The bathroom is an intimate space where you do a lot of things. You don’t want to broadcast the noise to the member sitting just outside the bathroom wall. But unfortunately, it happens many times because of the construction and location of your bathroom.

For instance, flushing toilets can disturb and annoy guests if the bathroom is just near the living hall. It even disturbs your privacy.

How To Soundproof Bathroom?

The bathroom can sometimes be louder, especially when you shower or flush the toilets. This noise can be pretty annoying for guests or other family members in your household. Well, you can solve this problem by soundproofing your bathroom. Let’s look below how to soundproof bathroom.

1. Put A Sound Blocking Door Sweep

The door sweep is a door mat that consists of sound-absorbing materials. Try to place it just on the bottom of your bathroom door. It will help in dampening the bathroom noise. Remember, the most effective one will be a rectangular door sweep to absorb sound.

2. Use Weather Strips

You must check gaps or cracks between the bathroom door panel and door frame. If you find any gap, sound waves can easily escape through it. One of the most effective and cheapest solutions is to use weather-stripping tape. 

It seals all cracks and gaps in the door and helps to muffle the sound. Try to choose a rubber weather strip for sealing the gaps and cracks in your door. The rubber strip is a versatile product that you can apply not only on the entire door frame of your bathroom door but also on windows.

It is quite easy and simple to apply weatherstrip. Your first duty is to clean the entire door frame of your bathroom and then take measurements. You must cut the weather stripping according to the measurement, remove the adhesive backing, and install it on the entire door frame.

Below are a few tips you keep in mind while installing a weather strip.

  • Don’t leave even the tiniest gap or crack, as sound waves can easily pass through it.
  • You can test whether you have correctly installed weather-stripping tape on the bathroom door. You need first to switch on the lights just near your bathroom. You can then close the bathroom lights and then the bathroom door. If you find any light source entering the bathroom from the door, then there are still gaps or cracks, and you need to address them.

3.Change Your Bathroom Door

Today modern construction doesn’t care about the noises in the bathroom. Most apartments usually have bathrooms attached to the living hall or bedroom. Hence the noises in the bathroom can easily disturb guests or other household members.

The bathroom door constructed today is hollow from the inside. It is the reason why sound can quickly go outside and disturbs everyone.

So knock on your bathroom door? How do you feel? The hollow ones are usually composed of thin and light materials.

 They are inexpensive to install in the bathroom but poorly absorb sound waves. A hollow bathroom door can update your guests or other family embers about your toilet activities. Well, you can solve this problem by changing your bathroom door. 

Choose a solid one, particularly hardwood, to dampen most of the noise created in the bathroom. But it is expensive, and you need professional help to install the door.
