Where it goes

Your sauna, your space. Almost anywhere you imagine it.

Big space or small, we design the sauna around what you have. Here are some of the spaces we transform most often.

The most popular spot. Basements bring the ceiling height, the solid floor and the privacy.

Built off the primary bath so it shares plumbing and drainage, ideal for a smaller footprint.

A guest or bonus room you rarely use converts cleanly, with room for a fuller bench layout.

Yes, really. A walk-in closet or the space under the stairs fits a compact one-to-two-person build.

Insulated garages make excellent sauna space, with room to add a cold plunge alongside.

Building or remodeling? Bring us in early and the framing, wiring and ventilation are right from day one.

The case for indoor

The best sauna is the one you’ll actually use.

When your sauna is just steps from your bedroom, bathroom, or home gym, it becomes part of your routine, not something you have to plan around. That’s the beauty of building it indoors.

Steps away, not a trip away.No coat. No cold walk. Just step inside and turn on the heat, whether it’s first thing in the morning or a Tuesday night.
Built into the space you already have.A basement corner, spare bathroom, unused closet, or something completely unexpected, we design the sauna around your space.
Your ritual, year-round.January or July, snow or sunshine, an indoor sauna gives you the same experience every day of the year.

What we check

Before we build, we do the homework

Every space is different, so we start by seeing yours. We’ll assess the details, recommend what works best, and handle the technical side. You just bring the vision.

StructureCeiling height

Enough headroom for a proper bench-to-ceiling heat gradient.

AirVentilation

Fresh-air intake and exhaust so the room breathes and the heat stays even.

PowerElectrical service

Most builds want a dedicated circuit. We check your panel has the capacity to spare.

MoistureVapor barrier

The detail that protects your house. We seal the room so heat and steam never reach your framing.

FloorFlooring & drainage

A surface that shrugs off heat and the occasional splash, with a drain where it makes sense.

AccessDoor & egress

How the door swings, how you get in and out, and how it sits in the room.

"We converted a bathroom we were not using into a sauna. BEST decision ever! Working with the team from Home sauna was so seamless. From planning the layout to the install, they were a joy to work with. The attention to detail was amazing. Our guests and even the inspectors from our town complimented us on how good it all looks. We recently had some question after using the sauna and Robbie and Ryan stopped by a day later. Amazing customer service!!"

"We had a great experience working with The Home Saunas. From the build process to the final details, they consistently made sure I was satisfied as a customer. Anytime I made a request or had a question, they were happy to help and genuinely did their best to make it happen.  We did run into an issue with one of the heaters that came from the manufacturer, but as soon as I informed them, they acted quickly and helped resolve it. It was very reassuring to know they were on my side and actively working to find a solution."

"We finished an outdoor sauna and cold plunge project with Ryan and his crew at The Home Sauna. Throughout the entire process, he provided helpful answers and suggestions and could not have been nicer. I can recommend this company without reservations of any kind. Quality workmanship from people who understand sauna culture. We are grateful we found them."
