Indoor saunas

A sauna that feels like part of the house.

A big part of what we do happens indoors. We build custom saunas into new homes alongside your builder, and we turn rooms and unused space in existing homes into high-end saunas. Either way, it's designed to look like it was always meant to be there.

Building a new home

We work with your builder.

Bring us in early and the sauna gets planned into the floor plan, not squeezed in later. We coordinate with your builder and trades so it blends seamlessly into the living space, from framing to the final trim. Our saunas have been featured in the Parade of Homes.

  • Planned with your builder early
  • Coordinated with the trades
  • Finishes that match your home
  • Parade of Homes experience

Remodeling your home

We convert the space you have.

A spare bedroom, a corner of the basement, an oversized closet or bathroom, part of the garage. We remodel unused space into a high-end custom sauna, built to hold heat and handle moisture properly for years of use.

  • Room-to-sauna conversions
  • Layout planned for your space
  • Insulated to hold the heat
  • High-end finishes

How we build

From the blueprint up.

Scroll through a build, from the first drawing to the night it's ready for first heat.

From drawing to first löyly

Your sauna, built around your site.

Every build starts with a visit to your property. Dan plans the footprint, the power for the heater and the view from the top bench, then builds it start to finish.

  2. Site visitSize, layout and power, set in person.
  3. BuildFoundation to finish, one crew.
  4. First heatWe walk you through the heater and care.

Optional upgrades

Make it yours.

Two popular add-ons we can build into your sauna. Here's what each one does, and what it doesn't, so you can decide if it's worth it for you.

LED-lit salt panels

A feature wall of Himalayan rock-salt blocks, lit from behind with LEDs so the whole wall glows a warm amber.

Why people add them

  • A soft, warm glow that makes the sauna feel calmer, especially at night
  • A one-of-a-kind feature wall with natural texture and color
  • Dimmable lighting you can set to the mood

Good to know

  • We place the wall away from the heater and the water bucket. Salt doesn't like water splashing on it.
  • Works best in a well-ventilated sauna that dries out after use. Clean it with a dry brush, never a wet cloth.
  • Individual blocks can be replaced if one ever gets damaged.
  • You'll see health claims for salt walls online. The research behind them is thin, so we recommend them for how they look and feel.

Infrared (IR) panels

Slim panels set into the walls or behind the benches that warm your body directly with radiant heat. Paired with a traditional heater, you get a hybrid sauna.

Why people add them

  • Gentler heat: infrared sessions usually run around 120–140°F, compared with roughly 150–190°F in a traditional sauna
  • Great for anyone in the family who finds a hot traditional sauna too intense
  • Two kinds of session in one room: classic heat and steam, or a lower-temperature infrared session
  • Many people use infrared to relax after a workout, and early research on post-workout recovery is promising

Good to know

  • IR panels need their own wiring, so they're easiest to plan in from the start. We'll size them for your room.
  • As with any sauna, check with your doctor first if you're pregnant or have heart or blood-pressure concerns.
