The best home sauna is the one that fits your space, your electrical supply and the kind of heat you enjoy, because the sauna you use three or four times a week beats a bigger one you rarely turn on. Start by choosing between infrared and traditional heat, size it to the number of regular users, then check wood quality, safety listings and after-sales support.

## Step 1: Choose the type of home sauna

There are three main home sauna types, plus hybrids that combine two heat sources.

| Type | Typical temperature | Humidity | Power | Warm-up | Best for |
|---|---|---|---|---|---|
| Infrared sauna | 110-135 °F (43-57 °C) | Low | Often 110-120V plug-in for 1-2 person models | 10-20 min | Small indoor spaces, people who prefer gentler heat |
| Traditional dry sauna (electric stove) | 150-195 °F (66-91 °C) | Low, raised briefly by water on rocks | Usually dedicated 240V circuit | 30-45 min | Classic Finnish experience, hottest sauna sessions |
| Wood-burning sauna | 150-195 °F (66-91 °C) | As traditional | No electricity for heat | 45-60 min | Outdoor and off-grid sites |
| Steam room (wet sauna) | About 110-120 °F (43-49 °C) | Near 100% | Steam generator, 240V | 10-20 min | Moist heat; needs waterproof room |

Temperature ranges for infrared and traditional saunas are from [Cleveland Clinic](https://health.clevelandclinic.org/infrared-sauna-benefits); steam room figures are typical operating ranges. For the detailed comparison, read [infrared vs traditional sauna](/guides/infrared-vs-traditional-sauna/) or the overview of [types of saunas](/guides/types-of-saunas/).

### Infrared sauna options

Infrared saunas use emitters that warm the body directly. Far infrared (FIR) refers to wavelengths of roughly 3-1,000 µm; "full spectrum" cabins add near and mid infrared emitters. Common heater types:

- **Carbon fiber panels**: large surface area, even heat; low-EMF versions are available.
- **Ceramic emitters**: compact, hotter surface, faster warm-up.
- **Full spectrum (red glass or combined emitters)**: near, mid and far infrared in one cabin.

### Traditional sauna options

A traditional sauna heats air with an electric stove covered in rocks. Pouring water on the rocks creates löyly, the Finnish term for the burst of steam that raises humidity for a few minutes. It is the only option if you want the hottest sauna experience and steam on demand.

## Step 2: Decide indoor or outdoor

**Indoor sauna for home** use is the most common choice. Basements, bathrooms, garages and spare rooms all work. You need a level, hard floor (tile, concrete, vinyl), clearance above the cabin, and a nearby outlet or circuit. See [bathroom sauna ideas](/guides/bathroom-sauna/) for master bath layouts.

**Outdoor saunas**, including barrel and cube designs, need a foundation, weather-resistant wood and roofing, and outdoor-rated wiring. They free indoor space and pair well with a cold plunge.

## Step 3: Pick the right size

| Size | Approximate interior footprint | Typical user | Notes |
|---|---|---|---|
| 1-person | 36 x 36 in (90 x 90 cm) | Solo user, apartment | Often 120V infrared; sit-upright only |
| 2-person | 47 x 40 in (120 x 100 cm) | Couples, small home | Most popular home size |
| 3-person | 60 x 40 in (150 x 100 cm) | Families, room to recline | Corner layouts save space |
| 4- to 6-person | 72 x 60 in (180 x 150 cm) or larger | Large families, entertaining | Usually 240V; traditional heat common |

Allow roughly 24 inches (60 cm) of bench width per seated person and about 6.5-7 ft (200-210 cm) of interior ceiling height for traditional saunas; much more height wastes heat. A small home sauna is more efficient to heat, so size for regular users, not occasional guests. The [sauna finder tool](/tools/sauna-finder/) matches cabins to room dimensions and user count.

## Step 4: Check the electrical supply

Electrical requirements narrow your options fast.

- **110-120V plug-in.** Many one- and two-person infrared saunas run on a standard household circuit, ideally dedicated. Check the amperage on the spec sheet.
- **220-240V hard-wired.** Most traditional heaters and larger infrared cabins need a dedicated 240V circuit. A 6 kW heater draws 25 amps at 240V before any safety margin.
- **Have an electrician confirm** breaker size, wire gauge and GFCI requirements under local code.

Our [sauna electrical requirements guide](/guides/sauna-electrical-requirements/) covers circuit sizing in detail.

## What to look for in a sauna: quality checklist

Use this checklist when comparing any sauna for sale, whether a home sauna kit or a fully assembled cabin:

- **Wood species and grade.** Canadian hemlock is light-colored and stable; western red cedar is aromatic and naturally rot-resistant. Look for kiln-dried, clear (knot-free or low-knot) boards.
- **Wall construction.** Thicker tongue-and-groove panels hold heat better; ask about wall thickness and insulation.
- **Heater specification.** Total wattage, emitter type and placement for infrared; kW rating matched to room volume for traditional heaters.
- **Safety listing.** In the US, look for an ETL or UL mark from an OSHA-recognized Nationally Recognized Testing Laboratory. Electric sauna heaters are expected to meet [UL 875](https://gocodebook.com/library/us/ca/ca-mechanical-code/chapter-9-installation-of-specific-appliances/939.1-electric-sauna-heaters.-sauna-heaters-shall-comply-with-ul-875-and-shall-be-installed-in-a); internationally, [IEC 60335-2-53](https://webstore.iec.ch/en/publication/68677) covers sauna heaters and infrared cabins. In the EU, look for CE marking.
- **Door and glass.** Tempered safety glass, a door that opens outward and no lock.
- **Controls.** Clear temperature and timer controls inside and/or outside the cabin; an automatic shutoff timer.
- **Ventilation.** Intake and exhaust vents, which keep the air fresh and help the wood dry.
- **Assembly.** Panels that buckle or clip together, clear instructions and a list of tools needed.
- **Support.** Warranty terms in writing and access to spare parts, such as emitters, control boards and heater elements.

### Made in USA or imported?

Searches for American made saunas are common, and buyers reasonably want quality and accountability. Country of origin matters less than verifiable specifications: wood grade, heater components, an NRTL listing for the market you live in, and a seller who can supply parts. Ask any sauna manufacturer for the certification file number and spec sheet, and compare cabins on those facts.

## How much does a sauna cost?

Sauna price varies widely, and the main cost drivers are:

1. **Size.** Each added seat means more wood, more heater capacity and higher freight.
2. **Heater type.** Basic carbon infrared is generally the least expensive; full spectrum and premium traditional heaters cost more.
3. **Wood species.** Western red cedar usually costs more than hemlock or spruce.
4. **Indoor vs outdoor.** Outdoor saunas add roofing, weatherproofing and a foundation.
5. **Installation.** Electrician fees for a 240V circuit, delivery and assembly.
6. **Running costs.** Electricity per session depends on heater kW and local rates.

## Health and safety before you buy

Regular sauna use is associated with health benefits in observational research. A [2015 study in JAMA Internal Medicine](https://jamanetwork.com/journals/jamainternalmedicine/fullarticle/2130724) followed 2,315 Finnish men for a median of 20.7 years and found that those using a sauna 4-7 times per week had lower rates of fatal cardiovascular disease and death from all causes than once-weekly users. A [2018 systematic review](https://pmc.ncbi.nlm.nih.gov/articles/PMC5941775) found regular dry sauna use was generally well tolerated by healthy adults. Neither proves cause and effect.

This article is general information, not medical advice. People who are pregnant, have heart disease, low or high blood pressure or other conditions should talk to a doctor before using a sauna. [Harvard Health](https://www.health.harvard.edu/staying-healthy/saunas-and-your-health) advises limiting sessions to 15-20 minutes, avoiding alcohol and drinking two to four glasses of water afterward.

## Where to buy a sauna

You can buy from specialty retailers, home improvement stores, installers or online sellers. Whoever you buy from, ask for the spec sheet, certification details, assembly manual and warranty before paying, and confirm how spare parts are supplied.

Mars Sauna is a manufacturer with 213 catalogue models across 9 product lines, including hemlock and red cedar cabins with carbon, low-EMF, full spectrum and ceramic infrared heaters, and traditional electric stove saunas. Most cabins are offered in 110-120V or 220-240V builds, and many models list CE and ETL. Retailers and distributors can [browse all sauna models](/saunas/) or [request a quote](/contact/).

## Key takeaways

- Choose heat type first: infrared for gentler heat and plug-in convenience, traditional for 150-195 °F (66-91 °C) and steam on the rocks.
- Size for regular users, with about 24 inches (60 cm) of bench per person; smaller saunas heat faster and cost less to run.
- Confirm your electrical supply early: many 1-2 person infrared saunas run on 120V, most traditional heaters need a dedicated 240V circuit.
- Look for kiln-dried hemlock or cedar, tempered glass, an ETL or UL listing and available spare parts.
- Total cost includes delivery, electrical work and running costs, not just the cabin.

## FAQ
### What is the best type of sauna for home use?
The best home sauna depends on what you want from the heat. Infrared saunas run at about 110-135 °F (43-57 °C), often plug into a standard outlet and suit small indoor spaces. Traditional dry saunas reach 150-195 °F (66-91 °C), allow steam from water on the rocks and usually need a 240V circuit. Choose the experience you will use regularly.

### What should you look for when buying a sauna?
Look for the right size for your household, a heater type you like, solid kiln-dried wood such as hemlock or cedar, an electrical safety listing such as ETL or UL, a voltage that matches your home, clear assembly instructions, available spare parts and a warranty in writing. Check door glass, bench width and ventilation before you buy.

### How much does a home sauna cost?
Home sauna cost depends mainly on size, heater type, wood species, indoor or outdoor build, and installation. Small one- or two-person infrared cabins are generally the least expensive; large traditional or outdoor saunas with electrical work cost the most. Add running costs, electrician fees and delivery. Our full cost guide breaks down each driver.

### What size sauna do I need?
Allow roughly 24 inches (60 cm) of bench width per seated person. A one-person sauna is often about 36 by 36 inches (90 by 90 cm), a two person sauna about 47 by 40 inches (120 by 100 cm), and a 4- to 6-person sauna about 72 by 60 inches (180 by 150 cm) or more. Add clearance for the door and heater.

### Is a dry sauna or steam sauna better?
Neither is better for everyone. A dry sauna, whether traditional or infrared, uses hot air or radiant heat at low humidity. A steam room runs at about 110-120 °F (43-49 °C) with near 100% humidity. A traditional sauna sits in between, because you can pour water on the rocks to raise humidity briefly. Choose by how you like heat to feel.

### Can you put a sauna in your house?
Yes. Indoor saunas fit in basements, bathrooms, garages, spare rooms and home gyms. Infrared models need only a level floor and a suitable outlet; traditional saunas need a dedicated 240V circuit sized to the heater, plus ventilation. Avoid carpeted floors, and check clearances to ceilings and walls in the installation manual.
