I got a “Closet Flange Extension Kit” from Home Depot and it has 2 rings. One is ¼ inch and the other is a ½ inch; so basically I want to know which one to use.

The current/original flange that is installed on the sub-floor is level with the top of the tile. The tile is just that 12” square floor tile that Home Depot sells that’s under a buck a tile, it’s not porcelain, marble or anything fancy. So I’m wondering which extension ring to use.

I measured a Flange’s thickness to see what I should be off the floor, and it looks to be 3/8 inch thick; but the Kit does not include one of that thickness.


Thank you in advance.

I'm having a little trouble understanding your problem. If the flange is level with the sub floor and you are installing asphalt floor tile that's about1/8th" thick why would you need to extend the flange at all. Simply install a wax ring with a funnel and set the toilet. It's much better to have the flange a little below the finished floor then above it. Good luck, tom

Sorry, not the asphalt tile, I meant the cheap ceramic (I thing it's ceramic; you put down cement/mortar and set them on it, and then grout between the cracks) tile. I forgot about the peel & stick ones.


If what you are saying is OK, then I'm set.

But I always seen those Flanges (And may I'm using the wrong word) sit on top of whatever you have as the finished floor.

I did a search on line, and I think the proper term is “Flange Hub”. The thing that screws on to the floor that the 3” ABS glues into. (Picture of what it looks like here: http://doityourself.com/store/9650714.htm )


Thanks.



But if I leave it as it is, I got a ¾ inch gap between the bottom of the toilet and the flange. I'll have to measure the thickness of the wax ring I got.

A 3/4 gap's too much. If you a have 1/2 and 1/4 Closet Flange Extension Kit why not use both to take up the 3/4" space. On another note if the flange that you have pictured has a deep enough throat and you can get a inch or so over the stub-up to prime and glue it you may be able to set that flange on the finished floor. Which way will you be going? Regards, Tom
