All indoor Jacuzzis are similar to large bathtubs with jets. Water must be filled each time it is used and the temperature.  We have installed automatic hot water heaters, so you can fill the Jacuzzi without worrying about the hot water heater’s capacity.
An outdoor hot tub is filled with water at all times. The water is treated with chemicals like a swimming pool and has a heater to consistently heat the water.  Our hot tubs are monitored by trained staff before each check-in and after each check-out.
