You can put an electric heater in there to warm it up but if the plumbing is like mine it may freeze anyway.
My plumbing runs under the floor and comes up into the bathroom in the wall. No heat in the floor or that wall. I have opened the wall and wrapped the pipes but that doesn't take into account the pipes in the floor, where the heat is but an engineer's wet dream.
