Wet (condensation) Toilet Tank.

Wet humid air in any room will condense on a colder surface. The outside of a toilet tank is a perfect condenser especially when it is cooled by frequently refilling of the tank. If the toilet is not used frequently, it could have a leak causing it to constantly refill and keeping the water cold. The solution in this case may be to fix the leak. Then infrequent use will allow the water and tank to closely match room temperature and the condensation will be eliminated or at least be signifcantly reduced.

If the toilet is not leaking and is just cold from use, the solution may be to dry the air in the room. A power vent may be required to remove the humid air. If a humidifer is being used that may need adjustment to reduce the bathroom humidity.

It is also possible to insulate the tank using an internal liner. These kits require the tank be totally drained and dry and then gluing a foam liner to the inside.

Another solution is to use a toilet tank cover although this may not fit with the decor in your bathroom. The cover simply provides a barrier between the humid air and the cold tank. The degree of effectiveness will vary with the thickness or composition of the cover and how much of the tank is covered. if only the sides and top are covered moist air will still condense on the bottom. The bottom can be treated by drying on the outside and gluing on a piece of foam cut to size.
