With the appearance of aged stone, our Cherub and Shell 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). It is reinforced with a fiberglass backing. Lightweight yet durable, this birdbath may be left outdoors indefinitely. Made in the USA. Please note: 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.
