Why a sauna

Modern life doesn't leave much room for recovery.

Decades of research link regular sauna use to measurable improvements in heart health, stress, sleep, and longevity.

63%

lower risk of fatal heart disease among people who sauna 4–7 times a week, versus once.

Laukkanen et al., JAMA Internal Medicine, 2015

61%

lower stroke risk for frequent sauna bathers in a 15-year Finnish cohort.

Kunutsor et al., Neurology, 2018

77%

lower risk of psychotic disorders linked to regular sauna use; benefits also seen for mood.

Psychosomatic Medicine, 2018

No commute necessary

The last thing you want after a long day is a drive to the gym.

Step outside, not out of the house.

You'll get a confirmation email right away. When your order ships you'll get tracking, and one to two days before delivery our team calls to schedule an appointment.
Lead times vary by model and are listed on each product page. Once it ships, transit is usually 3-7 business days.
Most traditional saunas take about 1-2 full days for two people to assemble. They are designed for DIY assembly and include clear instructions, but they are still a real project and not something you should expect to knock out in an hour or two. Plan on using basic tools like a power drill/driver, level, rubber mallet, and standard hand tools. Infrared saunas are typically much quicker to assemble, usually taking about 3-4 hours with two people. If you want us to assemble it for you, we have assembly services available in select areas.
Anything flat, stable, and free of pooling water. A wooden deck, concrete pad, pavers, or gravel all work. We don't recommend setting it directly on turf.
Most 6–9kW heaters run on 240V and need their own dedicated circuit wired by a licensed electrician. The LED lighting runs on standard 120V. We'll walk you through exactly what your chosen heater needs.
