If you’re thinking about why you would even soundproof your bathroom, this article will help you understand why. Of all the rooms of your home, the bathroom is the one room that every one of us should soundproof. 

If you’re living in an apartment, or if you have neighbors living close by, then you don’t want to have a bathroom that’s not soundproof. You don’t want your neighbors to hear the sound of flushing down a toilet, nor do you want them to hear the sound of the faucet. 

Not only your neighbors, but you’ll also be doing a great favor to your family members by soundproofing your bathroom. 

Now that you know why soundproofing is essential and how it can benefit you, we finally can move to the step-by-step instructions on how to soundproof a bathroom. So, let’s get started. 

What Your Goal Should Be:

When you’re soundproofing any room of your home, there’s a general goal, and that is you need to block all sorts of sound that might come from outside, and the mediums through which the sound will travel outside.

There are two mediums through which sound may travel to or from your bathroom. Let’s talk about these. 

Through Air:

Sound travels through the air; we all know that by now. Most of the sound that’ll travel outside will travel through the air, and you need to make sure that this doesn’t take place. But how?

Sound travels through the air via vibration. When a sound is created, it travels in the form of vibrations. When these vibrations hit a solid object, only then do they cease. It means that you need to have solid walls, ceiling, and floor if you want to stop the travel of sound through the air. 

Through the Structures:

Then again, sound also travels through structures. The toilet you flush is connected to the floor, which is then connected to the beams that make up the entire structure of the building. Now, through these beams and the floor, sound may travel to the floors underneath and above you. 

This is why it’s very important to make sure that sound doesn’t travel through the structures. 

Things That You’ll Need to Get Started:

Soundproofing your bathroom won’t be very expensive. However, you’ll need to spend a considerable amount on the supplies. In this section, we’ll talk about the supplies that you need to get for building a soundproof bathroom. 

  • Soundproof blanket
  • Weatherstripping
  • Door sweep
  • Rubber mat
  • Mass loaded vinyl
  • Sealant
  • Foam pipe wrap

How to Soundproof a Bathroom: Step by Step Guide

1. Sealing the Walls:

Most walls of our homes are hollow. You can identify hollow walls easily. When you knock on the wall, if you hear a hollow thump, then it’s surely a hollow wall. Now, hollow walls aren’t that good at soundproofing. They don’t have any way of blocking the outgoing sound. 

If you don’t have solid walls around your bathroom, then it won’t be possible for you to reinstall new walls. However, there’s a solution that you can use easily. 

There are lots of different types of sound dampening mats. Now, if you have hollow walls around your bathroom, you can hang the sound dampening mats or blankets on the walls. Doing this will dampen the sound of the interior, and this will keep the sound from going outside the bathroom. 

2. Sealing the Door:

Sealing the door is one of the most important steps in soundproofing your bathroom. Just like the walls, the door needs to be solid. Now, replacing the door is far easier than replacing the walls, and it’s relatively cheaper as well. 

You need to check whether the door is solid or not. If the door isn’t solid, then you need to change it and replace it with a solid one. This won’t be that expensive, and it’s a must if you want to soundproof your bathroom. If getting s door is too much, you can use the weatherstripping and the door sweep to get the job done. 

3. Floors:

Sealing the floors will help you keep the sound diffuse through the structures. However, this step is only recommended if you have the budget. All you need to do is drape the floors with some sound dampening mats.

There’s another way of soundproofing the floor of your bathroom, but it’s a bit more expensive. Most bathrooms have porcelain tiles installed on them. Porcelain tiles are durable and waterproof, but they aren’t that good when it comes to soundproofing. 

If you have enough budget, then you can remove these and create a combination of cement board and tile. This will not only make your bathroom floor soundproof, but it will remain waterproof and weatherproof as well. 

4. Soundproofing the Pipes:

The pipes of your bathroom are one of the main structures that’ll carry sound, and they carry sound far and wide as they are hollow and cylindrical which allows them to create a lot of echoes. 

There are different ways of soundproofing the pipes themselves. You can either fill up the cavities in the pipe with some solid material, or you can wrap those specific places with absorption materials. For the absorption material, you can use copper or PVC. 

Then again, pipe rattling is a major issue in most buildings. You can easily get rid of this problem by mounting clamps that’ll hold the pipes steadily in place. 

5. Modify the Toilet Seat:

Toilet seats make a great noise if they fall freely. This is why it’s important to modify these as well. If you can manage some extra budget, you can get a separate toilet seat that comes with soft padding on the bottom. Due to the soft padding, the seat won’t make any noise once it falls. 

On the other hand, if you don’t want to spend this much on the toilet seat alone, then you can buy soft rubber padding and glues, and then you can install them at the bottom of the toilet seat in your bathroom.
