It's actually required by the International Plumbing Code to caulk a toilet to the floor, and now knowing the reasoning behind it, why would you not want to? It helps to create safety in the bathroom and even provides sanitary protection.
Now with tile, because it's a hard floor covering, you can install the toilet mount into the subfloor, then tile around the mount and then affix the toilet on top of the tile, using grout or caulk to seal the toilet itself to the tile - the actual toilet mount ring though is always installed directly onto the subfloor.
You should absolutely caulk around the base of the toilet for hygienic and cosmetic reasons. The caulk prevents 'other' liquids from getting underneath, and I don't just mean when the floor is mopped; bad aim, overflows, drinking too much the night before, etc.
Your toilet should be fixed to the floor using several bolts.
Purpose of Caulking: Caulking around the base of the toilet can help to prevent water from seeping underneath and can also help to keep out odors and pests. Use the Right Material: Use a waterproof caulk, such as silicone caulk, which is suitable for bathrooms and can withstand moisture.
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.
Meeting Building Codes: One primary reason to caulk around your toilet is that it's code. According to the International Plumbing Code (2012 edition) and the Uniform Plumbing Code (2009 edition), sealing the joint where fixtures meet the floor is required.
Today the method most commonly used by plumbers to fix a toilet pan to the floor is with clear sanitary grade silicone.
Most toilets are white and most bathrooms floors are white. Always chose white. White caulk will give your bathroom floor a seamless integration to the toilet which is what you want for your bathroom. Apart from time that, clear caulk tends to turn into a yellow color with time.
The short answer to the question "should toilet sit on top of tile?" is simple - if you've opted for ceramic tiles, then you should tile them under the toilet, if you've opted for vinyl tiles on the other hand, then you should go with tiling them around the toilet.
Alternatives like caulk strips and sealant tape need more frequent replacement, but spray foam and silicone putty can offer a similar life span in the right conditions.
Using caulk instead of grout in areas where grout is traditionally employed is not advisable. This is because caulk lacks the structural stability and durability of grout. In tile installations, caulk cannot bear the same load as grout, and it is more susceptible to wear and tear from foot traffic and cleaning.
A toilet flange should not be leveled to the floor. Ideally, it should be about 1/4 inch above a finished floor. Installing it level or below the floor can lead to leaks.
Putting caulk around a toilet's base where it touches the flooring can help hold the toilet in place. A more effective way is using caulk with plastic shim wedges. Place the shims underneath the base to steady and stabilize the toilet.
The most common culprit for a loose toilet is the flange or flange bolts. Looking from the front of the toilet, check the flange bolts which are situated on each side of the toilet. If the bolts are loose, use a pair of pliers to carefully tighten the bolts until they are snug.
The answer is yes! Removing the toilet when tiling a bathroom floor is always a good idea. Otherwise, you risk your new tiles' proper fit and seamless appearance.
Toilets should be caulked at the floor.
Water Retention Concerns
Perhaps the biggest argument against caulking is the potential for hidden leaks. Without caulk, it's easier for water from a leak to seep out onto the floor. The problem is visible, so you're more likely to spot it right away and get prompt repairs.

Re: Fixing a toilet to a tiled floor
1. You tile finish then mark the toilet in position and using a diamond blade, cut about 20mm on the inside of your marking. Then chip out that area and fix your toilet down with Goldstar2 or 6 adhesive.
Both provide a long-lasting seal where your toilet meets the floor. Ease of Cleaning: If you want to keep track of cleaning needs, white caulk makes dirt and wear more visible. Clear caulk is better suited for those who prefer a low-maintenance, discreet seal.
Toilet front clearance: Bathroom building code or design practices recommend that toilets need at least 21 inches of clearance in front of the toilet. Opting for 30 inches of room provides a more comfortable space.
