A curving wall of glass block and a corner jetted-tub installation are the keys to the layout of this 12 X 9-ft. bath. The tub surround is cleverly extended into the shower, where it forms a triangular seat. A couple of space-saving tricks make the most of the area: The entry to the room is through a pocket door rather than through a standard hinged model; similarly, the doorless shower (sometimes called a "walk-behind" design) frees up valuable floor space in the middle of the room.
