@mcneely I'm up in Lehigh and I've been dealing with a frozen toilet these past 3 days. Weird situation though. A small lean-to type porch was added outside the bricks with no insulation and that's where the powder room is. The sink is fine, it's just the line to the toilet plus the tank and bowl water that freeze. There's no electrical outlets out there so I'm just putting a stockpot of boiling water out there every few hours to keep things flowing.
