Working within the constraints of a small space always is a challenge. It’s even more so when that space is inside a historic structure. Such was the case for the bathroom of this 1919 craftsman home located in the historic district of Spaulding Square in West Hollywood, Calif. It had been a mere 15 years since the room was renovated with a Mediterranean look, but the homeowner wanted to restore a more traditional style so it existed more cohesively with the rest of the recently remodeled home.

To achieve this, Lindsay Chambers had to meet the client’s request for a spa-like ambiance without making any changes to the room’s existing size or space, leaving the walls and windows in their original locations. What made the task even more daunting was the homeowner’s desire to have both a shower and a tub in the 100-square-foot area. “Because it was so tight, we decided for two reasons to go with a zero-entry shower,” Chambers explains. “One, it allows them to age in place because of the universal design element, and two, it makes the shower feel big, light, and airy. We also were able to fit in a freestanding tub without it feeling too crunched for space.”

A floating glass wall used in conjunction with the open-entry rain shower, as well as the white and light gray color scheme of the Cararra marble used throughout, solidified the modern design without imposing on the architectural integrity.
