I saw this black dial knob in bathroom of multiple hotel rooms. It is numbered from 0-10.
Any idea what is the use of it?
It seems not a timer. It didn't tick back. Changing it didn't -apparently- change anything.

3@NateEldredge Maybe OP could add some info, such as where he is, and whether there is a heat lamp in the ceiling.– GiorgioCommented Nov 19, 2016 at 15:32

3It's just volume for background music, which was popular for awhile but usually just disconnected these days. Ask the staff!– FattieCommented Nov 19, 2016 at 17:23

6If it’s defunct, you have a great oppertunity to add your own label as a gag. Say, “shower pH”.– JDługoszCommented Nov 20, 2016 at 5:29

Usually this controls the volume of an auxiliary speaker placed in the bathroom ceiling, connected to the room’s television. Presumably a number of people continue to listen to their television programmes as they go about their bathroom activities, although the utility of this innovation is rather lost on me.
It appears to do nothing if the television is not on.
The speaker may no longer be connected to anything if the television has been replaced since the hotel was last renovated.

3It's possible to receive radio broadcasts as well as television on many TV sets. It isn't unusual to listen to the radio in the bathroom.– bdslCommented Nov 20, 2016 at 14:06

2It certainly beats most of the alternative sound sources in the bathroom. Commented Nov 20, 2016 at 16:07
