The most common toilet leak is caused by a deteriorated flush valve (flapper) at the bottom of the toilet tank. If the flapper does not seat properly, water will leak into the toilet bowl. Often this leak will occur without being heard.

Bathroom leaks are very common and homeowners might be tempted to just ignore the problem, but this is a serious mistake. A leak that is not repaired promptly could result in a hefty repair bill at a later date, as water leaks often cause significant structural damage to homes.
If you're installing a new floor, pedestal sink, and toilet, you should install the laminate flooring first so it's under the sink and toilet. Because laminate flooring floats above the sub-floor on top of underlayment, it will expand and contract slightly with the temperature and humidity of the room.
When a toilet leaks at the base, with water pooling on your bathroom floor, it's typically due to the failure of the wax gasket that seals the toilet to the floor. This seal should make a watertight connection between the toilet and floor. A leak often means that the wax seal may need to be replaced.
A silent toilet leak (the one you usually can't hear) can waste around 500 to 800 gallons of water per day! The ones you can hear will waste much, much more. Such waste can typically be attributed to a faulty water level adjustment or a leaky flapper.
A toilet that is not level or centered could continue to leak water. Tighten the bolts with a wrench and replace plastic caps.

Your homeowners insurance policy should cover any sudden and unexpected water damage due to a plumbing malfunction or broken pipe. However, most home insurance policies exclude damage to your home that occurred gradually, such as a slow, constant leak, as well as damage due to regional flooding.

A best practice is to install the toilet flange on top of the finished floor. If you install the toilet flange flush with the finished floor, or even below the finished floor, leak paths will form, because the flange won't be at the correct height to accept the horn at the bottom of the toilet.
Toilet manufacturers have weighed in on this discussion to recommend that you place tiles beneath the toilet flange. What they recommend is to put the flange on top of the tile, ensuring that the bottom of the flange touches the surface of the tile.
