Owners ask us this before they’ve even decided to buy, and it’s a fair question. We install and maintain a lot of holiday-let hot tubs across Cornwall and Devon, so here’s what we actually see, not a sales pitch for why you should buy one.
The honest answer: it depends on the property
A hot tub added to a well-located, well-presented cottage genuinely does make a difference. It shows up in the search filters most major booking platforms offer, it gives you stronger listing photos, and it gives guests something specific to look forward to that a generic garden doesn’t. Added to a property that’s already struggling on location, presentation or price, a hot tub won’t fix those underlying problems on its own.
Where it makes the biggest difference
The clearest impact we see is outside peak summer, when a heated hot tub gives guests a reason to book a coastal cottage in a spot like Newquay, St Ives or Bude in October or February that they wouldn’t otherwise consider. Properties without a hot tub tend to see the sharpest drop-off in shoulder-season bookings. Ones with a hot tub hold up noticeably better through those quieter months.
What it won’t do
It won’t rescue a listing with poor reviews, bad photos generally, or a location nobody wants to visit. And it needs to actually work when guests arrive. A broken or poorly maintained hot tub does more damage to your reviews than not having one at all. A few bad reviews mentioning a faulty hot tub will cost you more bookings than the hot tub itself ever brought in.
What actually matters once it’s installed
Reliability, cleanliness, and clear instructions for guests. Most complaints we hear about holiday-let hot tubs aren’t about the hot tub itself, they’re about it not being ready when guests arrived, or not being clear how to use it safely. That’s a maintenance and process problem, not a product problem, and it’s solvable with a proper servicing routine built around your changeover schedule.
Is it worth the ongoing cost?
For most owners we work with, yes, provided the property is otherwise sound and the hot tub is properly maintained rather than an afterthought. It’s an ongoing cost, not a one-off purchase, and it should be budgeted as part of running the property, not treated as free once it’s installed.
The safety and compliance side you cannot skip
A hot tub in a let is treated differently from one in your own back garden, because you have paying guests using it. That brings health and safety duties around water quality, and the guidance most owners come across is HSG282, which covers managing the risk of legionella in spa-pool systems. You stay ultimately responsible for the property, but you do not have to handle the technical side alone. We carry out the testing, keep the records and give you clear advice, working alongside a specialist partner where deeper legionella work is needed, so you can show you have taken it seriously if you are ever asked. Getting this right protects your guests first and protects you second.
Getting a let-ready hot tub actually ready
A tub that helps bookings is one that is genuinely set up for guests, not just plumbed in. That usually means simple, clear instructions left in the property, a sensible temperature set, and a routine so the water is fresh and balanced for each arrival rather than left over from the last group. It is worth thinking about a lockable cover, quiet hours if neighbours are close, and being clear in your listing about who the tub is suitable for. The owners who get the most out of a hot tub are the ones who treat it as part of the guest experience and plan the practical details in advance.
Budgeting it into the property properly
Treat the hot tub as a running cost from day one. There is the electricity to keep it warm, the water care and filters, the changeover cleaning between guests, and periodic servicing to keep it reliable. Set against that is the higher nightly rate a hot tub usually supports and the extra bookings in the quieter months. For most sound properties the numbers work, but they work best when the upkeep is budgeted for rather than being a surprise each quarter. We are happy to talk through what the ongoing side realistically involves before you commit.
The property types that gain the most
From what we see across Cornwall and Devon, the biggest lift tends to go to couples’ boltholes and smaller cottages aimed at romantic or off-season breaks, where a hot tub with a sea view or a quiet garden becomes the reason to book. Larger family properties benefit too, especially for wet-weather weeks when there is not much else to do. The ones that gain least are properties competing purely on being the cheapest option, where guests are not really paying for extras. If you are not sure which camp yours falls into, tell us about it and we will give you a straight view.
Frequently asked questions
Do I legally have to do anything special for a hot tub in a holiday let?
You have a duty to manage the water safely for guests, which is where HSG282 and a proper testing and record-keeping routine come in. You do not need to become an expert yourself. We can handle the testing and records and advise you on the rest, so the tub stays safe and you have evidence you have looked after it.
Do guests actually search for hot tubs?
They do. On the main booking platforms a hot tub is one of the filters people use, so having one can put your property in front of guests who would never have seen it otherwise. It also gives you a stronger headline photo and something concrete to feature in the listing text, which matters most in the crowded shoulder-season market.
Should I turn the tub off between bookings to save money?
Usually not. Repeatedly heating a tub from cold uses more energy than holding it at a steady temperature, and cold, standing water brings its own hygiene problems. It is normally better to keep it running and managed properly, and to find savings through a good cover and correct water care instead.
How much upkeep does a let hot tub really need?
More than a private one, because a fresh set of guests each week means a structured routine of cleaning, testing and changeover care, plus regular servicing. How often depends on how busy the property is. We build a schedule around your changeover days so the tub is ready for every arrival.
Can you manage all of this for me?
Yes. Plenty of owners hand the whole tub side to us through our holiday-let management, from changeover cleans to servicing and compliance testing, so it runs in the background while they get on with letting the property. Nick and Ryan cover Cornwall and Devon between them.
Thinking about adding one?
Tell us about your property, roughly what it’s currently achieving in bookings, and what time of year you’re weakest, and we’ll give you an honest view on whether a hot tub is likely to help.
