How a Sauna Increases Home Value: Resale Value Guide
You're thinking about buying a sauna, and part of you wonders: will this add value to my home, or is it just a personal luxury? It's a fair question. You want to enjoy the sauna now, but if you ever sell, it'd be nice to recoup some of that investment.
The short answer: a well-installed sauna can increase your home's appeal and market value, but how much depends on where you live, the quality of the installation, and how the real estate market in your area views wellness amenities.

Does a Sauna Actually Increase Home Value?
There's no universal formula, but here's what the data and real estate professionals consistently say:
- Saunas are a sought-after amenity. Real estate listings with "sauna" consistently get more views and engagement than comparable listings without one. Buyers notice it.
- Homes with wellness features sell faster. In competitive markets, a sauna can differentiate your home from similar properties. It's a talking point that sticks in buyers' minds.
- ROI varies by market. In areas where saunas are common (Nordic communities, Pacific Northwest, mountain towns), a sauna is almost expected in higher-end homes. In markets where saunas are rare, it's a unique feature that stands out.
- Quality matters more than having one. A cheap, poorly installed sauna in a moldy corner of the basement hurts value. A well-built, attractive sauna in a thoughtful location helps it.
Estimated ROI by Sauna Type
| Sauna Type | Installed Cost | Estimated Value Added | Typical ROI |
|---|---|---|---|
| Outdoor barrel sauna | $5,000-$10,000 | $3,000-$8,000 | 50-80% |
| Indoor pre-fab kit sauna | $4,000-$8,000 | $3,000-$6,000 | 50-75% |
| Custom-built sauna room | $8,000-$20,000 | $5,000-$15,000 | 50-75% |
| Infrared sauna cabin | $2,000-$5,000 | $1,000-$3,000 | 40-60% |
These estimates are based on general real estate trends. Actual value depends on your local market, home price point, and buyer preferences.
What Adds the Most Value
Quality of Construction
Buyers can spot cheap construction. A sauna built with quality wood (like FSC-certified heat-treated Canadian hemlock), a premium heater (Harvia or Huum), and proper electrical work says "this was done right." It gives buyers confidence that the sauna is a feature, not a problem waiting to happen.
Professional Installation
A sauna with permitted electrical work, proper ventilation, and a solid foundation shows that the homeowner invested in doing it correctly. Unpermitted electrical work, in particular, is a red flag during home inspections that can reduce value rather than add it.
Aesthetic Appeal
A sauna that looks beautiful - clean lines, quality glass door, attractive wood, good lighting - photographs well for listings and impresses buyers in person. The visual impact matters, especially for the first impression in real estate photos.
Thoughtful Placement
- An outdoor sauna in a landscaped backyard with a path, lighting, and perhaps a cold plunge creates a "wellness retreat" feel that can significantly boost perceived value.
- An indoor sauna near a bathroom (for easy shower access) makes practical sense and adds to the home's flow.
- A sauna that blocks the yard, takes up a parking space, or creates an awkward layout actually detracts from value.
Markets Where Saunas Add the Most Value
- Mountain and resort communities. Ski towns and mountain communities expect wellness amenities. A sauna can be a selling requirement, not just a bonus.
- Nordic-influenced areas. Upper Midwest states (Minnesota, Wisconsin, Michigan) have strong sauna culture. Buyers actively look for homes with saunas.
- Pacific Northwest. The wellness culture in Oregon and Washington makes saunas a valued feature.
- Higher price-point homes ($500K+). The wealthier the market, the more buyers expect amenities like saunas, hot tubs, and fitness spaces.
- Wellness-focused communities. Areas with health-conscious demographics (parts of Colorado, California, Austin TX) value home wellness features.
How to Maximize Resale Value
Keep It Maintained
A sauna that looks worn, has water stains, or smells musty will turn buyers off. Before listing your home:
- Sand and refresh the benches
- Clean the heater and replace stones if needed
- Re-stain the exterior (for outdoor saunas)
- Replace the door gasket if it's worn
- Make sure everything works perfectly
Document the Installation
Keep records of:
- Purchase receipts and warranty information
- Electrical permits and inspection certificates
- Heater model and specifications
- Maintenance records
Buyers and home inspectors love documentation. It proves the work was done properly and makes the sauna a verified feature rather than a question mark.
Stage It Well
When listing your home:
- Clean and stage the sauna with fresh towels, a wooden bucket and ladle, and a thermometer
- Photograph it professionally - interior and exterior shots
- Include the sauna prominently in your listing description
- Mention the brand, heater type, and any premium features
What Detracts from Value
- Unpermitted electrical work. A home inspector will flag this, and buyers may demand it be redone or reduce their offer.
- Poor placement. A sauna blocking the backyard, taking up a garage bay, or in an inconvenient location is viewed as a problem, not a feature.
- Visible deterioration. Rotting wood, broken glass, a non-functional heater, or mold damage turns a selling point into a negotiation chip against you.
- Cheap construction. A flimsy infrared tent or a poorly assembled DIY sauna looks worse than having no sauna at all.
- Removal difficulty. If a buyer doesn't want the sauna, will it be easy to remove? Freestanding and kit saunas have an advantage here since they can be disassembled. A permanent custom build in an odd location is harder to repurpose.
The Bottom Line
A sauna is primarily a lifestyle investment - you buy it for the daily health and relaxation benefits. The resale value is a bonus, not the primary justification. That said, a quality sauna installed properly in the right spot will return 50-80% of its cost at resale while giving you years of use beforehand. That's a better return than most home upgrades when you factor in the personal enjoyment.
