Most decks are designed to handle general outdoor furniture and activities, with a load capacity of 300 to 600 kg per square meter. However, a swim spa tub is a heavy item that can carry loads far beyond the typical deck standard.

Generally speaking, a high-quality swim spa tub can last up to 10 to 20 years under normal use and good maintenance. Higher-end brands and models can even exceed the 20-year service life, especially if regular maintenance and necessary parts replacement are performed.

The main role of baking soda in outdoor jacuzzi bathtubs is to increase alkalinity because it can provide bicarbonate, a compound that can increase the buffering capacity of outdoor jacuzzi bathtub water. Therefore, baking soda is usually recommended to increase the alkalinity in water rather than reduce it.

pH reducers are chemical preparations specially designed to lower the pH value of outdoor whirlpool hot tub water. The main ingredients are sodium bisulfate or hydrochloric acid. These chemicals can effectively reduce the alkaline components in the water and adjust the pH value to the ideal range.

The core technology of the whirlpool tub is the water flow system driven by a water pump. The water in the bathtub circulates through the water pump and sprays out from specific nozzles. Unlike the hydromassage of a whirlpool tub, a jacuzzi tub uses a mixture of water and air.

Risks of using a whirlpool hot tub for the elderly: 1. Increased risk of heart disease 2. Excessive acceleration of blood circulation 3. Risk of fainting and falling 4. Joint and muscle problems
