Preparing Basement Bathroom Plumbing

Placing a basement bathroom in your home isn’t as hard as it may sound. There are a few things you need to consider since gravity will not be on your side. Here are a few things you can do to prepare the plumbing in your basement for a bathroom.


When a toilet is flushed several things happen. Typically a valve opens and flushes water in to the toilet bowl, forcing the waste to wash down in to the sewage pipes. Gravity pushes this down in to the pipes. In a basement there isn’t really anyplace for the water to go since you are at the lowest point in the home. You will need to prepare for either an up-flush toilet or a sewage ejector system to overcome this.


If you plan on installing a full bathroom with a tub or shower, you will need to consider the drainage issue. Again, gravity will work against you. You will need to either install a new drainage system or find a way to tap in to the one already in place if it’s lower than the lowest point in the basement.

Once you overcome these issues the rest of installing a bathroom is just like installing it in any other room in your home.
