What temperature is water at room temperature?

It's room temperature, of course.

A better question is "What, exactly, IS room temperature, anyway?"

Most chemists (I have no idea about other disciplines) consider "room temperature" to be 298.15 K, which I personally find a little on the warm side of comfortable, but is a reasonable value for a standard, especially considering that it's easier to control the temperature precisely by warming something up a little than it is to do so by cooling it down a little.
