I would like to know if a toilet could be raised 2 or 3 inches without damaging piping or flange. Is there extentions that are manufactured for this?

We have tried 3 different wax rings since Friday and the dang thing is still leaking around the bottom of the floor. The house is only 3 yrs old. What am I missing here? Looked at the toilet itself for cracks but could not see any......... I would say the more you flush the toilet the more it leaks. It was really bad Friday until we started messing with it now since most of us will not go in there the leaking doesn't seem as bad but we would like to use that bathroom ya know! lol I am so lost now! I hate to have to call a plumber and pay lots of $$$ for something if it's simple and I am just missing it! It seems to stink in there also like urine or something. I have locked the kids out of that bathroom and opened the window trying to keep the smell out of the rest of the house. HELP! :eek:
