Outdoor bathing culture is really gaining popularity though unless you live in the Southern Hemisphere or some where tropical, its not really recommended right now in winters. The Hikki Bathtub cashes on to this trend and is a stand-alone bathtub that catches the eye instantly thanks to its grandeur and visually imposing design. This almost quixotical tub contravenes most design conventions and is quite a respite from the usual desiccated bath tubs. An alternative to hot tubs, this wood-fired bathtub has been constructed of resistant aluminum and it also comes with a heat-treated birch.
