My mother wants to move her seperate W/C from the end of the kitchen which is against an exterior wall. It will be put in the bathroom which is at the opposite end of the kitchen in the middle of the house. There is a solid concete floor all the way through each room. Is it possible due to the waste pipe, which i imagine involves digging up the concrete floor. Has anyone had this done with a ball park figure for cost. I would think it would be a lot of hassle for her. I'm loathe to suggest Sani flo toilets as going by the forums they can be trouble and expensive to service. And plumbers hate them.
