Since obtaining tiles in the right color blue proved impossible, the tiles were painted using “Cobalt” from SIGMA Coatings by NCS Colour.

“It’s like being on a tropical island where you can take a shower under the trees, except you’re actually in Warsaw,” says Karol.

The new powder room has Blackthorn wallpaper from Morris & Co, which was chosen for how its green and pink palette “bridges” the other spaces in the home, says Kara. Beckham Double Sconces from Visual Comfort flank a Tufa Modern Mirror from Scout and Nimble, over a marble sink.

Patricia designed the home without a pool, a fairly common feature on the island, for ecological and spatial reasons—so an understated yet oversize sunken bath is where the family cools off during heat waves. “We really tried to find an aesthetic that ‘speaks’ of the island,” says Patricia, “that expresses how natural materials can embrace beautiful spaces and how this type of design can also be considered luxurious.”

A “weird two-story closet” around the staircase, says Butcher, became the powder room on the first floor and a reading nook on the stair landing. The couple’s twelve-year-old suggested the forest theme, achieved with wallpaper from Murals Your Way and a log sconce from Unique Lighting Co on Etsy.

Matthew built the soaking tub from yellow Alaskan cedar. “There’s no finish on it, so every time the water hits it, you get this burst of cedar aroma,” says Matthew. Adds Holly: “It smells amazing.”

In a sophisticated main bathroom in Seattle, sea-green concrete floor tiles with a geometric pattern provide a lawn of color against wood walls and white tile. The paper lanterns are also a clear homage to the building’s Japanese inspirations.

An indoor swing adds a whimsical touch to the stone hearth and wood-burning stove just off the dining area.

The bathroom is decked out entirely in a material called Coosa, a plywood alternative that’s becoming popular in the boating and marine construction world. “The material can live underwater,” says Castillero.

In the first-floor bathroom, the mermaid backsplash Caleb carved plays off the Hygge & West “Mermaid” wallpaper.
