Toilet Flange Height

Hello,

I'm roughing in a toilet to a new bathroom. The finished floor is not installed.

When roughing in a toilet flange, is it best to mount the flange directly on the sub floor? I'm wondering if I should leave a gap to compensate for the tile thickness.

Thanks,
Steve

All toilet flanges should be installed and screwed/secured to the finished floor.

Never the sub floor. The screws can penetrate through the finished floor to the sub floor but the flange needs to be sitting on the finished floor.

I would leave the flange off until the flooring is finished. Otherwise it becomes a challenge to fit the flooring around the pipe under the flange. It appears that the Grand Canyon is getting larger.

Yes, the canyon got a little bigger.

I was looking at the new Code Chek book at Homey and it said the flange must be installed flush with the finished floor. I just laughed all the way home. Who writes those things, anyway?

Yes, the flange goes on top of the finished floor.

If there's tile, I usually install a plywood donut the thickness of the tile and screw through flange, donut, and subfloor.
