Is a hot tub worth it for your Airbnb?

When is a hot tub a sensible investment?

A good hot tub can help a holiday let compete for a different kind of stay. Couples may be looking for a weekend together rather than the cheapest place to sleep. A group may choose a house where it can spend the evening rather than pay to go out. In a city, a private outdoor space with a properly presented hot tub can be much rarer than it is among rural holiday cottages.

That is a reason to investigate a premium, not a reason to assume one. A guest still needs a comfortable home, a convincing location and a whole stay price that makes sense. An uncomfortable bed with an expensive tub outside is still an uncomfortable bed. Fix the essentials in our guide to Airbnb amenities before spending on a luxury extra.

The strongest case is a property that can charge more for nights it already sells, fill genuinely additional dates and operate the tub reliably. The weakest case relies on a large occupancy jump, ignores cleaning time or only works if nothing breaks. Neither a supplier’s revenue claim nor a competitor’s asking price is your return on investment.

Our practical experience is that the appeal can be real, particularly where the feature is unusual locally. The less visible part is the work. A drain, clean and refill is not a quick wipe around the rim. A fault on a Friday afternoon is not conveniently timed for a service engineer. Those are costs of selling the amenity, not reasons to leave it out of the budget.

What does an extra £50 a night actually leave you?

Take a holiday let selling 180 nights a year at £150 a night. Its annual room income is £27,000. In this worked example, adding a hot tub raises the rate to £200, but five paid nights are lost to downtime. That leaves 175 paid nights and £35,000 in room income.

The extra room income is £8,000. If you keep 80% after booking and management deductions, £6,400 remains before the tub’s running costs. Using the calculator’s annual budget of £4,928 leaves about £1,472 a year before finance, depreciation and tax. On a £9,500 installation, that gives a simple payback of about 6.5 years.

The rate makes a substantial difference. Keep the same costs and downtime but achieve only £35 extra a night, and the tub leaves you about £628 worse off each year. At £75 extra, annual contribution rises to about £4,972 and simple payback falls to 1.9 years. None of these examples assumes that the tub creates additional bookings.

Before buying, test the full trip price against similar homes for the dates and guests you want to attract. Compare the outdoor space and privacy as well as the bedrooms and location. Then put your own quotes and expected premium into the calculator. If the return only works at a rate comparable guests will not pay, choose a different improvement.

A central flat and a secluded cottage sell different things

In a rural holiday market, a hot tub may be common enough that its absence puts a property out of consideration. In a city, it may make a listing more distinctive. Neither setting automatically produces a larger return. Search for comparable homes for the same dates, guest count and length of stay, then look at the final trip price and the actual quality of the outdoor space.

Privacy, outlook, access and noise often decide whether the promise holds up. A tub beside a neighbour’s bedroom is a different product from one in a sheltered private garden. Guests may not pay much extra for a feature they feel awkward using. City scarcity is not a reason to ignore other residents. Our guide to Airbnb neighbour complaints explains how to separate genuine nuisance from disagreement about short letting.

For a balcony, roof terrace or upper floor, stop the purchase discussion until the loading, waterproofing, drainage and route for installation have been assessed by appropriate professionals. The filled tub, occupants and equipment impose a very different load from empty furniture. Do not use a supplier’s empty weight as a structural assessment.

The running costs go well beyond the electricity

Buy the installation, not just the tub

The purchase price is only part of the capital cost. Get a written quote for delivery, access equipment, a suitable base or structural work, electrical supply, drainage arrangements, cover, steps and any screening. Include the safety assessment, initial training and the work needed to make access safe. Check whether VAT is included and whether you can actually reclaim it.

A cheaper model can become expensive if it takes too long to empty, clean, refill and return to a usable temperature between guests. Confirm that it is suitable for the intended business use, that its warranty covers that use and that service parts are available. A low purchase price does not make an unsuitable setup safe.

Meter the electricity through the whole operating cycle

Do not multiply the heater’s rating by a guessed number of hours. Measure consumption over representative occupied and empty days, including refills and reheating. Air temperature, insulation, cover condition, wind, water temperature and guest behaviour all affect consumption. A warm week is not a winter running cost.

Use your actual tariff and count days the system stays powered when nobody is paying to use it. Have any submeter or monitoring equipment installed appropriately. The calculator starts at 12 kWh a day as an example. Replace that figure with consumption for your equipment and operating conditions, including refill heating.

Pay for the cleaner’s time and the water

Agree exactly who empties, cleans, refills, tests and records the work, and how that fits the arrival window. Count paid labour, travel and supervision rather than assuming the existing cleaner will absorb it. If a changeover becomes longer, the cost may include another person or an earlier departure and later arrival.

Water costs depend on refill volume, frequency and your metered water and sewerage charges. The safe operating procedure decides the frequency, not the spreadsheet. Top ups, backwashing and exceptional contamination can add to the volume. The calculator lets you edit refills separately from guest changeovers because those counts need not be identical.

Budget for tests, treatment and things that fail

Allow for chemicals, filters, testing equipment, laboratory sampling where appropriate, staff training and record keeping. Include additional insurance, professional assessment and servicing. A maintenance reserve is money set aside for likely future work, not proof that the repair bill will arrive evenly each year.

Heaters, pumps, covers, jets and controls can fail. A specialist callout may cost more when the next guest is hours away. Keep room in the budget for downtime, an alternative arrangement or an appropriate refund when a prominent advertised amenity cannot be provided. Read your booking terms and the platform’s current rules rather than assuming a small disclaimer removes that exposure.

Check the margin before you buy

The calculator starts with a £35 nightly premium and no additional bookings. Under that budget, higher room income still leaves £628 less each year after running costs. Change the premium to £50 and the annual contribution becomes about £1,472. Then try a winter electricity reading, a longer changeover or more downtime to see how much room there is for a bad month. A worthwhile investment should leave enough margin to repay the installation as well as pay the regular bills.

Look at the return on the whole installed cost, not just whether a year’s running bills are covered. A ten year simple payback is not a guarantee that the equipment will last ten years. You may prefer to spend on insulation, beds, soundproofing, a useful work space or photography. Those choices have different costs and may suit the guests the property already attracts.

A seasonal benefit also needs a seasonal budget. A tub may make a cold weather stay more appealing, but a quiet week still has standing work and energy costs. Our guide to earning more in low season looks at demand, minimum stays and booking contribution. Use the winter cashflow comparison for the wider decision between short stays and a residential tenancy.

Who will keep the water safe?

A hot tub is not made safe by clear looking water, a signed guest disclaimer or a cleaner who knows how a domestic tub works. Warm water, aerosol generation and changing users create risks that need a suitable assessment and a competent operating regime. Infection is not the only concern. Slips, drowning, electrical hazards, chemical handling and access by children also need attention.

The Health and Safety Executive’s HSG282 guidance on spa pool systems distinguishes a domestic type tub supplied to one discrete holiday group from a commercial spa with a higher or shared bather load. A domestic type system used in business still needs appropriate controls. The guidance is the 2017 edition, not a new hot tub law introduced in 2026.

Its Table 1 gives typical inspection and monitoring frequencies, with the risk assessment determining the regime. For domestic type systems it includes at least twice daily water clarity and pH and disinfectant checks according to risk and use. It also describes draining and cleaning between groups or weekly if sooner, general microbiological sampling monthly and legionella sampling quarterly. Read the full context on printed pages 34 and 35 of HSG282 with a competent specialist. These are operating commitments to cost, not a complete procedure to copy from an article.

Establish who is competent to carry out the work, how results and corrective action are recorded, who provides absence cover and when the system must close. A guest instruction card helps people use a safe facility. It does not replace supplying one. Remote sensors may help spot a fault sooner, but they do not themselves establish safe water or remove the need for the operating regime.

If the water or equipment fails the operating limits, stop use and follow the corrective procedure. Do not keep an unsafe tub open because the guest paid for it. If illness is reported after use, preserve the relevant operating records and discuss the report with the local environmental health officer, insurer and appropriate professionals. Do not diagnose the cause, automatically admit responsibility or dismiss it.

Insurance and responsibility need to match the real use

Tell your insurer what the property is used for, how the tub is supplied and who operates it. Ask about guest use, public liability, accidental and water damage, maintenance conditions and exclusions. Get the answer in writing. A standard home policy or platform protection is not proof that a commercial hot tub claim is covered.

Guest rules do not replace safe operation. For consumer services within its scope, section 65 of the Consumer Rights Act prevents excluding liability for death or personal injury caused by negligence. It does not make every illness the operator’s fault, and its application to a particular contract needs proper advice. Do not rely on a use at your own risk sign to settle the issue.

In Scotland, check the short let licensing guidance and additional local licence conditions as well as planning and equipment safety. In Northern Ireland, check with HSENI and the council rather than assuming the Great Britain legislation or England’s property rules apply. If a manager or contractor takes on the work, define access, records, cover and escalation. Paying somebody does not automatically remove the owner’s duties.

What if it is a conventional rental rather than an Airbnb?

A tenant looking for a home is not buying a weekend experience. A hot tub may appeal to some applicants, but the nightly premium model does not translate into an automatic rent increase. Compare realistic monthly rent, the tenancy arrangement, responsibilities, repairs and the likely time someone will stay.

Decide whether the tub forms part of what you supply, who can access it, who checks and services it and who pays for power and repairs. Do not assume a tenancy clause cancels statutory duties. The HSE’s landlord guidance on legionella explains ordinary domestic water systems. Its usual low risk approach and usual lack of sampling are not a hot tub exemption.

A tenant’s own installation is a different arrangement and still raises permission, lease, insurer and safety questions. For a tub already on site, compare retaining it, professionally decommissioning it or excluding it safely from the let. Get appropriate advice rather than leaving an unusable amenity with a vague promise. A feature that attracts one tenant can become a recurring dispute if nobody has agreed how it is run.

Get the answers before the delivery date

Have the permissions, structure, electrics, drainage and neighbour impact checked before paying a deposit you cannot recover. A lease, insurer, lender, planning position or licensing condition can affect the project. Our guide to whether you can Airbnb your property covers the wider permission questions, not automatic consent for a hot tub.

Ask the supplier and operator to walk through a real departure and arrival. Time the work, include refill and reheating, and explain what happens when the usual person is unavailable. If a safe turnaround does not fit the promised arrival time, change the operation or the promise before accepting bookings.

Record current performance before installation so you have a fair baseline. Save room revenue, paid nights, the available calendar, pricing changes and bills. Review the same measures afterwards through comparable seasons. Do not judge success from the first busy weekend or a few reviews mentioning the tub.
