Find the Source of the Noise

Before you get started, you need to start identifying where the noise comes from. That way, you can do bathroom soundproofing BETTER and MORE effectively.

In today’s guide, we will be talking about FIVE potential sources of noise inside your bathroom.

This includes the following:

  • Bathroom Door
  • Floor
  • Toilet Bowls
  • Walls
  • Windows

If you’ve identified any of those areas as the source of the noise in your bathroom, keep on reading, and we’ll help you get rid of them.

How to Soundproof a Bathroom Door

Most of the time, the noise comes from and through your door.

This problem is mainly because most doors are made of thin and hollow materials, which don’t isolate sound really well.

Luckily, there are several steps you can do to make sure your bathroom door won’t be the source of any noise.

1. Use a Thicker Door

The source of your problems will go away if you REPLACE your hollow and flimsy door with something thick and durable.

How do you know if your door is hollow in the first place?

  1. Start by knocking on your door. What does it sound like?
  2. Make sure it doesn’t sound hollow or make an echo sound.
  3. If it does, then it means your current bathroom door doesn’t isolate sound well.

What you can do to soundproof the bathroom is to replace your hollow door with something thicker and durable.

It might cost a little more than a light door, but later on, you’ll be happier with the results, especially with how well it can soundproof a bathroom instantly.

2. Use a Dampening Door Seal

If you’re looking for a CHEAP and EASY FIX, we suggest using a dampening door seal/weather-stripping adhesives to soundproof a bathroom.

Here’s how to install weather-stripping material:

  1. Start by measuring your bathroom door, and take note of its width and height as accurately as you can.
  2. Use the dimensions you took note of for cutting your weather-stripping material into their right sizes.
  3. Finally, cut the weather-stripping material, cover the gaps from the inside, and you’re done!

You’ve soundproofed your door in a matter of minutes!

It’s easy to do, self-adhesive weather-stripping is accessible, and you’ve reduced the noise coming from your bathroom.

3. Use a Door Draft Stopper

If you notice, your door has a small gap between it and the floor.

This gap allows the door to open and close smoothly without rubbing against or scratching the floor.

However, this small gap is also the reason why sound escapes from your bathroom door.

  • You can quickly resolve this problem by using a door draft stopper or door sweep. This is also another way to add mass.
  • It fills the gap in between the bottom of the door and the floor, while still making it easy for you to open and close them.
  • All you’ll have to do is install the stopper or the door sweep at the bottom of the door frame, or any room door frame even, and you’ll observe significant improvements in terms of noise reduction. Transform your door in an instant!

It’s pretty easy to purchase a door sweep. This is a QUICK, CHEAP, EASY, and effective way to soundproof the bathroom!

Soundproof Your Bathroom Floors

If you don’t want the noise from your bathroom reaching other areas of the house, working on soundproofing your bathroom floor is effective.

It’s an EASY and EFFICIENT means of soundproofing!

1. Use Bathroom Rugs/Mats

Using rugs is a QUICK and EASY FIX that won’t cost you a fortune.

Before you start buying mats to use, we HIGHLY recommend that you use rugs made explicitly for bathrooms and nothing else.

A rubber mat might be best for sound-deadening impact noise, but it might not be the best as a bathroom fixture.

Bathroom rugs and mats don’t just make great designs for your bathroom. They also serve the functional purpose of soundproofing your floor.

Putting bathroom rugs and mats in your bathroom will ABSORB impact noise, sounds, and echoes immediately!

2. Replace Bathroom Tiles

The thing you need to watch out for when it comes to your bathroom tiles is whether it’s hollow inside or if there are a lot of existing cracks.

  • Similar to how you determine if your bathroom door is hollow, you also have to knock on your bathroom tiles. Does it make a hollow sound?
  • Another way to check if your bathroom tiles have a lot of cracks is to step on them. Can you hear tiles cracking under your feet?

Sometimes, the cracks won’t be as easily visible, which is why adding some pressure with your foot can help you identify if there are any cracks.

If you answered yes to both questions above, it’s time to replace your bathroom tiles.

You don’t necessarily have to replace all of them, considering how difficult and expensive it could get.

What you do need to replace, however, are those you’ve identified are hollow inside or have cracks beyond repair.

Tiles that are starting to crack might also need a replacement; however, these won’t create as much impact noise as the cracks that are beyond repair.

You’ll find that soundproofing your bathroom floors are especially important in the long run if you want to reduce the noise inside your bathroom.

Soundproof Your Toilet Bowls

Your toilet bowls often make A LOT of weird and strange noises, especially if you’ve been using the same toilet bowl for years.

Here are EASY WAYS for you to soundproof your toilet:

1. Use a Toilet Cover

Toilet covers aren’t just there for the aesthetics because you can use them to soundproof your toilet bowls!

You know very well how annoying and startling it is to hear the toilet seat cover banging against the tank or toilet seat.

Sometimes, it makes you want to remove the cover if it weren’t for the fact that it’s unsanitary.

  • A remedy you can do is to use toilet seat covers or silicone pads.
  • If you want to take this a step further, add a seat cover to your toilet top. A cotton-type toilet cover should do the trick.

It can reduce the noise every time the cover accidentally falls, and it won’t leave you startled.

Luckily, there’s a ton of toilet seat covers and silicone pads to choose from. More importantly, they’re very AFFORDABLE and easy to find.

2. Fix Your Flush

Apart from your bathroom floor and door, the NEXT IMPORTANT THING you need to consider when you soundproof the bathroom is your toilet flush.

It produces a lot of strange and loud noise each time you use it. You might have already familiarized yourself with the sound of your toilet flush draining and refilling water inside the tank.

Luckily, there are some adhesives you can use to soundproof your flush in no time.

  1. Start by removing your toilet tank flush cap and drain it of its contents.
  2. Once it’s completely drained and dry, apply adhesive on the tanks rims and lid.

Once you’ve accomplished these steps, you’ll start noticing that the adhesive blocked all the noise coming from inside the tank.

HOWEVER, if nothing works, it might be best to install a new toilet. Check out our recommendations for the Quietest Flush Toilets.

3. Fix Your Pipes

Your bathroom pipe can make a lot of noise, especially as these pipes start to become older with time.

Even without flushing anything, you’ll often notice your pipes making noises of its own.

If you’re encountering this kind of problem, you should soundproof the bathroom pipes.

You can choose between filling the pipes or wrapping them with an effective sound absorption or soundproofing material. We recommend using a mass loaded vinyl or a foam pipe wrap.

Mass loaded vinyl is mostly used by soundproofing professionals. It should be effective to lessen all the bathroom noises.

Ideally, it’s better to have a professional help you fix your pipes. Moreover, it’s better to soundproof your pipes during the construction stage of your house instead of doing it later on.

But what should you do if nothing works…?

Usually, the sound you hear from your toilet can mean:

  • A leak in the fixture
  • Toilet tank problem
  • High water pressure, which causes the pipes to reverberate.

These are all signs of an old toilet that may require heavy repair and maintenance. In most cases, there’s a gurgling noise from the toilet because of a draining washer.

Soundproof Your Bathroom Walls

If you’ve already soundproof your doors and you still notice some noise coming from your bathroom, then perhaps it’s time CHECK YOUR WALLS for any cracks.

Here are some tips on how to soundproof bathroom walls.

1. Add Drywall

If you already have drywall installed on your bathroom wall, that’s great.

However, make sure it’s thick enough to insulate noise.

Drywalls are great at dampening noise that passes through, and it’s beneficial to the process of soundproofing your bathroom.

  • Look for drywall with MORE THAN 5/8 inch thickness or better yet, go for soundproof drywall.
  • You can add another layer of soundproofing material like a mass loaded vinyl!

The only drawback is you’ll need a professional’s help, meaning you’ll also spend a little more.

Nevertheless, the final product is something you won’t regret.

2. Install Acoustic Foam

Soundproof Pads

If you don’t want to break down your current bathroom walls, you can use acoustic foam instead.

It’s EASY to install and A LOT CHEAPER than adding drywall. You can even DIY this solution.

It’s waterproof, so you won’t have to worry about it getting wet after installation.

Acoustic foam panels designed for music rooms are EXCELLENT at insulating noises and sound deadening, making it a superb way to soundproof the bathroom walls effectively.

They can absorb bathroom noises that bounce off your walls, and lessens the echoing sounds.

These are also great to dampen exhaust fan noises inside the bathroom. But we do recommend getting quieter bathroom exhaust fans for better results.

3. Seal Cracks

If you start noticing cracks beginning to get larger in your bathroom, it’s probably because of the moisture and water buildup in your bathroom.

When this is present in your bathroom, it’s normal for many walls to crack.

  • Check your wall for any visible cracks and apply a joint compound to seal it. It’s pretty easy and cheap to do, a perfect DIY project.
  • Apply one layer of the joint compound on any cracks in your bathroom. Give it a day to dry, and apply a second layer to seal it.
  • You can go the extra mile of sanding the second layer, leaving you with a smooth wall. You’ll barely notice the job you did!

As an alternative, you can use wallpaper or paint to cover up the areas you’ve worked on. This solution is both useful and functional!

Soundproof Your Windows

If you have windows in your bathroom, it’s highly likely that noise passes through them.

Even if your windows don’t face your room, the sound waves still echo through and travel inside your home.

Luckily, you can quickly get rid of this problem.

1. Hang Curtains

Hanging thick acoustic curtains on your bathroom helps isolate the bathroom noise inside. It can prevent sound waves and echoes from passing through it.

Make sure to choose thick and heavy curtains, because they’re more effective at insulating noise than curtains made of thin materials.

The goal here is to add mass.

Don’t worry because hanging curtains is simple, and it’s a project you can do by yourself.

  • All you’ll have to do is take measurements of your window and find a curtain appropriate for that size.
  • You can install the brackets and curtains itself, or have a professional do the job for you.

But at the end of the day, you’ll have soundproof windows, without spending too much time and money.

2. Hang Blankets

As an alternative, you can use thick soundproofing blankets to add mass and insulate your bathroom window. It’s easy to install and cost-effective.

Just like what you did with the curtains, take measurements of your window and find a thick blanket that insulates sound very well.

The price of blankets can vary depending on the type of material and its thickness.

We highly recommend using acoustic sound or moving blankets, because they’ve already been proven to be effective at insulating noise.

Final Notes

There are different ways to soundproofing your bathroom, depending on your concern and how much you’re willing to spend.

You can take the expensive route of replacing your door, wall, and even your flooring to get the job done. Or you can take the affordable course of using curtains and blankets.

Whatever the case, we suggest that you go to the primary source of the noise and remedy it immediately.

If you think it’s really just your electric toothbrush, here are some ways to soundproof it!
