There is wood panneling in my bathroom on a cabinet and bath. I can't tell if the old paint is eggshell or gloss?

Obv if its gloss i need to sand it before painting. So how can I tell for sure?

You could take a proactive approach and sand it in any case. This will lead to better paint adhesion which is a good thing. It is also a great idea to wash previously painted surfaces with a strong solution of TSP (tri sodium phosphate). Make sure to use good rubber gloves and hot water - for your protection and best results. The TSP wash does a fantastic jub of getting any gunk off the walls that can interfere with a good paint job. Especially in a bathroom there is always the possibility with soap film and over spray from foam cleaners on the walls and panelling. A strong TSP wash can also remove some of the gloss from a previously painted surface for some types of paint.
