When asked about the depth of a spa jacuzzi tub, the most common answer in the industry is around 90cm. This depth is not arbitrary, nor is it solely based on aesthetics; rather, it's a comprehensive balance of structure, safety, and ergonomics.

The bathtub water temperature is maintained between 36°C and 40°C. While this temperature is comfortable for humans, it's ideal for bacteria that thrive in warm environments. Legionella and Pseudomonas aeruginosa multiply rapidly at this temperature, and without regular water changes or disinfection, bacterial numbers can increase rapidly.

Spa jacuzzi tubs typically operate between 36°C and 40°C, a temperature range that is very close to but slightly above human body temperature. This temperature range has the following positive effects on the body: · Vascular dilation · Muscle relaxation · Nerve relief · Metabolic activation

Because spa jacuzzi bathtubs have a closed body, a circulating heating system, and independent water and drainage systems, they don't rely on fixed plumbing like conventional bathtubs, offering greater flexibility. As long as the power supply, water supply, and space requirements are met, spa jacuzzi bathtubs can operate effectively indoors or outdoors.
