see if you can remove the handle and rotate the stem 180 degrees then reinstall the handle.

handle removed..but stem can not be rotated 180 degrees because the allingment pins on the bottom of the stem are offset from center. Additionally two of the flow holes are round and the other is elongated.

What now???? THX

On some brands you need to remove the cartridge and rotate it 180 and reinstall.

Don't know of Kohler is like that are not.

But go to Kohler's website and go to customer support and check for FAQ's.

If that does not help them contact customer support.

not to rotate the whole cartridge,just the part that the handle goes on.leave the cartridge in remove the handle rotate the stem only.then put the handle back on.

let me know if that don't work.

another option would be to crisscross the supply hoses.

Hot Cold problem fixed. THX MUCH!!! BUT it still has to be up to be off and down to be on???

then i can look it up in that book.instead of taking quesses.

came with house, how can I find model?

looks like its a K-15175

i'm thinking whoever put the faucet on had it facing the wrong way by mistake then just reversed the handle.see if it operates correctly if you remove the handle and face it the opposite way.maybe
