Shower drain has recently started gurgling as the last water goes down. There is no pooling during the shower. Any ideas?

Man, you should worry if it wasn't gurgling, and was pooling up during a shower. That's the sign of a slow drain, but yours seems to be draining VERY well.

Hi Dbmcnair

A gurgling at the end of a fixture draining can be either the back pressure caused by a PARTIAL BLOCKAGE to the drain, or it could even be that the shower vent is clogged. I'd snake the drain as gurgling and burping drains allow sewer gases to escape into the home and that is not a good thing. You shouldn't have to snake more than 10-15 ft. maximum if you have a typical bathroom.
