Is there a fan in the bathroom with a red light?

It depends on the wire diameter of the line, and the bath bomb has a lot of power. Old lines don't necessarily fit. As for remote control, it's not necessary. You'll also have to put a remote control in the bathroom, and you'll have to find it if you want to use it. There's that effort, and that's it.

It should be a bath bomb, no problem can be used normally, because it is an infrared light.

First of all, the bathroom must be clean, otherwise it will have to be covered with a mosaic. >>>More

No, the red light is mainly emitted by colored wires, and there is no heating wire.

Bathroom exhaust fans have special ducts. You take a closer look. Or ask about the property.
