I went in and looked at the problem and thought it would work if they took out the sink and the toilet, then put the shower together in that place, then move the stall over to the base. They looked and thought, and hey yes, that would work.
Now the problem is that they can't take that toilet out until the toilet is installed in the main floor bathroom. And... in order to install that toilet, the walls need to be taped & mudded, and the plumber did not bring his taping tools.
So, they are not coming tomorrow, maybe Monday night.
I want to take a shower!
