Finishing a basement can cost between $25–$50 per square foot on average, depending on how the basement is finished, whether any challenges come up or whether there are special circumstances with the project. For this reason, a 1,000-square-foot basement can cost up to $50,000 or more to finish. Virgil Miranda of Virgil Miranda’s Construction, a general contracting company based in New Bedford, Massachusetts, says it can be tricky to estimate remodeling jobs based on square footage alone, due to the variance in each job. Larger basements may have a lower cost per square foot than tiny remodel jobs.
According to real estate agents and appraisers, a bedroom must have a door, window and closet. Adding a closet to your basement bedroom is crucial to adding value to your basement addition. There are a few components that will affect the cost, the size of the closet being the biggest. The average cost to install a closet is $1,779, with most homeowners spending between $1,272 and $1,917. More than likely, your closet cost will be lower seeing that the size of the closet won’t be nearly as large as your master bedroom or other main bedrooms.
Material Costs - In addition to the cost of framing and installing drywall to a basement bathroom, material costs can include: ceiling, flooring, paint, trim, toilet, sink, vanity, all fixtures, tub/shower surround, lighting, and all finishes like towel racks. Plumbing and electrical supplies also factor in to the final budget. Many material costs depend on type of product selected, the brand, and how high-end it is. Heated ceramic floor tiles cost more than basic vinyl tiles.
When putting a wall over a recently constructed frame, sheetrock is the industry standard for a paintable and more durable option. It can help insulate the room and generally lasts a long time when maintained. If you are trying to significantly drive costs down, go with paneling. It is very light, inexpensive and pre-finished in a variety of different sizes and types. Labor costs may also decrease because paneling is easier to transport and work with.

Your foundation should be inspected prior to finishing your basement. You don’t want to cover up any structural damage that would be identified in an inspection by installing framing and drywall. If items such as pipes have rust, the problem may be humidity instead of a leak, but it can be just as damaging. Waterproofing the basement and using a dehumidifier helps reduce dampness and the risk of mold development.


Carpet use to be the gold standard for basement flooring. Its soft and homey texture blended perfectly in basement remodels across the country. Furthermore, according to our flooring cost estimator, carpet is cheaper than both tile and hardwood flooring. However, carpet has lost recognition over the years and when it comes to flooding, no flooring option is more expensive to fix than carpet.
