A hot tub, or a sauna tub, is a pleasant and relaxing amusement for people of any age during any time of the year. You can use the hot tub all year around but it creates an especially pleasant mood on cold winter days.
Wooden hot tubs are traditionally round in shape. The diameter of different tubs varies between 160 and 200 centimetres and they have been designed for 4–10 people. You can place the hot tub almost anywhere as long as the surface is flat. The water in the hot tub is heated up to 35–38 ˚C.
