Do I need a diverter on the tub spout and is it included in the trim? I can't tell from the picture.A. The Kohler K-T10584-4 is a single handle valve only and does not include a diverter. If you ordered the K-T10581-4 which is the matching Bancroft Tub and Shower trim, the diverter is included and is a part of the tub spout.
Is this a handle I can pair with a non diverter tub spout such as Kohler k-6854?A. The Kohler K-T10584-4 can only be paired with the K-6854 if this is the only application it is running. If you are running a showerhead as well it will not work. Please let us know if you have other questions.
