I am building a stool that will be placed in our stall shower. Rather than start right in with expensive teak, I am building a prototype out of some scrap cherry. I intend to place it in the shower to see how it fits the needs of the family. My thought is to finish it with three coats of poly, but I wonder if several coats of tung oil would be better. Any thoughts about the best finish? Thanks.

I would strongly recommend you avoid any type of film finish for your prototype or you final project. Bare feet, water and a smooth film finish is very dangerous.
Let me say that teak is an excellent choice for your application. When you build it, do not use a film finish like varnish or poly varnish. Both are exceptionally slipper when wet and walked on with bare feet. Teak is used on boat decks because it is naturally non-skid. If you want to use a finish, use a marine teak oil but no finish is a perfectly good solution with teak.
Best choice is to use the teak, and leave it "au naturel".
You could also use ipe, if you don't want the expense of the teak.

Don't use a finish for your prototype. Once you decide on you final design, use teak or one of the very dense stable hardwoods like tigerwood or something light like cedar or redwood. White oak may be an option as well.
Who knows, maybe the cherry prototype will be what you want.
Don't use oil. Spar varnish or Sikens marine. Any finish will likely have to be renewed regularly.

I agree with Howie and Dave, I would not use a film finish. If you have ever been inside a sauna (wet or dry) they use unfinished teak or cedar and that is it. There is no finish on my teak boat deck, just power washed a couple times a year.
Without reading the other posts. White Oak...
EDIT: BUT OAK splinters!

Thanks to you all for the good advice. I finished the cherry prototype with a single coat of tung oil. I also sealed the end grain on the bottom of the legs with diluted yellow glue. It came out fine and if I can figure out how, I will attach a photo. If and when I build the version in teak, I will not be putting any finish on it.
