OVERFLOW OPTION The products in the Sultan Collection have not been originally designed with an overflow hole. The purchaser has the option, however, to have an overflow hole placed in the bathtub or basin. There is no additional fee for this modification. Prior to production, the purchaser selects the plumbing that will be used in the final installation of the bathtub or basin.  That particular plumbing will be custom fit to the overflow hole and drain hole of the bathtub or basin at the factory. WAXING OPTION The Sultan Bath bronze finish is a natural finish that does not have any type of coating on the surface of the bronze. We use a different mineral in each polishing stage and the combination of the minerals that we have strategically chosen, gives our bathtubs and basins a natural seal and protection. To give the products in our bath and basin collections added protection, the option to have the bronze surface waxed is available at the factory at no extra charge. The wax coating is effective with daily use as it will allow the original finish of the bronze to last longer, thereby decreasing the amount of cleaning and care required for the bronze.      © Sultan Bath Inc., 2007.
