Tile dealers may only sell tiles. Contractors generally install them. In some cases, the two may be the same company.
Professional tile installers may specialize, or may work on other remodeling and home improvement tactics. Companies may sell only standard ceramic, only porcelain, or all kinds of tiles. They may also sell slate or marble.
Murals are a particularly specialized area. Mural artists use small tiles to create a picture and may be hired by wealthy home owners or by companies. Even local governments may install a mural to brighten up an underpass or highlight a park. Most murals are ceramic or porcelain, with the colors created by glaze.
Most dealers or contractors sell both natural and glazed tiles. Interior designers often hire contractors to lay specific patterns of decorative tiles. In general, kitchens and bathrooms, including showers, require the same techniques. Pool tiling is, however, often a specialist operation. Pools need to be watertight and special glazes are often used. Most outdoor tiles are marble or porcelain.
Mexican and Italian tiles are generally used for decorative purposes. Some dealers specialize in one or both of these high quality products.
Contractors generally lay both walls and floors, but some may specialize in one or the other. Cheap plastic tiles and fake tiles such as patterned vinyl may also be sold by some dealers and contractors. Installation can be performed by the home owner, but is often best left to a professional as it is easy to get tiles crooked.
New tile walls and floors are constantly required by both new buildings and existing ones. Dealers and contractors tend to be affected, however, by economic cycles in the construction industry and home prices. New constructions may go down, however, at the same time that demand increases for remodeling and home improvement.
