We get lots of requests for information on how to soundproof a room but very rarely do we get requests for information on how to soundproof a bathroom. It’s not that it can’t be done but so very few people consider the bathroom a source of invasive noise.
There are, on the other hand, plenty of people who find bathroom noise to be incredibly annoying. Imagine living in a house where one person works a day shift and another a night shift. You may come home from a long overnight shift, settle into a deep sleep, and then suddenly wake up to the sound of the rest of the house taking their morning showers and flushing the toilet. In these cases – yes – we can see how you might find bathroom soundproofing necessary.
The project shouldn’t be too tough but you have a lot of extra material (permanently installed bathtubs, showers, and cabinets) to work around. You may need to float the walls or ceilings and install some mass loaded vinyl. We’ll be honest – this project may be a bit more difficult (if for no other reason than space) and should probably be done during the process of remodeling or gutting your entire bathroom for best results.
You won’t be sorry when you’re done, though. Imagine – a full night (or day) of sleep without hearing the toilet flush!
