Toilet Flange Height Above Finished Floor

For me i find that both types of installation work equally well.

Toilet flange height above finished floor.

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. It s easier to get your flange flush with the floor if you first lay your flooring before you install the flange. This typically allows for almost any type of wax ring to be used and still ensure a good seal.

Ideal height of toilet flange. In this illustration the flange is set just above the 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. There does not seem to be a consense of opinion when it comes to even with the floor or just above the floor.

Optimum flange height to aim for is 1 4 inch above the finished floor. If the flange is placed too high it runs the risk of making the toilet wobbly. If you recently tiled or changed the bathroom flooring the flange height is likely less than optimal. To get the necessary clearance from the floor you can add a toilet flange.

A wax ring will need to be added and this amount of space allows for the wax to fit snugly. When installing the toilet flange you need to check that it s the correct height and is also perfectly level. The recommended height is higher than the floor. If the toilet flange is at the incorrect height it will cause problems with the toilet connecting onto the plumbing.

For those that don t already know the proper toilet flange height is when it s flush with the finished floor. The correct height for me is just above or even with the finish floor.
