What is the cost to cover a room 15' x 25'

Hi there, I apologize for my delay, and thank you for your question. For installation costs, please contact your local Lowe's and they will be able to get you matched with an installer to provide a measurement and quote. This carpet is currently priced at $0.98 per square foot - for the carpet alone, the cost would be 15 x 25 x $0.98, or $367.50 without tax. Please note that a carpet pad or cushion must be purchased separately, and the carpet installed over it. To assist you with choosing a pad, please note that per the carpet's warranty, the pad or cushion must have a minimum density of 5 pounds per cubic foot, and the cushion thickness should be a minimum of 3/8 inch and maximum of 1/2 inch. Thank you for considering Mohawk carpet for your project! Laura with Mohawk Flooring
