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 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.
For homeowners who are seeking fully remodel a basement, then they will be aiming to spend anywhere from $30,000 to $65,000. The varied range depends on the extent of the renovations that are made to the space. The addition of bedrooms, bathrooms, exterior insulation, electrical wiring, plumbing, flooring, furniture, light fixtures and the help of a contractor will all cause an increase in the price. Of course, the cost to remodel a basement will also depend on the square footage of the space.
Putting down a floor in your basement offers a host of different options that will depend on your wants and needs more than anything else. Carpeting in the basement can easily be installed by any professional. Any type of carpeting can be installed in the basement and is often the most economical option. Another popular solution to flooring in the basement is the use of tile. Although tile is a more expensive option considering both material and labor costs, tile can be very visually appealing in your newly remodeled basement.

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.

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.

The basement is often a catchall storage space for everything from garden equipment to out-of-season clothes, holiday decorations, and memorabilia. As you remodel to make the most of your basement's square footage, plan for attractive, well-designed storage, too. Here, a wall of built-in ceiling-height storage closets give the illusion of a sleek white wall, but provides tons of space for knick-knacks and seasonal decor.
Once you’ve completely waterproofed and your basement is protected, you can move on to the room’s interior.

Radiant heat costs around $6,000 - $14,000 depending on the method used.
