I am trying to install a toilet flange into two bathrooms.

The toilet flange that I purchased appears to allow me to screw it to the floor? Is this typically done? I've searched on the internet and I really can't find a good set of directions for installing a toilet flange.

Thanks!

Frazwood - TO set the toilet flange , Here is the steps to do it :::#1- Get a rule or tape measure and where you are going to have the toilet , measure out from finnished wall - 11 1/2 "( IF you dont have finnished wall up yet then measure out from STTUDED WALL 12" ( NOTE - THIS IS FIGUERING THAT YOU ARE GOING TO HAVE !/2" SHEETROCK WALLS) #2- get a center mark both ways( A CROSS ) , Take a protractor and make a ( 3 1/2 " ) circle, #3- Cut the hole on a 45 degree angle{ FROM TOP EDGE TO BOTTOM SIDE OF FLOORING< DROP FLANGE INTO HOLE <TO SEE IF YOU NEED TO TRIM IT OUT MORE #4- IF flange sets all way down to floor ,then rotate the flange till the sloot on each side are stright across from each other . The anchor bolt slots are wider where you put the anchor bolts in at then gets narrowl. Where it changes from the wide to the narrowl slot - you want the narrowl to be right stright acropss from each and the anchor bolt won't come out, Hold the flange in place and take some 1 1/2 to 2" wood screws,{ FOR COUNTER SANK HOLES in flange and put all four screws in the flange and set screws FRIM in the holes that are counter sunk into the plastic,:: Get the wax ring with a horn on them ( It's a PIECE THAT FITS DOWN INSIDE THE PIPE <SET THE ANCHOR BOLTS JUST A LITTLE PAST WHERE THE SLOT GETS NARROW, {STRIGHT ACROSS FROM EACH OTHER } YOU are now readdy to set the toilet in place, have someone to watch and make sure bolts are started threw the holes in the bottom of the toilet, set down then sit down ot the toilet and rock to get seated down all the way, now finish by putting on the bolts the washers and nuts,(snug) NOT REAL TIGHT ) both nuts ( NOTE ( THEY WILL BE A 7/16 ) SET down on toilet again and rock easly then finish tighting down the nuts on the anchor bolts

( DO NOT OVER TIGHTEN AND CRACK THE BASE FLANG OF THE TOILET)

Hey all...

FBE gave you great detailed instructions!

But if only installing the flange and pipes are in place already, be clear that tile gets installed first if possible, then the flange gets set so it sits ON TOP of the tile.

Line up the slots in flange to accept the toilet bolts and then mark out the holes in tile with pencil. Then you want to drill the tile with 1/4" masonry bit and set anchors (see pic... comes as an anchor kit WITH the drill bit... ;) ) and screw the flange down firmly through the tile and into the floor below.

Then from there... follow FBE's advice on setting bowl. I added a pic. Of the horned wax gasket.

Good luck... MARK

FBE did a great job. You have not told use what materials you are using, is this all PVC or cast o what? In all cases the flange does get screwed into the floor because the floor carries the weight of you and the toilet, not the flange. The flange solely makes and airtight seal and can not be moving around so the screws take care of that. Your flange should sit on top of the finished floor but can also be flush with the finished floor. Anything deeper than that you'd need an extra thick ring, a spacer or in a pinch a double ring which I do not recommend. Only oher measurement to take is to the side of the finished toilet but if this is a replacement this measurement is probably good already. Your center of the drain to the side walls, vanity or shower must not be less than 15". Good luck, Bob

Thanks FBE and everyone else!

I apologize for the lack of details in my original post...

I am installing two toilet flanges. The first is a replacement of an existing toilet, although I have removed virtually all of the old cast-iron plumbing, so it's a lot like installing an altogether new flange (I did place it in the same location). The second flange is to be located in a room that I am converting to a new bathroom. I am connecting both of these into new PVC waste/vent plumbing.

We have tiled around the toilet flange, rather than placing the toilet on the tile. I watched a video online that was very specific about placing the flange on the cement board. Given what is stated above, this seems OK (perhaps, though, it would have been better to put it on the tile)... and it seems like I should screw the flange into the floor, so I'll do that. Thanks!
