Finishing a basement is widely considered one of the smartest remodeling investments you can make, often returning 70% or more of its cost in added home value. In 2026, a standard basement finish in Texas runs $30–$50 per square foot, while a premium build-out with a bathroom, wet bar, and custom finishes can climb to $50–$75+ per square foot.
