With years of experience in the R&D and manufacturing of outdoor spa equipment, LOVIA® provides global partners with one-stop OEM/ODM services, including Outdoor Spa Hot Tub and Outdoor Swim Spa, helping businesses create product portfolios tailored to their market positioning for different business scenarios.

The most reliable method is not to observe whether the water is clear, nor to guess based on the amount of foam, but rather to test the calcium hardness and make a comprehensive judgment based on pH, total alkalinity, water temperature, and the target range recommended by the equipment manufacturer.

Currently, the most convenient home testing method is to use an electronic TDS meter. TDS meters typically measure the conductivity or related electrical properties of water and then estimate the total dissolved solids concentration based on the instrument's internal conversion factor.

Most outdoor spa hot tubs currently employ a "circulating filtration + water quality management" system. The system uses a pump to draw water from inside the tub into the filtration system, where it is filtered and then returned to the tub, maintaining a relatively clean water level.

After determining that calcium chloride needs to be added, it is recommended to first turn off the outdoor hot tub's heating function and turn on the circulation pump to ensure sufficient water flow. Then, weigh the calcium chloride or calcium hardness enhancer according to the product label instructions.

Single-zone swim spas typically feature a unified water temperature and an integrated layout, emphasizing compactness, efficiency, and space optimization. Dual-zone swim spas, conversely, utilize a partitioned design that separates the swimming area from the hydrotherapy zone, allowing for simultaneous exercise and relaxation.

As a player in China's spa equipment industry, LOVIA® has long focused on the R&D, manufacturing, and sales of products such as outdoor hot tubs, swim spas, and cold plunge tubs, dedicated to providing comprehensive OEM/ODM solutions to global clients.

Take LOVIA® as an example: our company has long specialized in the outdoor hydrotherapy equipment sector, boasting professional production facilities and a comprehensive manufacturing system dedicated to the R&D and production of outdoor hot tubs, swim spas, and related SPA products.

A truly premium outdoor hot tub experience requires a holistic approach, encompassing hydrotherapy systems, water quality management, ergonomic comfort, atmospheric design, and long-term maintenance.

From outdoor hot tubs and massage spas to swim spas that combine swimming training with rehabilitation functions, outdoor spa equipment is increasingly being integrated into hotel master plans. These facilities not only transform the design of traditional leisure areas but also generate new revenue streams and enhance brand value.
