What Influences the Cost of a Hydrotherapy Pool?
1. Pool Size
-
The biggest factor affecting price is the size of the pool. Hydrotherapy pools typically range from 3m x 3m (the smallest standard size) to much larger custom builds.
-
Expect starting prices around £70,000 for a basic 3m x 3m pool, with costs rising to £200,000 or more for larger or more complex pools. These figures usually include essential elements like the plant room and environmental controls.
2. Depth
-
Most hydrotherapy pools are between 1.2m and 1.5m deep. The larger the surface area and volume, the higher the price.
3. Plant Room Location
-
Every hydrotherapy pool needs a plant room for essential systems. Placing it close to the pool reduces long-term servicing costs.

4. Environmental Controls
-
Hydrotherapy pools require robust air dehumidification due to their higher water temperatures. Larger rooms or spaces with more windows need bigger, pricier air handling systems.
5. Filtration Systems
-
Filtration type matters. Skimmer systems are more affordable but only suitable for private/domestic pools. Overflow filtration, required for public or multi-user pools, costs more.
6. Installation Method
-
Stainless steel pools are quicker and less labour-intensive to install, often being craned into place. Concrete and tiled pools take longer and can be more expensive to maintain over time, even though initial costs are similar when installation is considered.
7. Additional Features and Finishes
-
Features like spa jets, current generators, special access steps, covers, and lighting will increase the price.
-
Upgraded finishes, such as vinyl linings instead of standard stainless steel, also add to the overall cost.
