Abstract

A lightweight toilet unit is provided particularly for use with vehicles such as boats, RVs, and trailers. The toilet unit includes a plastic toilet bowl having an interior surface, open top, and exterior surface, a plastic body positioned exteriorly of the toilet bowl exterior surface, and a plastic toilet seat for partially closing the open top of the toilet bowl. To enhance the longevity and effectiveness of the toilet bowl without significantly increasing the cost and weight of the toilet unit, a layer, coating, or thin walled insert liner made of a non-polymeric substantially poreless material that is not degraded by contact with excrement, light, or toilet bowl cleaning agents, is disposed interiorly of the plastic toilet bowl and is at least partially supported by the plastic toilet bowl and may comprise porcelain, glazed ceramic, glass, corrosion resistant sheet metal, or sheet metal with a corrosion resistant poreless interior coating. The toilet bowl may be rotatably supported by a socket which mounts a common valve actuator (e.g. pedal) for supplying flushing liquid to the interior of the insert liner and substantially simultaneously opening a spherical segment valve at the outlet at the bottom of the toilet bowl.
