Question Securing Toilet Flange to Tile Floor

I have just tiled my basement bathroom, and am installing my toilet on the floor. The flange is sitting on the floor (the top is not flush)

My questions are:

Should I cut the tile back so the top of the flange is flush with the floor surface?
Do I have to secure the flange to the floor with screws or PL200 adhesive? Or is just having it secured to the sewer pipe (embedded in concrete) enough?

Hi ash-n-ali,
Welcome the the DIY Forums.

The flange should be fine as it is as long as the surface of the flange is no more than 1/4 inch above the surface of the floor.

The flange(cast and plastic or PVC) must be secured to the floor with screws. You will have to drill through the tile to secure to the wood below. If you have concrete below the tile, you will need to use Tapcon screws and a drill to secure to concrete. Make sure you purchase the correct size drill bit for the size of Tapcon screws you use.

Securing the flange to the floor with the screws keeps the toilet from rocking and breaking the flange off the drain pipe.

Good luck with your project and reply back if you have further questions.
