The average cost of basement remodeling varies based on the square footage of the basement space, if structural changes are needed, and if you are adding in elements such as electrical work for a kitchenette or plumbing for a half bath. Other factors in cost include whether you have design plans already and what work you want done on the finishes such as trim and flooring. Here’s a breakdown of the various cost factors.
Installing all of the necessary plumbing and electrical work while walls and floors are unfinished will result in savings.Starting from scratch doesn't require demolition, which can save you around $2,000. Framing may be necessary to define rooms and spaces. System upgrades usually call for minor expansions to the HVAC and electrical systems, but not adding plumbing. The bulk of the cost, however, is in flooring and finishing. After wrapping things up with carpeting, drywall, and ceiling material, you can expect to pay anywhere from $6,500 to $15,500.
Transform your basement into a multi-activity area dedicated to have loads of fun. Oversized bean bag seats for relaxing, reading books or just a space for adults to spend quality time with the kids and keeping an eye on them while they are playing. Create a space for children’s games and toys by having a foos ball table and some miniature rocking chairs. Light tone laminated wood flooring is a good choice for this basement play area.

While decorative concrete may cost more than some other types of flooring, its proponents point to the long life expectancy of this material. Even cracks in the floor can be considered an attractive rustic feature as long as they do not reflect structural problems. Those concerned by the slippery nature of high-gloss sealers can add a non-slip additive to sealer or stain before application.

Whether your basement is for a game room, man cave, yoga retreat, or movie room, this room has the potential to be the best room in the house. What color you chose depends on a few things, the most important being what is the tone that you want to set for the room? Followed closely by how the room will be used and who will be using it most. The color is really going to set the stage for this space so you want to make sure you have the right color before you commit it to your walls.
Because basements are usually below ground level, water seepage and moisture issues have to be resolved before construction can start. Prior to creating a project bid, most contractors will inspect the area to check the interior floor and walls for dampness and make sure the exterior of the foundation is in good shape. Depending on how watertight the basement and foundation are, it may be necessary to protect the basement from future water damage after it’s finished, often through the installation of sump pumps. This work can cost anywhere from $700-$3,000, depending on what needs to be done. Learn more about basement waterproofing. To help prevent moisture problems, homeowners can clear downspouts and gutters of debris to ensure that they help keep moisture away from the foundation.
After your new bathroom is complete, or you have remodeled an existing space, get it inspected to ensure all plumbing and electrical installation are done correctly. If your bathroom needs to be installed from the ground up, expect to pay somewhere between $6,000 and $15,000 for the entire project. If your basement is already finished but does not yet have the necessary plumbing for a bathroom in the space, you can expect to pay between $200 - $500 to hire a plumber.

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.

Homeowners wishing to enclose basement appliances should take note of air-supply requirements for both the furnace and water heater, which are powered by electricity or natural gas, oil or propane. Fuel-burning appliances use room air for combustion and require an unrestricted air supply. Any enclosure requires installation of a louvered door between living areas and the furnace room to ensure an adequate air supply and ventilation in your basement. Without sufficient air, a house may fill with dangerous gases, including carbon monoxide or radon.


Many new homes are built with an unfinished basement. This saves money up front in construction costs and gives a family the opportunity to grow into their home.

No matter what the reason, finishing a basement can come with a considerable price tag. However, it's generally a good investment as a basement remodel fetches 80% to 90% of its investment cost at resale.
