Sounds like incredibly bad phrasing. Being charitable, we can assume they meant filling in a bathroom sink, not a toilet itself.

in the English speaking world outside the US, the "toilet" refers to the entire bathroom, not the piece of porcelain. This also explains why "use the toilet" is considered crude in the US but not outside. In the US it refers to the physical act of defacating, but elsewhere it is equivalent to "go to the bathroom"
