Soap bars are slippery when wet and tend to glide when kept on a flat surface. In order to hold them on a place and keep them dry, you need a soap dish. Decorative soap dishes offer a place to present your favorite bar soap in an aesthetically pleasing manner. They are traditionally oval in shape and can be brass, chrome or glass. Soap dishes can be installed on the side of the bathtub, washbasin or wall mounted.
