Robert Kuo designs are the proclaimed ‘greatest art pieces for the bath today.’ The Zen bath is one of his pieces. The Zen bath is a hand crafted one of a kind tub. The copper bath construction is a tribute to his style. It is another great example of functional art. Robert Zuo has done many pieces for Ann Sacks. They include the coordinating Zen basin, bench and Wavelet series. You can view them at Ann Sacks.
