Old baths often have odd bumpouts or off-center placement of windows, doors, and fixtures.
If you like such quirks, stick with them. Otherwise, small shifts can create a more symmetrical, functional space without diminishing the room's charms.
In this master bath, designer Steven Jones specified that the top of the window casing, door casing, and medicine cabinets should all align at a height of 7 feet. "In a small room, every irregularity becomes pronounced," he says.
If your bath has too many entries, you may be able to close up a doorway and create space for another fixture or built-in storage.
Bathrooms in old houses rarely included two sinks, but rearranging fixtures may allow you to double up.
