Traditional Hot Tubs are made of wood and are deep - allowing you to sit or float in complete relaxation. The heated water is soothing and therapeutic, and must be treated on a regular basis. Although maintenance is essential, with modern sanitisers it is very straightforward. Chemicals are available at any pool shop and Ozonators are a viable alternative to keep the water clean and pure in your tub.
Heating of the tub is achieved either by electrical power or gas. Properly covered, the weekly power requirements of an electrically powered tub are equivalent to a moderately priced bottle of wine a week. Gas heating units, while more expensive to install, cost significantly less to run in the long term.
