What's up with Shower?

I always say (and hear) "xǐzǎo" 洗澡 for "to take a shower."One time, I wanted to ask at a hotel if the room had a shower. So I asked if they had a "yùshì" 浴室. The front desk worker said, "xǐzǎo ma?" 洗澡吗. Ok, sure. So, I guess it's a noun too?If you'd be so kind as to leave a comment, I'd like to do a little poll:

1. What word(s) do you say for "a shower" (n.) and "to take a shower" (v.)?

2. Does your favorite dictionary have "xǐzǎo" 洗澡 under the English definition for "shower"?

3. What dictionary was that you just checked?

If I hear back from anyone, the results of this poll will help inform an upcoming article I'm writing.Thanking you in advance.
