Whatever the case – we’ve got the answers!

Today, we’re breaking down the average bathroom size and the common dimensions of bathroom fixtures, appliances, and more. So if you want your bathroom design to flow – keep on reading.

What Is the Average Bathroom Size?

First things first, what is the average bathroom size? The average bathroom size for a small home or an apartment is typically between 36–40 square feet (3.34–3.71 square meters). That general size includes both bathrooms with ¾ baths and full-size baths. That means that within space, you can have enough room for a shower, bath, toilet, and sink.

However, if you have a larger home, the average bathroom size you’ll come across is 40–100 square feet (3.71–9.29 square meters), depending on the property itself.

Types of Bathrooms and Their Average Sizes

The average size of a bathroom will typically depend on the space itself and the space you have on your property. If you’re not sure what the size of your bathroom should be, let’s take a closer look at some other spaces, how they work, and what they fit.

Average Master Bathroom Size

A master bathroom is the largest bathroom area in your home and it typically features a toilet, a sink, a shower system, and a hot and cold water supply. What’s more, most master baths also feature a bathtub, but some have a freestanding bath as a focal point for the space.

A small master bathroom is around 40 square feet, while the typical size for the space is 40–100 square feet. However, if your home allows for a larger bathroom, you can go up to 200 square feet (18 square meters) or beyond.

Full Bathroom Size

Similar to a master bathroom, a full-size one needs to have a shower or bathtub, a sink, and a toilet. It’s only considered a full bath if it contains these three items, and it’s typically 36–40 square feet. 

Average Size of a Bathroom With a Shower or ¾ Bath

Unlike a full bath, a ¾ bath only contains a toilet, a sink, and a shower, but not a bathtub. With varying sizes of showers, the average bathroom size is typically between 26–30 square feet. The most common dimensions for a ¾ bath are either 9×3 feet or 8×4 feet.

Bathroom With Walk-In-Shower Size

A bathroom with a walk-in shower has the same dimensions as a regular shower. The main difference is that the former has to be longer to support a larger shower compared to bathroom designs that only have to support a typical box shower.

If you only have space for a smaller walk-in shower, the average dimension to know is 36 square feet or 8×4 feet. However, one thing to keep in mind is that most walk-in showers need to be at least 4 yards (3.6 meters) in length to support the size of the shower itself. 

Size of Bathroom With No Shower or Half Bathroom

A bathroom with no shower, a powder room, or a half bathroom are all terms describing the same thing. A common layout for a smaller apartment would feature a powder room or half bathroom. It typically only has one sink and one toilet, with very little room for anything else. Generally, these types of bathrooms must be at least 15 square feet (1.4 square meters).

Typically, the largest half baths are only 26 square feet as those dimensions can accommodate a shower and other bathroom fixtures. If you’re going to go over those 26 square feet, it might be best to consider a different type of bathroom.

Handicapped Bathroom Size

For a bathroom to be considered handicapped accessible, it needs to be at least 15 square feet. Ideally, it should have a roll-in shower, which should be at least 5 feet wide and have no curb to accommodate a wheelchair.

Another important factor that makes a handicapped bathroom accessible is the entryway. It should have a width of at least 32 inches and it should not open inwards. Sometimes, a pocket door might be a good option to provide better accessibility.

Bathroom Features and Their Average Sizes

Now that you have a better grasp on bathroom sizes, let’s take a closer look at some other fixtures in your space, like a shower curtain, bathtub, door, and more.

Average Bathtub Size

The size of an average bathtub will vary based on dimensions, style, and more. The most common bathtub you’ll come across is an alcove bath with an overall size of 60–32 inches (152–81 centimetres).

If you’re looking for a freestanding bathtub, you should consider a clawfoot tub available in multiple styles. You can get different types of these tubs in cast iron, copper, porcelain, or acrylic. The average, medium size of a clawfoot tub is 54–32 inches, but it does come in bigger and smaller dimensions.

Typical Bathroom Sink Dimensions

If you have the space, a countertop could be a great focal point of your design and should be incorporated into your interior design plans. Unlike a toilet, for example, you can easily customize your countertop and the sink inside it. In fact, you can choose a wide array of materials and finishings that fit into your aesthetic.

That said, countertops follow a few general dimensions. Typically, the height should be between 34 and 26 inches in height. However, if the countertop features a sink, it should be at least 30 inches long or five feet if you have a double sink.

Average Shower Curtain Size

One thing that is not only useful for a bathroom but also aesthetically pleasing is a shower curtain. However, you should make sure you get the right size as buying the wrong dimensions can diminish its use or even introduce mildew to your home.

That said, the average shower curtain dimensions are 72–72 inches (182–182 centimetres). The length of a standard curtain should cover the tub and extend to the floor, giving you privacy and usability.
