Should You Add a Sauna to Your Vacation Rental or Airbnb?

Q: How should I promote the sauna?

Show it accurately in the photo tour, select the correct amenity, describe access and privacy, and put essential rules in the listing and arrival guide. Avoid medical promises and vague luxury language. Tell guests what the experience actually is.

A sauna can make a vacation rental memorable, but it is not an automatic revenue win. Use this practical test for demand, design, safety, operations, and payback.

Short answer: Add a sauna when it fits the property, the guest, and your operating system. The numbers also need to work after installation, cleaning, energy, service, insurance, and downtime. Do not add one because someone promised it would pay for itself. There is no trustworthy universal return-on-investment number for a vacation-rental sauna.

Updated August 2026: This guide is for owners and managers evaluating a real project. It is not a building plan, code opinion, insurance opinion, or earnings forecast.

When a sauna is a strong fit

A sauna is most convincing when it completes an experience that already makes sense: a ski cabin, lakeside retreat, cold-weather escape, wellness stay, or design-led property where guests have time and privacy to use it. It is less convincing when the site has no safe location, the turnover team cannot inspect it, local rules are unclear, or guests would struggle to operate it.

Start with your own market. Review properties that closely match yours, read guest reviews, and ask past guests whether a sauna would affect their choice, not merely whether they like saunas. Airbnb says guests use amenity filters and advises hosts to list every amenity they actually offer, but the ten most-searched amenities in its worldwide 2024 search data, published in August 2025, did not include sauna. That makes a sauna a property-specific differentiator, not proof of universal demand. See Airbnb’s current amenities guidance .

Use this five-part go or no-go test

1. Demand: will the right guests notice?

Is sauna consistent with the trip guests are already booking?

Do close competitors offer one, and what do their recent reviews actually say about it?

Can you photograph the room honestly and explain whether it is private, shared, indoor, outdoor, electric, or wood-fired?

Would it still be valuable outside the property’s peak season?

A “yes” here earns more investigation. It does not establish a higher nightly rate.

2. Feasibility: can you approve and insure the exact installation?

Before choosing a kit, give the local building department, fire authority where relevant, electrician or chimney professional, short-term-rental regulator, and insurer a concrete scope. Include the site, foundation, structure, heater model, power or fuel, ventilation, drainage, clearances, guard, controls, and intended guest use. Ask what permits, inspections, listings or certifications, and operating restrictions apply.

Use the exact manufacturer manual. Harvia, for example, says heater output must match room volume and installation must follow model-specific safety distances; its current ventilation guidance also warns that supply-air placement must not interfere with the heater’s temperature sensor. Those are useful design principles, not a substitute for the manual or local approval. See Harvia’s sauna ventilation guidance and wood-heater installation overview .

3. Guest design: can a first-time bather use it correctly?

Design the whole guest experience, not just the hot room: a lit and slip-conscious path, a place to change, hooks and towels, privacy, simple controls, a safe cool-down area, and instructions visible before anyone switches on the heater. Clearly state maximum occupancy, what may go on the rocks, whether minors may use the sauna, when not to use it, how to shut it down, and who to contact.

Airbnb recommends accurate amenity details, current safety information, and house rules; Vrbo lets hosts attach instructions to an amenity in the property welcome guide. Use those tools, but also post concise instructions at the sauna because phones and platform messages do not belong in every hot room. Review Airbnb’s host safety guidance and Vrbo’s amenity-instruction guidance .

4. Operations: who owns every reset and repair?

A rental sauna is not maintenance-free. Build a written turnover check for cleanliness, drying, blocked vents, items left near the heater, control function, door and guard condition, visible damage, water supply if applicable, and any sign that the heater or stones need service. Keep the manufacturer’s inspection schedule, service contacts, model and serial numbers, and replacement-part path with the property records.

Decide who takes the sauna out of service, how quickly that person can act, and how you will communicate an unavailable amenity to an arriving guest. If the local cleaner or manager cannot confidently own that process, the amenity is not ready.

5. Economics: does the conservative case work?

Calculate the complete installed cost: design, permits, product, freight, site work, foundation, electrical or chimney work, ventilation, drainage, safety details, furnishings, and contingency. Then model recurring energy, cleaning time, laundry, inspections, insurance changes, consumables, repairs, platform fees on any added revenue, and expected downtime.

A simple break-even check is:

all-in project cost ÷ conservative added monthly contribution = estimated months to recover the investment

“Added contribution” means revenue plausibly attributable to the sauna minus its recurring costs. It does not mean the property’s total revenue. Compare the same seasons before and after launch, track sauna mentions in inquiries and reviews, and resist crediting the sauna for changes caused by pricing, weather, renovations, or market demand. Run a downside case with no rate increase.

Buying is not the only way to test the idea

A mobile-sauna partnership can test demand for a special weekend, retreat, or seasonal package before permanent construction. It only works if a local operator serves the address and all parties agree on access, delivery and pickup, setup, permits, insurance, guest instructions, cleaning, fuel, supervision, cancellation, and weather. Start with the SaunaShare mobile-sauna directory ; availability and terms come from each operator.

Frequently asked questions

Will a sauna increase bookings or nightly rates?

It may help the right property stand out, but there is no general result you can safely apply to your listing. Validate local demand and run the project on conservative numbers.

Is an outdoor sauna better for a vacation rental?

Not automatically. Outdoor placement can create a memorable sequence and avoid taking interior space, but weather exposure, access, lighting, privacy, foundation, utilities, and maintenance all become part of the design.

Is electric or wood-fired easier for guests?

Electric controls can be simpler, while wood heat can be central to the experience. Either can be the wrong choice if the site, local rules, insurer, turnover team, or guest instructions do not support it. Decide from the operating model, then select a compliant heater.
