Cold Plunge Pools, Engineered for Clean, Consistent Cold
A cold plunge only works if the water is reliably cold and genuinely clean. Aqua Spazio designs and installs built-in and freestanding cold plunge pools that hold a set temperature, typically between 3°C and 12°C, with filtration and water treatment designed for how often they're used.
Our cold therapy installations
-
Built-in plunge pools: tiled, stone or stainless steel, set into the floor or raised, indoors or outdoors.
-
Freestanding plunge tubs: for gardens, gyms and spaces where building in isn't practical.
-
Twin plunges: two pools at different temperatures, so beginners and regulars can both use the space.
-
Ice fountains and drench buckets: a quick, intense cold hit after the sauna or steam room.
-
Experience showers: cold mist, rain and bucket showers as part of a hot–cold circuit.
Why the engineering matters
People step into a plunge straight from the sauna, so the water sees a high bather load for its small volume. That means it needs more than a chiller. We design every plunge with:
-
A correctly sized chiller to hold temperature, even with repeated use
-
Filtration with a short turnover, sized for real usage
-
UV and residual disinfection, following PWTAG guidance for commercial installations
-
Insulated construction and covers to reduce running costs
-
Safe access: steps, handrails and slip-resistant surrounds
Home and commercial plunges
At home, a plunge can sit beside a sauna, in a pool hall or in the garden. For gyms, hotels and wellness centres, we design commercial-grade plunges with the water treatment, testing regime and safety features that daily public use demands.
Frequently asked questions
How cold should a plunge pool be?
Most people use 3–12°C. Twin plunges at, say, 4°C and 10°C let users choose. We set the chiller to suit how the space will be used.
How is the water kept clean?
Through continuous filtration, UV and a residual disinfectant, with the system sized for bather load rather than just volume.
Can a cold plunge go outside?
Yes. Outdoor plunges need insulation, a cover, a weatherproof chiller location and a power supply.
What does it cost to run?
Running cost depends on insulation, cover use, chiller efficiency and how warm the surroundings are. We design to keep it low.
