Duravit. The Blue Moon and Sundeck indoor/outdoor pool collections offer an elegant option, with the Blue Moon (shown) boasting a circular water pool surrounded by a sleek square body, and the Sundeck featuring a luxurious wood panel surround. The whirlpool units maintain a constant 100.4-degree F water temperature, allowing for use day and night; when not in use, the tubs can be set to power-save or standby mode. The pools do not need a permanent water source, and the firm says they can be filled with something as simple as a garden hose; in addition, they feature three spa settings—power, relax, and emotion—that can be operated separately or in tandem using only water, a mixture of water and air, or only air. The basins are automatically disinfected with a dual-technology system that includes a filter to eliminate large particles and an integrated ozone generator. The pools come standard with a protective cover, underwater lighting, and a floating remote control that can direct home entertainment units from up to 100 feet away. 770.931.3575. www.duravit.us.
