The interior and lid of the hot tub are made from rotationally cast PE plastic (polyethylene plastic). The seating cast inside is insulated with 40 cm foam polystyrene.
PE plastic is very easy to keep clean. The hot tub is provided with a drainage hole and a drainage pipe with a tap. The hot tub and the lid are very weather resistant, not being affected by heat or cold. Thanks to the lid of the hot tub, the water of the hot tub heats up more quickly and no debris or dirt gets into the water of the hot tub when the lid is closed.
The external heater of the hot tub made from marine aluminum can be heated with max. 50 cm long wood. In this case, the heating time is approx. 3-3.5 hours. When heating with wood briquettes the heating time is approx. one hour less (2.5-3.5 hours). Briquette consumption is approx. 25kg. The time needed to heat the hot tub also depends on the time of year, so in winter the heating time can be significantly longer than in summer when the hot tub heats up faster.
