Our toilet bowl needs to be replaced, as it is cracked. This toilet bowl is about a year old and it has not been screwed onto the floor because there are two pipes running under it (water and gas). The old toilet bowl was in the same place and it was always completely steady, so we never noticed if it was screwed down. From the photos of the pipe system, the toilet needs to stay where it is. Question: Is there a way of fixing the toilet bowl to the floor without screwing it down?
