The cost to lay concrete in a 20ft x 20ft basement room can vary based on location, labor rates, and material costs, but a general estimate would be between $4 to $8 per square foot for basic concrete. For a 400 square foot area, this translates to approximately $1,600 to $3,200. Additional factors like reinforcement, finishing, and site preparation may increase the total cost. It's advisable to get multiple quotes from local contractors for a more accurate estimate.
