The towering shape of the Sunnydaze Decor Tower Indoor/Outdoor Floor Water Fountain really comes to life when a steady stream of water begins flowing across the multi-colored slate. This contemporary design is self-contained, with a recirculating, submerged pump that doesn't require any additional plumbing. The pump sends water flowing down the resin-covered slate and into a bed of loose river stones. A single bulb adds a touch of light that provides a bit of drama after the sun goes down. All you need to get started is a bit of space and an electrical outlet.
