Purchased the smaller  cabinet to fit in our small bathroom and have cabinet expose more flooring to feel bigger.  luckily all the waterlines and drains did not need to be adjusted.  But as other have said the legs go right against the wall making the need to notch the wall trim to make the cabinet flush.  The only issue (from a laymen)  is the final connection of the base to the sink.   The one piece sink top is really nice but no obvious means to finalize the bond together.  Other then that, I smile every time I see and wonder why I didn't buy it sooner.
