The haliburton spa hot tub is the best portable spa on the market. It comes direct from the Canadian Spa Company. It assembles in less than 20 minutes and plugs into a normal 13 amp socket. It looks like a much dearer permanent spa. It comes with a lockable cover, solid state digital controls, aromatherapy dispenser and 130 heated air and water jet.
It beats the inflatable stuff all hands down-just look at the negative reviews on the inflatable spas. I have a haliburton in my back garden and wouldn't have anything else.
