Bathroom sink and shower drains froze in new bathroom addition. Plumber able to defrost sink but shower still frozen for 5 days. Pipes were insulated by contractor. What can I do to unclog shower drain and is there anything I can do to make sure this doesn't happen again. This bathroom is over an unheated crawlspace on the side of our house.
