Full steam ahead! The 'Hot Tub' boat which can let you lazily cruise down the river in comfort<br />
<br />
There's almost nothing more luxuriously relaxing than taking a dip in a hot tub, except perhaps taking a slow cruise down a beautiful river.<br />
Now you can combine the best of both world - with a hot tub cruise thanks to an ambitious company in the Netherlands, which created the hybrid machine to provide the ultimate river journey.<br />
The 'Hot Tub', powered by a steam wood-burning stove to heat the water and a propeller engine to keep you sailing merrily down the stream.<br />
The boat contains up to 2,000litres of water and comes with either an integrated electric motor or an outboard model.<br />
If you cannot wait and are already getting the cheque-book out, be warned you may need a little more patience, as it will take three hours to get the water up to the required heat.<br />
<br />
The creators say the water can be 'as warm as you want, but average people find a comfortable temperature of 38C and that is no problem for the HotTug heater.'<br />
Available to rent or buy, the hot tub boat is made from wood and fitted with glass-fiber reinforced polyester, measuring 240cm by 380cm by 110 cm.<br />
<br />
When used as a regular boat, eight people can enjoy a sail. Add hot water to the mix, and six people can still enjoy a mobile bath.<br />
If you are just after the boat, without motors or a stove, you are looking at around £7,200. Throw in the stove and other equipment and the price is around £13,000.<br />
But if you happen to be the owner of a private lake, this might be affordable enough to give you a very unique hot tub experience.<br />
