A: Thank you for your submission. The average cost for partially finishing a basement will primarily depend on the size of the area you are finishing and the design elements for your project. With our company, the cost for our basic basement finishing option is $9,999 for up to 800 square feet. For an average size basement (a basement for a 2,500-3,000 square foot house), the cost to finish a basement will range between $13,000-$14,000 for a project that does not include a bathroom, and $22,000-$24,000 for a project that includes a full bathroom.
