Standing in Mud? - Part 1

Yes, but it is a type of masonry mud known as floor leveler that levels a floor with assistance from gravity before hardening. This is one of the steps in a major remodel of my son's bathroom. The following photos and those in follow-up posts (5/21/19 Part 2 and 6/8/19 Part 3) show major events in the project.

The was the bathroom with its 1939 tube and arch, It was remodeled in 1999 - new wall and floor tile, new tub surround, new fixtures. Unfortunately, it was not a quality job - 60% of the floor tile had cracked, the tub surround has separating from the wall, the tub which had been resurfaced was pealing,....

Demolition.... We took the cast iron tub out in one piece. It took 4 to carry it down the stairs.

The back wall was insulated, and the 1x8" rough sawed oak sub-floor removed.

The floor had settled in the last 80 years, about 1 1/2" from left to right. 2x4s were screwed to the old joint to level the floor and cross supports added. The old 1 1/5" galvanized drain pipe (right side) was Roto Rooted and a 2" PVC extension was run to the center of the area.

The shower alcove was framed as per the 48" shower unit's specs. The left/exterior wall was insulated (not visible).

The shower water control was fabricated (soldered Cu pipe with shark-bite connections to the original water lines), positioned, anchored and braced.

The shower based was put in place and the drain connected. The old tile floor was removed in the rest of the bathroom exposing a oak floor which was solid but uneven and had settled. Hardie board was glued and screwed down into the subfloor.

The shower unit side walls were put in place and hardie board seams and screw holes finished with thin-set mortar. The pink is a 1 1/2" high dike built around the perimeter from styrofoam and caulked (white) to prevent leaks.
