Three Step Filtration On A Serenity Hot Tub

The ClearSpring Filtration System provides a three-stage process for a clean and healthy hot tub. First, the Ultra Flow Grill uses a catch barrier to prevent debris from re-entering the hot tub while allowing for maximum water flow. Next, the Skimmer Net acts as the first line of defense, trapping large debris before it can reach the filter cartridge. Finally, the filtration system uses its microfiber material with dense inner core and large surface area to capture even the smallest particles across the two filters. This entire system, combined with our energy-efficient hot tub pump, ensures optimal water quality with a simple and easy-to-maintain process.

Style & Substance Without Costly Bells And Whistles

What Sets Serenity Apart?

While our Signature Self-Cleaning Collection is renowned for its revolutionary self-cleaning technology, we also offer models that provide the same exceptional core experience at a more accessible price. Our Serenity models, without the automated cleaning system, are built with the exact same high-quality components you'd find in our top-tier tubs. This includes the identical powerful pumps, efficient plumbing, and superior insulation that ensure a perfect hydrotherapy experience and long-term durability. By forgoing the self-cleaning feature, you can still enjoy the deep, relaxing soak of a Serenity Hot Tub, confident in the knowledge that its internal engineering and build quality are second to none.

Serenity Hot Tubs Are Built To Last From The Ground Up

Serenity hot tubs by Hydropool are designed for durability and energy efficiency, using a fully sealed system to manage heat in any climate. The Everlast Frame and a Polymer Insulated Floor support the strong Edgewater Shell, creating a weatherproof system that keeps heat in during the winter and releases it in the summer through adjustable venting.

This Weatherseal Insulation System uses multiple layers to save energy. Hydrowise Thermal Blankets, inspired by NASA technology, reflect waste heat from the pumps and plumbing back into the tub. This reduces how often the heater needs to run, which in turn lowers your energy bill. The Weatherseal Cabinet panels also reflect heat inward while being easily removable for maintenance.

To further improve efficiency, the hot tub features EcoHeat Exchange Technology, which uses fully adjustable vents to regulate the temperature and minimize the use of the heater. The entire system works together, using a hybrid approach that captures and reuses radiant heat. Additionally, the heavy-duty cover provides a final layer of insulation and safety, making Serenity hot tubs among the most energy-efficient in the world. On average they use 17% less energy than other leading brands.
