Has the bathroom in your house grown too old? If you’re not the only person utilizing your tiny sink-toilet-tub-shower combination, it might not be cutting it anymore. The obvious solution to this issue is to add a second bathroom to your house, but the cost of this bathroom, like many others, can be a mystery. So, it’s time to find out how much it will cost to add a bathroom to your house, basement, and garage.
A bathroom addition to your house may be an expensive investment, but you’ll be rewarded with a more useful living area and a higher potential market value. Additionally, installing a bathroom might not be as expensive as you anticipated. Keep reading to find out about a few tips that can help you save some money.
How Much Does it Cost to Add a Bathroom to a House?
The average cost to add a bathroom to your house is $15,000, however, this cost can vary significantly based on how much space you need and what features you choose. The typical range is therefore $5,000 to $35,000
But only if you build the bathroom in an already-existing space. The price range increases significantly—on average from $20,000 to $50,000—if it is new construction.
Naturally, the top limit isn’t limited to that. The price range could be closer to $75,000 to $90,000 if you want a high-end bathroom addition with a whirlpool hot tub to relax in after a long day at work and other high-end features.
What Are Included in These Costs?
While the price to add a bathroom to your house, basement, or garage may appear exorbitant, it covers several expenses, such as flooring, plumbing, hardware, permits, and installation, in addition to your bathroom’s essentials. If you’re building a new addition, you’ll also need to pay for those extra costs, such as framing, insulation, and drywall, even if you’re just adding a bathroom to an existing area. It comes as no surprise that the cost of a bathroom expansion starts in the hundreds of dollars given all these expenses.
However, sourcing less expensive materials are one of the simplest methods to reduce expenses without sacrificing quality. This can entail choosing a prefabricated bathtub or shower over an expensive tile surround, purchasing a vanity from IKEA, or renovating an existing one as opposed to having one specially built. Additionally, you can attempt doing a few tasks on your own, such as installing hardware, painting, or—if you’re feeling daring—tiling.
Bathroom Addition to an Existing Space
It will be much less expensive to add a bathroom to an existing one than to build one from scratch. According to HomeAdvisor, a bathroom addition will cost the typical homeowner roughly $15,000 in costs.
To break it down even further, bathroom upgrades to an existing area might cost between $125 and $250 per square foot. Want to add a bathroom while saving even more money? Remodeling more wisely: You can save money on plumbing and draining expenses if you convert a room that already contains the plumbing you’ll need, like your laundry room. For the same reasons, it can also be less expensive to build new bathrooms directly above or below those that already exist.
Bathroom additions upstairs versus downstairs
Bathrooms upstairs provide convenience and solitude, especially if they are en suite. However, the cost of that luxury might be high. Expect to pay more for that bathroom expansion if your upper floors don’t already have plumbing or drain lines. According to HomeAdvisor, the price of second-floor bathrooms can cost from $8,000 to $35,000.
However, since you’ll generally be nearer to the plumbing, having downstairs bathrooms could allow you to save some money. Consider installing a half bath, which only has a sink and a toilet, rather than a full bath if you only require the bathroom for the occasional visitor or dinner party. Half baths are an excellent method to save cost and room while still offering essential functionality.
How Much Does It Cost to Add a Bathroom Myself?
To guarantee they adhere to safety and code requirements, it is always preferable to leave electrical and plumbing work to the professionals. In addition, if a contractor is required to correct any DIY errors, it could end up costing you even more money in the long run. However, if you do have this experience, you can hire contractors for a lot less money—possibly more than half of the project’s overall cost. The majority of the final costs will be spent on vanities, drywall, and tile.
For instance, if installing a bathroom costs $45,000 total (labor, materials, and permits), you can decide to handle all of the plumbing, electrical, and installation work yourself. You could save around $25,000 by building it yourself because the job would cost about $20,000 in materials alone.
Bathroom Addition Costs by Location
Location plays a significant role in determining how much it will cost to add a bathroom to your house, basement, or garage. The average cost to add a bathroom in San Francisco is $67,378. This is higher than the average price in Atlanta, which is $46,937. Similar to this, the average cost of an addition to a bathroom in the mid-Atlantic region is $51,653, whereas the average cost is $44,443 in Oklahoma.
Do not worry if you are in an HCOL area. Choosing installers and contractors who have a reputation for providing excellent service at a reasonable price will help you keep costs down. You can also ask your local friends and family for recommendations.
How Much Does It Cost to Add a Bathroom In The Basement?
A 6×8 powder room with 8-foot high ceilings will cost $15,200 to add to your home’s basement. Installing a new sewage-ejector system that takes your waste up and out of the basement area costs an additional $720 to $1,350 in plumbing labor. The majority of basement bathroom fixtures cost about the same as those in other bathrooms.
How Much Does It Cost to Add a Bathroom to a Garage?
It is possible to add a bathroom when you are building a garage, but you can also rebuild an existing garage to add anything from a compact bathroom to a master suite. Typically, it will cost between $8,000 and $25,000 to add a bathroom to a house garage. Depending on where your plumbing and electricity come from, garages typically have more design and space options. Since electricity and plumbing frequently enter the garage, it may be more cost-effective to add a builder-grade room rather than a fancy one.
The price range increases if you intend to convert your garage into a larger master suite by enlarging a bedroom. It costs $15,000 to $50,000 in total. Any wall that surrounds a garage is a load-bearing wall, so you must add a header beam to help support the weight of a door when you install one. A wide range of finishing prices are also offered.
What Elements Impact the Cost to Add a Bathroom to Your House, Basement, and Garage?
The cost to add a bathroom to your house, basement, or garage varies greatly and is based on a variety of diverse criteria.
The entire cost of your project will be significantly influenced by the bathroom’s square footage. The cost will increase with the size of the space. For an average bathroom addition, the cost per square foot is from $200 to $300, and for a luxury addition, it ranges from $450 to $600.
You will need to spend more if you want your bathroom to have upscale features. For instance, a jetted bathtub or whirlpool can cost around $10,000. The price of vanities can cost from $500 to $4,000.
Addition or Existing Space
Because you don’t have to construct an actual structure as you would with an extension, it is far more economical to create the new bathroom in an area that already exists, such as a former bedroom or the basement. Remember that you might need to budget for the cost of installing rough plumbing for a bathroom in an existing area.

Depending on a wide range of variables, the average cost to add a bathroom to your house, basement, or garage varies.
