The answer to 'bathtub frozen' is that a frozen bathtub is typically caused by cold temperatures and lack of insulation or heating around the bathtub pipes. Symptoms include the bathtub not draining properly, the water not getting warm, and potentially visible ice buildup. To solve this, you can try running hot water, using a space heater, or insulating the pipes, but if the issue persists, it's best to call a professional plumber to properly thaw and inspect the pipes for any damage.
Frozen bathtubs are a common problem during winter, especially in older homes or homes with poor insulation. It's important to address it quickly to prevent further damage and ensure the bathtub is functioning properly again.
