Toilet flange is 2" above baseboard

[norpus]

Hello,

Recently I have tiled my bathroom and removed the toilet to tile under it. When I have replaced the toilet it wobbled and leaked. I have removed the toilet again and noticed that the old flange was bent. Also tt was not secured to the baseboard. It was an old brass flange and I have removed to replace it but if I bring the new flange level with the floor I will have a 1.5 " space between the flange and the board. There is a 1.5" layer of concrete on top of the baseboard.

Do you recommend to use concrete or mortar to build a platform for the new flange, and screw the flange into this? Do you have any other recommendation on how to secure the flange to the baseboard?

Thank you,

If you have access under the floor transition the cast iron to pvc or use a pvc repair flange for cast iron. Be sure to secure the flange to the floor.

Thanks, but if I secure the flange to the floor board it will be 1.5" below the tile level. I believe the flange should be flush with the floor. I just not quite sure how to build it up, should I use mortar or concrete? Also, the drain is not cast iron but brass, I can just solder the new flange to it, if I can purchase a 3" brass flange.

Thanks again for your help!

the flange should be flush to the floor. if you have a concrete floor you can build it up with hydralic cement. if it is wood on a crawl space you will need to build up the floor
