With the appearance of aged stone, our Charleston Birdbath is crafted from a mixture of sand and stones cast into a surface using terrazzo-like techniques. The surface is then sandblasted and chemically treated (variations in color will occur). Please note: While our birdbath is made to withstand winter temperatures, water freezing in an undrained basin can still cause damage. We recommend that any birdbath be drained and covered before wintry weather strikes. Please note: Each item is made to order. The artisan workshop does not maintain inventory and is the last facility in the USA making fiberglass garden ornaments and containers. Your order keeps jobs in the USA, but we estimate fulfillment will take up to four weeks, and sometimes longer. Hence, it is not recommended that you order if you require delivery in less time. We are unable to expedite these products, even under special circumstances.
