The London SE is the spa you'd pick if you've decided a six-person hot tub is the right answer, and you'd rather not spend Niagara-flagship money to get there. Square footprint, full-length lounger on one side, five seats arranged around the remaining three. Same Balboa controls, same Lucite® acrylic shell, same Mountain Pure™ UV + ozone sanitation and same year-round winter-rated build as the top of our range — at a price that lands several thousand pounds below the Niagara flagship.
Forty-four adjustable stainless steel jets split across the seats — neck, shoulder, lumbar and calf clusters for each position — driven by a dual-pump hydraulic system with diverter control, so you can direct full pressure where it's needed rather than splitting it evenly across every seat. Air venturi valves at the rim let each person dial their own air injection without affecting the others. An Aurora™ Premium LED package (perimeter lighting, underwater lights, LED-backlit cascading waterfall) gives the spa real character after dark. Blackout Insulation, ThermalSprings™ heat reclamation, a 5″→3″ hardtop tapered cover with locking straps — winter-rated and built to be used all year.
At this size you'll need a dedicated 32 A spa circuit fitted by an electrician (a half-day job, typically £300–£700) and a level base that covers the full footprint. Get those two things right before delivery and the London SE is a decade-plus spa that you'll use several times a week — not a garden ornament that becomes a summer-only thing once the energy bill hits.
