Boating stores carry speakers made to withstand
extremes.
The stuff that marine distributors carry is garbage...
For surface mounted solutions, you can use any decent under-eave outdoor speaker like the previously mentioned Sonance Mariner & Niles OS series. Other good choices are the Polk Atrium, the Klipsch outdoor, and the Canton PlusXL Outdoor (my personal choice).
I have used traditional in-walls in showers as well (fingers crossed)... but I was happy to see Sonance release the Extreme In-Walls.
