Indoor or Outdoor Sauna: Which One Actually Fits Your Home?
An indoor infrared sauna is the easy one: it plugs into a normal outlet and sits in a spare room. An indoor traditional sauna needs its own wiring and a room that can handle steam. An outdoor sauna needs a level base, power run to the backyard, and a yearly coat of wood protection. The cheapest sauna is the one your house can actually accommodate.
People shop for saunas the way they shop for jeans: by looks, then discover the fit. The question of indoor or outdoor looks like a style choice. It is really a question about electricity, ground, and weather. Here is how to figure out which one your home can take, using real numbers from our catalog.
What does an indoor infrared sauna need?
Very little, which is its whole appeal. The 1-person infrared cabin in our catalog runs on a standard 120-volt outlet and lists no electrician required. It measures 75 inches tall, 46 wide and 40 deep, weighs 330 pounds, and goes together with two people and a screwdriver. It is a dry heat, so the room does not turn into a swamp.
The catch is that it lives in the house, so you need a spare corner with a ceiling tall enough and a path wide enough to get the panels in.
What does an indoor traditional sauna need?
More. The 2-person indoor traditional sauna in our catalog uses a 3.5 kW electric stove on a dedicated 220-volt circuit, and the listing says an electrician is required. You pour water on stones to make steam, so the listing recommends a floor drain nearby. That is not a detail. It is the difference between a sauna room and a damp basement.
What does an outdoor sauna need?
Ground, power, and a bit of upkeep. Our outdoor cube sauna is about 53 by 51 inches and nearly 82 inches tall. It ships on one pallet weighing 990 pounds, and the maker says two people can assemble it in about a day. Then the list of homework begins:
- A level, stable base. The kit does not include one, and a sauna on a slope is a very slow-motion problem.
- Power. Most electric sauna heaters need a 240-volt hardwired circuit, and the lights need a regular outlet. Getting that to a backyard can mean running a buried line. Have a licensed electrician do it, and check whether your area requires a permit.
- Yearly wood care. The maker calls for a wood preservative at least once a year.
- A careful first heat-up. The maker specifies a supervised first heating of about two hours.
And the weather gets a vote. A sauna outside in winter has to heat a cabin that started the day at freezing, so the warm-up takes longer than it would indoors. That is physics, not a defect.
How do they compare?
| Indoor infrared | Indoor traditional | Outdoor traditional | |
|---|---|---|---|
| Power | Standard 120-volt outlet | Dedicated 220-volt circuit | 240-volt circuit for the heater, outlet for lights |
| Electrician | Not required | Required | Required, plus getting power outside |
| Steam | No, dry heat | Yes, wet or dry | Yes, wet or dry |
| Where it goes | A spare room corner | A room with a nearby floor drain | Level ground in the yard |
| Ongoing care | Wipe down | Wipe down, watch moisture | Wood protection every year |
| Starting price in our catalog | $1,479 | $3,349 | $6,899.97 with a heater |
Prices as listed in October 2026. The outdoor cabin alone is $5,399.97 and the heater is a separate option.
Which one fits your home?
- Renter, small space, no electrician in sight: indoor infrared.
- Homeowner with a basement or garage and a wiring budget: indoor traditional, if you want steam and have a drain.
- Yard, patience, and a weekend for assembly: outdoor, with an electrician booked before the pallet arrives.
If you are not sure which type matches your routine, that is a separate question, and infrared vs. traditional covers it.
Common questions
Can I put an infrared sauna outdoors?
Only if the maker says the cabin is built for it. Ours is an indoor cabin. Outdoor saunas are built with weather in mind, including roofing and treated wood.
Does an outdoor sauna need an electrician?
For an electric heater, yes. Most need a 240-volt hardwired circuit, and running power to a yard may involve a buried line and a permit. Check your local rules.
Does an indoor sauna need a drain?
A traditional sauna that makes steam benefits from a floor drain nearby, and our indoor listing recommends one. A dry infrared cabin does not.
How long does it take to assemble a sauna?
The maker of our outdoor cube says two people can assemble it in about a day. The indoor infrared cabin also needs two people and basic tools.
What upkeep does an outdoor sauna need?
The maker calls for a wood preservative at least once a year and again after heavy use, and for wiping the benches and letting the cabin dry after each session.
Where this fits
Where the sauna lives is only half of the plan. The other half is how often you will use it and when it enters your week. Find My Protocol matches your answers to one of four starting points and a week by week plan. It takes about two minutes and does not require a purchase.
