After: To make the most of the space, the firm used a partial wet-room layout. This meant placing both the shower and tub within an enclosure. The enclosure has two glass panels with a door in the center. This allows the entire bathroom to enjoy the natural light from the wet room’s window.

“We wanted to elevate the space as much as possible with elements like a freestanding bathtub and a large vanity,” Fishman says. Looking into the shower, a striking marble-covered wall steals the spotlight. The marble also provides an elegant backdrop when the homeowners are looking in the vanity mirror across the room.

“We used this plaster on the walls throughout the house,” Fishman says. “They provided a jumping-off point for the bathroom’s palette.” The plaster honors the Spanish Revival architecture and adds texture, depth and an organic feel to the room. “In the shower, there’s a layer of waterproofing under the cement, then the plaster, then a sealer,” Fishman says. This product is similar to tadelakt, a waterproof Moroccan treatment.
