This can also help to insulate the space and reduce noise levels. If you have a concrete basement, it’s important to use waterproof flooring that can withstand moisture.

Step 7: Add Lighting

Proper lighting can make all the difference in a basement space. Install dimmable fixtures or natural light sources such as skylights to make sure your rooms are bright and inviting. That way, you can adjust the lighting to suit different activities. This can also make the space look bigger and more inviting.
