This is actually an important matter to fix a loose, rocking toilet in the bathroom. If a toilet is loose or wobbly and not leaking on the other hand if a toilet isn’t fastened to the floor that may create trouble in future. So it is better to solve the problems where this guide will be very helpful.

Toilets generally rock reason for they are not resting the flush against the floor. Under the toilet base sakes around the toilet flange which attaches the toilet to the pipe (drain). If the flange is higher-a little bit than the adjacent flooring then the toilet becomes slightly raised in the centre and approving it to rock.

Such a kind of problem can increase over time, like when the contiguous floor settles a bit or while the caulk hardens. So you can steady your toilet by shimming beneath its base. Before that, make sure used bolts at the bottom or base of the toilet are snug.

For this strategy, the great shims are tiny and plastic with ridges helping the shims retain in the proper place. They are usually sold at hardware stores, home centres and restaurant supply stores.

Wood shims can consolidate over time and vulnerable to damage moisture so they are not recommended.

Required tools and materials:
Plastic shims
Utility knife
Tile and tub caulk (as colour matching)   
Rag or paper towels

With a small wrench or a pair of pliers, check the flange bolts entire side of the toilet. If you notice a bolt is loose, then slowly tighten it until it is snug. Inspect the other bolt to make sure this is similarly snug, and then check your toilet for rocking. If it remains rocks, approach with shimming the base.
Explore The Leaks

Check the base of your toilet, and find out any gaps between the floor and the toilet. If may boost to rock your toilet from each of the sides. 

Probably a small space can be the emergence of the problem. If the gaps are so small, endeavour to slide a shim beneath the base to observe how far it goes in.
