Method#1: Soundproof the Source of the Noise

Work on the Toilet Cover 

Before thinking of any soundproofing technique, it’s necessary first to deal with the source of the noise. 

Toilets make a lot of noise in the bathroom. The noise comes from the seat cover crushing against the flush tank and toilet seat.

The noise can be too much if you have many people or children in your home. The only thing you can do to control the noise is to tell them to be gentle. But whether you tell them or not, they will forget and return to their old ways. 

Fix adhesive silicone pads on the toilet. Use one pad on the toilet cover. Place the pad exactly where the cover touches the flush tank. This will reduce the noise produced by the cover when you bang it over the flash tank. 

Use another pad on the inside part of the toilet seat cover. Fix it exactly where the cover touches the seat. This trick will reduce the noise produced when covering the toilet cover. Attach the other pads between the toilet and the seat. 

The pads will reduce all sounds produced by the toilet cover as your housemates open and closes the toilet.

Soundproof the Flush

Soundproofing the toilet flush is quite impossible, but there are a couple of things you can do to reduce the noise coming from your toilet. 


This is a common question that “how to reduce the flush noise?” 

To reduce the flush noise, use adhesives. Follow the following procedure to soundproof your toilet flush. 

  • Start first by removing the tank flush cap. 
  • Drain the tank empty. 
  • Wait until the tank dries completely 
  • After the tank walls are dry, place the adhesive on the tank rims. Put another adhesive on the cap too. 
  • Close your tank. 

The seal will block all the noise coming from inside the tank. Alternatively, you can cover the tank completely with acoustic foam panels. The foams are readily available on Amazon. 

Fill Empty Spaces in the House 

Empty spaces in the bathroom will amplify sound from the toilet and running water. Sound bounces off the empty spaces. As a result, loud echoes travel to the adjacent rooms. 

To reduce sound echoes, fill your bathroom cabinets with sound-absorbing materials. Hang fluffy towels over the storage units or on the shelf. These materials will soften the noise in the bathroom before it produces echoes. 

Make all efforts to minimize the chances of sound echoes in your room. 

Soundproof the Bathroom Pipes 

Bathroom pipes some times makes a rattling noise.  The noise might be too loud when flushing the toilet or when taps are opened. The pipes may make noise even when no one is using the bathroom. If this is the case, soundproof the bathroom pipes. 

Pipe soundproofing can be done in two major ways. You can fill the pipe cavities or wrap them with sound absorption materials. Use both sound absorption and blocking materials to eliminate the rattling sound from your bathroom. 

It’s recommended to soundproof pipes during construction.  But if this was not done during construction, you can still soundproof them now. 

Method#2: Soundproofing Bathroom Door 

In most cases, 90%, it’s the bathroom door which is the cause of all your noise problems so you need to soundproof the door. Most of the interior doors you’ll find in most houses today are hollow on the inside, or made of cardboard pieces which make them poor in sound isolation. 

These doors often have large gaps and as we all know sound travels through air and structures and so these gaps make it easy for sound to travel from the toilet to the TV room or living room. 

So how can you make the toilet door soundproof? Below are some of the DIY methods I found helpful. 

Use A Sound Dampening Door Seal 

I found this method as the cheapest but also an effective method to soundproof your bathroom door. I bought some Soundproof Weather Stripping Door Kit. (Click here to see it for yourself).

Door Seal

Unlike other weather strips I’ve used before, it’s high quality and available at a friendlier price. 

Now that you’ve purchased the seal waiting for it to arrive tomorrow-let me give the step you’ll need to undertake to get the job done right. 


  • Accurately take the measurements (both height and width) of the bathroom door. 
  • Cut the weather-stripping to size using a handsaw. 
  • Now place the soundproof weather strips to cover the gaps in your bathroom door 
  • You can cover the gaps either from the inside or from the outside the bathroom door but I would recommend the inside. Sealing from the outside would make it look ugly- my opinion though. 

This method will dramatically reduce noises coming from your bathroom or toilet and its most inexpensive method in my list of most effective methods to soundproof a bathroom. But if you don’t like it, there are other more expensive options you can use. Let look at them below. 

Try A Sound Dampening Blanket 


Sound isolation blankets are efficient in sound insulating bathroom noise. I borrowed this idea from one of my old college friends- and tried it.


Sound isolation blankets are not the most attractive method to sound dampen your toilet door. I swear it’ll make your bathroom door look ugly but you can try it if you’ve got no other options left to try out.

I ordered Audimute Sound Damping Blanket from Amazon (check it out and see if it’s appealing or not). Installing it is simpler than the above method. You’ll only need to cover the door with it and you’re good to go. 

Get a Door Sweep 

In most cases, a door sweep is a mat that’s made of sound-absorbing constituents and is positioned at the bottom of the door.  This assists in sealing the gap at the bottom of the door once it’s closed. 

You can soundproof your bathroom door in those ways. However, you may want to use some or all of those methods to achieve the best results. For example, you can use the soundproof blanket and the door sweep together. This will ensure that no sound leaves the washroom via the hollow door or the gap at the bottom. 

Make The Door Thicker 

If you’ve tried the above methods and are not pleased with the results or you want to try out other methods, I would recommend thickening the bathroom door. 

How does the bathroom door sound and feel when you knock? Does it sound hollow or solid? If it’s hollow, there goes your sound problem. Hollow bathroom doors are thin, affordable but have poor sound isolation properties. 

In worse scenarios- hollow doors can even amplify the sound- sending echoes into other rooms in your house. In other words, these hollow doors can be compared to giant speakers keeping everyone in the house updated about your toilet activities. No wonder it was a concern for my girlfriend. 

There are two different ways you can solve this problem. The cheap method is using a soundproofing blanket (mentioned above). They are made of dense material design to isolate sound. If this method can work for you, I would recommend you purchase a soundproofing blanket with grommets to make it easier to attach the bathroom door. You will need a hammer and some nails to get the job done. Alternatively, you can install some hooks so you’ll just hang the blanket at will.

The pricier method is to knock down the old door and have a new one installed. You might need a handyman to replace the door- but make sure the new door is made of hardwood and it’s not hollow. 

If you live in an apartment or a rented space, you’ll need to talk with the landlord or property manager and see if they can replace the door. Some will agree to have the door replaced but others won’t- if they don’t you can resolve to the above soundproofing methods. 


Method#3: Soundproof The Bathroom Walls 

bathroom walls

If you have implemented the tricks above or combined two or more, then by now your bathroom soundproofing problem should be sorted. However, in most cases the problem doesn’t come from the bathroom door. Your bathroom walls might have some cracks which could be the origin of your problem. 

So what can you do? Below are some of the different techniques you can implement in your home to sound-dampening your bathroom doors. 

Seal Cracks 

Whether we like it or not, every wall eventually develops cracks. Like humans- we age and develop wrinkles, cracks in walls are signs of aging. Bathroom walls are prone to developing cracks fasters because they are regularly exposed to water. 

So what can you do when you find these cracks? 

If the cracks on the walls are small, you can simply fill the cracks using a joint compound. See different joint compounds on Amazon hereOnce you’ve applied the joint compound, leave it to dry and apply another layer the next day if possible. You can paint the repaired cracks to retain its original shape or fix a wallpaper to hide the repair. 

Add A Layer Of Drywall 

One of the best methods you can soundproof your bathroom wall is by adding another layer of drywall using a sound damping compound (a good example is green glue(there are some awesome green glue alternatives here) and placing a sound-isolating material Mass Loaded Vinyl in between. 

However, it’s important to note that this combination requires time and some technical knowledge and it’s also not the cheapest method. But compared to the other methods above, it’s one of the best in terms of noise reduction. 

The thicker and denser the new wall layer is, the more efficient it will be in isolating sound. Additionally, make sure that the added layer of drywall is waterproof to prevent the wall from absorbing moisture which could shorten its lifespan.

Cheap Wall Soundproofing Alternatives 

acoustic foam panels

If you don’t want to spend much money on soundproofing your bathroom walls, you can try these alternative tricks. You can take thick towels and position them on rods and shelves around your bathroom. The towels will absorb the sound that leaves the bathroom before it reaches other rooms in your house. 

Another cheaper alternative is using acoustic foam panelsHowever, because of the foam material, these panels are probably not the best way to soundproof your bathroom

Method#4: Soundproofing the floor 


Add soundproofing material to the construction

Floors in bathrooms are usually covered with tiles. Regardless of the size of your bathroom, the floor is essentially a hard and relatively large area the sounds can bounce off. 

Though it’s not practical to have that floor carpeted due to the amount of water and steam, there are still things you can do to improve the area. 

Most homes these days have harder flooring like wood floors or ceramic floors. As you know, hard flooring is a bit noisier, but there are simple ways to fix this problem. There are Rubber Mats you can buy that are water-resistant and will not only deaden noise from walking; it will also make the floor more comfortable for your feet and at the same time, keep them warmer. 

You can add extra soundproofing materials between the floor of the bathroom and the room underneath. However, it isn’t a practical option if you’ve already built and completed your house. 

Add some plush rugs 

Instead of adding a huge carpet, you can just add a few plush rugs around the floor. These will dampen some of the impact noises so you won’t hear as much of the walking in the room beneath. 

Luckily, these rugs come in many colors and designs to choose from so you won’t have a problem finding something that matches your décor. In most cases, they also come in packs of three where you have one rug for around the toilet, one for your bath entry, and one for the center of the floor. 

Use a floating floor 

A floating floor is another option though it’s not as practical. It’s a good way to block out the sound, but the effort is only ever worth it if the room under requires quiet at any cost. 

These aren’t attached to the floor which is why they don’t transfer as much sound. You don’t have to glue or nail them to the floor, so they are fairly easy to apply but only if you’re in the process of building your house. 

Having them installed in a bathroom that’s already furnished can be quite tricky and for the same reason a bit expensive. 

Method#5: Soundproof Your Bathroom Window 


Windows happen to be the second-largest noise culprit from the doors in any room. Depending on where it’s facing, there might be a lot of noise coming in or out of the bathroom through the window. 

This can diminish your solitude while soaking in the bathtub, especially if the window is facing a heavy-traffic road. Fortunately, there are several things you can do to soundproof your bathroom window easily without spending a lot of cash. 

To start with, you can re-caulk around the window casing using the green glue soundproofing sealant, which will reduce the noise coming in through the window. 

It won’t crack easily since it will always be flexible. Another thing you can do is to install insulated curtains in front of the window. This will help significantly in reducing the amount of outside noise coming into the bathroom. 

Install soundproof curtains in front of the window. These types of curtains do help a great deal in reducing noise transfer coming in from outside. Soundproof curtains are typically lined with fiberglass meshing to help reduce noise. The one I recommend and have always had good luck with are the Nicetown Blackout Curtains. 

Method#6: Seal The Bathroom Air Vent With Sound Dampening Materials 

Ventilation is one of the most vital parts in a bathroom. Therefore, it isn’t an option to soundproof your air vent, especially if it’s letting in a lot of noise into or out of the bathroom. 

To seal the air vent, you need to do the following: 

  1. Cover the vent with a soundproof curtain or blanket. 
  2. Add acoustic foam on the inner covers of the vent. 

Although this will allow air to travel through, it will help to deaden any sounds. You could also create a sound maze inside your vent.  This is the most effective method, but it’s also the most labor-intensive one. 

Method#7: Play White Noise Sounds 



If you are searching for the easiest and quickest solution to soundproof your washroom, you can get a white noise machine. You only need to buy the machine and use it to play white sounds inside your toilet. 

These sounds will not only conceal all the other noises in the bathroom but also soothe you. However, this method may not be the most effective way to dampen the noise from a bathroom that’s next to your TV room. But it is ideal if the next room is a bedroom. 

Now, let’s look at the last method! 

Method#8: Dampen The Echo In Your Bathroom


As I mentioned earlier, the bathroom is one of the rooms that produce the most echo in a house. 

This is because echo comes easily in a washroom through the solid flat surfaces, which allow sound to bounce freely around the room. Below are some ways in which you can soundproof a bathroom and block all echoes. 

Use Sound Absorbing Materials 

One of the simplest and cheapest things to do to stop noise from bouncing around the room is by putting sound-absorbing materials all over the place. You will find the Sound-absorbing materials in many varieties, and they will work impressively in reducing the echo. For instance, you can use the black egg carton-type panels, as most people do. 

Hang Appropriate Shower Curtains 

You can also absorb the echo easily by selecting the appropriate type of shower curtains. I recommend a fabric than a plastic material because it’s much better in absorbing the sounds. 

Put Towels In A Cabinet 

Another way to reduce the bathroom echo is by hanging towels to air dry at the back of the door. You can use an exposed or a closed cabinet for storing the towels. An exposed cabinet is excellent because even if it has no doors, the additional sheets will assist a lot in absorbing the noises. 

Use Paintings on The Wall 

The other method is using canvas paintings. These can work well specifically when there is low humidity level in the bathroom because they can hardly damage the artwork. By using the above methods, your bathroom will be much better and quieter without the echoes. 


How Much Does It Cost To Soundproof A Bathroom? 

If you want to sound isolate your bathroom, it’ll cost you between $200 and $7000. You’ll spend approximately $150-$400 for expenses related to insulating materials and $20-$50 for additional hardware tools required. 

If you hire an expert, you’ll incur approx. $150-$300– but that’s optional since techniques can be DIY. However, it’s important to note that the figures can vary because some people prefer expensive soundproofing materials while others prefer cheap options. 

Soundproofing Cost Per Square Foot 

According to the information I obtained from Remodeling Website, the average cost sound deadening per square is $1.73 and $2.40 for better soundproofing and $3.13 for the best sound dampening per square feet. 

  Basic  Standard  Premium 
Soundproof Insulation – Material Prices  $40.00 – $45.00  $50.00 – $55.00  $60.00 – $75.00 
Soundproof Insulation – Installation Cost  $125.00 – $135.00  $175.00 – $200.00  $225.00 – $265.00 
Soundproof Insulation – Total  $165.00 – $180.00  $225.00 – $255.00  $285.00 – $340.00 
Soundproof Insulation – Total Average Cost per square foot  $1.73 $2.40  $3.13 


However, you should keep in mind that- the figures are just an estimate because of the difference in material cost. 

Sound Dampening A Bathroom Door Cost 

The question about the cost of sound deadening a bathroom door is a tough one because of the different techniques of sound dampening your door and the varying cost of dampening materials. I consulted one of my next-door neighbors, a professional handyman, and here’s what he said. 

Andrew, dampening a bathroom door will cost you between $80 and $5000, it all depends on the material needed and where you buy them. 

I know that probably this is not the best answer to your question but you can always consult any repair company near you to get the exact amount. 

How Much Does It Cost To Sound Insulate A Wall? 

The cost to soundproof one standard wall (4m width x 2.3m height) generally includes $450 to $650 for materials, plus $250 to $350 for installation to complete the job, though the prices will be higher for soundproofing walls within larger rooms and for higher-performing soundproofing systems.

It’s worth noting that the wall soundproofing solutions supplied by The Soundproofing Store are suitable for a DIY install, therefore reducing any installation costs. The above cost estimates for wall soundproofing solutions do not include any costs for modifying any existing structures or surfaces. 

When To Hire A Soundproofing Expert 

While you can implement some soundproofing the bathroom techniques above at time you’ll need to hire an expert. Hiring an expert will help you save time and ensure that the job is done right. But only hire an expert if you can afford it, or if you don’t have time or technical knowhow. 

Soundproofing services cost around $56/hr. This usually only covers labor costs and does not include other variable expenses. 


Final Thoughts

I honestly hope that you now know how to soundproof a bathroom effectively to block any noise from coming into or out of the room. 

You don’t have to use all of the above tips; you can try a few and hopefully soundproof the bathroom effectively. 

As we have seen, it is much easier to sound dampen your washroom during the building process or when renovating the house than after construction. 

Therefore, do this whenever possible and follow the tips in this post to do it appropriately. 

Although you can be able to implement some of the tips explained here yourself, you may sometimes need to hire a soundproofing expert to help you do it correctly and save time. 

But hire only when you lack the technical know-how or time, and when you can afford it. Eventually, that’s how to soundproof a bathroom to keep your family, visitors, and yourself comfortable while in the house.
