So your ok with water sitting from sweating. That wouldn't happen on my jobs. I would at least install a mixing valve and sort that issue out so that there were no puddles of water. Had to do it in England on a lot of bathrooms because of the high humidity and no AC on Homes. Its not hard to do and solves the issue for good.hdavis said:You just got through saying tight to the wall wasn't required. In other words, your way isn't the only way. Sweating is pretty much accepted here - there isn't usually a customer driven requirement. For the one case where the person carpeted their bath, it had to be insulated.
As for cistern vs tank, Kohler makes tanks, except for peculiar ones like their wall mount lavatory cisterns.
Never had to do it over here but as I said before I'm sure it still happens on some places.
Also just because kohler call it a tank that don't mean that's its name. Did they invent the cistern then decide to change the name? No so its still called by its original name right here in my world.
