As everyone probably already knows, every little chore is an ordeal.
First ordeal accomplished — I have taken everything out of the master bathroom except the few pieces of cement board that must still be installed.
The space from the shower to the end wall where the double sink vanity will sit is about 6′-11″ with 6′-6″ allotted for the length of the vanity.
A short explanation of the plan below focusing on the master bathroom. There is a door between the bedroom hall and the bathroom but no door between the bathroom hall (at the end of which is a linen closet) and the bathroom proper. I think the tile should stop at the opening without the door so the entire hall way has continuity of flooring which in this case will be wood.
First order of business make the subfloor flush with the shower pan.
What ordeal are you working on?
