My bathroom is shaped like a barn...it is 12x9. The 12 foot walls go up 6 ft on one side then slope at an appropriate 45 until it meets the 4 ft flat section of ceiling, the other wall starts this at just over 5 1/3 feet, until it meets the other side of the ceiling. The previous owner has a short medicine cabinet (on the shorter side)...at 5`3 I have to bend to look in it...they did this to accommodate a light bar. I am taking it out and putting a taller mirror in the place of it. The ceiling now has a ceiling fan w/ a light (ceiling is 10 ft). Can I mount a track light on a sloped wall, or would it be better to just replace the fan with a light? My house is an 1890 Folk Victorian.
