It’s light enough that two people can move it around, you can put it on top of your car and take it camping with you. It fills up with a garden hose, and warms up with the use of a nifty coil off the side, where you burn wood, and water runs through pipes.
In my mind, every yard needs one, large or small. Why not? The manufacturers of Dutchtub suggest using the leftover gray water (that means dirty water with no chemicals) for your garden, an excellent green idea, rather than trying to maintain the mini chem lab many hot tubs require.
