- Reviewed in the United States on January 24, 2025Size: 1/4" - 1"Style: Extender KitVerified PurchaseI’m a bit surprised that there aren’t a lot of YouTube videos on this particular product. Yes there is one by the owner and now they’ve been purchased by Oatey. But this is a code approved way to attach your toilet to the floor if you have unusual situations. I suggest if you buy this, find the YouTube from the owner and watch it, there’s a couple DIY guys that have put out videos, but I personally don’t think they did it correctly. This adapter will work in any situation and I wish I knew about it 15 years ago.
Anybody who has set a lot of toilets knows that when you pull the toilet off, it’s unfortunately usually a surprise. And I bought a couple of these for when those situations arise. This is a great product, quality parts all the way around, even the six screws that are included are all stainless steel. Like I said if you’ve got an unusual situation, or a floor that wasn’t set right, then give this a shot. I think you will be satisfied.
- Reviewed in the United States on June 12, 2024Size: 1/4" - 1"Style: Extender KitVerified PurchaseUsed the adjustable spacers to level the floor flange to my new ceramic floor. Worked great with absolutely no leakage. Easy to install, great value
- Reviewed in the United States on March 21, 2025Size: 1/4" - 1"Style: Extender KitVerified PurchaseGreat fix.
- Reviewed in the United States on October 11, 2023Size: 3/4" - 7/8",Style: Extender KitVerified PurchaseI literally never write reviews but this thing was a life saver. Had a leaky toilet in my house so I had to remove it, only to find the guys who redid our house stacked 3 wax rings into the old flange below the new tile and screwed the toilet into the sub floor. This thing really did the trick. I was skeptical to be honest, being a union plumber myself, and had to use a wax ring instead of the rubber gasket since the old flange was a super old lead bend, but this worked like a charm! Super easy install anybody could do it
- Reviewed in the United States on September 5, 2024Size: 1/4" - 1"Style: Extender KitVerified PurchaseThis Oatey Flange Extender kit worked great for a slab on grade where the original flange was cast 3/4” below top of slab. I did have to buy an additional set of spacers for my application, but it turned out great and I didn’t have to chip up the slab. Used the wax ring method instead of the foam for the seal. Secured it to the slab with Tapcons. I’ve never been this excited to set a toilet, but that can wait until tomorrow.

5.0 out of 5 stars Did the job, great product, easy DIY
Size: 3/4" - 7/8",Style: Extender KitVerified PurchaseI am not a great home handy man and this product made the toilet install easy. Our tile floor had been installed since the last toilet flange so it was recessed. This product made the replacement toilet super easy to do, leak free without guessing on two wax rings.

Size: 1/2" - 5/8",Style: Extender KitVerified PurchaseUsed this for two different toilets in the past two years. Very easy to install and adjust, no leaks whatsoever. 10/10 a great product if your existing flange sits too low.

5.0 out of 5 stars Works Great!
Size: 1/4" - 3/8"Style: Extender KitVerified PurchaseI replaced 3 toilets in my home. They had had tile and hardwood added to the floor and had been leaking because of the poor seal between the plumping pipe and the toilet flange. These kits did the job. Easy to install.

5.0 out of 5 stars Fantastic product!
Size: 1/4" - 1"Style: Extender KitVerified PurchaseI’ve had this installed and in use for over a month and have been problem free.
Our toilet flange was 1/2” below the tile and original toilet was installed with 2 sandwiched rubber donut/seals.
Installed new flange and a spacer over the existing flange to bring up the height a d installed a new toilet with no leaks or rocking.
Very happy with this product and fully recommend for all the weekend handymen out there.
- JonathanReviewed in Canada on April 3, 2021
5.0 out of 5 stars Piece of mind
Size: 1/4" - 1"Style: Extender KitVerified PurchaseIt worked perfectly. Nice quality. Flange was installed on plywood but tiles were higher. This raised it half an inch. There are cheaper ways but this, with the funnel and seal, are reassuring.
