The concepts of green living and health and well-being often go hand in hand. Ernesto Santalla designed a modern bath retreat that embodied these ideals in last year?s CharityWorks GreenHouse?a sustainably built showhouse in McLean, Virginia, that was sold to a family who toured it. All of the materials, furnishings?and even the art?Santalla selected are sustainable. A centerpiece of the space is the shower wrapped in cedar with a wall of river-rock stones and a cascading waterfall (using re-circulated water) that introduces sounds of nature into the mix. Artwork includes a large abstract piece by Dan Steinhilber made with recycled plastic bags (over the day bed) and a delicate hanging sculpture made by Barbara Josephs Liotta from remnants of black granite hanging near the cedar shower enclosure.Santalla?s creation illustrates how a spa can fit into any space in a home. ?A bathroom doesn?t have to be fully enclosed,? he says. ?You can expand the notion of a spa to include a living area with a relaxation space.?
