I agree with the previous review. Just installed last weekend and, as a construction industry professional, I was disappointed by the following: 1. Can't get your hands or any type of tool adequately in to tighten toilet seat bolts. 2. If they ever loosen, you need to unfasten and remove toilet to tighten 3. Bidet seat hidden cord hole did not align with electrical or water supply of compatible Kohler bidet seat Had to run electrical and water outside of toilet. I would have chosen another toilet had I known that the cords would be exposed anyway. 4. When setting toilet, you can't see when it is properly aligned and set into trapway. Pro: Installation of toilet trapway and hidden trapway is a nice feature. If not using bidet seat, then this is a nice modern compact toilet.

This did not fit the compatible bidet seat well. The cord hiding doesn't work with the mounting bracket. Also the toilet was exceptionally hard to install and was our first kohler product that we did not like. The mounting bolts are almost impossible to secure due to the design for any toilet seat much less a bidet seat.
