Shown below are individual petrified wood sinks and bowls available for sale. Most bowls can be drilled out to be used as a sink. Drilling adds typically 1-2 weeks. Each piece is unique and displays the grain of the fossilized wood tree that originally grew over 30 million years ago. Bulk quantities are available for commercial jobs looking to purchase more sinks or bowls than are listed on this page. The sink holes are drilled with a 2.5″ recess to accept the drain flange and the hole is 1.625″ wide.
