Soundbar for a 23" tv in a bathrrom

I need help finding a soundbar for my Vizio 23" tv that I have mounted in my bathroom. There is not a lot of need for superior quality sound, but I need something that will produce better sound than just tv speakers. Mostly news in the morning and sometimes Pandora during my after work shower. I have a limited amount of wall space to mount it. 21 3/4" is what I have to work with.

Thanks,

Rick

only 2 i can find at 20" are these, never used either so can't recommend one over the other.
