This is a beautiful tub! We bought this (68 x 31) for a whole master bath remodel and had a professional bathroom renovation company to install it. It is quite large and no sharp edges. We had to have a hole cut  in our laundry room ceiling below the bathroom to access the drain. This is a very good idea in case of leaks. Also our floor was not completely level so the adjustable feet were useful to level the tub. Even so, the bottom of the tub was covered all the way round with some gray foam (our installers came up with this solution and it is invisible if you look at the photo) and then siliconed in place so that it can’t move accidentally. Overall, a very lovely tub for a fraction of the price of much heavier and more expensive tubs. Delivery was perfect, and no damage whatsoever.
