This Heated Bird Bath supplies ice-free water all winter long using 150 watts of thermostatically controlled power. The heating element is completely hidden beneath the surface of the bath where it automatically cycles the water temperature between 5-10 degrees Centigrade (40-50 degrees Fahrenheit). Fully tested in sub-zero conditions, this bath will not crack in the winter cold. This bath may rest on the included 29" metal stand or be mounted to wood deck railings. The textured surface and contoured rim ensure a solid grip when birds land and the gradual slope encourages birds to bathe. This light beige colored bird bath will surely add to any backyard, patio, or garden. Dimensions: 20" Dia., 4.25" D, 15" cord, 29" stand. 3-year manufacturer's warranty.
