Curated indoor and garage ready saunas plus guidance from our sauna specialists so you can plan a safe, long lasting setup with confidence.
Why choose a garage sauna
A sauna in the garage lets you enjoy spa level heat therapy without giving up an indoor room or walking out into the weather. When planned correctly, a garage sauna becomes a quiet ritual space for relaxation, recovery, and stress relief that sits only a few steps away from your front door.
- Save indoor square footage Use an underutilised bay or corner instead of sacrificing an office, bedroom, or living area.
- Easy access to power and utilities Garages are often close to the main electrical panel which helps your electrician run a dedicated line for the heater or infrared system.
- Natural privacy and noise separation The garage location keeps heat, light, and post workout noise away from the main living space.
- Flexible layouts Open floor plans and higher ceilings make it easier to fit two person, three person, or larger cabin layouts.
- Perfect recovery partner for a home gym Many people combine their garage sauna with weights, cardio equipment, or a cold plunge for a full recovery zone.
Can you safely put a sauna in your garage
In many homes you can absolutely install a sauna in the garage once a few core conditions are met. Thermal Sanctum always recommends confirming the details of your project with a qualified electrician and installer, yet the checks below will help you understand what matters most before you order a cabin.
Local codes and safety
Most regions have specific rules for new electrical circuits and for any changes to a garage. Your installer or electrician can tell you whether you need permits and will make sure heater clearances and wiring follow code.
Ventilation and moisture
Traditional saunas create steam and humidity. Even infrared saunas warm the air. Your garage needs enough airflow to move warm moist air out and bring fresh air in so the cabin and surrounding structure stay dry over time.
Floor and structure
The sauna must sit on a level, stable, non slip base. Most concrete slabs are suitable, but areas that collect water may need interlocking mats, a raised platform, or a waterproof surface around the cabin.
Fire and air quality
Keep flammable items like paint, cardboard boxes, or fuel containers well away from your sauna. Many owners add a smoke detector and carbon monoxide alarm as an extra layer of protection in a garage environment.
If these basics check out, you are usually ready to focus on choosing the right sauna for your garage and planning the layout that suits your daily routine.
Choosing the right sauna for your garage
There is no single best sauna for garage setups. The right choice depends on space, electrical service, and the way you like to use heat therapy. Below is a simple way to think about your options.
Electric traditional garage saunas
Electric heaters with sauna stones create the classic Finnish style environment. Air temperatures are higher, and you can ladle water onto the rocks for steam.
Best for people who love intense heat, steam bursts, and a familiar spa style feel.

Infrared garage saunas
Infrared cabins warm the body directly with light based heaters. They usually run at lower air temperatures and often plug into a standard household outlet which can simplify a garage installation.
Best for gentle, comfortable sessions, quicker warm up time, and energy conscious use.

Hybrid and combo garage saunas
Hybrid cabins combine infrared panels with a traditional rock heater in the same unit. This gives you both quick lower temperature sessions and classic high heat with steam.
Best for households where different people like different styles of heat therapy.

Planning the size and layout of your garage sauna
A thoughtful layout keeps your garage sauna comfortable to use and easy to live with day after day. Start with a tape measure and a simple sketch.
- Measure width, depth, and ceiling height Mark out the area where you plan to place the cabin and note any doors, steps, windows, or pillars.
- Decide how many people will use the sauna regularly One to two person saunas fit tight corners. Three to four person saunas work well for couples, families, and friends.
- Leave breathing room around the cabin Most manufacturers recommend several inches of clearance for ventilation and maintenance. Your electrician also needs access to the control box and wiring.
- Plan a small landing zone Keep space for towels, hooks, a bench, and a mat so you are not stepping straight from concrete into the cabin.
To make browsing easier, Thermal Sanctum groups saunas by capacity. Many garage sauna projects focus on:
1 person sauna · 2 person sauna · 3 person sauna · 4 person sauna
Installation basics for a garage sauna
Every garage and sauna model is a little different, so the exact steps will vary. Thermal Sanctum always recommends using licensed professionals for electrical work and following the manufacturer instructions closely. The outline below will help you understand the typical stages of installing a sauna in the garage.
1. Prepare the space
Clear clutter, move flammable items away, and confirm that the floor is level and dry. This is also the time to add mats, a platform, or moisture resistant finishes if needed.
2. Plan electrical work
Infrared cabins often use a standard outlet. Many traditional electric heaters require a dedicated higher voltage circuit. Your electrician will size the breaker, cable, and connection points for your specific sauna.
3. Assemble the sauna
Prebuilt cabins arrive as panels that interlock according to the manual. Walls, ceiling, benches, and doors are installed in order which helps create a tight envelope and clean finish.
4. Connect and test
The electrician completes the wiring, then you test the controls, heater, and lighting. Initial warm up cycles help the wood dry and allow you to check ventilation and clearances.
Designing a calm wellness corner in your garage
A little design thinking turns a purely functional garage into a soothing sanctuary. Focus on warmth, light, and order so your garage sauna feels like a destination rather than a storage area.
- Use soft, warm white lighting instead of harsh overhead fixtures so your eyes can relax the moment you step into the space.
- Choose finishes that echo natural materials. Wood tones, stone inspired tiles, and neutral textiles balance the strong visual lines of a cabin.
- Add practical storage for towels, robes, slippers, and water bottles so the area stays uncluttered between sessions.
- Include a small bench or chair outside the sauna for cooling down, stretching, or preparing for the next round of heat.
- Consider simple sauna accessories such as thermometers, sand timers, aromatic oils, and headrests to personalise your ritual.
Quick answers for garage sauna projects
Do you need a permit for a garage sauna
It depends on local regulations. Many areas require permits for new electrical circuits or changes to the structure of a garage. Checking with your local authority or installer at the planning stage helps avoid delays later.
Is a garage better than an outdoor location
Both can work beautifully. A garage sauna is protected from wind, rain, and snow and usually sits closer to power and water. Outdoor saunas suit people who want a garden retreat. The right choice depends on your climate, plot, and how you plan to use the space.
How do you maintain a garage sauna
Wipe benches and backrests regularly, let the cabin dry fully between sessions, and keep the surrounding floor clean and dry. Follow the cleaning and maintenance guidance that comes with your sauna, including any warranty requirements from the manufacturer.
