Inflatable hot tub buying guide

Updated: October 2026

You have a spare corner of patio and a shortlist of inflatable hot tubs whose titles do not match their own specification lines. One page says six people and then prints a smaller number. Another quotes gallons and never says imperial or US. A cover is sometimes in the box and sometimes only inside a sentence about saving energy. This inflatable hot tub buying guide is the re-read we use before a row becomes a shortlist. Prices and star lines stay on the [hot tub comparison](/hub/steam-baths/hot-tub). The Products Compared editorial team checked the amazon.co.uk listings, not a lab soak. A qualifying purchase can earn a commission at no extra cost to you.

Read the seat line twice

Advertised seats are a maximum. Hot Tub Geek’s 2026 notes say to leave a spare seat, and not to plan the tub as a full house every evening. The Aruba title says 2–3 and the seating field says 3. The Tekapo title and field both say 6. The EASE.ZONE title says 4–6, the field says 4, and a bullet says up to six. The unnamed Generic is the clearest warning. The title says 4–6, and a bullet on the same listing says 2–3 or 4–6. If you cannot say which line you are buying, you are not buying a size. The best inflatable hot tub page applies the same seat lines to each row.

Litres, gallons and the floor

Water is the weight, not the pump. The EASE.ZONE bullets say up to 910 litres, and a litre of water weighs about a kilogram, so the fill alone is about 910 kg before anyone climbs in. A deck, a balcony or a raised patio is a structural question, not a lifestyle one. Gallons on the other rows are not a substitute for that sum. The Tekapo prints 245 gallons and does not say imperial or US. As a rule of thumb, 245 US gallons is about 930 litres and 245 imperial gallons is about 1,110 litres, so the silence moves the mass by roughly 180 kg. Do not convert the drop-stitch Generic’s 455 gallons or the SENODON’s 299 gallons: neither listing chooses a gallon.

Cover, filter, pump

A cover you can put on is part of the product. A cover that appears only in a saving claim is a spare you may still have to buy. The Aruba lists a pool cover, a Type VI filter, a ChemConnect dispenser and a repair patch. The EASE.ZONE lists a cover, an underlay and two cartridges. The Generic model A-1 names a cover in the title, then disagrees with itself on size. The Tekapo bullets do not list a cover, a filter or a ground sheet. The SENODON and the drop-stitch Generic use a cover only inside an energy sentence. BISHTA’s buyers’ guide treats an inflatable as vinyl, a pump and a sanitation routine. The Aruba names a Type VI cartridge. The EASE.ZONE names two. The others say filter without a count you can reorder, or they say nothing.

Supply you can point at

None of these six raw files names a BS 1363 plug. The Tekapo voltage field says 230 V AC, which is the UK mains figure, while the power-source field says DC/CA and the plug is still absent. The EASE.ZONE bullets say 220–240 V and the voltage field says 220 volts, again with no plug. The Aruba’s power-source field says Battery Powered. The bullets do not mention a battery, so do not repeat battery-powered as a fact about the heater. The SENODON is corded electric with no voltage. Both Generic listings leave supply blank. Stop the purchase when the seat line contradicts itself, the cover is only a percentage, or the supply field fights the bullets.

Common questions

How many people fit if the title says six?
Six is the Tekapo’s title and its seating field, not a measured UK test. A France review in the file says the width suited four adults. The EASE.ZONE title also reaches six, while its seating field says 4 and an Italian review would stop at three adults. Treat six as the maximum the advertiser printed.
Why do two seat numbers appear on one page?
They appear because the title, a bullet and the seating field were not written as one specification. The Generic model A-1 says 4–6 in the title and 2–3 or 4–6 in a bullet. The SENODON says 2–4, 2–3 and a seating capacity of 3. When two numbers disagree, you do not have a capacity. You have a listing that has not settled.
Is a cover in the box?
It is listed for the Aruba, for the EASE.ZONE, and in the title of the Generic model A-1. It is not listed for the Tekapo. On the SENODON and the drop-stitch Generic, a cover is assumed by an energy-saving sentence and is not clearly included. If the word cover is missing from the included list, budget for one before you compare running costs.
Does any listing state a UK plug?
No. None of the six raw files names BS 1363. The Tekapo states 230 V AC and the EASE.ZONE states 220–240 V, both without a plug type. The Aruba field says Battery Powered, which the bullets do not explain. The SENODON says corded electric. The two Generic listings do not state a supply.
What should the patio support before I order?
It has to support the water, the tub and the people, on a flat base. The only clear litre figure in this set is the EASE.ZONE’s 910 litres, about 910 kg of water, plus a 29 kg tub. A deck or balcony needs a structural check. Stones or a slope are reasons to move the site.
Which conflicts should stop me buying?
Stop if the seat count, the jet count or the size appears twice and the two figures disagree, as on the SENODON’s 72 inch title against a 66 × 58 × 38 cm field. Stop if the cover is only inside a percentage. Stop if you needed a plug type and the listing does not have one.
