Sauna and Home Insurance: What You Need to Know
Adding a sauna to your home raises a question most people don't think about until after installation: what does this do to my homeowner's insurance? The good news is that a properly installed sauna rarely creates major insurance issues. But there are things you should know and steps you should take to make sure you're covered.

Does a Sauna Affect Your Home Insurance?
In most cases, adding an outdoor sauna is treated similarly to adding a shed, gazebo, or hot tub. Your insurance company needs to know about it because it changes the value of your property and introduces a potential liability.
Here's what typically happens when you call your insurer:
- Coverage increase - Your policy may need to be updated to include the replacement value of the sauna. Most homeowner's policies include coverage for "other structures" at 10% of your dwelling coverage. If your home is insured for $400,000, you have $40,000 in other-structures coverage - more than enough for a sauna.
- Premium adjustment - Adding a sauna might increase your premium slightly, typically $50 to $200 per year. Some insurers don't adjust the premium at all if the sauna value falls within your existing other-structures coverage.
- Liability review - Your insurer may ask about the sauna's location, heating type, and electrical installation to assess liability risk.

What Insurers Want to Know
When you notify your insurance company (and you should), expect these questions:
- Electric or wood-fired? - Electric saunas are viewed more favorably because there's no open flame. Wood-fired saunas may be subject to additional requirements or slightly higher premiums.
- Was it professionally installed? - Particularly the electrical work. A licensed electrician with a pulled permit and passed inspection gives your insurer confidence that the installation is safe.
- Did you get permits? - This matters more than you think. An unpermitted installation is a red flag. If an unpermitted sauna causes damage, your insurer has grounds to dispute the claim.
- What's it worth? - They need the replacement value to ensure adequate coverage. Have your purchase receipt available.
- Where is it located? - Distance from the house, proximity to fences, and vegetation clearance all factor into risk assessment.
What Home Insurance Covers
A standard homeowner's policy typically covers your sauna in these scenarios:
- Fire - Whether the sauna catches fire or a fire from another source damages it
- Weather damage - Storm damage, hail, falling trees, wind
- Theft or vandalism - If someone damages or steals components
- Liability - If a guest is injured while using your sauna, your liability coverage typically applies
What It Usually Doesn't Cover
- Normal wear and tear - Wood weathering, heater element replacement, and general aging aren't covered
- Flood damage - Standard policies exclude flood damage. If you're in a flood zone, consider separate flood insurance.
- Negligence - If you fail to maintain the sauna and that leads to damage (leaving the heater running unattended, ignoring electrical issues), coverage may be denied
- Unpermitted work - Damage resulting from unpermitted electrical work or code violations may not be covered
Tips to Keep Your Insurance Happy
- Notify your insurer before installation - Don't wait until you need to file a claim to tell them about the sauna. Call them as part of your planning process.
- Get permits and inspections - A passed electrical inspection is your best insurance protection. It documents that the installation was done to code.
- Use a licensed electrician - DIY electrical work on a 240V circuit is both dangerous and an insurance liability. Hire a licensed professional.
- Keep documentation - Save your purchase receipt, installation records, permit copies, and inspection reports. You'll need these if you ever file a claim.
- Maintain the sauna - Follow the manufacturer's maintenance recommendations. A well-maintained sauna is a lower risk than a neglected one.
- Install smoke or heat detection - While not always required, placing a heat detector near an outdoor sauna (standard smoke detectors don't work well in sauna environments) shows your insurer you take safety seriously.
Does a Sauna Increase Home Value?
This is related to insurance because your property's value affects your coverage needs. A quality outdoor sauna can increase your home's appeal and potentially its value, particularly in markets where wellness amenities are desirable. However, sauna value doesn't typically get a dollar-for-dollar return on your home appraisal - it's more of an attraction factor that helps your home sell faster or at a higher price in a competitive market.
From an insurance perspective, even if the sauna doesn't dramatically increase your home's appraised value, it still needs to be covered for its replacement cost as a separate structure.
Wood-Fired Saunas and Insurance
Wood-fired saunas get more scrutiny from insurers. Some things that help with approval:
- UL-listed or equivalent certified chimney and stove
- Proper chimney clearance from combustible surfaces
- Spark arrestor installed on the chimney cap
- Adequate clearance from structures, fences, and vegetation
- Following all manufacturer installation guidelines
Some insurers in wildfire-prone areas may decline to cover wood-fired saunas or charge significantly higher premiums. Check with your insurer early if you're considering a wood-burning model.
The Simple Approach
Call your insurance company, tell them what you're planning, ask what they need from you, and follow their guidance. It's usually a 10-minute conversation that prevents potentially enormous headaches later. Then go enjoy your sauna knowing you're fully covered.
