im trying to put a new shower room into a large cupboard, 1400*1850 (although i can nick a bit from room next door to 1400 *1850 max) i need to run the toilet across to soil pipe minimum run from new toilet would be 3000, but might be better at far end so 4850. the joists go wrong way so have to run overland is this possible or hated mecerator? any advice on how to do it with taking least room.
