Bathrooms can be very noisy places due to exposed pipes, family members taking showers, blow-drying their hair and so on and so forth. Just because the walls in your home have insulation, including the ceiling does not mean that there is insulation in the interior walls to reduce the noisy sounds. In most cases, interior walls have no insulation at all.
There are many different ways you can soundproof your bathrooms including adding insulation or by doing a few simple maintenance things that are very simple. Insulating the interior walls is the best answer. If you would like to do to it yourself, there is a simple method even though you will need another person to help. You can choose to go through the bathroom wall or the other wall. In most cases, as long as the pipes are not in the wall that needs the insulation you can go through the bathroom wall. It also depends on how many walls you need to soundproof. In some cases, the guest bathroom may be beside not only the dining room, but also a bedroom to one side or the other. You may wish to insulate more than one wall to give the person in the bathroom a bit more privacy. No matter, what the case you will should be able to add insulation through the bathroom wall.
The best insulation to use is called cellulose insulation. Cellulose insulation is nothing more than shredded newspaper treated with fire retardants. This insulation can and will fill and pack the stud cavities. What you will need is a stud finder, bags of cellulose insulation, a drill, and an insulation machine. You can find all of these products at a home repair center or a retail store such as Home Depot. You may even be able to rent the insulation machine.
Now, find the studs. Next, drill a hole in between the studs on the wall you wish to insulate. Measure the nozzle on the insulation machine in order to know what size to make the hole. Drill a hole about 4 to 6 inches down from the ceiling. The insulation machine needs to be outdoors with the hose running in through the window or a door. One person will need to be outside with the insulation machine to operate the machine and fill the hopper with insulation and the other person holding the nozzle in the wall to fill the cavity with insulation. When the insulation is at the top of the hole, you will be done. Be careful not to overfill. Once you see the insulation coming out of the hole, stop the machine. You can now repair the hole and paint the wall.

Smooth surfaces allow noise to bounce around the room whereas rough surfaces to do not. If you do not wish to carpet the bathroom, you can use mats or rugs. These items will also reduce sound, but will not soundproof as well as insulating the interior walls. Another option is the use of a sound conditioners. A sound conditioner or white noise machine will help mask all types of bathroom sounds. The sound machine should be placed outside of the bathroom door for maximum effectiveness. White noise machines produce sounds similar to those of a box fan or air conditioning unit and will help mask most sounds coming from inside the bathroom.
