Rated 1.0 out of 5.0 by Buyer beware The warranty on the package clearly states it is for the purchase price only. I thought this was a great product but beware, it will fail! I installed this ring on 5/26/15 and on 7/9/15 I noticed water coming up through the seams of the vinyl plank flooring when walking next to the toilet. When I contacted the company I was told exactly that, "The warranty on the package clearly states it is for the purchase price only". I was also told by them, "not until recently have we heard of a handful of issues with the coating not adhering to the foam." When this happens it allows the foam core to soak up the dirty water being flushed until it can no longer hold that water and then guess where it ends up. To me this is unacceptable, if my floor had no seams and I was not able to see the water leaking under my floor this could have gone on until much worse had happened. I would not use this product to prop up a dogs water dish, nor would I put any faith in the company that has told me basically,.... we only tell you that we will cover the cost to replace our product if it fails in our why take that chance. If they don't believe enough in there product to warranty damage why should you??? Here is my failed product. July 10, 2015
Rated 5.0 out of 5.0 by After a wax ring failed... I searched for alternatives to Wax Rings, and found Saniseal...I read through hundreds of reviews on this and other sites, and was really hopeful about this product...I could not believe how easy it was to install. And Plumbing is at the very bottom of the things I like to do. I was so pleased, I am going to replace the wax ring on my other toilet, before it fails. I HIGHLY RECOMMEND the SANISEAL..

Rated 4.0 out of 5.0 by Fits Just About Any Toilet Flange Let me start off by pointing out one, very important, thing. To quote the manufacturer "Universal fit: Fits all flanges from cast iron to inside 3 in. and all standard toilets." The reason I point this out is because if you have a toilet flange, with an inner diameter of 3", and you utilize a 3" PVC adjustable metal ring DWV closet flange to repair a broken flange, your inner diameter will now be less than 3". Therefore, this gasket will not fit this application. Please refer to the attached photo to see how this gasket does not properly fit in this applications. If this is what your gasket looks like when you seat it on the flange DO NOT CONTINUE any further. You will need to find a different gasket to utilize. With that being said, this gasket is a nice alternative from the standard wax rings. Starting out with the obvious, this gasket it not made of wax allowing you the opportunity to reset the toilet multiple times without fear of damaging it, is definitely one of the biggest draws to this gasket. If you have never replaced a toilet gasket before and are going to do it yourself, I would highly recommend it. This gasket is extremely easy to install and makes this task seem extremely easy. More times, than not, you will have to reposition the toilet. This gasket allows you that flexibility. Another feature that is nice is it holds the bolts in place while you are seating the toilet. There is no movement, allowing you to position the toilet with a little more ease. Overall this is a good product and offers several advantages over the standard wax rings. Just make sure it is right for you application. November 24, 2015
Rated 5.0 out of 5.0 by Perfect for remodeling. In the middle of remodeling, where I need to pull & reset the toilet everyday. Had been going through a wax ring a day. Did this about 8x before I noticed the Sani Seal hanging next to the wax rings. No more messy, time consuming job of scraping the smashed wax ring everyday. I could have saved a small fortune had I known about this product. Made another trip to HD to pick another one up for the other toilet. Truly impressed by such a simple product. October 21, 2014
Rated 5.0 out of 5.0 by BUY IT! It's probably unusual to get excited about a toilet installation product part, but if you've ever dealt with wax rings (messing it up the first time and have to go back to the store, double up wax rings, etc.) this thing makes it a breeze, especially if you're by yourself. It forms the seal and has the ability to flex in the event the toilet moves or rocks after installation. No mess!! It even holds the closet bolts in line for you when reseating the toilet!! (I know, who gets excited about this?) I guess I do! September 21, 2015
Rated 5.0 out of 5.0 One of my favorites I have had a Sani-Seal toilet gasket installed on my downstairs toilet for over two years now and have not had a single leak. The gasket is constructed of foam with a vinyl like coating over top of it. It reminds me of the foam floats they make for boat ignition keys. If you dropped your keys in the water it would keep them floating. Before installing the gasket you should make sure you've cleaned off any leftover wax from the seal that was previously on your toilet and on the base flange. A heat gun does that job pretty well and a hair dryer might work as well. The first time I installed the toilet I didn't have it properly aligned so the toilet was twisted to the right. Because the seal is made of a foam material with a vinyl coating I was able to remove the toilet, reinstall the seal and then align the toilet properly. If I had used a wax seal I probably would have saved a few dollars but it would have meant wasting my time cleaning the old seal off and starting over and getting frustrated in the process. In a few years if I redo the floors I can just unbolt the toilet and reuse the seal. There's no need to buy a new one. The seal also holds the bolts up, which makes it a lot easier to align the holes in the toilets base with them. A new set of bolts is included in the package. If you're toilet doesn't meet the base flange properly (as in the case of thick hardwood floors) you can stack two seals together with a coating of silicone in-between them to form a thicker gasket. Keep in mind that this product is NOT a gasket for the tank to bowl connection. This gasket is meant to be used to create a water tight seal between your toilet and the flange that is installed in the floor. Long story short, this is one of my all-time favorite products and I have recommended it to friends and family on more than one occasion. November 10, 2015
Rated 5.0 out of 5.0 by Works great, easy to install. After 2 failed, messy attempts to get wax rings and even double wax rings to seal, I found the Sani Seal Toilet Gasket. My PVC toilet flange was approx. 1/8" below concrete surface and the wax rings would not seal properly. The Sani Seal Gasket is very easy to install, and holds the T Bolts in place while you set the toilet over the bolts. The gasket provides a positive seal and no more leaks! Finally after all these decades of messy wax seals that are unreliable someone invented a solution that really works! November 6, 2012
Rated 5.0 out of 5.0 by This seal was our answer of fearless installation of a toilet. My daughter and I watched a TV program about new inventions for the home. This toilet waxless seal was shown and explained. We knew nothing about installing a new toilet, but we decided to do it ourselves. The scary part to us was the wax ring. If you do it wrong...oops it's bad with the wax seal. The price was a little more for the waxless seal, but it was worth it. Yes, we did not do it perfect the first try or the second try - that would have been 2 wax seals right there. We were able to reposition the toilet with the waxless seal without fear. What a adventure it was. Two women watching YouTube - how to do it. And we did it! We feel ready now to put in the second toilet. We saved a lot of money doing it ourselves. We probably would have chickened out without the waxless seal. Don't be afraid...just do it! We give this seal our seal of success. February 10, 2015
