Not every seven-person household fits a 228 × 228 square into their garden. Some have a narrower run down the side of the house, a long thin patio, or a lawn that takes length better than width. The Kingston SE is the spa we build for those gardens — a rectangular 240 × 216 cm seven-person hot tub with seating laid out around all four walls rather than a lounger along one side, and a footprint that fits the shape of a typical British back garden.
The spec is flagship-adjacent without being flagship-priced: 55 adjustable stainless-steel hydrotherapy jets on our WhiteWater™ Jet Delivery System, fed by two independent 5 HP pumps, four air-venturi valves for per-person pressure control, and the same Balboa 3 kW heater with Aqua AI smart sensors that shut the element off within half a degree of your target. Four LED-backlit cascading waterfalls, Aurora™ Premium LED lighting, Bluetooth audio and an integrated aromatherapy canister — same year-round build quality as the Niagara flagship, without the Niagara's air blower, Captain's chair or diverter valves.
Water care is where the Kingston quietly steps ahead of every tub below it in the range: 2 × 50 ft² Microban Glacier filters (100 ft² total — double the filter area of the London SE and Erie SE) paired with the Mountain Pure™ UV-C lamp + built-in ozone generator. Sized for seven adults soaking regularly, not a guest tub that gets used once a week. ThermalSprings™ heat reclamation captures pump waste heat into the water, Blackout Insulation triple-layers the shell, cabinet and base, and a 5″→3″ tapered winter-rated hardtop cover keeps the heat in when you're not in it. Built for British seasons, British gardens, British families.
