Annex 84

As I wrote last week, there are quite a few steps to transforming an open space into a functional shower!  After the OSB was attached to the frame, the spaces between the floorboards had to be caulked and sealed with duct tape, not to prevent water from leaking out (the heavy vinyl shower liner you can see in the second picture does that), but rather to prevent insects from coming up from beneath and possibly damaging the liner.  Then because concrete (including cementboard) is porous , we had to install a layer of tar paper to prevent moisture from seeping through, becoming trapped against the wood, and rotting it; this is also why the shower liner is necessary.  It went in next, followed by the tar paper (which you really can’t see in either picture, but it’s not really much to see), followed by the cement board.  We’ve already run the supply-side plumbing using pex pipe; the easiest way to supply water to the new bathroom (and the new water heater) was to drill through the wall into the existing bathroom, one hole for cold coming out and one for hot going back in (because the new heater will supply both bathrooms).  You can see the holes in the upper picture; Grace supervised from inside while I drilled from outside, going slowly as per her instructions just in case there were pipes or electrical wires inside the wall.  As it turned out, she needn’t have been concerned; as I drilled deeper and deeper, I realized that there was no cavity in the wall; it is constructed of solid cedar beams six inches thick!  Although the methods the first owners of my house used to build it were often quite unconventional, and there’s nothing in it that’s perfectly plumb, level, or square, one thing it is not is flimsy!  Many of the walls are of solid hardwood, as are many of the floors, and as I’ve built onto it I’ve learned to trust its sturdiness even if I have to scratch my head at some of its oddities.
