Why Holiday Let Hot Tubs Are Different
A hot tub in your own garden gets used by the same family, a few times a week, with consistent water care. A holiday let hot tub gets used by different people every week, with varying hygiene, different body products, and no guarantee that anyone read the instructions. It heats up, cools down, drains, refills, and does it all again seven days later.
That is a fundamentally different job. The tub you choose needs to handle it.
Devon and Somerset Trading Standards say it plainly: cheap inflatable or home-use hot tubs are not suitable for commercial or business use. If you buy a domestic tub for a holiday let, expect problems within 18 months. Cracked shells, failed pumps, corroded frames, and guests arriving to a broken tub on a Friday evening.
What “Commercial Grade” Actually Means
Steel frame construction
Domestic tubs often use wooden frames. Wood rots, especially in the damp conditions underneath a constantly filled hot tub. Commercial-grade tubs use galvanised steel frames. They do not rot, warp, or weaken over time. Both the ReefSpa Coral and Ocean use steel frames as standard.
24/7 filtration
HSG282 recommends that domestic-type hot tubs used in business settings should be capable of circulating and filtering the total water volume within 15 minutes. Both the Coral and Ocean meet this standard. Cheaper tubs often take 30-60 minutes for a full turnover, which means bacteria have more time to multiply between filtration cycles.
Inline chemical feeders
HSG282 specifies that business-use hot tubs should use inline chemical feeders rather than hand-dosing. An inline feeder continuously maintains disinfectant levels. Hand-dosing means someone has to physically add chemicals, and if they forget or get the dose wrong, water quality drops. The Coral and Ocean both come with inline feeders fitted.
Durable covers
Guests treat covers roughly. They drag them, drop them, sit on them, and leave them open overnight. A flimsy cover will crack, waterlog, and lose insulation within a season. A good holiday let tub comes with a reinforced cover and ideally a cover lifter that makes it easy for guests to use properly.
13A Plug-and-Play vs 32A Hardwired
Larger domestic hot tubs need a dedicated 32A electrical supply installed by a registered electrician. That adds cost, disruption, and a certificate to manage.
The Coral and Ocean both run on a standard 13A household plug. You fill it, plug it in, and it works. No electrician, no dedicated circuit, no sign-off. For a holiday let owner, that is a significant advantage: lower install cost, simpler setup, and one less contractor to coordinate.
The trade-off is heat-up time. A 13A tub heats more slowly than a 32A one. But since the tub runs 24/7 and maintains temperature constantly, this only matters on the initial fill. After that, you are just maintaining temperature, which a 13A supply handles comfortably.
Bather Capacity: Match the Property
BISHTA guidance recommends that the hot tub capacity should match the sleeping capacity of the property. If your cottage sleeps six, a four-seater tub means guests will overload it. Overloading strains the filtration system, drops water quality, and creates hygiene risks.
- ReefSpa Coral (4 seats, 29 jets, from £5,995): Best for properties sleeping 2-4 guests. Couples cottages, shepherd’s huts, small lets.
- ReefSpa Ocean (6 seats, 40 jets, from £6,495): Best for properties sleeping 4-6 guests. Family cottages, lodges, larger lets.
Both are ReefSpa models, 2026 WhatSpa? Approved, with Balboa controls, HeatSave2 insulation, and Pulsar jets.
Guest-Lockable Controls
Guests will change the temperature if they can. They will turn off the filtration if they find the button. They will experiment with every setting. Balboa controls on both ReefSpa holiday let models allow you to lock key settings so guests can adjust jets and lighting but cannot change temperature limits or disable filtration.
What to Avoid
Inflatable or soft-sided tubs
They are cheap. They are also fragile, poorly insulated, have weak filtration, and cannot be fitted with inline chemical feeders. They do not meet HSG282 standards for business use. A guest with a sharp toenail or a dropped glass can puncture one in seconds.
Internet bargains with no local support
When a tub breaks down on a Friday afternoon with guests checking in at four, you need someone who will answer the phone. An online retailer 200 miles away will not send an engineer by morning. A local dealer with a service contract will. We offer priority callout for holiday let customers for exactly this reason.
Oversized tubs
Bigger is not better for holiday lets. A larger tub means more water to heat (higher running costs), more chemicals per dose, longer drain and refill times at changeover, and more weight on the base. Choose the right size for the property, not the biggest one available.
Running Costs
A well-insulated 13A holiday let tub typically costs £30-50 per month to run on electricity, depending on usage and ambient temperature. Chemical costs run around £15-25 per month. Annual servicing is roughly £150-200. Lab testing for HSG282 compliance adds around £30-50 per month.
Total ongoing cost: roughly £100-150 per month. Against a nightly rate uplift of £30-50 per night and improved occupancy, the return is strong.
Our Recommendation
For most Hampshire holiday lets, we recommend the ReefSpa Coral for smaller properties and the ReefSpa Ocean for family lets. Both are commercial-grade, HSG282-suitable, 13A plug-and-play, and backed by our full holiday let service package.
