Go low-flow yet luxe

One of the simplest, low-cost-but-high-impact upgrades you can do is replace your showerhead. The options for eco-conscious water-saving models are better-looking than ever—like this oversize, rain-can style, which features clean lines and a wide, satisfyingly powerful spray. Best yet, it can be screwed on in just seconds (no tools required!) and rings in at less than $30. Opella by DeNovo Rain 6-in. Chrome Showerhead, $27; overstock.com
