Hot Tubs, also known as spas, whirlpool baths, and roman baths, are engineered tubs or pools of hot water used for relaxation. Located either indoors in specialized rooms or outdoors in backyards, roofs or terraces, hot tubs are sized to seat multiple people simultaneously with various seating configurations and angles with integrated jet streams.
The water in a hot tub is not changed with each used, but sanitation methods similar to those used for swimming pool filtration are used. Calderas, where hot stones were placed to heat the water, were the earliest form of hot tubs. Today, hot tubs are typically heated by an electric or natural gas heater, though they continue to be found at natural hot springs.
Hot tubs, resembling large wooden barrels, initially found use in regions with natural hot springs, where people enjoyed therapeutic soaking. Over time, these communal soaking spots evolved into private wooden tubs, often heated with stones or wood-fired stoves. In the mid-20th century, advances in technology and materials transformed these wooden vessels into the modern acrylic, jet-equipped versions. Pumps, heaters, and filtration systems enhanced the experience, making relaxation and hydrotherapy accessible to many, not just those near natural springs.
Hot tubs are moving towards smart, eco-friendly designs. Modern models often integrate with home automation systems, allowing remote temperature control and maintenance monitoring. Energy-efficient heaters and recyclable materials cater to environmental concerns. Multi-sensory experiences with mood lighting, sound systems, and adjustable jets heighten relaxation.
However, challenges include water conservation, ensuring durability in varied climates, and reducing operational costs. As wellness becomes paramount, hot tubs will continue evolving, marrying luxury with sustainability and technological innovation.
The preferred temperature of a hot tub by users ranges between 100°F-102°F (37.7-38.8°C) with 100°F considered the safest temperature for adults (extra precaution should be taken with children). The maximum temperature for a hot tub is 104°F (40°C).
The weight of a hot tub is dependent on the size. A small one that holds two to three people and is filled with water can weigh up to 3,000 lbs (1360 kg). A larger, six person hot tub can weigh up to 6,000 lbs (2721 kg). Empty, these hot tubs weigh 500 and 1,000 lbs (227 and 453 kg) respectively.
To move a hot tub, prepare by gathering straps, dollies, and other needed supplies while also renting a moving truck sizeable enough to fit the hot tub. It’s important to note that this is a task that cannot be completed alone, requiring the aid of up to six people. First, disconnect the plug from the outlet and remove all cords. Next, drain the hot tub. This step is easier said than done and typically requires a pump. The water should be drained into a street gutter rather than straight into the yard as damage may occur. After, slide the dollies underneath the hot tub. It is recommended to place pieces of plywood underneath the tub first to create a flat surface and making the transition onto the dollies easier. Secure the hot tub on top of the dollies via straps. The final step is to move the tub onto the ramp and push it into the truck.
