Adhesive to use in a toilet tank

Hello .. I want to insulate a toilet tank. I cut blue foam (camping pad) to fit the tank, it fits nice. I need to glue it to the tank itself but am uncertain as to what kind of adhesive I should use. The tank is bone dry, has never been used yet ..I bought it by mistake but can't return for an insulated one. Does anyone know what kind of adhesive I can use for this project. Thank you.

Why do you see the need in insulating the toilet tank? How hot do you keep your room temperature?

Unless the insulation is 100% sealed and the water cannot touch the tank.... it will still sweat.
I don't think you can seal the foam to the tank to even make it effective.

I have always purchased insulated toilets. I thought that if the toilet didn't have insulation, it would sweat due to the cold well water. I don't like the idea of even risking it ... I don't particularly like sweaty tanks and I put new floors in and don't want to risk messing them up .. I hope to sell in the Spring. So ... seen a video on Youtube , the UK fellow used a yoga mat and 785 silicone sealant .. the job looked pretty good. I wasn't sure what the best product would be here in the US (WI right now) to adhere closed cell foam to the toilet. I know they sell the kits to insulate the tanks but this fellows job looked better to me and I had an extra mat so .... decided to try it out.

You could use a tempering (mixing valve) to warm the water entering the bowl. Example: https://www.amazon.com/Industries-10.../dp/B000BQMKCY

Foam board adhesive would fasten the insulating mat but is not recommended for constant immersion.
I would try the silicone and see how it goes.

I have encountered only a few sweating toilet tanks over the years. Yes, well water is cold, but these ladies were keeping their houses at 80 degrees in the winter. I couldn't breathe, and naturally the tanks sweated. You haven't stated how hot you keep your house. It will have a direct bearing on the sweating.

It sounds like sweating toilet tanks must be a regional thing.
Even in our cold climate the sweating of non-insulated toilet tanks is very common due to high humidity and cold municipal water.

I have one of those kits around here somewhere; unused because the toilete went into production before the kit was used and has never been dried out since.

Will a hardware store tell you what kind of adhesive is included in the kit ?

I have resorted in the past to tying a short strip of cloth around the incoming water line and created a drip strip to direct the water into a small container. That works fine if you have multiple baths and the fixture isn't used frequently.

If I can set my eyes on that "kit" I'll report back on what kind of glue was included.

Sure appreciate all the feedback. I might try the Loctite or Gorilla Silicone from Menards then and see how it goes unless someone comes back with something better. I will also try find out what they use in them kits, good idea. I live in Canada and heat with wood so my house gets cool at night and can be warm at times .. depending on how many sticks I throw in. These toilets are in a house in Wisconsin and I stay here when I work on the house. I keep it less than 70F ... maybe I would never have a problem but it sounds like a lot of people have problems with sweaty tanks (online forums) ... figured I would insulate before I fill them with water, don't want to take a chance ... would like to leave the new owners with Non sweaty tanks. Anyhow, thanks a lot for help...

Smile Tube of Loctite & my old camping mat ...

I lined out the toilets with my camping mat. Found a tube of Loctite at Menards, good for aquariums. Adhered, let it dry, topped off the top with some caulk and it has been working fine. Been months now. Just need iron remover now..Name:  Toilet.jpg
