The Stone range from Chartley includes a range of top quality, highly polished chrome circular shaped taps called Onyx. One tap, in particular, is flying high due its combination of style, quality and price. The Onyx floor mounted bath shower mixer, retailing to consumers at £765.00, is enjoying a real surge in sales due to the popularity of freestanding baths.  With competitive products running into the thousands of pounds mark, the Onyx version seems to have hit just the right spot with customers.
