Why Choose an Indoor Sauna? The Ultimate Convenience
An outdoor sauna is a wonderful escape, but an indoor model is the champion of convenience. It seamlessly integrates wellness into your daily life.
- Unbeatable Proximity: Located in your master bath, home gym, or basement, your sauna is always just a few steps away. This makes it incredibly easy to build a consistent routine.
- Total Privacy: Enjoy your wellness sessions in the complete comfort and privacy of your own home. No need to worry about nosy neighbors.
- Year-Round Access: Rain, snow, or shine, your personal retreat is always ready and waiting for you, with no need to brave the elements to get there.
"I never thought I had the space for a sauna, but the 2-person infrared model fit perfectly in our basement. The plug-and-play setup was so easy. Now it's my go-to spot to de-stress after work, and my morning stiffness is gone."
- Emily R., Verified Buyer
Step 1: The Big Decision — Infrared vs. Traditional Heat
This is the most important choice you'll make, as it defines your entire sauna experience.
Infrared Saunas: Gentle, Soaking Warmth
Operating at a lower temperature (120-140°F), an indoor infrared sauna uses radiant heat to warm your body directly, rather than heating the air. Many users find this gentle warmth allows for longer, comfortable sessions of 20-30 minutes. They also heat up quickly, often ready in just 10-15 minutes. For a complete breakdown of the technology, check out our detailed Infrared vs. Dry Sauna comparison.
Traditional Saunas: Authentic, Steamy Heat
The classic Finnish experience, a traditional sauna uses a heater to warm the air to 160-195°F. You can pour water over hot stones to create bursts of steam, or löyly, for that iconic, robust heat. They take a bit longer to heat up (20-40 minutes), and sessions are typically shorter rounds of 10-15 minutes. If you love high heat and steam, this is the choice for you.

Step 2: Finding the Right Fit & Style for Your Space
Sizing by Person
The first question is always, "will it fit?" Indoor saunas are designed to be space-efficient. We offer models for every need, from cozy 1-person saunas perfect for a quiet solo session, to popular 2-person saunas, all the way up to family-sized 4-person saunas.
Space-Saving Designs
If you're tight on space, don't worry. A corner sauna is a brilliant design that tucks neatly into the corner of a room, maximizing your floor space while still providing a roomy interior.
Pro Tip:
Before you buy, use painter's tape to mark the sauna's footprint on your floor. This helps you visualize the space it will occupy and ensures you have enough room to walk around it comfortably.
Wood & Aesthetics
The wood you choose affects the look, scent, and feel of your sauna. Cedar offers that classic, aromatic scent, while Hemlock and Aspen are great hypoallergenic options with a bright, modern look. For a full comparison, our guide to sauna wood types has all the details.
Step 3: Powering Your Sauna — Plug-and-Play or Pro Install?
This is a huge factor for indoor saunas and, luckily, it's simpler than you think.
120V "Plug-and-Play" Saunas
One of the biggest advantages of many 1- and 2-person infrared saunas is that they are designed to run on a standard 120V household outlet. This means no special wiring is needed. However, it is critical that the outlet is on a dedicated circuit to avoid tripping your breaker. We strongly recommend consulting a licensed electrician to confirm your chosen outlet is suitable.
240V Dedicated Circuit Saunas
All traditional saunas and larger infrared models are more powerful and require a 240V dedicated circuit, similar to an electric stove or clothes dryer. This installation must be performed by a qualified and licensed electrician to ensure safety and compliance with all local electrical codes. This is not a DIY job. For a complete technical overview, our guide to sauna electrical requirements has everything you and your electrician need to know.
Step 4: Assembly & Installation
You might be picturing a complicated construction project, but most modern indoor saunas are surprisingly simple to put together.
Easier Than You Think
Nearly all of our indoor saunas are sold as DIY sauna kits. They arrive in panels that are designed to clip, slide, or buckle together. With a friend and a few basic tools, most people can have their sauna fully assembled in just a couple of hours. It’s more like assembling furniture than building a room. Always follow the manufacturer's specific installation manual to the letter to ensure a safe and secure build.
Step 5: Safety & Best Practices
Relaxing is the goal, and staying safe is how you get there. Following a few simple rules ensures every session is a good one.

Your Indoor Sauna Questions, Answered (FAQ)
Will the heat or steam damage my walls?
No. Indoor saunas are fully self-contained, insulated units. They are designed to keep the heat and moisture inside. As long as you have basic ventilation in the room itself (like a standard bathroom fan), you have nothing to worry about.
How much space do I need around the sauna?
It's a good idea to leave a few inches of clearance on all sides to allow for proper air circulation around the unit. Always check the specific model's manual for exact clearance requirements.
Can I put an indoor sauna on carpet?
It's not recommended. The best flooring is a hard, waterproof surface like tile, concrete, vinyl, or laminate. Placing a sauna on carpet can trap moisture and lead to mold or mildew over time.
Ready to Bring the Spa Home?
Choosing an indoor sauna is a simple path to daily wellness. The process is straightforward: decide which heat experience you prefer, measure your space, and confirm your power setup. It's a rewarding investment in your health that pays dividends in relaxation and recovery for years to come.
