Most guys use a scuttle, or they float a bowl in a sink of hot tap water. Just park the brush and it stays nice and warm.

I say should be because it has, on its way to me in Topeka, Kansas, gone from Virginia to New Jersey (away, to the NE), then to Arizona (past, and then away to the SW), then to Kansas City (past, and then due East) and theoretically should now come to Topeka. Unless they send it to Denver, or Guam, or something. The ways of the Post Office are mysterious indeed. I believe the colloquial term is "Dude, ***?"
I have both a Moss Scuttle and a Dirty Bird Scuttle. I love them. I get nice warm lather. Now I need to learn how to build a great lather in the scuttles. That is my weak point, I seem to be generating thin lathers. Maybe it is my lather-building inexperience? I'm only just learning that there are excellent shaving creams in the world. Maybe I need to add hotter water to the scuttles, to encourage a thicker lather? Maybe it is my Washington, D.C. metro area water chemistry? That is to say, it originates directly from the Washington Suburban Sewer Commission and a few million miles of buried water pipes. Most of which are ready to break.
I place my lather bowl on a coffee cup warmer, which you can buy at Wal-Mart for less than $10.00.

Although I have no personal experience with them, I have read here that sometimes using a scuttle or shaving with very hot water will actually have an adverse effect on getting a good lather up. Something about the lather getting too hot and collapsing... As always, YMMV, but there it is.
