Few things irk a professional designer like living with a drab, dysfunctional interior. For Cillesa Ullman, one sore spot in her 1960s post-and-beam home in Oakland, CA, was the tiny, no-frills guest-room bath on the lower level. “I could not wait to tear it out­, so I literally did most of the demo myself,” she says. Her plan: Enlarge the space by relocating a laundry room and bedroom closet, and move the doorway so the bath could serve the entire floor, which was renovated to create another bedroom. To add a feeling of luxury to the new bath, Cillesa incorporated heated floors, a spa tub, and sleek new fixtures and cabinetry. She landed on her color inspiration when she came across a penny tile glazed in varying shades of aqua, “like a mermaid’s tail,” she recalls thinking. Using it to cover the tub skirt and line the shower floor, and echoing it on the double vanity, brought the space to life. “It’s both elegant and whimsical,” she says, “and with cool gray walls, it feels calming, too.”
