Indoor Saunas — A Sauna for Any Room

You don't need a backyard or a dedicated outbuilding to own a sauna. Indoor saunas fit in spare rooms, basements, bathrooms, garages, walk-in closets, and even apartments. Many infrared models plug into a standard 120V outlet, assemble in under an hour, and need no special ventilation or plumbing. We carry indoor saunas in infrared, traditional, and hybrid configurations from brands like Dynamic, Peak, Finnmark, Auroom, and Golden Designs. Every order ships free with 0% APR financing.

Shop by Heating Type

Infrared Saunas — The most popular choice for indoor use. Infrared saunas warm your body directly with light panels at 120–150°F, heat up in 15–20 minutes, and many 1–2 person models run on a standard 120V outlet. No steam, no special ventilation, minimal moisture — just plug in and go. Available in FAR infrared, full spectrum, and models with built-in red light therapy. Infrared is the best option for apartments, bathrooms, and rooms where a 240V circuit isn't available.

Traditional Indoor Saunas — The classic Finnish experience with an electric rock heater, temperatures of 150–195°F, and the option to pour water on the rocks for steam (löyly). Traditional saunas require a 240V dedicated circuit and produce more heat and moisture than infrared, so they're best suited for basements, dedicated sauna rooms, or bathrooms with adequate ventilation. If you want the full high-heat sauna experience at home, this is it. Browse our electric heaters and complete DIY sauna room kits.

Hybrid Indoor Saunas — Combine a traditional electric heater with infrared panels in one unit. Switch between traditional high-heat sessions, gentle infrared sessions, or run both simultaneously. Hybrids cost more and are typically larger, but they offer maximum flexibility if you don't want to choose between the two heating styles.

Where to Put an Indoor Sauna

Bathroom — One of the most popular spots, especially for sauna-shower combos. A compact 1–2 person infrared sauna fits in many master bathrooms, and the existing ventilation and waterproof flooring work in your favor. For a traditional sauna built into a bathroom remodel, see our bathroom sauna remodel guide for layout ideas, electrical requirements, and moisture management.

Basement — The ideal spot for a larger traditional or hybrid sauna. Basements typically have the ceiling height, floor space, and access to electrical panels needed for a full-size setup. Concrete floors handle moisture well, and the naturally cooler ambient temperature helps the sauna heater work efficiently. Just watch for moisture and mold prevention in below-grade installations.

Spare bedroom or closet — A freestanding infrared sauna fits in most spare rooms without any renovation. Many 1-person models are under 3' x 3' and fit in a walk-in closet. Just make sure you have an outlet nearby and adequate ceiling clearance (usually 6.5–7').

Garage — A popular choice when you don't want to give up living space. Garages typically have 240V access (from a dryer or EV charger circuit), plenty of room, and concrete floors. Insulation matters more here if your garage isn't climate-controlled — the heater will work harder in an unheated garage during winter.

Apartment — Yes, you can have a sauna in an apartment. Plug-in 120V infrared saunas need no permanent installation, produce no steam, and can be disassembled if you move. Just confirm with your landlord or HOA and check that your outlet can handle the amperage. See our placement guide for apartment-specific tips.

Sauna-Shower Combos

Combining a sauna with a shower is one of the most searched-for home wellness setups, and for good reason — stepping from a hot sauna directly into a cool shower is the simplest form of contrast therapy. There are a few ways to do it:

Freestanding sauna near your shower — The simplest approach. Place a freestanding infrared sauna in your bathroom or an adjacent room and use your existing shower. No renovation needed.

Built-in sauna room with adjacent shower — For bathroom remodels, you can build a traditional sauna room with a glass door that opens directly into a shower area. This is the premium setup. Our bathroom remodel guide and free layout designs show how to plan the space.

DIY sauna room kits — Our complete DIY sauna room kits include pre-cut wood panels, a heater, and all materials to build a custom sauna room into an existing space. Perfect for basements, master bath renovations, and garage conversions. Pair with our custom sauna design service for a tailored layout.

Shop by Size

1-Person Saunas — The most compact option. Typically under 3' x 3', these fit in closets, small bathrooms, and studio apartments. Almost all are infrared and plug into a standard outlet.

2-Person Saunas — The most popular indoor size. Around 4' x 3.5' with enough room for one person to stretch out or two to sit comfortably. Available in infrared and traditional configurations.

3-Person & 4-Person Saunas — For basements, dedicated sauna rooms, or larger bathrooms. These offer more bench space and heater coverage. Larger models may require 240V wiring.

Electrical Requirements

Most infrared saunas in the 1–2 person range operate on 120V and plug into a standard household outlet — no electrician needed. Larger infrared models and all traditional electric sauna heaters require a dedicated 240V circuit installed by a licensed electrician. Before purchasing, check the specific product's electrical specs and read our electrical requirements guide and electrical code by state guide. Need an electrician?

Frequently Asked Questions

Do indoor saunas need ventilation?

Infrared saunas produce very little moisture and generally don't need special ventilation beyond a normally ventilated room. Traditional saunas with steam (löyly) do produce moisture and benefit from a bathroom-style exhaust fan or a vent to the outside, especially in enclosed spaces. Our moisture and mold prevention guide covers ventilation requirements by sauna type.

Will a sauna damage my floors?

Freestanding infrared saunas sit on the floor and produce minimal heat and moisture underneath — they're safe on hardwood, tile, laminate, and carpet (though tile or concrete is ideal). Traditional saunas with steam are best on tile, concrete, or waterproof flooring. See our guide on the best floor materials for saunas.

Can I put a sauna in my apartment?

Yes — a plug-in 120V infrared sauna works in most apartments. They produce no steam, need no permanent installation, and can be disassembled if you move. Check with your landlord or building management first, and confirm your outlet can handle the amperage (typically 15A).

How much does it cost to run an indoor sauna?

A typical 1–2 person infrared sauna uses 1,000–1,800 watts and costs about $0.15–0.30 per session at average US electricity rates. Traditional electric sauna heaters draw more power (4,500–9,000+ watts) and cost roughly $0.50–1.50 per session depending on heater size and session length. Running a sauna 3–4 times per week adds roughly $5–25 per month to your electric bill.

Do I need a permit for an indoor sauna?

Plug-in freestanding infrared saunas typically don't require a permit. Built-in traditional sauna rooms with hardwired electrical may require an electrical permit depending on your jurisdiction. If you're doing a bathroom remodel that involves moving walls or plumbing, you'll likely need a building permit. Check our sauna permit guide for specifics.

What's the best indoor sauna for a small space?

For tight spaces, a 1-person infrared sauna is your best bet — models like the Finnmark 1-person full spectrum or Dynamic Barcelona fit in under 12 square feet, plug into a standard outlet, and assemble in about an hour. For a custom fit, our DIY sauna room kits can be sized to your exact space.
