This flat-based, rectangular vessel features 90 corners and a platform with a pre-drilled faucet hole and overflow. The additional vitreous china coating on this model creates an even more impervious and sanitary surface than standard porcelain. With an overall measurement of 21 in. x 16-1/4 in. x 5-3/4 in., it will require a minimum-width cabinet of 21 in. Due to the design of some vessels and their open backs, faucet hardware and unfinished areas may be seen if installed directly in front of a mirrored surface.
