Hi Folks,

I've adding a bathroom to an unfinished space in my house. The plumber has completed the rough-in and passed inspection. I was going to start on the tile work. Was going to put down backerboard + tile.

I told the plumber I would be putting down backer + tile - so he left the height of the flange to accommodate for this. From what I can tell he has put metal spacers in create the height I need. The screws attaching the flange to subfloor are going through these spacers.

Should I put backerboard and tile around the flange and leave the spacers + current flange untouched? Or should I try to put the backerboard and tile underneath the flange? Do the screws that are currently going through subfloor need to then go through the tile and the backerboard?

I'm attaching a picture - the red is the tile, the grey is the backberboard and the arrows are the current screws going into the flange through some spacers.

Those spacers are just little short pieces of copper pipe. Remove them when you lay your backer board and tile. Slide backer board and tiles under flange and then drill through tile and backer board for screws. Cheep glass drill bits (Home Depot) work great for drilling tiles but they don't last long.

Ok. So I couldn't leave the flange untouched and do backerboard and tile around the flange? Ive seen pictures online if people cutting out backerboard and tile to fit around the flange. Not necessarily to go under it. Thanks

Not a good idea and more work than doing it properly.

Ok. I didn't quite follow your steps. Can I make a hole such that the entire whole is in 1 sheet or do I need to use separate sheets to have semicircle cutouts? Should the diamter of backer hole be 1 inch larger than the pipe or the flange?

Aaaaaaa

Thanks a lot for the pic. So basicall both the hardiback and tile should slip underneath the flange far enough so I could screw them?

It appears there is room for both the backer and the tile, which is very unusual. Before doing anything take out the screws and see if the flange moves up and down like a Oatey Twist-N-Set Twist-N-Set® Replacement Closet Flange | Drains & Closet Flanges | Oatey (http://www.oatey.com/products/drains-and-closet-flanges/closet-flanges/twist-n-set-replacement-closet-flange)

I see purple primer on the closet flange, Bob... pretty sure that baby is set exactly where they want it!

And yes Khabs, place both under the flange, drill through the tile and screw the flange into the floor.

Sorry Mark, been away, see it now and agree. Lets keep in mind that nobody can see this section of tile so you can use smaller pieces of tile and arrange them so that all flange screws pass through a grout line. That cuts down on drilling through tile.
