ideas for adding a sink to wet bath

We just bought a new 2417 classic with wet bath. Wondering if anyone has come up with a DIY small basin/sink that can be installed in the wet bath? We figure we can use the water hose from the shower to fill a basin for a daily sponge bath and we don't need a drain. Any ideas?

There are (or least used to be) fold-up stainless steel sinks. They were used in sleeper compartments of railroad passenger cars (hence the name "Pullman sink") and also on small yachts. In this case, Google is probably your best friend. Try the phrase "Pullman sink".
