It started with a simple wish list: a sauna, and patio doors leading straight out to the pool. Positioned between the lower-level gym, pool, and hot tub the clients had already built, this guest bathroom became the missing piece in their wellness routine, along with a fresh look worthy of the home's roots and other recent updates. Space was the defining challenge. To accommodate a luxurious infrared sauna without compromising the room's everyday function, the bathroom expanded into its own closet, and the sauna enclosure was clad in matching wood while the ceiling remained open, drawing on the room's full height rather than closing it in. A walk-in shower with digital controls, paired with a niche set into the pony wall, kept the footprint efficient without feeling confined, while a navy vanity with white quartz countertop echoes the palette of the adjacent guest bedroom. Underfoot, an organic marble mosaic in a floral pattern brings a touch of whimsy to an otherwise classic material.
