Any plumber anons in the house? Weirdest occurrence in this house. Taking precautions with cold and kept kitchen sink running overnight no issues and no issues anywhere else in the house. However, anon's family member tried to shower and no water from shower but sink in bathroom runs fine. Checked shower. Slight layer of ice in the TUB near the drain and drain is very cold with ice on the edge. This house is on a slab and the plumbing is very odd. Any suggestions? Shower faucet is slightly on and I have an oscillating heater on a plastic panel directed to wall of shower. The bathroom is centrally located and I had no idea the pipe could freeze like this.
