It's very different, isn't it? We removed the awful yellow tub and placed a brand new pedestal sink in the same location. We also completed re-tiled the entire bathroom. It's hard to tell color, but it's a dark green, in the same style as the other bathroom.
We removed the closet and tiny wall sink and had a custom shower stall put in. We hired contractors to do most of the carpentry and plumbing work, but we did all of the tile ourselves. It was over 100 square feet of tile in that little bathroom! We tiled the walls of the shower all the way to the ceiling.
Because of the location of the window above the tub, the previous owners had actually covered the window! We uncovered the window, restored it, and frosted the panes for some privacy (we still need to paint the trim). The window is the old double hung type. We had to remove the sashes, sand down several layers of paint, and replace the ropes. But, they're now fully functioning windows.
Now for some in progress pictures:
Talk about getting down to the studs, we actually removed the entire floor!
