    So much better than a one-use wax ring!
    5 out of 5 stars
    So much better than a one-use wax ring!
    I stumbled across this somehow and bought one because one of my toilets was letting gas leak from the toilet main pipe and I need a new ring. For some crazy reason, wax rings endured for generations. Even though they're only usable once, they're unbelievably sticky and difficult to work with. If you make a mistake putting the toilet into place with a wax ring, you may have to buy another one if you squish it into place and make an error. With these squishy, foam rings, you don't have to deal with any of that. As you see in my pic, there are plastic washers which hold the screws vertically for you set the toilet into place. With a wax ring, the screws had to be held in place by a helper, which isn't always possible given how tight toilet spaces may be. It's simply amazing but it's weird that we had to deal with old-school wax toilet rings. Try one and you'll never use wax rings again.

      This product offers a hassle-free solution compared to traditional wax rings. The installation process was incredibly simple—no messy wax to deal with, and it was easy to reposition the toilet when needed.

      It created a tight, reliable seal, and I’ve had zero issues with leaks. I especially appreciate that it’s reusable, which adds great value if you need to reset or adjust the toilet later. This gasket saved me time, effort, and cleanup. Overall, it’s an outstanding product for anyone doing a toilet installation or repair.

      This is a GREAT product for the DIYer installing a toilet. Bees wax rings have always been sketchy in terms of consistently providing a good toilet-to-floor seal. This product is easy to use, no mess, and consistently provides an excellent seal. I have used this product on three different toilets in recent years with 100% effective results. Good to see technology finally evolving beyond bees wax!

      Over a decade ago when I needed to replace my toilet seals, my choices were wax rings and Sani-Seal (SS, henceforth). It was easy to install, but I recently came across reviews questioning SS' durability and that made me wonder what was going on with my installations. I pulled the first toilet to find that the SS appeared visually functional. Physically, however, it was saturated with fluid. The gunk on the bolts and caps spoke to how the now-oversaturated SS had begun to ooze fluid when the membrane sealing the foam had failed. Interestingly, I had installed the SS unconventionally, but I don't remember why. This upside-down orientation might have given me a few extra years of use based on where the membrane had failed. I then pulled the second toilet to find that its SS had not experienced membrane failure, even though I had installed it sixteen months before the failed one. Rather than the difference in orientation, I believe that the failure of the newer SS was due to a defect in the membrane.

      In addition to the less-than-lifetime durability, I am not a fan of the current-generation's "shortened extension". The longer sleeve in the first-generation SS was one of the two features that attracted me.

      It's awesome that in 2024 there is a wide assortment of waxless seals. This time, my goal was to find one that 1) doesn't use foam and 2) is a one-piece design. Many designs stack separate layers of mixed materials to accommodate flanges that are below the floor, which is the case for both of my toilets. Water has a way of seeping past layers, given sufficient pressure (as when plunging). Therefore, I avoided the offerings from Danco, Fluidmaster, Korky, and Reliabilt. After purchasing the Fernco FTS-3 and One-N-Done T10-OND-200-DS, I settled on the latter. If the OND had not met my expectations, I would have settled for the second-generation SS and set a reminder to check them after five years.

      It's not realistic to believe that any toilet seal would last anyone's lifetime. Why does the company continue to advertise a lifetime warranty? Maybe SS would have sent me a free replacement for the failed SS. There's not an easy way to determine the likely limited benefits of this warranty because their Contact Us feature on their website is broken.

      These work great with uneven floors in old houses. Shims help to keep the toilet from moving but if they come out this insures you wound have a messy leak.

      It leaked. But considering the circumstances of placement we are kind of screwed on returning it. It’s really no longer sanitary. I wouldn’t want to buy a used one. So live and learn. Didn’t work for us. Stick with a cheap wax ring.
