Lay-Z-Spa (Bestway)Lay-Z-Spa Santorini HydroJet Pro

The Santorini is the entry point into Lay-Z-Spa's HydroJet Pro line, and it is what you buy when air bubbles aren't enough. Its 10 pump-driven HydroJet Pro jets deliver targeted back-and-leg water massage that no cheaper AirJet-only tub here can match, backed by 180 AirJets for all-over warmth. It seats seven, adds WiFi app control so you can pre-heat and schedule remotely - genuinely useful for shaving running cost, which the budget picks can't do - and uses ColorJet LED plus EnergySense-class insulation; Lay-Z-Spa measured 58.8% less power over 73.4 hours versus its older, non-EnergySense models. The catch is price and bulk: at around a thousand pounds it costs roughly twice the Paris, and it is big and heavy to fill. It ranks just below the Paris because that value gap is hard to justify unless you specifically want the water-jet experience and year-round use; if you do, it's the most capable tub on this list.
