It is very small and not suitable for a main bathroom. I would have returned it too if I knew the plumber would charge extra ($700 to install) and spend an excess amount of time/labor to install these types of toilets (easy to clean means very difficult to install). It took 2 people to install it and a third person would have been needed if we had them. It’s design-wise great from an aesthetic stand point however, but check with a plumber first before purchasing.
