A five-piece bathroom (or five-piece bath) is one with five plumbing fixtures, including a sink, toilet, and three more fixtures. A two-piece bathroom has only two fixtures: a toilet and a sink.
The term "five-piece bathroom" may also be used to describe a room that contains all of these fixtures. However, in this case, the word "bathroom" would be in italics, indicating that it is not actually a bathing area but rather a place where you can wash yourself. Such rooms are commonly found in hotels and other lodging facilities where people can take a shower or use one of many other amenities available.
Five-piece bathrooms are most common in homes built before 1990, when water efficiency became important to home buyers. These days, homes tend to be built with either four-piece or six-piece bathrooms. The former contain only a single pair of matching fixtures while the latter are usually found in newer houses. There are also eight-piece and nine-piece baths, but they are becoming increasingly rare.
There are several reasons why most homes today are being constructed with four-piece or six-piece bathrooms instead of the traditional five-piece version.
A three-piece bathroom (3-piece bath) is a restroom that has three plumbing fixtures: a sink, a toilet, and one more fixture. This type of bathroom is most common in North America.
The two-piece bathroom (2-piece bath) has only two plumbing fixtures: a toilet and a shower or tub. These bathrooms are common in Europe and other parts of the world.
In some countries, such as Japan, there are regulations about the number of toilets that can be placed into a bathroom. The number allowed varies by the size of the room but usually isn't more than three. These regulations aim to ensure that each person has a private place to go when they need to use the bathroom.
There are also regulations about the distance between toilets. These distances vary but generally speaking, if you stand next to a toilet when it is being used, then you should be able to reach over its tank without touching the water.
If there are no such regulations in your country then a three-piece bathroom could be easier to design and build. It would allow for more space inside the bathroom and could even be considered an advantage in some cases!
The most frequent type of complete bathroom is a four-piece bathroom. A four-piece bath's four fittings might potentially be any of the following: Toilet, sink, shower, and bathtub (most common by far) Sinks, toilets, and bathtubs, oh my! Sink, sink, toilet, and shower. Or maybe just sink, toilet, and shower.
Four-piece bathrooms are most commonly found in homes built before 1990. They're convenient because they combine all the necessary plumbing fixtures into one easy to install package. Also called multi-use rooms by some builders.
Five-piece bathrooms are also common but they usually include a second shower fixture. This is useful if you want to have a shower that's not connected to the main water line. Soap nuts and other people who can't stand the feeling of having someone else's hair in their showers will love five-piece bathrooms. There are several different ways to layout these rooms so they can be used as either a five- or four-piece bathroom depending on your preference.
Six-piece bathrooms contain two separate shower fixtures one next to each other. Soap nuts and other people who can't stand the feeling of having someone else's hair in their showers will love six-piece bathrooms.
