    Soundproofing insulation inside the wall helps. A new wall can be installed over the old wall (not touching). That may require some electrical work depending on your layout.

    The easiest way may be to blow insulation in between the studs if you have drywall. You can then patch the holes and repaint.

    My bedroom wall is also along the bathroom wall. We replaced our toilet with a new one probably about a year ago and I no longer hear the toilet flush at all. We went with a cheap one, about a hundred dollars that has the dual flush button on the top of the tank and it is amazingly quiet compared to our old one. We also put on a different seat, one of the no slam ones so that we wouldn't hear that either (we have to close the lid, one of my sons dogs likes to drink out of the toilet, Yuk!). Perhaps putting one of the newer water conserving ones would help with the noise in your bedroom, Lolly. It may end up cheaper in the long run. Hubby wanted a little more height on the toilet and the oval seat and not round, he had trouble getting up and down on the low height of the toilet we had. We had to replace the basement toilet, you could no longer get parts for it because it was that old, so we replaced both at the same time.

  • You might try using a white noise machine, and also add more rugs, curtains, and other textiles to your bedroom and the bathroom. It will help absorb noise.

    Have a few questions Is this your home? Are you staying with some one room-mates,renting a room from someone? Here's your options for your home https://www.youtube.com/watch?v=-jevPIJmABA Spray foam alone in walls does not stop noise. Renting/room-mates Definietly don't have bed on that wall put dressers there instead to help defer/block noises. Hang blankets on wall over sponges to baffle noise then dressers in front.

    I would seriously consider moving.

    Hubby plays music so have tried a lot of cheap solution. Hanging blankets on the walls help. Any material helps to absorb the sound so it doesn't bounce off the naked wall.

    I know ear plugs can be uncomfortable but they are about the cheapest solution.

    Years ago I got a white noise machine from Goodwill and it worked for years.

    Hi Lolly, hope this helps. The easiest way may be to blow insulation in between the studs if you have drywall. You can then patch the holes and repaint. You can hire someone to do this for you, it will make a big difference!


    As far as soundproofing goes, anything cheap or easy will not be effective. The gold standard (short of using concrete) would be to make a double wall by removing the drywall on one side of the bedroom-bathroom wall, then building a structurally separate wall that is not attached to the existing wall.

    There are companies who can boar holes between the studs and spray insulation into those spaces, then repair the holes so the walls look the same as before. This should provide a good sound barrier to prevent the noise from the bathroom. Over the years the price will be well worth it.

    Blown in insulation would help tremendously. In fact it would be a great idea to do the entire house at one time. Home Depot and Lowes offers this service as well as from Home service places like Thumbtack.

    Hi Lolly: Perhaps you are addressing the wrong area :) How about addressing the noisy toilet? You can buy a product that is quieter when refilling the toilet: Korky QuietFill Platinum Fill Valve 528MCM - The Home Depot I have them and put them in myself. Just be sure to turn the water off to the toilet and follow the directions on the box and Bob's your uncle! :) Hopefully this will help. You can even get one of those toilet tank cover sets to make it quieter; Amazon.com: Wissota Trader Stoneberry Home Plush 5-Piece Bath Rug Set, Black : Home & Kitchen And, maybe you can move your bed to another wall?


    Good luck

    Adding sound-absorbing materials like acoustic panels or thick curtains on the bathroom side as well. Wayfair sells sound proofing wall panels.

    Hi Lolly: Well, can you move your bed to the wall furthers from the bathroom wall? Two other things you can do:


    Get a quiet fill toilet filler: KOHLER Silent Fill High Rate Toilet Valve Kit GP1083167 - The Home Depot


    Get a roll of Quiet Walls. Not cheap, but it should work. Quiet Walls 48 in. x 10 ft. Commercial Sound Barrier Quiet Wall D310305 - The Home Depot Check the reviews.

    Ask the Lanndlord to do something? Place a not in the bathroom or speak to other users saying it is a probem for you as you can hear clearly every sound they make. They may get on your side and ask the landlord to do something too. You could possibly move the bed or move out?

  • Sometimes a wall hanging of fabric, like a quilt or heavy tapestry can muffle the sound. We had insulation blown in the wall and it does work but it was a job...

  • Hi Lolly! You can add some thick wallpapers can help to deaden noise but they won't make much difference on significant noise. If you want a fast solution to cut noise coming through a wall or ceiling, try nailing a thick blanket to help dampen the noise. Hope this helps!

    Hi Lolly, hope this helps, the one thing you can do is have white noise while you are in your room, I sleep with rainfall sound every night. If this works then you won't need to soundproof.

  • You could add some blow in insulation. That will require some holes in the walls which will need patching and painting. You could see if there's a company by you that can do retrofitted spray in expanding foam which would be even better.

    A couple of ideas would be to install a vent fan in the toilet area if there isn't one now. Another possibility has been suggested by others which is to add insulation on the walls around the toilet. You might also be able to add a white noise machine in the toilet area so people can turn it on to mask the sound. Sometimes one could flush the toilet a couple of times while using the toilet so the "flush" masks the sounds.

    Could you possibly move the bed? Put insulation board in the cavity of the wall by then creating another wall in front of existing wall.
