Abstract
Abstract A toilet comprising a base structure which is divided into separate upper and lower sections. The lower section is mounted on a support, while the upper section is releasably secured to the lower section from outside the lower section which allows access to the internal parts of the toilet without removing the base from the support or disconnecting the inlet water line. The front and side walls of the base are devoid of any openings, except for the control lever, so that water cannot splash into the interior of the toilet base.
