How do you know? It works like any other sink so i doubt it's useless or uncomfortable(?!?!) and as for complicated to build it's a poured concrete mold how could it get any easier? i will give you that it takes up what appears to be a lot of room although 2ft across isn't really that bad as for the cleaning bit i don't see how hard it could be wipe down once a week with a sponge. I mean it's not like it's a kitchen sink that you are trying to clean veggies in it is very obviously a bathroom sink
