If you want to increase the amount of living space in your home, remodeling your basement makes a lot more sense than adding on a new addition. A finished basement has an ROI of around 70%, making it one of the better investments you can make in your home. A typical basement remodel costs around $90 a square foot, assuming moderate decor and finishes. With the average project size of 600 square feet, this puts the cost of the average basement remodel around $55,000.
The average cost to add a bathroom to a basement is $7,600 or between a range from $2,500 to $12,400. A basement bathroom addition can add 10% – 20% to the value of your home. Drainage and plumbing will be your two most significant cost factors. For a small basement, a half-bath with no shower or tub is adequate, while a bedroom suite needs a full bathroom.
Adding carpet to your extra bedroom is a great way to separate this space from your basement, and make the room feel like an escape. There’s nothing like getting up and putting your feet on a soft carpet. Another pro of carpet is that it’s cheaper than hardwood flooring, or other popular flooring options. The average cost to install carpeting is $1,628, with homeowners reporting prices between $862 and $1,831.
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.
Nationwide, basement remodeling costs average $52,931-$74,974 for a project which includes a 20x30-foot entertaining area with wet bar, a 5-x-8-foot full bath, 24 feet of partition to enclose a mechanical area, painted walls, ceilings and trim throughout, exterior insulation, doors and electrical wiring, according to the annual cost vs. value report by Hanley Wood .
Search the pro’s contractor’s license to verify they are in good standing with the state board. As an example, in California, search the California State Contractors Board to learn if the license is up to date, if they have any legal action against them and if the contractor is in good standing. Some states only require contractors licenses for residential projects based on price, so research your region to be safe. For more information on smart hiring, check out our safety tips.
Concrete will always crack eventually, and any existing foundation must be inspected before a basement finish to see if it’s in good condition. Minor foundation crack repairs cost $620 or more to fix, while major repairs that require hydraulic piers can cost $10,000 to $15,000. If your foundation is sinking, mudjacking costs $3 to $6 per square foot to raise the slab.
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.
