Hot Tub Installation & Setup

Guides, ownership advice and updates from the Redhill showroom — written for UK buyers deciding between hot tubs, swim spas, saunas and the kit that keeps them running.

Where you put a hot tub matters as much as which one you buy. An acrylic spa happily sits on an existing patio or a 3–4″ concrete pad — no laser-levelling, no reinforcing, just roughly level (the shell tolerates around 2″ of variation over its length). An inflatable on the same base needs to be flatter, because water weight pushes outward against the vinyl side wall and an uneven base concentrates pressure on one side. A swim spa is different again — 6″ of concrete covering the full footprint is the minimum.

A plug-and-play 13A model arrives ready to fill; a hardwired model needs an electrician on site before delivery. Below: how to choose between deck and patio, what plug-and-play actually saves you, what to expect on delivery day, and why warranty registration matters.
