My greenhouse is being manufactured! My DH is building me a potting bench with a sink. He thinks I should put a big utility sink in, but I want a smaller one to give me a little more work space on the potting bench, and a little more room under the sink so I can put an r/o system under the sink.. Do you think a sink with an interior dimension of 18" x 12" and 8 inches deep will be big enough? The other one I'm looking at is interior 20 x 15 and 9.5 deep. The smaller one has the drain in a back corner. the bigger one's drain is centered

Thanks for any input! Clara
