Why To Soundproof a Toilet?

Bathroom noise is a common cause of disturbance and there aren’t many ways to avoid these sounds. However, there are a few you can do to dampen these sounds, and the best thing is to soundproof the toilet.

You would never want your family members or guests sitting in the living room or TV room to hear toilet sounds. This not only embarrasses the person inside but also makes it awkward for the people outside. 

Nowadays, keeping the bathrooms well-insulated and soundproofed is equally as important as keeping them hygienic and clean. Modern houses have attached bathrooms and this further signifies the need to make them soundproof.

You wouldn’t want your sleep or nap to be disturbed by your spouse, siblings, or parents while they are doing the unavoidable. So, it is best to soundproof your toilet and make things more peaceful and less-awkward.

Annoying Sounds of the Toilet

Bathroom sounds don’t always come when it is occupied. Many irritating and disturbing sounds may come even when it is vacant. These may be due to faulty water pipes, a noisy flush system, or a loose toilet seat. 

To get rid of these annoying sounds of the toilet, you need to soundproof the toilet. In a way, the toilet is nothing but one small hollow where every minute sound echoes and resonates. Even the sounds that aren’t annoying or loud appear irritating and noisy.

The only possible way to minimize these bathroom sounds is by using sound-absorbing materials. You can add them to the wall, door, window, ceiling, and flooring of the bathroom or you can soundproof the components of the bathroom such as toilet bowl, water pipes, sink, and drain. 

For the best results, it is best to soundproof both the toilet and its components. Although, even a few measures in the right direction can help you alleviate the noise problem to a certain degree.

How to Reduce Echo in a Toilet?

As mentioned above, echo or resonance is the biggest problem in a bathroom or toilet. The simplest way to cut down echo is by adding sound-absorbing materials. Their function is to absorb sounds before they strike the hard surfaces and bounce back with greater intensity.

Yes, we all know we can’t just carpet the bathroom to absorb all the annoying sounds. While we can use creativity to do things that help us achieve even better results. Adding a rug is never a bad option while using sound-deadening curtains or blankets is among the most effective ones.  

However, there are a few things you need to consider while choosing the sound-absorbing materials to soundproof your bathroom. For instance, you must factor in humidity, moisture, and water-exposure. 

Among these, options like cork flooring tiles lead the rest as they are best-equipped to combat the bathroom heat and humidity. In truth, their soundproofing ability is only second to one and that’s rubber. 

You shouldn’t also forget about the ceiling when you are searching for ways to dampen echo or resonance in your bathroom space. Similarly, holes, crevices, and cracks in your bathroom should also be sealed to help you achieve the desired result. 

In a bathroom space, every little thing matters from light switches to electrical sockets and you must do what you need to do to soundproof them correctly. Here you can try installing acoustic insulation inserts. If acoustic isn’t possible, at least use standard insulation inserts. 

Your bathroom is a den of pipes and even one faulty piping system can make it particularly noisy. It is essential to make sure all the pipes are tightened up and it is best to cover them in acoustic pipe wrap. This dampens the pipe noises that may come due to air pockets within or excessive water pressure.

Additionally, you must also keep an eye on your plumbing system as it shouldn’t make any notable noises during faucet use or toilet flushing. If it does then it’s probably due to water hammering. This is a problem whose early identification is essential to prevent damage and can be easily resolved by refilling the air chambers or adding pressure regulating equipment to the system.

Install Padding

Installing padding on the toilet tank and the seat is an effective way to dampen the noises of a toilet. Every time the toilet seat hits the tank, it makes a loud thud and padding is what you need to avoid this noise. If you use the toilet without a lid, the first thing you need to do is to get a lid and pad it. 

Install Sound Dampening Bumpers

The sound-dampening bumper is another great thing you can add to the mix to curtail the bathroom sounds. Sticking these bumpers on the tank at the place where the seat hits the tank is the best way to dampen the lid striking sounds.

Additionally, you can also try adding the bumpers on the underside of the toilet seat so it makes less noise when it drops down. These techniques are perfect to cut down the annoying sounds of porcelain-on-porcelain contact that echoes around every badly insulated bathroom space.

Insulate the Tank

Insulating a tank is a great solution especially if you have a loud flush. Sometimes you can even hear water accumulating inside the tank and the only way to quiet it down is by insulating the tank.

You can use acoustic foam to insulate the tank and it is best to stick it around the toilet tank’s top edges for the best results. This not only absorbs sounds but also makes the lid even more tightly sealed. 

Check the Pipes

It isn’t uncommon to hear your pipes making a lot of noises and this issue is particularly related to a faulty piping system. You can try to quiet it down by tightly clamping the inlet pipe and screws or you can regulate the water valve. This often solves the problem and quiets it down. 

Install Quiet Fill Flush Valve

Normally, toilets make a lot of trickling sounds when the water is filling the cistern and what you need is a quiet fill flush valve to sort this out. These valves are designed to feed the water with an outlet pipe back into the cistern. 

Regulate Water Inflow

Sometimes, the water inflow speed is the cause behind excessive toilet sounds and you can easily turn the sounds down a notch by regulating the water inflow. Slowing down the water inflow rate while filling the cistern often helps quiet down the toilet sounds.

Soundproof the Toilet Walls

There are only a few things you can do with the toilet seat, tank, pipes, and other components. They do help but you have to do something extra to stop sounds from escaping the toilet walls. The best thing, to begin with, is to soundproof the toilet walls.

Our home interiors walls are hollow and ill-equipped to absorb or block any sounds. That’s why we need to adopt soundproofing techniques and methods to insulate them the right way. Adding mass-loaded vinyl or cork tiles are a couple of effective ways to insulate the toilet walls.

Some other tricks do work brilliantly in soundproofing the toilet walls. These include adding a layer of drywall, sealing the holes and cracks, and strategically positioning towel racks.

Soundproof the Toilet Door

Soundproofing the toilet door is a mere necessity if you desire to have a soundproofed toilet. The normal doors are usually hollow-core doors with nothing to block or restrict the penetration of sound waves. 

You have to get these replaced by solid-core doors if you want to block the escape of toilet sounds. Adding a layer of mass-loaded vinyl is another effective way to add mass to the doors and make them better at soundproofing.
