Lay-Z-Spa (Bestway)Lay-Z-Spa Paris AirJet

The Paris is the tub we would point most buyers to first because it covers the things that actually bite over time without pushing into four figures. It seats six, uses Lay-Z-Spa's Freeze Shield so it can run October to March rather than being a summer-only toy, and adds an insulated lid, an energy-saving timer and a 7-colour LED light system, where the cheaper CleverSpa Onyx has only a single-colour underwater light. Lay-Z-Spa also states its tubs are the most energy-efficient inflatable brand on the UK market - heating around 17% faster and cooling roughly 25% slower than competitors on average - which matters more to the weekly bill than the sticker price. The trade-off against the step-up Santorini is massage: the Paris runs 140 AirJets (gentle air bubbles) rather than pump-driven water jets, and it has no WiFi app. Against the cheaper Onyx, you pay more but gain better insulation, LED lighting and six seats. Across the range, Bestway's Lay-Z-Spa is among the most widely sold inflatable brands in the UK, which tends to mean readily available spares, liners and pumps - reassuring for a product that lives outdoors.
