Gaps between the toilet base and the floor can be problematic in so many ways. 

Can a loose toilet lead to the rocking of the toilet flange? Can a loose toilet cause leak? These questions might have crossed your mind. 

Well, all of them have one commonality and that is gaps between the toilet floor and toilet base which leads to fix a wobbly toilet shifting and other discussed problems. Thus, one must fill up the gaps no matter how small they are.

Inserting the shim is just the tip of the iceberg. What lies ahead is slightly trickier. The gaps that you identify between the toilet base and floor might be different and so the shim that you use must be a perfect filler to bridge these gaps otherwise the connection would fail, leading to the toilet shifting a lot.

Thus, to prevent further rocking like springs, one needs to try inserting the shims in different ways until one gets a steady and leveled toilet.

To sum up, try a variety of positions. Check to see if the toilet rocks or wobbles on any side by sitting on it every time you insert the shim in a gap. Once inserted properly, you must have a stable toilet.

Cut the shims.

When you insert a shim in a gap that you identified, you may encounter that there is a part of the shim that is left out and needs to be cut.

So, after getting the right inserting position, cut off the excess with the help of a utility knife. Be cautious while trimming as you may damage the flooring or hurt yourself.

Apply caulk around the toilet.

Caulk is a material used to seal the gap bridged by way of a shim. It gives a finished look and prevents water and crud from seeping into the gap.

To secure the shim, apply a thin layer of caulking material to hide the shims and properly seal the gap between the floor and toilet base. You can smooth the layer of caulk by way of your fingers but clean your hands with liquid hand soap, towel or paper rag as it hardens quickly.

Because of the anti-seepage property, it possesses, it does not allow water to escape and one cannot essentially detect a leak if it is sealed completely. So, you can keep the backside of the base caulk free.

Let the Caulk Dry.

Once you have applied the caulking material and smoothened it to your satisfaction, allow it to dry by leaving it alone for some time. And, there you have your wobble-free toilet ready for use. 

So, say goodbye to wobbly toilet tanks and bases and say hello to your brand new toilet.

However, if you still have a wobbly toilet, then the problem goes beyond inserting shims and fixing flange bolts. This could be because the rings that affix the flange bolt could be broken or corroded leading to a loose grip or a rocking toilet base.

Further, if because of this the bolts loosen up and would not tighten up, then you will have to repair the flange using a repair kit or replace the toilet altogether to have a steady toilet. If for some reason, the wobbling comes back, then it is best to look for professional help.

In any case, your toilet can become wobbly any time and thus, the most common bathroom storage ideas are to store these utilities at all times.
