A toilet bowl that has the additional chamber (2) will allow to keep and wash the brush (3) in a water plug (4) that is frequently changed. This eliminates the need in a special vessel to keep the brush, which will seriously improve the sanitary environment in the toilet room. This is especially important for little children that will not any more be able to spill the contents of the vessel all around the place. The unpleasant procedure of washing the vessel will also go away.

Every time the water is flushed down the bowl (1), some of the water flow via the tap (6) of the canal (5) will change the water plug (4). The old sedimented water through the siphon (7), sewage Y-joint (8) and outlet collector (9) will be removed to the sewage. This will happen every time, regardless of whether or not the brush was used. This will remove the possibility of the water's stagnation in the plug (4) and appearing of a source of germs.

The bowl described here can be manufactured using the old regular equipment. The only complication is a slight modification of the die. The other processes, from obtaining raw material for ceramics to assembling the bowl will remain the same.
