I need to do a temporary fix for a sinking toilet. I'm trying to find the right tool to remove a small area of tile, adhesive, and thinset. The layers of flooring are:
- old floor
- 1/4" plywood
- cement board (at least I think it is -- I can't really see it)
- tile adhesive
- 9" square 1/4" ceramic tile
This only needs to last for about 6 months, so my plan is to:
- take out the toilet
- remove the 4 tiles around the waste pipe
- chisel out the cement, thinset, and adhesive
- cover the area with an 18" square piece of plywood
- replace the toilet
My question is: what would you use to chisel out the cement, thinset, and adhesive? I'd rent a demolition hammer, but I'm pretty sure that will wreck more than just 4 tiles worth. I've considered a hammer drill, a rotary hammer, or a chisel and a drilling hammer (i.e. manual), but I'm not sure if those are strong enough.
And, of course, the other (implicit) question is always: is this even a good idea?
