For me i find that both types of installation work equally well.
Height of toilet flange above finished floor.
By top surface i mean the surface that the wax ring sits on.
In this illustration the flange is set just above the floor.
This typically allows for almost any type of wax ring to be used and still ensure a good seal.
Ideal height of toilet flange.
If the flange is placed too high it runs the risk of making the toilet wobbly.
It s easier to get your flange flush with the floor if you first lay your flooring before you install the flange.
A wax ring will need to be added and this amount of space allows for the wax to fit snugly.
Purchase a new one.
The perfect height for the toilet flange is to be the same level as the finished floor.
The optimum toilet flange height is approximately inch above the floor to achieve the best seal and overall fit.
If you recently tiled or changed the bathroom flooring the flange height is likely less than optimal.
The recommended height is higher than the floor.
Remember this option involves placing the underside of the flange above the finished floor.
If the previous flange is too low purchase one that is designed to sit on the finished floor and provide the optimum toilet flange height.
Height of toilet flange to finished floor jeff the flange should be installed so that the underside of the flange is resting on top of the finished floor.
To get the necessary clearance from the floor you can add a toilet flange.
The correct height for me is just above or even with the finish floor.
This will result in the top surface of the flange being approx 3 8 above the plane of the finished floor cast iron flanges and pvc abs flanges are approx the same thickness.
If you ve already laid your flooring and the toilet flange is too high or unlevel there are a few things you.
For those that don t already know the proper toilet flange height is when it s flush with the finished floor.
If the toilet flange is at the incorrect height it will cause problems with the toilet connecting onto the plumbing.
