Sustainable bathrooms incorporate green materials, efficient fixtures, and elements of sustainable design. Changing out fixtures manufactured before the water conservation mandates of 1994 will immediately ease the bathroom's impact on the environment as well as household finances. Low-flow shower heads, faucets, and toilets are the cornerstones of green bathroom design.

An energy efficient and water-wise bathroom can save significantly on monthly utility bills. Using low-flow water fixtures can save thousands of gallons of water per year.
