The pipes and pumps in a spa hot tub are critical to its proper operation. When a spa hot tub remains empty for extended periods, residual water can accumulate inside the pipes and cause rust or corrosion. Even trace amounts of water can accumulate dirt over time, leading to blockages.

According to the Centers for Disease Control and Prevention (CDC) and the Consumer Product Safety Commission (CPSC), whirlpool hot tub water temperatures should never exceed 104°F (40°C). This is because at this temperature, the human body maintains normal thermoregulation and avoids hyperthermia.

A gazebo should be between 2.4 and 3 meters high to effectively shade the outdoor spa hot tub while ensuring air circulation and comfort.

One of the most important features of a whirlpool spa hot tub is its built-in water jet system. By adjusting the intensity and direction of the water jet, you can target specific areas of your back for a deep massage. The powerful water jets simulate the movements of a masseur, loosening tight muscles and stimulating the deep tissues of the back.

Chlorination disinfection is one of the most common and effective sterilization methods. Chlorine can effectively kill Legionella in whirlpool spa hot tub water, provided that the chlorine concentration is sufficient and the contact time is long enough.

Whirlpool spa hot tubs, with their warm and humid environment, provide ideal conditions for the growth of Legionella bacteria. If a whirlpool tub's water treatment system or disinfection measures are inadequate, Legionella bacteria can rapidly multiply and spread in this environment.
