Abstract: A toilet device, in particular for bedridden persons, includes a lower shell (20) whose top side has a support surface (45; 80, 82) surrounding an opening (30) to receive the stool and urine of a person on the lower shell, in such a way that there is a first sealing line portion between the person and lower shell, which first sealing line portion extends from the inside of one buttock over the coccyx or lower back region to the inside of the other buttock. An upper shell (22) can be mounted to the lower shell and is so formed that in a transitional region between the lower shell and the upper shell (22) connected thereto there are second and third sealing line portions, adjoining the first sealing line portion, in the region of the uppermost insides of the thighs or the lowermost trunk region, which are adjoined by a fourth sealing line portion which extends from one side of the lowermost trunk region over the pubic region or lower abdomen region to the other side of the lowermost trunk region.
