How cold is it where you live?

I highly suggest you crank your heat up a whole lot higher, and open a few faucets around your trailer, and hope its enough to keep your pipes from freezing further. You either pay a plumber, or pay higher heating costs.

Changing fixtures will do no good. Heating tape and insulation, and a few well placed space heaters, would have been a better investment.

Hopefully you have skirting around your home and that it is in good repair. If not I suggest that do that and seal as tightly as possible. Suggest that you place a small electric space heater under the trailer in the area of the bathroom to thaw pipes.

Hopefully winter will be over soon.
