A Private Wellness Space, Built Into Your Bay Area Home

A home sauna is a long-term investment. It needs to be built correctly the first time, with materials that hold up and construction details that prevent moisture from getting into the structure. We manage every part of the build in-house, from design and permitting through framing, electrical, and finish carpentry. You get a fixed estimate before work begins, daily updates throughout, and a 1-year workmanship warranty when the job is done.

Custom Sauna Types RP Restoration Designs and Builds

Traditional Finnish / Nordic Saunas

We build authentic Finnish saunas with a kiuas heater, sauna stones, loyly bench layout, and wood-burning or electric heat.

Indoor Saunas

We build custom indoor saunas into spare rooms, basements, and bathrooms with correct insulation, vapor barriers, and ventilation.

Outdoor Saunas

We design and build outdoor sauna structures on concrete or paver bases with weatherproof cladding and full electrical installation.

Infrared Saunas

We install full-spectrum infrared sauna rooms with low-EMF panels, smart temperature controls, and precision-framed enclosures.

Materials Built to Perform: Cedar, Spruce, and Thermowood

The wood inside a sauna absorbs heat, withstands repeated humidity cycles, and makes direct contact with bare skin. Material selection is a performance decision, not a finish choice. RP Restoration specifies Western Red Cedar for its natural moisture resistance and aromatic warmth, Nordic Spruce for its clean grain and dimensional stability, and Thermowood for outdoor builds and high-use installations where maximum durability is required.

Cabin House Remodeling

Designed for the Bay Area Climate: Humidity, Salt Air, and Peninsula Conditions

Building a sauna on the Bay Area Peninsula requires materials and construction details matched to the local climate. Coastal fog, salt air, and thermal cycling accelerate wood degradation when the specification is wrong. We use Thermowood for all outdoor cladding, Western Red Cedar for indoor benches and walls, and detail every vapor barrier on the warm side of the insulation. These are not upgrades. They are the baseline on every project we build.
