Before you start your project.

I have a drain from my bath that runs along the wall above ground leavel to the soil pipe Are you saying that the entire bathroom groups drainage is above the floor or just the tub? How far above the floor?
This is a major plumbing project that will either involve tearing up the floor and lowering the drainage or platforming the entire room. This project will require all sorts of tools and skills. You will be contracting this out won't you? After you're read the link do you still wish to proceed? We can help but I want you to realize that you're heading into major surgery here. Let me know what you decide. Good luck, Tom
