A sauna is an optional feature. Cedar and concrete create a recurring visual theme from the exterior to the interior.

The walls of the bathroom are covered in large, white ceramic tiles, with the exception of one side clad in reclaimed wood with an IKEA cabinet.

Another incorporation of the original fir beams can be seen in the bathroom’s medicine cabinet frame. An oak vanity and David Weeks Studio Boi sconces complete the space.

Lighting in the bathroom is provided by San Francisco-based Aion LED’s modular fixture system. The linear lighting mimics the redwood siding.

Nearby, the bathroom includes a composting toilet and a Home Depot sink on a pedestal Chris made from chunks of found wood.

Like many traditional Japanese bathrooms, Wilkin and Pini’s is clad almost entirely in wood.

Brigham works primarily with wood and Archuleta had recently been exploring the potential of glass fiber reinforced concrete, so those disparate but complementary materials became the main focus of the project. Together, the warm wood and the clean, minimalist concrete create a “warm and serene space, reminiscent of a spa,” says Brigham.

This bathroom, tiled in bright blue mosaic to offset the home’s limited materials and color palette, calls for a simple vanity. The sinks, toilets, and tubs are by Villeroy & Boch, while the faucets and towel rails are by Grohe and Avenir, respectively.

The bathroom includes a walk-in tub.

Sævik designed the wood tub in the bathroom, which features an adjacent sauna. The Inxx A5 faucet is by Mora.

At the opposite end of the house, the soaking tub gets almost daily use. The bath and shower fixtures are by Dornbracht

“A critical aspect of the project was the incorporation of natural light and ventilation within a broad footprint,” Simpson says. Conventionally private areas, like bedrooms and bathrooms, are therefore reinterpreted with more openness in mind. For instance, this bathroom’s skylights mirror those found throughout the rest of the property. The bathtub, basins, and showerhead were all purchased at the Australian retailer Reece.

The architects designed the large dining table, which is framed by the open kitchen, the wood-burning stove, and the garden beyond.

A linear sequence of eight, 12-foot bays extends the length of the home from rear bedrooms and an office to the open kitchen and living room space. The modest form, a reflection of the owners' desire for simplicity, required few materials: wood, concrete, and steel. Photo by Ron Johnson.

The Japanese-style bathroom, which is clad in teak, features a matching tub and sink by Bath in Wood.

The ultimate luxury: a hot bath in the clawfoot tub, with the fiberglass door open wide to the woods.

White tiles envelop the en suite master bathroom.

Set amongst the trees, with its simple form and earthy adherence to wood, the home fits in well. "Veronica and I walked the land for many months before we decided where to put the house," says Hirsh. "We had picnics there. We sat looking east. We sat looking west. We sat looking south. The site felt wonderful." Photo by Ron Johnson.

The subway tile-lined bathroom was kept as simple as possible, with Hansgrohe fixtures and cabinets made of vertical-grain Douglas fir above a top-mounted Duravit sink. Since installing a window was unfeasible given the bathroom's proximity to other properties, Storey added a skylight over the shower.

In modern bathroom vanities, timber can be used a number of different ways. It’s at its most basic in this simplistic modern bathroom, tied together neatly with matching shelving in the cut-out above.

The minimalist bathroom boasts Cararra marble surfaces, Hansgrohe faucets and shower fixtures, and a skylight by Velux.

The upstairs showers are particularly ingenious: Operable skylights loom above, and perforated, galvanized-steel platforms open up to spacious, sunken bathtubs.

The trip from garage to first floor is through a wood-clad spiral staircase that resembles a giant slatted barrel.

Benjamin Moore’s “Mountain Peak White” coats the western red cedar walls in the master bathroom, which is detailed with the same Carrara marble countertop seen in the kitchen. Waterworks tile covers the floor, and an Agape tub stands across from a vanity light fixture custom-made by the firm’s interior designer, Erin Martin.

The units don't even require foundations—simple ground screws from Krinner are enough to support them.

While it's not your traditional backsplash material, when properly prepared and treated, wood can make for an effective, functional, and beautiful backsplash. Here, the wood backsplash matches the wood of the nearby kitchen island in an otherwise white kitchen with white cabinetry.

The bedroom opens directly into the master bathroom to complete the open feel.

A porthole mirror and wood vanity deliver this bathroom, posted by @nossolar91, a slightly historical charm.

The bathroom features Chromtech tile, a Toto toilet, Kohler vanity, and powder-coated steel countertop.

Part of the master suite, the bright bathroom embraces texture and pattern. The space clad in bold, graphic tile and features a custom steel vanity.

The Salvatori marble tiles in the bathroom were added at the last minute, once everyone was confident that they would not put the project over budget.

Opposite the inner courtyard and master bedroom, the bathroom enjoys a view of the lush garden space. Polished concrete floors and walls, and white Carrara counters offer cohesion with the rest of the home. American Standard plumbing fixtures and reclaimed midcentury pendant lamps round out the space.

The diminutive Morsø wood stove and its hearth of local Criehaven beach stone gives off enough heat to warm the entire cottage.

"We composed the house to have its highest, brightest space in the middle," says Paul Raff. Warm wood stairs lead to the second floor, which houses guest bedrooms, bath, and a kitchenette for the family's frequent visitors.
