This is especially true if an additional bathroom helps relieve congestion at hectic times, or if it provides much-needed convenience for guests — no small considerations.
As an investment, however, a new bathroom should be carefully considered. The cost of a midrange bathroom addition is about $38,186, but the return on that investment averages a modest 60.1%, according to Remodeling Magazine’s annual Cost vs. Value Report.
Nevertheless, national averages may not be a reliable predictor of value in your particular neighborhood. Before committing to a bathroom addition, call in a real estate agent or professional appraiser to evaluate whether an additional bathroom makes sense in your situation. Buyers tend to prefer houses where the number of bathrooms equals the number of bedrooms, according to NAHB.
NAHB data also suggests that an additional half bath may increases a home’s total value by about 10%, while an additional full bath increases the value by 20%. However, that doesn’t mean you’ll recoup the full value of your remodeling investment — on average, you’ll spend almost twice what you recoup.
