The Average Cost to Add a Bathroom by a Conversion Space

Whatever reason lies behind your desire to get an additional bathroom at home, you can embark on the project once you find an unused space of 20+ square feet. But even 15-20 sq. ft. can be enough for a powder room. As the cost to add a half-bathroom or a full one hinges significantly on the specific location you want to convert, let’s consider the most popular options:

• Attic. It’s one of the most underrated places that provides ample space for a bedroom-bathroom combo. Here, you can unleash your creativity and enjoy design flexibility. The cost of a bathroom addition to the attic can fall between $7,800 and $35,000, depending on whether the space has already been finished.
• Laundry. Sacrificing a laundry room for a bathroom is a smart and cost-efficient move, as it has the necessary plumbing and electrical lines, making the conversion a cinch. You may only have to take care of the structural reinforcement and installation of an appropriate ventilation system. The project can run from $4,900 to $12,200. 
• Basement. Converting a part of the basement into a bathroom can be tricky due to installing a sewage ejection system. But you can add in a truly luxurious bath with a tub and/or a shower. The cost to add a bathroom to the basement lands between $8,000 and $22,000.
• Garage. Those with oversized garages may find it feasible to cut off a part. But the project is complex, as you’ll have to extend plumbing lines from the house. It can be challenging because of a concrete floor. The cost to add a bathroom to a garage starts at $9,000 and can go as high as $25,000+. 
• Bedroom. If the size of a bedroom offers flexibility, you can get a marvelous bathroom with desirable amenities at hand. However, installing plumbing lines and drains can make the project more sophisticated, as bedrooms are not usually designed with these things in mind. Your expenses can be anywhere between $16,000 and $42,000+.
• Upstairs space. The project’s complexity can be similar to that of a bedroom, as structural considerations for plumbing and drainage need to be made. On top of that, it’s worth taking care of structural reinforcement to your floor. The cost can run from $7,500 to $19,000.
