Will you photograph the waterproofing before covering it and give me the photographs?
- 4Where will you install blocking, and will it cover a future grab bar?
- 5How will the floor slope be formed and verified?
- 6Where will movement joints go at changes of plane?
- 7What does the written scope exclude?
- 8Who is doing the tile setting, and will the same person be here for the whole job?
The sequence that cannot be compressed
Demolition and rough-in, then substrate and slope, then waterproofing, then a flood test, then tile, then grout cure, then glass measured to the finished tile. The flood test and the grout cure are chemistry and physics, not scheduling preferences. A programme that skips them is not faster; it is just less certain.
