So far, I have bought a recipricating saw, a circular saw, a cordless drill, a drill with a cord, a pipe wrench, a chain wrench, about $120 worth of hole saws (that's 2 saws and an arbor, by the way), a Rotozip-type tool (Harbor Freight), and assorted bits and pieces of stuff.
The demolition is finally finished, and we have started with replumbing (more than once, as plans have changed). The hot water supply lines are all run, but turned off, and the cold water has one more connection for the shower that I'll make tomorrow or Monday.
The pieces of plywood for the floor have been cut and laid in place, but not screwed down, since we still need to do the drain lines for everything. I laid the shower floor in place and discovered that it came too close to the toilet, so the shower got moved to the other side of the bathroom and we are back to putting a small pedestal sink in next to the toilet.
Also, reading the instructions for the shower (always a good idea), I discovered that we need to put the sheetrock in first! So, we will start insulating and doing sheetrock work later this week, and then get the shower set.
I keep finding out that I have to do a bit on this part, then a bit on that part, so that the whole project is knitted together: I can't screw down the floor till I finish the plumbing, which I can't do till I have the shower in place, which I can't do until the sheetrock is in place, which I can't do until the floor is screwed down!
Good thing it's a small bathroom!
