It's well known that humans vividly hallucinate sounds - specifically overtones - that aren't really there; given specific sound (harmonic frequency) combinations.
It may be that how well you are able to "hear" (hallucinate) overtones is involved in this effect. Moving into the bathroom changed what I heard, and extra reflection of sound would alter overtone perception. I interpret that as (rather weak) evidence for the hypothesis.
