Would recommend having this professionally installed unless you have a lot of experience with electrical work and some carpentry. Comes with it's own control box which for me replaced two switches(one for fan and one for light) in my 3 gang box. Had to convert my other switch(for my vanity light) to a decora style(large rectangular cutout) and install a white plastic decora cover with a blank insert(available at HD) on the unused gang. Old fan used 4 wires, and this fan only uses 3 wires, so I clipped/taped the unused wire and moved it to an out of the way location. Would have a multimeter or voltage probe/continutity checker on hand to make wires are not energized before you touch them, and you find the correct wires. Requires 9.4x9.4 square opening in ceiling, and round grill covers it up nicely. Controller has rocker power switch and four membrane buttons for night light, light, fan, and music. Paired right up with cell and speaker had decent sound quality/volume. Light is plenty bright, and blue night light gives room a cool ambiance.
