I want to move the toilet to the far side of the bathroom

On a slab this can be a real task. You will need to cut open the concrete, dig a trench and relocate the pipe. However, this could just be the start because drainage slope may not work, venting may need to be moved, water relocated. Working on a slab is possibly the most difficult relocate project.

More details please! Cement slab or floor? How far" Type of pipe material ? How is the toilet vented and will the vent have to move also? Do you have the necessary tools and plumbing skills to do the job? Let me know, Tom
