Planning is the first stage with any basement bathroom installation. For a basement that's designed as a recreation room, work space, or kids' play area, a half-bath (stool and sink, but no shower or tub) is adequate. A basement with bedroom or en suite needs a full bathroom. Knowing how you plan to use the basement living space typically dictates the functional purpose of its bathroom.

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.


Cold water running through the basement in plumbing pipes can also create condensation, and as the drops of water collect on the outside of those pipes they make the basement wet. To fix that simply wrap the pipes with inexpensive foam insulation found at your home improvement store. You can apply it without any tools except a knife or pair of scissors to cut it into the lengths desired, and then tape the seams with insulation tape. Insulate the hot water pipes, too, to prevent loss of heat as the water travels through your basement to the upper floors of your house. That will also help to reduce your energy bills.
A finished basement is not always the same thing as a designed basement. Sometimes, the basement begins with the basics: walls, a ceiling, lights, and a floor. Gwen Hefner and husband Micah wanted to turn their tiny, airless basement space into a comfortable mancave. They had the basics to start with. The next step, Gwen says, would be a true test to her design skills.
Storage is key in a multipurpose space. There are several storage units throughout this basement. An IKEA cubby bookcase is a perfect fit for the office niche. Orange baskets corral small items and add spots of color to the basement's storage solutions. Stock cabinetry did not fit in the bar or media spaces, so the homeowners opted for costly, custom cabinets. Experiment with different types of storage units in your home to utilize every possible space.

With a level, smooth surface you also have tons of other flooring options, based on your decorative scheme and your budget. A relatively inexpensive and easy option is carpet, with a carpet pad beneath it for added comfort and to keep your feet warmer in winter. Peel and stick vinyl tiles are another option, and they come in various styles, colors, and price ranges for any budget.

Drywall must be applied to any framed basement walls you have and must be applied to any additional walls used to create your basement bedroom. A standard 8’ by 4’ panel will cost between $10 and $20, depending on the thickness. The cost to install these panels varies, but most homeowners report spending around $1.50/sf. The total cost of your project will range between $1,152 and $1,982, with an average cost of $1,915 to install a wall.

When it comes to basement renovation, the national average price for a finished basement ranges between $5,000-$70,000. That said, unless you're adding in an elaborate home theater or building in separate rooms with high-end finishes, most Thumbtack customers report paying, on average, between $5,100-$7,150 for their remodeled basement. A finished basement provides you additional living space, increases your home’s value, and offers great return on investment when it comes to home improvement projects.
If time is critical, consider a basement finishing kit. A finishing kit has insulated wall panels, and some include a walkable flooring surface and ceiling material for DIY installation. Depending on the size of your basement, these kits can be installed in a weekend. However, the floor won't be carpeted, the walls won't be painted, and there will be no electrical or plumbing. Other features such as doors, trim work, and more also need to be added.
Sourcing supplies, clearing debris, and doing prep work can all help you save on basement costs. Consider what skills you have and talk with your contractor about what will shave money in each area. You may have the tools and strength to demo walls, which can save you several hundred dollars. Sourcing the materials for the pro takes this task off their labor time and saves you money. Doing prep work and finish work is also a way to cut down on total cost. Painting the walls yourself at the end of the project could save you hundreds of dollars. Negotiate all these aspects before signing your contract.
