Most four-person hot tubs aren't plug-and-play — they're scaled-down versions of the six-seaters, which means a 32 A supply, a consumer-unit upgrade, Part P certification and an electrician on site. Most plug-and-play hot tubs aren't four-person — they're two-seat dipping tubs. The Calgary sits in the gap: four adults, 24 jets, 4 HP pump, standard 13 A socket. No electrician. No consumer-unit work. Plug it in, fill it from the hose, you're in the water on day one.
Twenty-four stainless steel jets driven by a single 4 HP pump, with air venturi valves that let you dial each jet's air injection up or down at the rim of the shell. At 700 L, the 50 ft² Glacier antimicrobial filter turns the whole tub over in minutes, not hours. Balboa digital controls, Lucite® acrylic shell, triple-layer insulation with infra-red reflection, ThermalSprings™ heat reclamation pumping pump waste heat back into the water, 5″→3″ hardtop locking winter-rated cover, Aurora™ Premium LED lighting, integrated aromatherapy canister and Bluetooth audio — the same engineering as the bigger tubs in our range, sized for a patio corner instead of a project build.
And because it runs off a standard 13 A socket, it's portable. Drain it, flip it on a dolly, it comes with you if you move house — a category of spa most people don't know exists. If you need family capacity without an electrician callout or a six-seater's footprint, the Calgary is the practical middle ground.
