If your spa hot tub has the following characteristics, it is not recommended to use it as a shower: • The bathtub is made of thin acrylic walls, which are not suitable for standing; • It lacks an anti-slip bottom or safety handles; • Electrical components are exposed or close to the shower head area;

The water temperature in a regular bathtub gradually decreases, while a spa hot tub is equipped with a constant temperature heater, maintaining a constant temperature. This means the body's sweating response lasts longer, resulting in greater water loss.

Under normal circumstances, spa jacuzzi bathtub water should be clear, soft, odorless, and have a natural feel. If a "slippery" feeling occurs, it usually means that the chemical balance in the water has been disrupted or organic matter has accumulated.

It is generally recommended to maintain the water temperature between 36℃ and 40℃. Young, healthy individuals with normal circulatory systems can soak for 25-30 minutes; the elderly or those with weak cardiovascular systems are advised to limit it to 15-20 minutes.

In high-end spa jacuzzi bathtubs, the two are often used in combination to create a dual hydrotherapy experience: first, bubbles soothe the nerves, then water flow deeply relaxes the muscles, achieving balanced relaxation throughout the body.

Most spa hot tubs are equipped with electric heaters or heat pumps, using a temperature sensor to monitor the water temperature in real time. When the water temperature drops below the set value, the system automatically heats up; once the target temperature is reached, heating stops to maintain a stable temperature.
