Nothing says ‘relaxation’ like a good, long soak in a bathtub. Those looking for a little sustainable serenity may enjoy the Air Bubble Massage Bathtub from Xianning Yanshan Bamboo Industry, Co. Ltd. Equipped with a pillow, faucet, hand shower, jets, massage device, and chair, the luxurious tub is made completely out of water-tight bamboo. Sustainable and possessing a low-carbon footprint, the hearty grass makes a warm, attractive alternative to porcelain or tile. The surface is treated with a nanometer level oxide compound material that deodorizes, sterilizes, and releases anions into the air. Adhering to the standards of the Ergonomics Association, the tubs also come in barrel and portable models.
