A pedestal sink is a sink that is supported by a pedestal, or a small column. The pedestal can be made of different materials, such as wood, metal, or stone. The sink is usually made of porcelain, but it can also be made of other materials, such as glass or metal. The pedestal sink is a popular choice for small bathrooms because it takes up less space than a traditional sink. The pedestal sink is also a good choice if you want to create a more elegant look in your bathroom.
