How do I remove a small concrete shower pan lip without losing my sanity in the process? Special snowflake details inside.
Mr. Muirne81 and I are renovating a 70+ year old utility shower in the basement. The original pan is made of a super-hard concrete. We gutted the stall and waterproofed everything, then installed concrete board to the studs, anticipating that we would just tile up and over the pan edge that juts out from the base of the wall
. (A small expansion gap was left between the board + the pan.)
Unfortunately we were naive, and didn't think about the fact that this edge only exists on three of the walls, nor the fact that the edge is uneven. In some places, it only extends 1/2" from the base of the concrete board. (Face palm)
Because the pan extends completely behind the depth of the concrete board, it was decided to chisel just the protruding portion flush with the concrete board so that floor tile & wall tile could be installed more easily. Great theory, but in reality, it's taking me forever to chisel the edge. (Only 4" in an hour. Yikes.)
Does anyone have any ideas for speeding up the process? Is there a concrete saw that's small enough to be used in a tight shower stall? Would a reciprocating saw w/masonry blade be able to chew through the concrete? I know the fastest way to solve the problem would be to hire a pro, but as much as we'd like to, it's just not something we can afford at this time.
Thanks in advance for your thoughts!
