Again, allow me to emphasize the fact that all snakes are different (just like people). Your snake may or may not allow you to handle him/her during the shedding process (also, don't take it that simply because the snake allows you to handle it during shedding that it likes being handled. Shedding is an extremely uncomfortable time for a snake.). It is also recommended that you do not disturb the snake during this critical time since stress can cause anything from regurges to incomplete sheds.
Also, some snakes don't like baths, only two of the corns I own like water, the other one hates water. So instead of giving her a bath, I give her a coolwhip tub full of damp paper towels (just cut a hole in the side and put the lid on), and she usually curls up in there until she's ready to shed, or whenever she feels the need for more moisture.
Just give the lil guy/gal some time and moisture, he/she'll be bright and shiny when it's all over.
