I was searching the net about a convenient way to make a hot lather. Found a lot of ideas. First there was leaving the bowl in hot water. But if you don't have a big sink it's in the way. Then there was the ceramic scuttle. Which is great if you use a soap block. Found a web site that suggested taking a double lined stainless bowl, and drilling holes in the top. Then filling with hot water, and don't use boiling water. With boiling water it's makes the lather soupy. We'll I found a bowl from Amazon for $19. This system works amazing, and keeps lather not just warm but hot. Plus the bowl is stainless so it's not going to rust. Just hope this helps a little bit. Picture of the bowl.
