I would use "spec grade" wherever you find yourself plugging and unplugging appliances frequently.
I just went back and reread your post and originally read "bathroom" where you really said "bedroom." So my comment about the GFCI does not apply, and my other comment about frequent usage may not either.
If your bathroom does not have a GFCI receptacle, you likely have a GFCI breaker feeding that circuit in your breaker panel. '88 should be more than new enough that that was a requirement back then.
