How are hydrotherapy pools made?

Our completely custom-built stainless steel hydrotherapy pools have many benefits. You can read why in this blog, but two of the things we like to emphasise is how long-lasting and cost-effective they are.

This is due to the way that our hydrotherapy pools are constructed. Our unique methods and techniques keep our pools from springing leaks and requiring maintenance every few months.

So how exactly are our hydrotherapy pools made?

What we think about first

Before we even get to the manufacturing stage, one of our hydrotherapy pool specialists will have a consultation with the client to work out exactly what and who the hydrotherapy pool is for. We’ll think about where the pool will be installed, and whether it will be for just one user or multiple users (e.g. a school or rehabilitation centre) at once.

We’ll then discuss the optional features available as well. We can install colour-changing lights, water jets, whirlpools, canyons and various other things to ensure that your hydrotherapy pool meets your needs perfectly.

Building the Pool

As our pools are made from stainless steel, they’re much quicker and easier to build than a typical tiled one. We use sheets of stainless steel, measuring them to the precise dimensions of your pool, and then fused together with mechanical anchorages and cold welding.

The exterior of the structure is coated in a fibreglass layer that is attached to a steel tubular structure, adding an extra layer of structural support.

Our cold welding technique prevents the development of micro-perforations, therefore reducing the chance of leaks forming in the structure of the pool. Cold welding also means that the steel will not expand or contract, so the surfaces will remain perfectly flat.

Installing the Pool

Before the pool is craned in, the main site contractor will dig up the ground where the pool is going to go. Concrete foundations will be laid at the base and up the sides of the ground, giving the pool a stable surface to sit on.

Whereas a tiled pool would be installed once the structure of the building has been almost completed, our stainless steel pools are craned in much earlier on in the building process. The pool will be lifted in one piece and guided into the space that has been made for it.

When it is in position, the pool is covered and left until everything else on site is completed. Only then will we finish installing the pool.

Final Stages

Once the project is almost complete, the pipes and plumbing will be connected to the pool. We will also install any extra features (jets, lights, etc) at this point.

The plant room will be setup with everything in place to ensure that the pool is kept at the right water level, and one of our hydrotherapy pool specialists will come and check all the work before handing over the project.


Although our hydrotherapy pools may look more stylish and expensive, they’re actually much cheaper when it comes to manufacturing, servicing, and maintenance. They’re better for maintaining high levels of infection control as well, and we can make them completely customised to your needs.

Our patented welding and construction methods make our hydrotherapy pools completely unique, reliable, and long-lasting.
