I want some advice on moving a toilet from one position to another position, it means cutting through a concrete floor and extending the pipe, is this the way to do, cutting through the concrete to the depth needed to get to the pipe, and extend it to the place i hv selected, and concreteing it back in, is this what i need to do, anyone that has done this before, all the insight you can give me will be appreciated,
Welcome to the Bunnings Workshop community @Havagobob. It's sensational to have you join us and many thanks for your question.
That's the basic gist of it. You would cut into the concrete to access the waste. Cut and remove the slab allowing enough room to divert the pipe to where you need the new toilet. Adequate fall of the line needs to be adhered to if you plan on moving the toilet some distance. Then you will have to rebuild the concrete foundation and replace the sub-flooring and tiles.
If the new toilet position is on an exterior wall, you could consider a skew trap suite instead of using the existing pipework.
