Cost of Running a Hot Tub

Cost of Running a Hot Tub

To figure out the cost of running a hot tub, you need to take into account the cost of the tub itself, product modifications, installation, maintenance, and utility costs. Consider an approximate list of expenses from the infinity edge hot tub. Prices are approximate and valid at the time of writing.

Hot tub and modifications

Currently, the basic cost of a tub ranges from $15,000 to $35,000.

Some people need modifications: spa top cover ($2,100), spa pneumatic elevator ($4,000), auxiliary water chiller-heater ($2,500), aromatherapy package ($400), or outer shower (from $3,000).

Installation and maintenance

The cost of installation is calculated by your plumber. Manufacturing companies offer an installation supervision service that costs from $1,500. At least once a year, it is worth passing a technical inspection (from $100).

Maintenance of hygiene

For the water to remain clean and have the optimal chemical composition, you need to use a hardness stabilizer, disinfectants, filter cleaners, and tub cleaning products when draining water. You will also need test strips to determine the chemical parameters of the water. The basic set of products costs around 150 dollars.

Water and electricity

Expenses depend on the tariffs in your region. This formula helps to determine the required frequency of a complete water change: Volume of water in liters ÷ average number of people bathing per day ÷ 12 = Number of days until the next water change.

If your bathtub holds 300 gallons (1,135 L) and two people bathe in it per day, then: 1,135 L ÷ 2 ÷ 12 = 47.2 days before a water change.

To calculate the power consumption, the power of the pump and heater should be taken into account. For example, if the power of the heater and pump is approximately 5 kW, then heating the bath for an hour costs a 5 * cost of 1 kW * h in your region. After full heating, the tub maintains the set temperature, so the consumption is lower.
