    Waste pipe connection for freestanding bath

    Hi all, I'm currently in the middle of first fixing the waste pipe for my freestanding bath. I've created a mock version out of plastic to determine where the waste enters down through the floor - see photo. I was just wondering is there any minimum length the pipe has to run after the trap...
