We use an acrylic caulk containing mildewcide for protection up to five years or more. For your tile removal or renovation, high-end bathrooms use polished granite that is extremely stain and scratch resistant. However, porous types such as marble and limestone will stain and etch if toiletries and cleaners aren’t cleaned up immediately. Honed surfaces can show oil marks and water spots. Let us help your decide on your specific needs and tile to use.
