About Marin Sauna

Who We Are

We are experienced professionals dedicated to providing saunas quickly, at the right price, and with no hassles. We are customer first and our many past customers can attest to that! We would love to make your space come true — whether it be inside or out, custom or kit. We have seen everything in the industry, so we can guide you through any problem with ease. Call us today and we would love to help!

Our mission

To build saunas, hot tubs, and cold plunges good enough to outlast the homes they sit beside — and warm enough that you actually use them.

What we value

• Craft over speed. We would rather take an extra week on the bench detailing than hand over a build we are not proud of.
• Honest materials. Untreated cedar, hemlock, and Nordic spruce only — no veneers, no shortcuts, nothing that off-gasses at temperature.
• Real heat science. Rock mass, airflow, and humidity are engineered together, so your sauna delivers true Finnish löyly every time.
• One point of contact. The person who designs your sauna is the person who sees it through permits, framing, and final finish.

Our crew

We are a small team of finish carpenters and sauna builders based in San Rafael, trained on both Finnish and North American standards. We keep crews small and the work in-house, which means the people milling your cedar are the same ones hanging your door and setting your stones. Several of us came to this work through our own love of heat and cold therapy, and that shows in how we obsess over the details others skip — bench radius, backrest angle, the way a vent draws on a foggy morning.
