Question:
After the big freeze, all the faucets in my home water comes out of except for the bathtub why would that be?
Answer:
You may have a piece of frozen debris clogging your shower valve. You will need to shut off the water to the house and remove the cartridge/stem from the valve and have someone turn on the water for a few seconds to flush the debris out of the valve. Check the valve for other debris which may have clogged it and re-install cartridge. Turn water back on.
