I get asked all the time where can a person find old doors, sinks, etc. for home restoration projects. My brother Kerras is a multi-talented individual in that he's a folk artist; furniture builder and collector of antiques, etc.!
At any given time he has about 300 old doors for sale; cast iron sinks and tubs along with alot of antiques. Be sure to visit his website: www.birchgate.ca/kerras; http://www.birchgate.ca/kerras/antiques.html
Below is a project where one of his cast iron sinks and doors were incorporated into a house renovation.
