Keeney K836-22 Anti-Condensation Toilet Tank Liner Insulation Kit, Prevents Water Damage to Floors, 16-Inch x 48-Inch, White

It went in pretty much as expected. I used additional glue and Flex tape.

Easy enough to install but worthless. After 2 months the adhesive is no longer holding. The liner is lifting up at the bottom and interferes with the flapper so the toilet keeps running. I followed the installation instructions exactly and even let it sit for a couple days before filling with water to make sure the adhesive had time to set up but it didn't matter. I've used thicker foam pads before that had a tube of adhesive which worked very well but was unable to find them this time around. At least it was pretty cheap.

I read the other reviews & found using extreme glue no drip Gel Loctite one tube only. Still have 1/3 left. Glue inner by one inch & two inches in between . I did use this on a new one piece toilet in not having any issues with wetness I believe it is best with no bonding concerns. It is still best to cut each side separate as tanks are all different as mine had radius to deal with. This will give you more time to do it correctly with no mess. Yes you will have seams. I also used amazing goop clear for seams for concerns of edges from peeling in the future.

This stuff does not adhere if water can get behind it. I recommend once you install it you use silicone around the perimeter, or the window and door expanding foam. If you use this to seal all the seams and bottom it works great. (You can always trim it when it dries) This by itself isn’t much use. I had great results using expanding foam on the bottom of the tank and around the bottom edges and seams. No more condensation!

We were having significant sweating on the toilet bowl. My husband and son installed this and so far so good. It still sweats a little bit, but no where near as much! It was easy to install.

I took everything out including the water. Let it sit to dry and applied the product. Next day I came and the it has started piling off. The toilet was still sweating like nothing has been done to it. 2 days later I noticed the water was running longer and I checked and the product was blocking the stop mechanism because it was piling of even more . By day 5 I decided enough was enough , more that half of the product was not attached and was sort of floating. I decided didn’t want my bathroom and basement to flood and took it out. Waste of time , energy and money. Don’t buy it’s not worth.

Installed by a plumber into a brand new toilet in September of 2019 following all directions. In less then 6 months it started peeling off. Today after less then a year we had to remove it all because it wouldn’t stick. It was preventing the plunger part from sealing causing the water to continuously run because the back couldn’t fill. Every time you flushed you had to reach into the back of the toilet and pull the insulation piece out of the plunger seal so that it could seal and the toilet could fill. Waste of money. The only reason I gave it two stars is that it did reduce the condensation for about 6 months.

To be successful with this kit, you have to dry the inside of the tank, I used a wet/dry vac. Also I cut mine into 4 pieces, wide part of tank front & back and the narrow sides left & right. I purchased a tube of Loctite extreme glue gel from HomeDepot. I put a strip of glue every 2in from bottom to top of inside tank, one section at a time, pulled backing off insulation and press onto wall of tank. I let it sit for 45 min before refilling tank. Worked great! No condensation yet!

This is a great product. Normally, we would never buy a toilet with an unlined bowl but the only only one we could find to fit the space came unlined. This kit made it an easy fix (we installed it on a brand new toilet, so it was super simple) and three months in, we have had absolutely no condensation.

It was fairly easy to fit but due to the shape of my cistern I had to make small tucks at the corners. It has greatly reduced the condensation on the outside of the cistern.

This was basically garbage and a complete rip-off! Not only was the foam too thin to insulate anything, but it was a total bugger to install properly even in a brand new toilet! (So, conditions were nice and dry, just like they asked) After about a week, the toilet didn't seem to be flushing properly, so I lifted the tank lid to find that the whole thing had come away from the walls of the tank and was floating in there. Had to use scissors to tear it all out as it wouldn't go back down (obviously). Back where we started, minus $40+ and a whole lot of time and aggravation!

Bought this for toilet as we had a lot of condensation in our new toilet, stickiness stopped sticking. Don’t waste your money, poor quality.

Installation was a bit tricky. My tank was a little tapered at the bottom so it left some bubbles. But it's seems the work well. No condensation so far.
