We talked last weekend about the differences between a half-bath and a full-bath in the home bathroom. The total number of bathrooms in a home isn't exactly straightforward, and that information is necessary for decoding that terminology in real estate listings.

Even though we use fractions as shorthand for describing how many fixtures are in a bathroom, you can't simply add those fractions up to calculate the total number of bathrooms in a home. Two half-baths don't equal one full-bath. There are some tips for approaching real estate bathroom math.

## Calculating the number of bathrooms in a home

Real estate agents can vary in how they calculate the total number of bathroom in a home, but generally speaking, you start by adding the full bathroom together. The first number in the listing is usually the whole number.

It's time to factor in the 1/3-, 1/2-, and 1/3-baths, which can be tricky. Many homes have simple combinations of full- and half-baths. If there are two full bathrooms upstairs and a half-bath powder room downstairs, that would be a 2.5 bathroom home.

## Calculating more advanced bathroom math

Now that we have covered the basics, it is time to tackle more complicated bathroom math. A bathroom with a sink, toilet, and either a single shower stall, or a bathtub without a shower head is referred to as a bathroom with a sink, toilet, and either a single shower stall, or a bathtub without a shower head. It's almost always a shower stall in practice.

Some homes don't have a tub at all because of the countless home renovation projects that involved removing the original bathtub and replacing it with a larger shower. Real estate agents are likely to refer to it as a full bathroom.

Here is an example of how to calculate the total number of bathrooms when a quarter-bath is involved.

1 full bathroom with a sink, shower head, and tub, and 1/2 bathroom with a sink, shower head, and tub.

He adds the half bathroom and the full bathroom to get a total of 1.25 bathrooms.

Two half-baths don't make a full-bath according to his rule. It is important to keep in mind that you may encounter it in some real estate listings.
