Dear Sheila Jeffrey: Please click on the green "more information" text underneath the photo to see the full conversation about wooden basins. Our company is not involved in interior decoration or finish, so we have no way of knowing where this sink came from. Sorry we couldn't be of more help.

This sink might be a European Dough Bowl from Ballard Designs catalog, but it looks like it is sealed really well with something.

Dough bowls, biscuit bowls can be found at flea markets and antique stores. They come in lengths over four feet or longer. And as small as eight inches.
In the south the huge extra long bowls are called Hog Bowls or BBQ TRAYS.
tin can be found for sale by people who tear down barns for salvage. Look on craigslist for reclaimed barn
