This morning when I woke up I found that I had no hot water in my
bathroom. The fixtures work fine on cold, and water continues to flow
out until you turn the dial to the middle (warm) and the water
pressure drops. When I turn the dial to hot, no water comes out at
all. The rest of the rooms in the house have hot and cold water, its
just the tub, shower and sink in the one bathroom. Any ideas of what
this could be?
Sure sounds like a frozen pipe, especially since it happened at the same time as
a sudden temperature drop. It's not all that uncommon for just one room to be
affected, especially if it is at the end of a run. Your hot water supply may run
near an outside wall at just one point.
You will just have to poke around and find the trouble spot. If you have access
from the basement, you can figure out where the pipes go up to that part of the
house, and figure out where the pipes may pass through space in an outside wall.
This often happens in Kitchens, and the solution there is often to simply open
up the cabinets beneath the sink to let the warm air from the kitchen thaw
If you find an area that you think is suspect and want to thaw it, make sure
that you leave a few related faucets open a crack so steam and pressure has
somewhere to go. Some of that pressure will be in the direction opposite the
bathroom, so you need to open more than just the bathroom valves.
I would recommend a heat gun or hair dryer rather than a torch. A torch would be
faster, but it adds more risk of bursting a pipe (bad) or unintentionally
igniting materials inside the walls (VERY BAD!)
If it starts working again when the weather warms up, you'll find out!
Seriously, it's definitely possible for one of two pipes to freeze, depending
on the exact location.
When was the last time you can remember it getting as cold where you live as
it did last night?
We broke a 100+ year low temp record here in Boston last night. And it was
over 50 F here on New Years day. Go figger. I hope the Pats fans see a great
playoff game tonight, but I'm glad I'm not gonna be in the stands.

My shower did that several years ago. All in one valve in my shower. I had
to take the bloody thing apart and replace the plastic insert that had
snapped off. My case was hot water only no cold...
Get some patience at the store before you attempt this. It can get ugly, to
the point of having to rip out the wall and replace the valve... I got lucky
and it was just a couple of hours and 4 trips to the store to get the right
