Perfect for small bath spaces: hotel-style towel shelves that double as towel warmers.
Above: Myson's Lekoro Classic Electric Towel Warmer in polished chrome is only 18 inches wide; $1,150 at eFaucets.
Above: The Lekoro features a back-lit on/off switch and comes with a five-year warranty. The rack needs to be hard-wired (the installation is not difficult, but requires an electrician).
Above: For a solution that does not require tapping into your wiring, the Luena Wall Mount Plug-In Towel Warmer Shelf, just over 22 inches, has a hollow steel frame that is filled with glycol; the liquid circulates through the rails when heated. It's $305.17 for the chrome finish at Signature Hardware.
