Does a toilet flange need to be flush with the floor?
5 Answers. The toilet flange needs to be on top of the finished floor. Meaning the bottom edge of the flange needs to be on the same plane as the toilet. So if your toilet sits on the tile, the flange needs to be on top of the tile too.
Does toilet flange go inside or outside pipe?
This toilet flange is designed to glue on the inside of the pipe or expand inside the pipe. Leave the old toilet flange right in place and glue on the new one at the right elevation for the floor, if it’s plastic. The flange should be sitting with the bottom edge flush with the top of the floor.
Can toilet flange be lower than floor?
In a typical toilet installation, the floor flange that sits inside the drain opening below the toilet should be positioned so that its bottom surface rests flush against the finished floor, or no more than 1/4 inch above or below the floor.
Does a toilet flange need to be glued?
This toilet flange is designed to glue on the inside of the pipe or expand inside the pipe. The bottom of the flange needs to be sitting flush with (or not more than 1/8″ above) the finished floor or else the toilet will rock. The flange should be fastened to the floor. Dry fit the toilet to make sure it doesn’t rock.
How high should a toilet flange be off the floor?
Optimum flange height to aim for is 1/4 inch above the finished floor. This typically allows for almost any type of wax ring to be used and still ensure a good seal.
What if toilet flange is not level?
The toilet should sit on the floor over the flange and still have a little room above the flange for wax to make the seal – it must be shimmed to sit flat, if it rocks (before you install the wax ring). If the toilet sits ON the flange, you won’t be able to keep it sealed properly.
