I can’t tell you how many times we’ve seen this plumbing mistake made by home owners.
Toilets sit on a toilet flange, the flange is secured to the subfloor, the waxring seal goes between the toilet and the flange.
The problem when the perimeter of the toilet is sealed with caulk to the floor is, you’ll never know when the seal is worn out and in need of replacement.
When you flush the toilet and water comes out from under the toilet, the worst thing you can ever do is caulk it sealing the water in. When you do this, the water sits and soaks into floor, eventually rotting your floor away.
Another sign that you have a bad toilet seal is a water spot on your ceiling below a bathroom.
Leaking water can be very destructive, don’t ignore it or cover it up, fix it to avoid a more expensive repair down the road.
