What a Small Garden Swim Spa Really Needs
A small garden swim spa is a compact, self-contained pool and hot tub in one unit, usually between 3.8 m and 4.2 m long, that needs a firm level base, a dedicated power supply and a viable delivery route.
The footprint is only part of the puzzle. Three things decide whether a compact plot works:
- A base that can carry the filled weight, which runs into several tonnes
- A power supply installed by a qualified electrician
- A clear route from the road to the final position
Swim Spa Installation Requirements You Cannot Skip
The base. A filled swim spa is heavy. The Pluto, our most compact model, weighs around 5,985 kg when full.
The power. Every model in our range needs a 32A RCD-protected supply. An electrician is required.
The access.
Getting the Swim Spa Base and Foundation Right
- Concrete slabs are the simplest reliable option for most gardens
- Decking must be built specifically to carry the load, not adapted afterwards
- The base needs to sit where water can drain away freely
- Leave clearance around the unit for the cover and for servicing
