DO NOT BUY THESE! Worst quality product. The seat cover keeps moving all the the time so it is doesn't aligned with the toilet. It chips easily. Don't even think about installing bidet after the toilet is installed as their is no way to reach to the tank inlet once the toilet is installed. My plumber charged me twice the amount to install these because it was not easy to tighten the base screws. Also, please check the clearance from the wall and where your water connection pipe on the floor as these toilet requires quite a bit of clearance.
