For those who have everything: Dutchtub

Can’t decide where to install your hot tub? You don’t have to with the Dutchtub, a portable whirlpool bath. Weighing only 165 pounds when empty, the colorful, mortar-like tub warms water through stainless-steel outer pipes that coil around a fire basket, letting a natural fire do all the work. Keep it in the backyard, or attach the eco-friendly tub to the top of your car and lug it up to a cabin in the woods for a weekend. It also features a wine-bottle holder with space for ice to keep your bubbly cool while you stay nice and warm.
