As a plumber and sewer man, I have installed a countless number of toilets over my 30 year career. If the floor is solid and level, a toilet needs nothing more than a wax ring and two 5/8" Toilet Bolts properly tightened. If the installer knows what he is doing, a toilet will be sealed and remain water tight and odor free until it has to be replaced. Using any type of caulk or adhesive is just an amateur way of sealing an improperly installed toilet.
