The basement space in a home promises additional storage or living space that can be used as the owner pleases. Adding an extra room in the basement—as either a study, gaming room, or even a spare bedroom—will significantly increase the efficiency and value of your home.

If you decide to convert your unused basement into an extra room, then you will probably need to install a bathroom. This makes the spare room more convenient to use as the occupants do not need to go up at least one flight of stairs to access a bathroom.

As such, you will probably need to know how much installing a bathroom in the basement will cost. In this guide, we will discuss the cost implications of adding a bathroom to your basement. On average, you will spend between $12,000 to $28,000 to add a bathroom to your basement.

Gone are the days when basements were left as abandoned spaces and caverns for spiders and bugs.

More homeowners are now realizing how important finishing this part of the home is. A finished basement can serve as an extra bedroom, entertainment space, study, or even a home gym.

The following are some of the benefits of installing a bathroom in your basement.

Increases Home Value

A finished basement, even without a bathroom, considerably boosts the resale value of your home. Installing a bathroom in your basement significantly improves the value of your home in the market, making it a hot seller. Homes with two or more bathrooms often sell faster than those with single bathrooms.

Bathrooms always offer a good return on investment and they increase the property value by between 10% and 25% depending on the size, finish, and the location of the home.

Convenient Access

Imagine having to constantly run up at least a single flight of stairs every time you get a call of nature. Inconvenient, right? Adding a bathroom to your basement makes it a more livable space for the occupants.

Having a bathroom installed in your basement also offers additional privacy both for the basement users and other occupants of the house. The thing with bathrooms is that everyone uses them, so an extra bathroom is never a bad idea.

Creates Additional Livable Space

If you decide to have your basement as a spare room, either as a bedroom, study, entertainment room, or a home gym, having a bathroom makes it even more livable.

If the space is habitable independently of the rest of the house, then it raises the total value of the property. And as we mentioned earlier, prospective buyers are more drawn to homes with two or more bathrooms, meaning that the return on investment is guaranteed.

Building Permits

Depending on the location of your property, it’s likely that adding a basement bathroom necessitates a building permit from the local authorities. This ensures that any work done is completed according to the building code. The cost for permits usually ranges from as low as $35 and can go as high as $2,000 depending on the location.

Drilling and Demo

If you have a finished basement, the addition of a bathroom will likely require some demolitions to allow construction to take place. In addition, if there is a concrete slab, you’ll have to account for the cost of drilling the concrete to allow pipes and drains to pass through.

Adding a bathroom in your basement not only offers more convenience for the occupants and users of the basement but also boosts the property value significantly. Bathrooms offer a guaranteed return on investment when you eventually decide to sell your home.

Installing a basement will increase your home’s appeal to the occupants and potential buyers alike.
