Our 1925 Craftsman had a number of unique features, some of which we preserved, and some which had to go. The Master Bathroom was one that had to be completely renovated, down to the studs. It was such an odd space before. It was essentially a Jack-and-Jill bathroom, but the pass-through from one side to the other was the shower! I've never seen anything like it, nor had our contractor.
The room had a nice-sized footprint, but it was broken up into two tiny powder rooms (with 2 separate small vanities and toilets), then a large (and ugly) tiled shower in between. No tub, and just one small window, which let in very little natural light.
