Grubb explained that the 3,000-square-foot residence is situated close to a state park, and the client wanted a design that would reflect this surrounding environment. They also desired an abundance of natural light and a space that would feel open, according to the designer. "The clients were very much into California earth tones," he said.

In providing this "earthy" look, Arch-Interiors chose Autumn Mist slate for the bathroom flooring, shower and Jacuzzi surround. "The clients wanted to reflect other finishes in the house," said Grubb. "It was important that this room related to the whole house. For them, this material was just right, and they found the variation in the stone fascinating."
