Cost to Add a Bedroom and Bathroom to a House
When built as a primary suite, bedroom and bathroom additions are $62,500 on average. The price can climb well over $100,000 if you choose a luxury design and high-end finishes, like hardwood flooring, French doors and custom showers.
Cost to Add a Bathroom
The cost to add a bathroom is $42,500 on average. The bathtub alone will run you $740 to $1,400 to install, while a shower-and-tub combo is closer to $3,000 for labor and materials. With all the needed plumbing fixtures, pipes, and finish materials, bathrooms are much more expensive to build than the bedroom area.
General Contractor Costs
When hiring a general contractor near you, expect their services to run 10% to 25% of the project total. If your addition is in the average price range, expect $6,250 to $15,625 of the total to go to your contractor. For their fee, these contractors will order the right materials, manage all needed subcontractors and schedule each task in the ideal order. Their services will ease your stress as they take on the responsibility of making sure all the work is done to code and by the deadline.
Structural Engineer Rates
Structural engineer services cost anywhere from $200 to $1,300. Their charges are included in the total cost as an hourly rate of $100 to $150 or a flat fee equal to about 8% of the project. Many accept a payment plan starting with 25% up front, but you should always get the agreement in writing first. You will split the rest evenly between the remaining two payments. These professionals are well worth the price since they make sure your addition is structurally sound.
Cost to Hire an Interior Decorator
Interior decorators charge $2,000 to $11,000 to help spruce up the space. You can bring in this expert once the room builds are complete and you are ready to decorate. They will help you pick out a color scheme, buy furniture and thoughtfully arrange your décor.
Interior Designers
Interior designers also charge $2,000 to $11,000 to improve the efficiency and flow of your addition. Since they design permanent features in each room, their services differ from interior decorators who focus solely on finishes and furniture.
Drywall and Paneling
Hanging drywall costs an average of $1,730. Instead of providing a total price, contractors may charge $1 to $3 per square foot for this service. If you want wood paneling instead, expect to pay $1 to $40 for each square foot. The difference comes down to the quality of the wood. Basic beadboard paneling is at the low end of the range, while maple, oak, and other pricey hardwoods are at the upper end.
Installing Doors and Windows
Installing windows costs $450 to $2,000 each for standard sizes. The total includes $300 to $1,200 per window plus $150 to $800 for labor. Contractors may charge $40 per hour to complete the install or quote a per-window rate. If you want one window each in the bedroom and bathroom, you will pay $900 to $4,000.
To install an interior door leading to the bedroom and another for the bathroom, expect to pay $300 to $1,600. Each interior door costs $50 to $500, depending on the material, size, and style. Labor is typically $100 to $300 per door. Exterior patio doors cost more at $1,200 to $10,000 installed.
Flooring
The price of flooring typically runs between $1,500 to $4,460. Depending on the flooring material you choose, expect to pay $3 to $22 per square foot. Vinyl and linoleum are the cheapest at $3 to $7 per square foot, while hardwood is the most expensive.
Building a Closet and Installing Organizers
If you will add a closet and install an organizer, you may pay about $3,695 total. Building the closet costs $2,015 on average. The price of the closet organizer typically ranges from $870 to $2,480.
Lighting
The price of a light fixture install is $150 to $825, depending on the style you choose. At $1,000 or more, chandeliers cost the most. Dome-shaped, flush-mount lights are the cheapest at $90 to $225.
Hanging a Mirror
To cover the cost of hanging a mirror, you will typically pay $160 to $465. The average price is $295, but the total can reach $800 for large wall mirror installs.
Installing Outlets
Installing outlets costs $75 to $485 each. In the bedroom, you only need two to three basic outlets for a total of $630 on average. In the bathroom, you must install GFCI-protected units, which could run $970 for two.
Installing Cable/Telephone Jacks and Wiring
Expect to pay $50 to $420 for cable and telephone jacks, including wiring. With this install, you will have convenient access to hookups for your TV and phone.
Built-In Bookshelves
If you want to cover the price of built-in bookcases, expect to pay $500 to $7,300 or $2,510 on average. Most projects fall in the $1,250 to $3,930 range unless you want them made from hardwoods or other pricey materials.
