Adding a Bathroom to Your Basement
11/19/2019

Having a basement bathroom is not only convenient, it also increases the value of your home. Still, what do you need to consider before getting started?


Adding a bathroom to your basement provides some distinct advantages. It’s a perfect and essential addition if you plan on providing private bedrooms for guests or family. An extra bathroom also offers additional convenience and boosts the value of your home. However, the process of adding a basement bathroom, especially if your basement is already finished, does present a few hurdles you'll need to jump over.

Design restrictions

The first thing you should do when contemplating a new bathroom addition is to make sure you won't be breaking any local zoning ordinances or quirky neighborhood covenants. This includes considering what type of bathroom you want (bathtub, standing shower, half bath, etc.), and then determining if you have any existing free space you can use for it or if you’ll need to build an addition.

Drainage restrictions

The next step is to make sure you have the proper plumbing—it’s the most important thing to consider when planning a new bathroom. Basement bathrooms have certain plumbing restrictions that need to be fulfilled to function correctly. Those restrictions come down to the depth of your plumbing and the size of your waste pipe. Since most plumbing relies on gravity to help with the removal process, the depth of your plumbing plays a crucial role. The plumbing drain has to be deep enough for waste to make it through to the septic system. Modern homes typically have a larger pipe as a default these days, but it's something you'll need to either ask a plumber to check or check yourself before getting started.

How much does adding a basement bathroom cost?

In general, installing a downstairs bathroom can cost anywhere between $3,000 and $25,000. The exact price point of installing a basement bathroom really depends on what your floor plan situation is, i.e., whether or not you’ll need to build an addition for it, and how big of a budget you have. Some of the potential challenges that we previously mentioned can also affect the overall price.

Overall, is it worth it?

For the most part, yes—it is worth it to put in a basement bathroom. It adds an extra layer of convenience and increases your home’s value. However, be sure to check into all of the special considerations and potential issues before you get started!
