Yes...and they are fantastic too.

They stock Eleminis products like shampoo, conditioner, body wash in the shower stalls. Hair dryers, razors, big fluffy towels, and lots of other great amenities. Just be sure to bring your own brush or comb...I don't recall those being supplied last time I was there.
My husband and I go to the Rainforest every evening before dinner and then enjoy leisurely showers in the locker room. And we have the split bath, but with 2 teens also getting ready...this is just much better for us...(okay better for me) lol
