I originally ordered the k5718 h2 and was discontinued by the time by builder went to order it and this is a disappointing replacement. First the specs indicate is it basically the same model, which misled me into letting builder get it. But it’s not, there not control panel to manage heat and massage flow. Both tubs had the drain in middle and on this model it’s a push down to close type of drain, so has u move around in tub, the drain pops open,,,very very poor design. Very sorry for this purchase and I had higher expectations from kohler.
