Epoxy grout is totally maintenance free. Unglazed tile, marble or granite require the whole floor to be sealed with special sealers designed specifically for them. Ceramic tile can be cold if there is cold air beneath it. If your home has a heated basement, your ceramic floor will be the warmest floor in your home because the warm air from your basement will be retained by your tile floor. If your have a crawl space under your home there is a solution.
Heat mats are now available that can be installed under tile that heat the floor.
You can even put a thermostat on the mat so that you can keep it at whatever temperature suits you. All rights reserved.
