Tile In Shower Base (Flexing)
I'm looking for some advice.
I'm remodelling a shower. I taken out the old porcelain shower base and am replacing it with a tile-in base.
I applied about a one inch layer of mortar to the floor to level and seat the base.
Here's my question/problem. The plumbing comes up through the floor to connect to the bottom of the shower tray. I think some of the mortar has fallen into the hole in the floor (where the plumbing comes through). What this has created in that the tile-in base will flex about 1/8" in places when you stand on it.
I'm just about to start tiling the base. Will the tile adhesive and the grout strength up the base or will it crack the tile (or grout).
Do I need to, some how, lift the base and re-lay the mortar? Is there any other product I can use to stiffen up the base? If I do need to lift the base is there any advice on how to do this? I scared I'll crack the base.
