I have a Kohler toilet tank in one of the bathrooms that sweats so much
that
it forms small puddles on the tile floor. . . .
I've been told that it is because the humidity is too high in my house and
that I should get a dehumidifyer. That is out of the question . . .
Have any of you any suggestions that are at little or no cost?

Two factors governs the speed with which water
vapor (from air) condenses on the tank wall (and
therefore runs off into puddles.)
1 = Humidity (percentage of water vapor in the
air. The amount of water the air can carry is
governed by air temperature.)
2 = Temperature difference between the air and
the cold wall of the toilet tank.

If dehumidification is not attempted, you could
try insulating the tank. This is done by (draining
and drying the tank and) gluing expanded poly-
styrene or something to the side walls and bottom
of the tank. This is commonly done by some
builders, using foam a quarter of an inch thick.
The effect is small but you can try this cheaply
in case it helps.
