Half Bath vs. Full Bath: Where’s the Value?


While perusing real estate listings on Zillow, Redfin, or Trulia, you’ve probably encountered terms like “half bath” and “full bath.”

Or maybe you’ve seen it expressed numerically, like “1.25 bathrooms” and “1.50 bathrooms.” Or even 3/4 bathroom.

What does it all mean? Do I need a calculator? I thought a bathroom was simply a bathroom, not a fraction thereof…

Real Estate Bathroom Definitions Matter!

While it can all get rather complicated, especially when different terminology is used for the exact same situation, real estate bathroom definitions matter.

They can dictate what a property is worth, how it is appraised, or what someone might be willing to pay.

So even if you don’t like math, it’s important to wrap your head around it so you know what you’re getting. Or what you’re offering to a prospective buyer.

So let’s break it down, once and for all, to determine what it means and assess the value each type of bathroom can bring to a home.

Let’s start at the top and work our way down. It’ll be easier to explain.

For the record, the most common arrangement is two full bathrooms per home. Something like 60-70% of new homes are built with two bathrooms.

The next most common setup is three bathrooms, followed by four and then finally one. In other words, it’s very rare for a new home to be built with just a single bathroom, for obvious reasons.

Full Bathroom (1 Bath)

A full bathroom contains four key items: a bathtub, a shower, a toilet, and a sink with running water.

So all four of these components must be in the room to designate it as a “full bathroom.”

Simple enough, right? It can’t really be disputed. All four or it’s not a full bath, regardless of what the listing says. And believe me, the listing will often deviate from the truth.

What’s surprising is how many bathrooms aren’t actually full bathrooms.

Three-Quarter Bathroom (3/4 Bath)

Then we have the “three-quarter bathroom,” which consists of three of the four aforementioned items.

So a three-quarter bathroom will typically have a stall shower (vertical upright), a toilet, and a sink. It’s missing the tub. The lack of a tub is probably the most common situation nowadays.

Some older homes may have a tub instead of a shower, but this setup is probably a lot less likely.

Confused yet?

Tip: Don’t get rid of a tub just because it’s not hip or aesthetically pleasing. It could affect the bathroom count and lower the value of your home (and cost you money to remove it!).

Although, I should mention that I’ve spoken with appraisers who don’t distinguish between 3/4 bath and full bath, so it may not even matter value-wise.

Half Bathroom (1/2 Bath)

If we remove both the shower and the tub, we end up with a “half bathroom.” This means in the case of the half bath there should be a room with a toilet and a sink (to wash your hands!).

Typically, half bathrooms are found on the ground floor of a house where there aren’t any bedrooms nearby. My brother-in-law actually has one in his basement.

It’s basically the guest bathroom, or the so-called “powder room” in many homes because you can’t do much else than apply makeup and do other unmentionable things.

Again, things can get murky here if the room only contains a shower and a sink, or a toilet and a shower. But the norm is the toilet/sink combo.

Quarter Bathroom (1/4 Bath)

You can hardly call this is a bathroom, can you? Or a room for that matter.

If anything, it’s really a teeny tiny room with just a toilet in it. It’s like an outhouse in the house. I guess you won’t be washing your hands after all…gross?

However, a “quarter bathroom” may also be a room with just a shower in it. Again, these are rare.

Assuming there is just a toilet, it might be smart to add a sink to give it a half bath distinction. It could boost the value of the underlying property. And lead to better hygiene…

Do the Bathroom Math

So bringing it all together, a house may be listed as 2.5 bath, 1.75 bath, or 1.5 bath, and so on.

If this is the case, we just need to break it down.

A 2.5 bath would mean two full bathrooms, and one half bathroom.

A 1.75 bath would mean one full bathroom, and one three-quarter bathroom.

A 1.5 bath would mean one full bathroom, and one half bathroom.

And a 2.25 bath would be a full bathroom, a three-quarter bathroom, and a half bathroom.

See how it gets complicated…it’s not algebra but it can get tricky after a while.

Tip: It’s important to make sure the numbers of bathrooms actually match the description of the home listing. Don’t just take their word for it because oversights and “mistakes” do happen.

What Value Does a Bathroom Add to a House?

Okay, enough talking about the bathrooms. Let’s talk about the money involved. Or rather, the value they can provide to a home.

While no two houses are the same, the National Association of Home Builders (NAHB) conducted a pretty robust study on this very issue back in 2006.

They noted that a half bathroom adds roughly 10.5% to a home’s value, while a full bathroom adds about 20%.

But they dug a bit deeper than that, breaking it down by bedroom-to-bathroom ratio.

For a home with an equal number of bedrooms and bathrooms, an additional half bath would increase the value by roughly 10%, and a full bath would add 19% more value.

And if the home has fewer bathrooms than bedrooms, the percentage gain can be even greater.

For example, consider a two-bedroom house with only one bathroom. If you add a half bathroom, it will increase the value by 11.5%.

Of course, the bathroom addition should make sense for the house layout to get maximum value.

And just to be clear, by “add,” it’s not to say building a bathroom addition yourself. You probably won’t get the value back. We’re simply comparing homes with different numbers and types of bathrooms.

In summary, be sure you recognize the value of a good bathroom folks!

  1. Most real estate agents call bathrooms “full” even when they’re not. Why is this not enforced!

  2. I’m looking at a house that won’t budge in price- says 1.5 bath- the .5 bath is a toilet installed in a closet off the main dining room for a prior handicapped person. (JUST A TOILET). Yes I think some realtors need to get a grip on their descriptions… some are wonderful and some are down right deceitful !!

  3. I have a quick question regarding these bathrooms that are a full bath.

    I have read above and it states that the full bath has all of the 4 amenities, i.e.: tub, shower (vertical), sink, and toilet.
    But, the 1/2 bath has only three of the these amenities.

    So, my question is:
    My master bedroom has a bathroom in it with just a Shower (Vertical Upright), 2 sinks, and toilet. Would that be considered as a Full Bath?

    Second, the bathroom on the first floor of my house has a Shower (Vertical Upright), 1 sink, and a toilet. Would that also be considered as a Full Bath?

    Last, the guest bathroom on the 2nd floor of my house has a Tub, 2 sinks, and a toilet. Would this be considered as a Full Bath?

    I just need some clarification because a few people has told us that the 2nd & 3rd bathrooms are only 1/2 bathrooms and that the master bathroom is a full bathroom because it’s in the master bedroom. Are all these correct? I’m totally confused. I need some clarification on this.

    Hope to hear a response soon.
    Thank You.

  4. Samm,

    None of those sound like full baths because none have BOTH a shower and a tub…as mentioned, you technically should have all four items in one bathroom to make it full. Whether it’s in a master or not shouldn’t matter to my knowledge. If there are only three items it’s technically 3/4 bath, though my guess is most people either call it 1/2 bath or round up to full bath. You don’t usually see real estate listings specify 3/4 bath.

  5. I currently own a 4 bedroom, 2.75 bath in an up and coming neighborhood. The .75 bath contains a stand up shower, double vanity sink and toilet. My husband and I are considering removing the shower as it is never used and instead, replacing it with a nice functional cabinet/storage closet within the bathroom. How much could this impact the value of the home, as we’d still retain the .5 bath with sink and toilet.

    Thanks for your help!

  6. Nasim,

    You’d wind up with a half bath, which would look like less house on paper (the listing) and that would lower the appraised value somewhat too. How much depends on comps in the area and what is typical for the area. More importantly, a prospective buyer of the home might be turned off even more emotionally and you could lose a sale as a result.

  7. We have an 1835 Colonial house with one full bath upstairs, and a half bath downstairs. The half bath has a toilet and vanity sink with a very narrow shower that only a small child can fit into. We want to take out the shower and replace it with a tall cabinet. Storage space is lacking, hence wanting to put in an extra tall cabinet. There is not enough space to put in a decent size shower that an adult can fit into even if we wanted to do that. We don’t have the ability to knock out any walls to accommodate a larger shower. Would the house still sell well with only 1 full bath and 1 half bath? The full bath has a toilet, vanity with a sink, tub and shower.
