The Importance of Adding a Bathroom

Additions to your house can improve the comfort level of your home and increase the value when it comes time to sell. Depending on your situation, you may be required to make renovations to ensure your house is up to code.

Although prices are going to vary wildly depending on your specific location, the size of the bath, the quality of the new renovation, etc., adding a bathroom can increase the value of your home by 10%–25%. You can expect to recoup about 50%–70% of the renovation’s cost in increased home value when you sell.

Families are not always interested in homes with only one bath, so increasing the number to at least two will increase your house’s appeal.

How Much Would a New Bathroom Cost?

If you’re converting an existing space, expect to spend anywhere from $2,500–$12,500, with the average being $7,600. Some estimate the average closer to $15,000. If you’re creating an entirely new addition to the house, estimates range from $18,000–$50,000, with an average of $22,000—$30,000 by some sources. If you’re going for a real luxury experience, it can run upwards of $100,000. Of course, these numbers will depend on several factors:

  • Whether it’s a half-, three-quarters-, or full-bath
  • Overall size of the addition and the number of changes to the house
  • Whether it’s close to existing plumbing or if new plumbing are needed
  • If the house is old and the electrical system needs to be updated
  • Where the renovation is located—upstairs, downstairs, master bedroom addition, etc.
  • Whether you do it yourself or work with a contractor

Additional Costs To Anticipate

If you’re hiring a contractor, they’ll have fees you’ll need to factor in. Labor for plumbers and Electricians can run $85-$120/hr. This makes the cost of labor one of the most significant factors impacting the price tag of the project—about 50%-60% of your expenses will be labor alone. This is why many people think about taking the DIY route, as it can save you a significant amount of money, assuming you know what you’re doing.

An easily overlooked but necessary expense is acquiring permits. It would be a good idea to at least consult with an expert on your local permitting requirements because they’re different for every neighborhood.,

Counties and cities often require permits for both external additions and internal renovations. Any time new plumbing or new wiring is being installed, you’ll likely need a permit. T Some areas may also have regulations mandating minimum square footage or quantity of bathrooms as well. HOAs will also get in on the fun with their own set of codes. The permits themselves can cost anywhere from $200-$500, but the various code requirements will have a considerable impact on your overall cost.
