Our not-your-usual birdbath is cast from a mixture of sand and stone that has been reinforced with fiberglass. The surface is then sandblasted and treated to create an aged look. Variations in color will occur. Made in the USA, it may be left outdoors indefinitely. While our statuary 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.
