I wish we would have found this sooner. After removing the toilet numerous times because it was leaking and spending a lot of money on different plumbing parts. I bought this and finally it's not leaking. I recommend this highly. We are redoing out master bath. My husband said order another one just like the last one. So I did. It would have saved us so much aggravation and money if I had bought this one to start off with.

The toilet is very wobbly and is already leaking. I'm replacing it with the tried and true wax seal.

So many positive things to mention! First, this is BY FAR the best toilet seal I have used (many rentals). At the end, I will explain the problems I have had with other toilet seals.1. the lowest part of the seal inside the pipe is just over 2.5 in -- which is exactly what the toilet horn is so there is no fear of it restricting flow. The upper part of the seal going inside the pipe is slanted and increases to over 3 in, so no chance of water splashing up past the outside of the seal if you plunge the toilet.2. the silicone seal COMPLETELY covers the black foam (even if you have to use both- see photo- and this is before black foam is compressed). So the foam is completely covered by the grey seal.3. the design of the top (which connects to the horn) is best of all! Almost all horns are 2.5 inside dimension/3.5 outside ceramic at the end (wider higher up). This seal has a top inside edge of 3.4, so if the horn is perfectly placed, it will slide up the outside of the horn and create a perfect seal. But rarely is one able to position a toilet perfectly. And that is where this is so great -- you can position the horn up to 1/2 in in any direction! And it is rare that you miss by half an inch if you rely on the bolts to direct you. But this is where it might get hard to visualize.If it is off-center, the horn will be too far outside the center hole on one side, and on the other, too far inside the center hole. But you can still form a good seal. This is where the design of the top comes in.You can see from the side photo, that the top has a kind of lip that first extends up, then curves inside. The width of this curve is 1/2".If the horn is 1/2" off, the horn will push the curved part of the lip inside on one side. On the other side, the horn will slide inside the hole with a gap between the end of the seal and the horn -- BUT when the toilet is seated, it will push the down the edge around the circle -- again a good seal. And I even think that in most cases, when the horn is pushed down, the silicone might shift and conform to the horn.Before I sealed the toilet, I tried pushing the seal onto the horn in different positions -- and that is what happened -- the silicone is flexible enough that it shifted position to one side and allowed the horn to be fully encased in the seal. Great!!!I have a Nidage boroscope, and you can see how it shows the position of the horn and seal.One reviewer commented that it wobbled -- the instructions warn about this because the foam needs to compress itself -- if you used the correct foam, tightening the bolts should take care of it. Of course, no too tight. And unless you have a perfectly level floor, any toilet will wobble until you add shims.Just to share my experiences with other seals:The green foam ring seemed to be fine -- until I had to remove that toilet -- it had absorbed water and the subfloor was starting to deteriorate because water travels (in this case outside the green foam and onto the subfloor).I tried the Korky, but unless the toilet horn is exactly -- and I mean exactly -- positioned in the center of the red silicone, water will go into the black foam -- and again it is not closed-cell, so it will leak outside the foam.I was going to try the Fernco but the design reduces the pipe to 2-3/8 max. Also, bad comments about glue not sticking.

I have a commercial building and the floor is all concrete (under carpet, tile, whatever). So, the flange for the toilet was installed and then the concrete was poured around it to the same height as the flange. This was the third time I've taken that stinking toilet out (pun intended). It turns out the flange they put in there 1) Restricted the flush to the point where the toilet routinely needed to be plunged. 2) Is glued in there or something. It's some kind of super hard, relatively brittle plastic. I broke it trying to get it out. I ended up just chiseling the rest of the lip off and leaving the rest of the flange still in there. So, this thing is sitting on rough concrete (they didn't even scree the concrete under where the flange lip was) and on what was left of the flange without the lip. I reasoned that, since the rubber cone went down past the foam rubber rings they give you, it would work. I was right! That toilet is better than it ever was!! (We've had the place since 1993.) Hardly a great installation, but it worked like a champ! The important part is obviously the rubber to the bottom of the toilet seal. The foam rubber rings just push up on that rubber to adjust for height and push the rubber against the bottom of the toilet. Not only doesn't it leak even a drop of water, but it also flushes MUCH better! The rubber cone, apparently, doesn't restrict as much as the hard plastic flange did. Because you're probably curious, I had to drill two holes in the concrete and use two concrete anchors with washers and nuts to put the toilet back on and hold it down. Worked perfectly! Highly recommended for pretty much ANY situation!.The one thing: With one foam rubber ring (really good instructions), it didn't match the instructions. With both foam rubber rings, as per the instructions for "level with the floor" installation, the toilet was way off the floor and scary because I didn't want to tighten it down that amount of distance for fear of breaking something. My recommendation would be for them to provide 3 foam rubber rings - one as it is now, and two more, half the thickness, for better adjustment potential. I ended up cutting one of the foam rubber rings in half so it was half as thick. It worked, as I mentioned, but it was a real pain and it wasn't pretty.

You have to be crazy to still be using a wax donut these days!This gasket will allow you to remove the toilet multiple times and replace it without damaging the seal!Honestly, I don't ever see this gasket ever going bad unless it dry rots and seeing how its made out of silicone I don't really see that happening. So its probably the last toilet gasket you'll ever buy in your lifetime 😉

Just installed this with a new toilet flange level with the floor. Saw other people's review about the toilet being wobbly. When I placed the new toilet with this gasket with one foam underneath on the new flange I was afraid it may not work because the toilet was sitting above the floor and it wobbled. However, once I secured the toilet bolts, toilet stopped wobbling as it came down to the floor flush. It's been a few days and no leak!! Highly recommend!

Pretty Good.

Product worked, after installing my toilet was wobbly. My boyfriends a plumber so I don't think it was due to installing. Product might have just been too large, bummed cause it was a good idea for us.
