Thinking about adding a sauna to your home? A custom sauna is one of the most luxurious and health-boosting upgrades you can make. But one of the first questions homeowners ask is: how much does a custom sauna cost?
The answer depends on several factors, including the type of sauna, the space you’re working with, and whether it’s part of a new construction or a remodel project.
Average Custom Sauna Costs
- Custom Dry Sauna (Traditional): Starts around $15,000 and can range up to $80,000+ depending on size, wood choice, and features.
- Combo Infrared/Traditional Sauna (Infrasauna): Adding infrared heat panels typically increases the price by about $10,000.
Cost Factors to Consider
- New Construction vs. Remodel
- In new builds, a sauna can be easily added while walls and electrical are being planned.
- In a remodel, you’ll need to factor in demolition, electrical upgrades, and relocating power to the sauna location, which adds cost.
- Size & Customization
- A small two-person sauna costs far less than a full spa-style room.
- Options like glass walls, custom benching, or ADA compliance (wider doors, turnaround space, etc.) add to the final price .
- Sauna Type
- Traditional Sauna – Uses an electric heater and sauna stones. Temperatures reach 150–190°F with the option to pour water for steam .
- Infrared Sauna – Uses heating panels, operates at lower temps (120–170°F), and delivers deep, body-penetrating heat .
- Combo (Infrasauna) – Best of both worlds; gives you flexibility but at a higher upfront investment.
Benefits of a Custom Sauna
- Health & Wellness: Regular sauna use supports relaxation, detoxification, muscle recovery, and even cardiovascular health .
- Custom Design: From wood species to lighting and bench styles, you get exactly the look and feel you want.
- Smart Technology: Modern saunas come with Wi-Fi controls, allowing you to preheat and manage settings from your phone.
- Adds Value to Your Home: A custom sauna can increase property appeal, especially when paired with a home gym or spa area.
Is a Custom Sauna Worth It?
If you’re looking for the ultimate home upgrade that improves both your health and your home’s value, a custom sauna is well worth the investment. While prefabricated models can be less expensive, they lack the personalized fit, design, and luxury of a sauna built for your space.
Whether you’re planning new construction or a remodel, working with a sauna specialist ensures the project is done right—from design and materials to installation and electrical setup.
Bottom Line: A custom sauna costs between $15,000 and $80,000+, with combo infrared models running about $10,000 more. Your final cost depends on the space, wood selection, and level of customization.
