The International Plumbing Code requires caulk around the base of a toilet. You must use 100% silicone caulk where fixtures meet the wall or floor. Here are a few of the primary reasons it's required, and you should take the time to properly seal toilets above and beyond basic code requirements.

Your toilet should be fixed to the floor using several bolts.
Porous materials, like travertine and other natural stone tiles, often require sealing, especially in high-moisture areas like showers or tub surrounds. Conversely, for porcelain and ceramic tiles, which are highly resistant to water, sealing may be optional, especially for those that have a glazed finish.
Waterproofing your floor is another important step in making your bathroom watertight. Assuming your subfloor is in good shape and level, your next step is waterproofing.
Toilet Seal Replacement

Water damage is one of the most common and costly issues homeowners face. When water seeps through the gaps around the toilet base, it can saturate the flooring materials, weaken structural supports, and even lead to mould growth. Over time, this can result in extensive and expensive repairs.
Toilet lid closure prior to flushing is believed to mitigate cross-contamination.
Today the method most commonly used by plumbers to fix a toilet pan to the floor is with clear sanitary grade silicone.
Caulk prevents smell
If you don't caulk a toilet to the floor, you could find yourself smelling leftover residue from smelly mop water, tub water, or even worse, the remnants of your son's potty training.

Most porcelain tiles won't need sealing, as they are naturally robust and offer water resistance. However, if you have polished porcelain or other porous tiles they must be sealed to stop water from entering and damaging the tile. Unsealed tiles can stain, and attract dust and dirt which can be difficult to clean.

A toilet wax ring, located at the bottom of the toilet around the sewer pipe, is a sticky ring that ensures that your toilet seals around the sewer line drain pipe. It ensures that when the toilet drains, all the water goes down the pipe and not under your finished floor into your subfloor.
A loose toilet can be caused by several conditions. It could be a broken flange, which is the mechanical connection where the toilet is mounted to the plumbing on the floor. The floor could be deteriorating and unstable, and floor variations could cause the flat base of the toilet to rock on the irregular surface.
