Bathtub Drain !!link!! Freezing -
If you suspect a frozen drain, Chemical cleaners generate heat to dissolve hair and grease, but they cannot melt a solid block of ice. Worse, if the chemical sits on top of the ice, it can generate enough heat to crack the plastic PVC pipe, leading to a leak that will appear the moment the ice melts.
Pour one cup of rock salt (ice melt) directly into the drain. Follow it with a kettle of very hot (not boiling) tap water. The salt lowers the freezing point of the ice, and the hot water transfers heat. Wait 20 minutes. Repeat. bathtub drain freezing

When the wind chill drops below 20°F (-6°C), cold air seeps through foundation vents, missing insulation, or cracks in the siding. That cold air hits the cast iron or PVC pipe. Add a little bit of standing water left behind after your shower, and you have a recipe for a solid ice plug. Follow it with a kettle of very hot (not boiling) tap water
The "U" shape under your tub is the P-trap. It is designed to hold a small pool of standing water to block sewer gases from entering your home. Because water sits there permanently, it is the most vulnerable point. If the air around the trap drops below 32°F (0°C) for a sustained period, that standing water turns into a solid ice plug.
Bathtub drains are often located along exterior walls or in crawl spaces with minimal insulation. If your tub is against an outside wall, the pipes are separated from the sub-zero temperatures by only a few inches of framing and insulation—or in older homes, nothing at all.
A frozen tub drain isn't just an inconvenience—it can be a disaster. When you run water to try to melt the ice, the water has nowhere to go. It backs up into the tub.
