What is the best kind of material for a toilet?

The best materials for a toilet typically include vitreous china and porcelain, as these materials are durable, non-porous, and easy to clean. They resist staining and odors, providing a hygienic surface. Additionally, some modern toilets may incorporate materials like ceramic or high-quality plastics for specific components, but vitreous china remains the industry standard for its balance of functionality and aesthetics.
