Do I break out the flange?
 
Hoping someone is listening as I'm in the middle of the job. BTW, thanks to all who helped my remodel my bathroom last August- it's a work of art and amazing to everyone who sees it that I did it myself.

I just ripped out another bathroom floor down to the josts. The old subfloor was cut around the toilet flange but a piece on either side goes underneath the flange so it can screw in. Do I tuck the new subfloor underneath in similar fashion then put the backerboard on top, or do I remove the flange and tuck the backerboard underneath it also? And if I break out the flange, how do I do it?

Thanks as always- you guys are the best.:)

It sounds like you may need to put the subfloor under the flange and then screw the flange to the subfloor. Are you going to put down tiles?

The backer board can be cut to go around the flange but it does not need to go under it.
The wax ring for the toilet will make up the difference in height. Sometimes if the flange sits down lower than the finished floor you can use two wax rings to make up the difference. I believe that they even sell a taller wax ring for the purpose when someone installs tiles.

Perfect, thanks, just the advice I needed. I've finished the subfloor removal under the flange and notice the flange is not tight to the pipe underneath it. Is it supposed to be, and if so, how to I fix this?

Also, I'm just putting down one subfloor, (plywood), then the backerboard. Right?

Yes, I'm using tile. Wouldn't ever use anything else.

Is the flange PVC or cast iron?

How thick will the subfloor(plywood) be?

subfloor then backerboard - yes that is correct.

It will need to be thick if you are going to put down tile because the subfloor cannot flex or it will crack the tiles.

-------------------------------------
Selecting a Subfloor
What goes underneath your floors is as important as the finish material. Not all types of joists and subfloors are appropriate for all types of flooring.

A ceramic-tile floor needs a solid substructure because subfloors in a new home are vulnerable to settling that can damage tile. Confirm that your tile contractor will follow the recommendations of the American National Standards Institute (ANSI) or those in the Handbook for Ceramic Tile Installation published by the Tile Council of America.

Materials such as vinyl and carpeting are flexible enough to tolerate engineered floor truss systems with larger joist spacings, such as 24 inches on center. For ceramic tile, the Tile Council recommends using joists that are 16 inches on center, a 3/4-inch-thick plywood subfloor, and a 1/2-inch-thick cement backer board or concrete slab. Oriented strand board (OSB) and other porous manufactured boards are not recommended for the subfloor because they absorb moisture and will expand and contract, causing the tile or grout to crack.

Laminate floors are installed to float, meaning that the flooring panel edges are glued together but are not attached to the subfloor. A clear, thin plastic sheet underlayment helps the flooring float freely. Laminate, carpeting, and vinyl flooring can be installed over a variety of subfloor materials, including wood and concrete.

Most solid wood flooring is nailed to a plywood or OSB subfloor over wood joists or a slab-on-grade foundation (solid wood is not recommended for below-grade installations, such as basements). Engineered-wood flooring is either nailed or glued down, and usually can be installed below grade. Some engineered-wood flooring can be installed as floating floors over a wood subfloor or consrete slab. If installed over concrete, the recommended subfloor is either 3/4-inch-thick plywood or 2x4s, and a vapor barrier of either asphalt felt and mastic or polyethylene film is required.

Discuss any room-to-room transitions in flooring with your builder or installer ahead of time, before materials are ordered. Subfloors need to be prepared so that the intersection of different flooring materials is level or at least so that the difference is not noticeable.

You won't believe what the guy at Home Depot told me...
 
Went to buy the tile today and the guy in tile at Home Depot insisted I did not need to lay a subfloor, just the cement board. Insisted. What a moron. I tried to explain the facts to him (I'm laying over wood joists, by the way), and he wouldn't budge. I reported him to the manager.

Subfloor is cut and perfectly under flange.....I'm so proud of its symmetrical perfection, I don't even want to put a potty on it...just let people come in and marvel at the beauty of my perfect round cuts......
