A connection device for connecting a sanitary article to a connection structure which is fixedly predefined on site and which has at least one conduit which is arranged in a positionally fixed manner on site. The device comprises a bearing element having at least one bearing-side pipeline portion, which pipeline portion is arranged on the bearing element and is configured for water-conducting connection to the positionally fixedly arranged on-site conduit and for water-conducting connection to a sanitary-article-side connection point. For the adjustment of the position, in particular of the height position, of the sanitary article with respect to the connection structure which is fixedly predefined on site, the bearing element is arranged displaceable on the sanitary article such that it can be displaced along an adjustment movement relative to the sanitary article.

A fastening system for the fastening of a sanitary article comprising a carrier element, at least one upper stop portion which lies on the carrier element and which strikes against an upper stop of the sanitary article, at least one lower stop portion which lies on the carrier element and which strikes against a lower stop of the sanitary article, and at least one clamping element. At least one of the stop portions is mounted on the carrier element so as to be displaceable with respect to the carrier element, and is connected to the at least one clamping element in such a way that, as a result of actuation of the clamping element, the stop portion can be displaced in a direction of actuation such that the two stop portions can be braced between the two stops of the sanitary article.

A toilet device disposed at a toilet bowl has a main body fixed to an upper surface of the toilet bowl, a toilet seat supported by the main body, and a reflection-type optical sensor disposed at the toilet seat, the optical sensor having a light emitter configured to emit light from a surface of the toilet seat, and a light receiver configured to receive reflection light of the light.
