KOHLER K-97339-NA Mounting Block for Kohler Artifacts, Purist, Stillness, Margaux, Kelston and Composed Freestanding Bath Fillers 2.25 x 4.69 x 4.69 inches

Our contractor secured the mounting block to the floor floor joists before the tub arrived, but he still had to cut a hole in the ceiling below to complete the tub installation. Thats a minor inconvenience but was not unexpected during our bathroom remodel. Theres absolutely no wobble with the filler. Be sure to follow mounting instructions BEFORE you install the bath tub so the filler is positioned correctly. We had to loosen the four mounting screws and rotate the tub filler so the hand sprayer dripped in the tub and not on the floor. The mounting block provides four stainless steel slots that facilitate rotating the filler to the correct position. Be sure to not lose the locking washers if you remove a screw. I used a paper clip to fish out the washers from the mounting block collar.
