Tired of making your daily trek to the shower across ice-cold tile? Create a comfortable environment by warming the floor. There are two systems on the market. Radiant floor heating uses a thin electric floor mat installed in thinset cement under the tile. The system is controlled by a thermostat and is the best option for heating a small section. The second option, hydronic heating, uses hot water circulating through plastic tubing. It's good for larger areas.
