This is a really old thread, but just to add, in case someone is researching Kohler Archer: from my experience, I don't recommend it for kids. The problem is the pop-o-matic stopper mechanism, when my kids sit on it or accidentally push on it, it pops open and the tub drains.

You paid for it, they should fix it. Is this a removeable panel used to service the motor? Then it can be recessed. I'm thinking the contractor has been paid and long gone. But the tile work looks very good so I would call him and ask him if they could recess it. Question is this a real panel or just trim applied to the front of the board.

We put one in the master bath nearly 20 years ago and it still runs fine, but it seldom gets used. We have 2 hot water heaters in our house; one serves the utility room and master bath and one for elsewhere. The jacuzzi depletes the hot water heater so by the end of filling the jacuzzi I'm running cold water. We recently redid our bath and I opted to keep it since it's the only "tub" on the main floor. During the reno we put in a new tub faucet and now the water runs in so slow it takes forever to fill. Now I wish we would have taken the jacuzzi out. We could have used the space for storage or something else.
