How Much Does It Cost to Finish a Basement in 2025: Real Figures and Tips for Saving

Have an unused basement and want to do something with it? For example, a home office, gym, guest room, or rent it out. That’s a great plan. However, before any changes, the question of price arises.

Let’s look at real figures, smart planning tips, and why choosing the right builder makes a big difference.


Denver Basement Finishing Prices

In Denver, finishing a basement will cost between $40,000 and $90,000 in 2025. Size, design, and features all affect cost. This is a basic cost breakdown:

  • Basic ($40,000 – $55,000): paint, ceiling, drywall, flooring, lights, and framing.
  • Mid-range ($55,000 – $75,000): storage, recessed lighting, improved flooring, and bathroom.
  • High-end ($75,000 – $90,000+): custom cabinets, smart technology, a theater, a kitchenette, a bar, and a luxurious bathroom.

Due to local labor, building codes, and the necessity of waterproofing in Colorado’s climate, prices in Denver may be slightly higher.

What Else Affects the Price?

The final cost could differ based on a number of additional factors besides the materials you select. Namely:

  • Inspections and Permits for construction, plumbing, and electrical work. They cost time and money but keep your home safe.
     
  • Waterproofing and Foundation – If your basement has any moisture issues or cracks, you need to fix them first. This is a must before you start finishing the space.
     
  • HVAC and insulation – In Colorado’s changing weather conditions, heating, cooling, and quality insulation are essential.
     
  • Design choices – Open layouts cost less. Custom features, additional rooms, and bathrooms are more expensive.
     

How to Save Money

A basement renovation is a big investment. Plan it carefully, and it will help you stay within your budget.

Money-saving advice:

  • Plan the layout early. Simple floor plans cost less to build. Avoid unnecessary walls.
     
  • Use durable mid-range materials. Painted cabinets, quartz worktops, and vinyl flooring provide a stylish and affordable alternative.
     
  • Place new bathrooms or wet bars near existing pipes.
     
  • Finish in stages. Walls, flooring, and electrical should be completed first. Then upgrades.
     
  • Work with local experts. A Denver company like Arch Design & Build knows local codes, permit rules, and efficient construction methods.

ROI: Is Basement Finishing Worth It in Denver?

For many homeowners in Colorado, finishing a basement is not just about comfort. It’s also an investment. According to remodeling data, a finished basement in Denver can return 70–75% of its cost when you sell the home.

The return can be even higher if you add a rental unit. Denver has strong demand for rentals, and a legal basement apartment could bring in steady monthly income. That makes basement remodeling a lifestyle upgrade and a smart financial move.
