I'm actually in the process of remodeling my bathroom. The toilet had been leaking for a while and when I went to replace the wax ring I found mold everywhere. Stretched back to the wall, up the baseboard and around the shower. I tore everything out... shower, toilet, fixtures, walls and even the ceiling.
I've never done any construction, carpentry, etc, either; but I can work a sledge hammer pretty good.

A friend has been helping me put it all back together, and we're actually installing a custom steam shower. I'm at the point now where I'm ready to buy tile and start painting.
It's definitely gratifying seeing a project come together.
