In bathroom remodels in San Francisco, California, tile installations are common. This is mainly because of tile’s hygienic and waterproof qualities. They can be used on floors or walls, and they provide a durable, attractive surface. Tile is also common in bathrooms because it’s hygienic and easy to clean. Some people, however, have reservations about calling a San Francisco tile contractor for their bathroom. “Won’t the floors be cold?” they ask. While somewhat true, the temperature of a tile floor depends largely on the surface beneath it. If the tile is installed over a wood subfloor it will be warmer than if installed over concrete. If you’re concerned, ask a local contractor about undertile heating.
