Does a Sauna Increase Home Value? What to Know Before You Sell

Does a sauna add value to a home, or is it a costly feature that will not move a buyer's decision at all? We built My Sauna Plus on a simple premise. We do not simply sell you a sauna. We help you understand saunas and confidently choose the right one. That means giving a straight answer here too, even when the honest answer is more complicated than a single percentage.

Does a Sauna Increase Home Value?

A sauna does not increase home value in any way a national report currently measures. No major resale-value study tracks a sauna as its own category. No national data source can give you a verified recoup percentage for a sauna, the way one exists for a kitchen or a roof.

• The 2025 Cost vs. Value Report, the industry's standard annual benchmark for resale recoup, tracks 28 separate home improvement categories. Sauna, spa, and hot tub are not among them.
• The 2025 Remodeling Impact Report from the National Association of Realtors tracks cost recovery and homeowner satisfaction across dozens of projects. It also has no sauna-specific entry.

The table below shows where tracked projects fall, for comparison.

How Do Appraisers Value an Addition Like a Sauna?

Appraisers value what a sauna contributes to the sale price, not what it cost to build. This is called contributory market value. It is a different number than the receipt in your file.

Colorado's own assessor training manual describes it directly: adjustments for a physical feature must reflect its contributory market value at the time of sale, not the cost of adding it.

A sauna that costs $4,500 to install, the national average, does not automatically add $4,500 to your sale price. It becomes whatever a buyer in your specific market is willing to pay more for, which can be more, less, or nothing at all.

Does It Matter Whether the Sauna Is Indoor or Outdoor?

Placement can matter, based on a general home-improvement pattern rather than a sauna-specific study. Exterior additions tend to outperform interior conversions in resale terms, according to the same Cost vs. Value Report cited above.

This reflects a general home-improvement pattern rather than a sauna-specific finding. Treat it as a reasonable planning assumption rather than a promise. Our Outdoor Saunas collection is a reasonable starting point if resale flexibility matters to you as much as the sauna itself.

What Does a Sauna Cost to Install?

A home sauna typically costs between $3,000 and $6,000 installed, with a national average around $4,500. Costs vary meaningfully by type.

That range matters because it sets the bar the resale question has to clear. If you want the lower end of that range without sacrificing build quality, our guide on what a DIY sauna kit really costs breaks down where the savings actually come from.

Does Installing a Sauna Affect Your Taxes When You Sell?

Yes, a sauna affects your taxes in a straightforward and favorable way. A sauna counts as a home improvement. Home improvements add to your home's adjusted cost basis, the figure used to calculate your taxable gain when you sell.

The IRS states it plainly: additions and improvements add to the value of your home or prolong its useful life. You add their cost to your home's cost basis.

A higher cost basis can reduce your taxable gain when you eventually sell. This counts as a quantifiable financial benefit, distinct from resale value in the marketing sense. Most sauna owners never think to ask about it.

Will a Sauna Affect Your Homeowners Insurance?

A sauna can affect your homeowners insurance policy. Report it to your insurer rather than guess.

Licensed insurance guidance recommends reporting a new sauna to your insurer, for two reasons. First, it ensures the sauna's value is covered under your policy. Second, a sauna can be treated as an attractive nuisance, a legal term for a feature that could attract, and injure, someone without permission.

Neither of these determines whether a sauna adds resale value. Both are simply part of owning a sauna responsibly. Skipping them can cost more than the sauna itself.

Will a Sauna Affect Your Property Taxes?

A sauna can also affect your property tax assessment. Check with your local assessor rather than assume it will not count.

The national standard assessors are trained on says they should collect data on significant detached structures on a property, but it sets no specific formula for valuing something like a sauna. Assessment practice simply varies by jurisdiction.

Contacting your local assessor's office directly is more reliable than any national estimate.

Is Wellness Real Estate a Real, Measurable Trend?

It is real, and growing quickly. Homes built or marketed around wellness features are no longer a niche curiosity. They now make up a measurable, expanding category.

The global wellness real estate market reached $876 billion in 2025, up from $711 billion the year before, and is forecast to reach $1.8 trillion by 2030. That sits inside a larger shift: the global wellness economy overall reached $6.8 trillion, forecast to reach $9.8 trillion by 2029.

None of this guarantees your specific sauna adds resale value in your specific market. It does mean the appetite for wellness-oriented homes is growing. That is worth factoring into your decision.

What Is the Real Return on a Home Sauna?

The most reliable return is how much you use it, not what it adds to a future sale price. It is the most honest answer the data supports, even without a single clean percentage attached.

The Remodeling Impact Report tracks satisfaction and cost recovery separately, and its top projects in each category do not overlap.

Satisfaction and cost recovery are already documented as two separate things, even for the projects that are tracked. The home sauna category itself is growing, independent of resale math. According to Grand View Research, North America holds roughly 28% of global sauna market revenue, and the US segment is projected at a 5.4% annual growth rate through 2033.

If daily use, rather than a future closing statement, is why you are considering a sauna, that changes what you should be shopping for. Our Saunas collection is built around exactly that question. Our Buyer's Guide walks through selection criteria without treating resale value as the reason to buy one. We do not simply sell you a sauna. We help you understand saunas and confidently choose the right one. That includes telling you plainly when a resale expectation does not hold up.

How Do You Choose the Right Sauna If Resale Is Not the Point?

Start with how you and your household will actually use it. Size and budget the sauna around that answer. In our experience, fit and usage pattern matter more to long-term satisfaction than any resale assumption does.

Two resources from My Sauna Plus can help. What Size Sauna Do You Actually Need? walks through capacity planning. It helps you avoid buying a sauna that is too small or too large for your household. Sauna Consultation Questions Every Buyer Should Ask gives you a framework for the decision itself, whether or not you ever book a consultation with us.

Think of a sauna as a lifestyle investment rather than a future down payment. It can still be one of the better decisions you make for your home, provided you understand exactly what kind of return to expect.
