 Raising the Toilet
Author: PinchedFinger

I'm going to tile the bathroom floor and probably raise it about 3/4 of an inch. Will the toilet still fit the old flange or do I raise it too?

it is called a closet flange extension kit. different companies make different styles but they all do the same thing. if the kit comes with steel closet bolts, throw them away and use brass bolts and nuts.

Not an expert but I thought I would throw my 2 cents in. I do a lot of tile work and my most recent job was a bathroom; typical 35 year old pink bathroom to be exact. By the time I was done with the floor, there was "exactly" a 1/4 inch diff between the old brass flange and the top of the new tile. Not being a plumber, I grabbed a typical extender kit (2 of the kits to be on the safe side) from HD which included a seepless thick wax ring. Tried it and it didnt get me the height I needed. Ran out to HD again and I purchased a PVC flange extender (not in the same area as the extender kit). Problem was, the original holes for closet bolts and PVC extender did not match exactly. I then had to drill 4 new holes in old brass flange (brass drills easily) to accomodate the new PVC extender (old flange and PVC extender get screwed together). Ran alot of silicone on bottom of extender and screwed on top of old flange (only use stainless or galvanized screws). I then used thicker seepless wax extender kit and it worked like a charm. I only had to extend a little more than a 1/4 inch, so you may want to get multiple PVC extenders(but please verify that more than one PVC extender can be used). Good luck. By the way, don't caulk all the way around the bottom of the toilet after installed...just the front half(want to be aware of wax seal failing by water leaking onto floor and not to lower floors). It is my understanding that caulking at the bottom of the toilet is code in some states. Could any experienced folks exlplian why? I have heard that it has to do with reducing bacteria at the joint, but I dont buy it. I think a toilet looks fine with no caulk but others insist on it.

I've found that the extention kits that have the rubber seals in between each layer are far better than the ones that require you to apply sealant from a tube, they're made better.

Make sure to purchase 1/4" brass closet bolts if the kit doesn't have them included.

Thanks for all the input. It's nice to know what to expect before you start and how to fix it.

somogyic the reason for the caulk is as you say sealing up that foul area. But,a second reason is to keep that flange from getting wet and rusting out. Those sheet metal stamped flanges on pvc and abs will rust out real fast if they get wet from water on the floor. The water on the floor doesn't have to be much it could be from mopping the floor or a kid in the tub.

Why it is required is immaterial. The inspectors want the entire circumference caulked and who is going to argue with them about it, regardless of any "leak detection" logic?

I hear ya HJ! I'm a little nutty about the need to know "why" about things. I have had tile clients ask "why" when caulking around the toilet and I can never can give an explaination. Kinda bothers me that I dont have the answer.

I would think that one reason for caulking the toilet at the floor would be for sanitary purposes to prevent any 'accidental' runs, drips or leaks from going under the toilet.
It can create an unbearable stink...
