A remodeled basement gives you additional living space without changing the footprint 1 of your home.

Because the steps to finish the basement are similar for most of these purposes, you can gain a lot of additional space and use from your home simply by finishing this area.
Basements are a key part of many homes, but too many homeowners overlook their basement’s potential. While a basement can be used as a larger storage room, they are capable of so much more. While unfinished basements can function well as storage rooms, you can take steps to waterproof and finish your basement to transform it into a fully functional extra room in your home. If you want to finish your basement, here are some tips to help you along the way.

You can fit a full bathroom with tub/shower combination in a room that measures 40-square feet. However, on average, a smaller bath (with just a stand-up shower) or a half-bath usually needs to be about 30-square feet for comfort and functionality. Depending on the basement space and layout, you may be able to go with a larger 60-square feet or more bathroom space. Creating bathroom with a separate water closet may require 100-square feet or more.

Installing a bathroom in a basement costs more than installing a bathroom above ground. Costs can range from $2,500 to $5,000 on average, depending on the number of fixtures and whether the plumbing must be installed from scratch or if it’s roughed in already. Basement plumbing requires special considerations to ensure proper drainage and tie-in with the main sewer line, which may not be deep enough to allow the basement bathroom plumbing to use gravity the way above-ground plumbing does. Virgil Miranda’s Construction subcontracts all plumbing work. Miranda says that sometimes the toilet alone in a basement can cost up to $2,500 because sometimes homeowners need to invest in a toilet that does not use gravity but instead a macerating function to grind waste down to prevent clogging. Miranda estimates that each bathroom fixture in a basement costs $800–$900 on average, so a full, three-piece bath could cost $3,000 for the fixtures alone. Adding a kitchenette or wet bar sink adds more to overall refinishing costs. In addition, some basements require a French drain with one or more sump pumps, which can cost up to $10,000 on average, depending on how much ground the drain covers.
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.
Before walls and flooring can be added, the basement must first be professionally framed. Framing an unfinished basement can be very expensive; not only will it require a large amount of labor, but material costs are high as well. If you consider all the lumber your contractor will need to lay, plus crossbeams and studs, you will find that lumber is going to be one of the costlier aspects of the project.
The first step in finishing your basement it keeping it dry. Basements often deal with a lot of moisture vapor and hydrostatic pressure, which allow water into an unprotected basement. Because of this, any finished basement has to be waterproofed first. First, test your basement for moisture vapor so you know how much moisture you’re dealing with. There are homes tests you can do yourself or you can hire a professional to do the test for you.
An unfinished basement serves as a valuable blank canvas. The finishing process begins with basics such as hanging and painting drywall and installing plywood floors at a relatively low cost. Basement finishing means taking a space that currently is not livable and transforming it into a space you can use and enjoy. In an unfinished space, there may be nothing but a concrete floor, exposed pipes and electrical, and no walls or only the barest of wall framework in place. On average, the cost to refinish will fall anywhere between $6,500 to $18,500, or more for larger spaces.
