I was a bit curious.

I've been spending nearly all of the last 80 weekends doing all of the little things on my apartment (~1880). Mostly related to the bathroom, which was added about 100 years later. At this point, the only part left to do is pay someone VVS qualified to replace the floor drain, remove the plastic floor and re-tile everything. Or, do I (easily) remove the walls and make the floorplan make more modern sense...

My oiled oak herringbone floors show some character and sound like death, but nobody lives downstairs, so I'm not about to sand them down for the umpteenth time in 130 years.
