My contractor is installing a 3/16" plywood as a shower pan subfloor on 16" floor joists. It is for a curb-less shower. I think they did that because they built the floor too low to allow water drainage and now has to
- Cut into the joists for the slope
- Use 3/16" plywood as subfloor (44" x 76")
I am very concern about the integrity this flooring. My questions are:
- Is this safe?
- What are the potential problems?
- How long can it really last? It's newly built and seems OK now but over time moisture could erode underneath things can fall off. It just looks very fragile.
- What would the fix be?
