Hi, is there anything available to reduce a section of soil pipe from the toilet to the stack (4" down to say 3") as looks like a real problem fitting in 1200mm shower tray and boxing in soil pipe in a bathroom 1325mm wide.
or does anybody have any idea how I would build a stable stud wall to encase the soil pipe and shower water supplies
