Wondering, “how much does it cost to add a bathroom?”
You’re in the right place. We’ll show you all you need to know about pricing and factors affecting the cost.
With home improvements, it’s easy to go overboard and lose track of your budget. According to Home Advisor, the average national cost of renovating a bathroom is between $15,000 and $35,000.
But this cost increase significantly if you’re starting from scratch. It also largely depends on the size and finish quality. We’ve broken down the individual parts to help you better understand what it costs to add a bathroom.

How Much Does It Cost to Add a Bathroom?
Below, you’ll find a detailed breakdown of the various costs and factors that affect the total price of your bathroom addition.
Half Bath or Full Bath?
The first big decision you make is whether the new bathroom will be a half or a full. The main difference between the two is the amount of square footage and whether or not there is a shower or bathtub.
A bathtub or shower addition costs an average of $4,000. The average cost to add a basic shower stall in your bathroom is around $5,000, depending on the size and materials used.
A standard tub size costs around $4,200 to install, not including the price of the tub itself. While expensive, an extra bathroom can also increase you home’s value by about 10%, so it’s a worthwhile investment.
Not to mention that some home improvement are even tax-deductible.
Next, pick out and install a new toilet. The average cost to install a new toilet ranges between $300 and $400, including both labor and materials. Of course, this cost varies based on the type of toilet you choose.
Tiles and Flooring
The average cost to install tile bathroom flooring is around $10 to $15 per square foot. This changes for each project depending on how big or small the space is.
For example, installing tile in a shower stall ranges between $7 and $25 per square foot. You can reduce the cost by supplying your own tile.
Sink and Vanity
The bathroom addition cost also varies depending on the sink type and other plumbing fixtures you install. Still, the average comes to between $230 and $450, not including the cost of the bathroom vanity.
The cheapest sink is a pedestal sink since it has no counter. However, this addition still costs between $60 and $300 for the sink and installation.
Vanities come in all shapes, sizes, and price points, with prices ranging from $100 up to $1,500 for a simple 36×32 cabinet.
The same goes for storage and mirrors. If you hire a contractor to install your sink and vanity, expect to pay around $50 per hour on top of the material cost.
Plumbing and Electrical
The plumbing and electrical portion of your renovation or bathroom addition and the labor costs are the biggest expenses. To hire a licensed plumber or electrician, expect to pay between $45 and $200.
Of course, the bigger the project, the higher the cost. If you’re adding a bathroom, you’ll need new plumbing rough-ins and supply lines along with new outlets and light fixture boxes.
If the plumber has to cut into concrete (in basements), that’ll increase the cost even more. For a basement bathroom, I typically budget about $5,000 for new plumbing and $3,000 for electrical.
But again, that’s just my experience. Your cost will vary based on what floor the bathroom is being added to, the labor cost in your area, and overall bathroom size.
The average bathroom renovation costs between $15,000 and $35,000. And that’s just a renovation. If you’re adding a new bathroom, that cost range can easily double.
When I was managing properties, we’d typically expect a bathroom addition to cost around $15,000. But those finishes were rental grade, and had a simple tub/shower with a toilet and a cheap vanity.
Ultimately, the cost of your bathroom addition will vary based on the size, finishes selected, and whether or not you sub-contract the work or hire a contractor.
