Search for a cheap hot tub and most of what comes back costs £350 or more. When we went through Amazon UK in October 2026, only two heated inflatable hot tubs were genuinely at or below £300: the Lay-Z-Spa Cancun AirJet and the Nordivale 208cm inflatable hot tub. Both are on this page. Everything else in the search sat between about £350 and £400, which is why our under-£400 page has more to choose from.
Below £300 the results change. What Amazon shows under "inflatable hot tub" at £10-£60 are inflatable bathtubs and soaking tubs: no heater, no pump, no filter. They hold warm water from the tap and that's it. Covers, liners, chemical kits and floor protectors fill the rest of the cheap results. So the realistic floor for a heated hot tub in the UK right now is a little over £250.
That small choice isn't a problem if you know what to look for. The budget hot tub market moves fast - Lay-Z-Spa models often drop into this band in sales, and new own-brand tubs appear every month - so we check prices every time we update this page and add any tub that fits.
Every figure below comes from the hot tub's own listing or the manufacturer. We don't print exact prices because Amazon changes them daily; both were £300 or less when we checked.

In short: the Cancun is the safer buy with a known brand, a warranty and a long review history. The Nordivale gives you a much bigger tub for less money, with less track record behind it.
The Cancun is the cheapest current Lay-Z-Spa hot tub we can find, and the one most often recommended as a starter hot tub. Hot tub engineer John Devlin, quoted in the Telegraph's inflatable hot tub guide, recommends it as a good budget option for its wicker-effect look and low price. This hot tub is square, 180cm each side and 66cm high, holds 669 litres and seats 2-4 people. A square tub gives everyone a side to lean on and tucks into the corner of a patio.
It has the same pump features as Lay-Z-Spa's dearer tubs: 120 AirJets round the floor, Freeze Shield so it can run through a UK winter, a built-in RCD, ground detection and a power-saving timer that lets you have it hot for when you get home. Its spec sheet gives 5 minutes to inflate, about 2.5 hours to fill and around 12 hours to heat from cold to 40°C. An insulating cover, a ChemConnect chlorine dispenser and a repair patch are included, and it carries Lay-Z-Spa's 2-year manufacturer's warranty.
The Nordivale is an own-brand hot tub and the cheapest heated hot tub we found on Amazon UK. For that you get a 208cm round tub, 65cm high, that Nordivale rates for 4-6 adults - a family-size spa for less than the price of most 2-4 person tubs. An 1800W heater and filter pump run on a normal 220-240V socket, 130 air jets give a bubble massage and a GFCI plug cuts the power if there's a fault.
The kit is generous: an insulated cover, a ground sheet, four filter cartridges, two filter covers and an inflation hose. The outer wall is 0.66mm PVC with a reinforced mesh layer. The trade-off is track record. It has 60 ratings at 3.8 stars rather than thousands, and the listing doesn't state the water capacity or a warranty, so read the most recent reviews first. The listing also suggests using it in a bathroom; a 208cm tub full of water is very heavy, so it belongs on a patio or level lawn unless a builder has checked your floor.
A hot tub under £300 heats to the same temperature and bubbles the same way as one at £400. Both tubs here reach a comfortable 38-40°C and both come with an insulated cover. Where they save money is elsewhere:
What you don't give up is safety. Both tubs have a residual-current device (an RCD on the Cancun, a GFCI plug on the Nordivale), which is the important one with water and mains power. Spending the extra £50-£100 for the under-£400 band mostly buys choice: rattan-effect walls, app control and more 2-4 person round tubs with thousands of reviews.
A cheap hot tub isn't cheap to run if you leave the lid off. The heater is the big cost, and you can work it out from its power. Under Ofgem's price cap for 1 October to 31 December 2026, electricity costs 26.32p per kWh on a standard Direct Debit tariff (VAT has been taken off electricity bills until March 2027). So:
Once the hot tub is up to temperature, the heater only tops the water up. How often depends on the weather and the cover. As an example, if the heater runs four hours a day to hold temperature in autumn, that is about £2.20 a day, or £15 a week, for the Cancun. That is in line with the Telegraph's research, which found most users of inflatable spas see their bills rise by about £12-£15 a week.
To keep it down: fill with warm water if you can, keep the cover clipped on, use the timer to heat only before you soak, and put the hot tub on an insulating mat rather than cold paving. Draining it over the coldest months is often cheaper than keeping a budget tub hot all winter.
The hot tub itself is the main spend, but budget for a few things it needs on day one:
Clean water matters as much in a cheap hot tub as an expensive one. Warm, still water is where bacteria grow, and the NHS lists hot tubs as one source of Legionnaires' disease. Test the water before each use, keep the sanitiser level right and change the water every few months.
With so few heated tubs under £300, the bigger risk is buying the wrong thing from the wider search results. Check these on any budget listing:
Shape is a matter of taste: a square hot tub fits a corner, while the round inflatable hot tubs page has more choice in the next price bands up. If looks matter, see the wood effect inflatable hot tubs, though none of those is under £300 at the moment.
A lot of people searching for a cheap Lazy Spa want a Lay-Z-Spa (often spelt "Lazy Spa"), the Bestway brand that a hot tub engineer quoted by the Telegraph calls the most popular inflatable hot tub brand. The Cancun is the only current Lay-Z-Spa we found at or under £300. Pick it if you want a known brand: Lay-Z-Spa has a UK support team, its filters and spare parts are widely sold, and the pump has Freeze Shield for winter.
Unbranded budget hot tubs like the Nordivale undercut it with more space and more in the box. They make sense if you want room for four or more adults on a small budget and are happy to rely on Amazon's returns if something goes wrong. Many of these listings call themselves a "lazy spa" too, so check the brand name, not the title.
Lay-Z-Spa tubs drop under £300 from time to time, usually in sales. The Cancun was well below its usual list price when we checked. If the model you want is just over budget, it can be worth waiting - we update this page as prices change.
Yes, but only a few. When we checked Amazon UK in October 2026, the Lay-Z-Spa Cancun and the Nordivale 208cm were the only heated inflatable hot tubs at or under £300. Most others started at about £350.
Not a heated one that we could find. Under £200 you get inflatable bathtubs and soaking tubs with no heater or pump, plus covers and liners for existing tubs. For a tub that heats to 40°C, budget a little over £250.
They heat and bubble just like dearer tubs. Savings come from slower heating, fewer extras and, on own-brand tubs, less review history and harder-to-find parts. A budget Lay-Z-Spa with a 2-year warranty is the lower-risk choice.
At the October-December 2026 price cap (26.32p per kWh), the Cancun's heater costs about 54p an hour and the Nordivale's about 47p. With the cover on, regular use usually comes to around £12-£15 a week.
The Cancun has Freeze Shield in its pump for cold weather. The Nordivale listing doesn't mention frost protection. In either case winter use costs more, so keep the cover on, use an insulating ground mat, or drain the tub for the coldest months.
It depends more on care than price: keep the water balanced, the filters clean, the cover on and the tub off sharp ground. The Cancun's 2-year manufacturer's warranty covers the early years; the Nordivale listing doesn't state one.
