File photo shows couples enjoying outdoor bathing. A Dutch company has created a hot tub that can travel with people. Called the Weltevree Dutchtub, it is a portable, stand-alone basin powered by a wood-burning stove. The half-sphere weighs around 165 pounds (75 kg) and holds 171 gallons (647 liters) of water - enough for four people to enjoy it. [Photo/IC] |
