Plumbing costs $400 to $1,800. You’ll need it for laundry rooms, bathrooms, steam rooms and wet bars.
Insulating a basement costs $500 to $1,500, usually using fiberglass batting. A basement retains higher humidity than most other areas of your house. So, you’ll want to let the walls “breathe” so moisture doesn’t cause mold growth.
Drywall installation costs $1,000 to $2,900. You’ll only need it for new walls, not the existing finished space. Adding electrical and plumbing means you might need drywall repairs. Basement drywall repairs cost $300 to $850. Those fees often get included in the overall project bill.

You’ll hear renovations and remodeling used interchangeably. Renovation means to restore your basement to a like-new condition. So, you’ll probably skip new walls and rooms, opting to refinish the surfaces.
Some renovations specific costs include:
Your home’s value increases by about 70% of the investment you put into your basement. However, you don’t want to put high-end granite counters in the basement if you only have laminate upstairs. Match the quality of your basement to the rest of your home for the best ROI.
DIYing your basement remodel depends a lot on your experience level. And some parts of the remodel make better do-it-yourself projects than others. For example, if you have the time, hardwood floors make for a great weekend project. But you’ll need experience doing this and the tools to get it done.
Hire a pro for larger projects or anything involving plumbing or electrical, like installing a bathroom. Also ask your pro if you can do anything to reduce costs, like demo and cleanup work.
If you must call in a pro to redo anything, you’ll spend more overall. Before starting any project on your own, consult a local basement remodeling contractor.
