A full bathroom is made up of four parts: a sink, a shower, a bathtub, and a toilet. Anything less than that, and you can't officially consider it a full bath. Therefore, a bathroom with a sink, toilet, and shower is considered a three-quarter bath. A bathroom with just a sink and a toilet is a half-bath.
Three-Quarter Bath
A three-quarter bathroom will have three of the four key components. Most commonly, these rooms will include a toilet, sink, and a shower stall without a bathtub (or in some cases, a bathtub without a shower).
A full bathroom consists of four parts: a sink, shower, bathtub and toilet. If it's less than that, it's not considered a proper full bath.
Many ¾ bathroom floor plans come in at an average size of 40 sq ft (just under 4 m2), although they can be smaller or larger. A standard ¾ bath floor plan in that size range uses a rectangle shape with 5 ft by 8 ft (about 1.5 m x 2.4 m) wall lengths.
Common Dimensions for a Full Bath
While 40 square feet (8×5) is the minimum size for a full bathroom, it is fairly small and most layouts make it seem cramped. The average size for a full bathroom is around 60 square feet (6×10), which is considered the most efficient size for a bathroom.
Structural Considerations and Requirements
A full bath requires a minimum of 36 to 40 sq. ft. The finished room must measure at least 5 ft. in one direction to accommodate a tub.
But does it come at a price? Typically, a bathroom must have a toilet, sink, and tub to be considered a full bath. A bath with a toilet, sink, and shower, but no tub, would be considered a three-quarter bath. The master bath can be a major selling point or it can be a deal breaker.
The short and simple answer to whether a walk-in shower is considered a full bath is “no”. It is not. As mentioned previously, a bathroom is considered a full bath only when it has all the 4 components of a sink, toilet, shower and bathtub. If it doesn't include all 4 features, then it doesn't count.
Most people seem to like having a master bathroom with dimensions of 150-by-160 square feet. It's enough space for two people to move around without having to squeeze past each other plus all the other amenities. People who want smaller master baths tend to go between 60 and 70 square feet.
These types of bathrooms do exist, and they are referred to as quarter-bathrooms. These quarter-bathrooms are quite rare simply due to the fact that they contain only one of the 4 main elements of a bathroom. The most commonly seen are those that contain a shower and are typically found at beaches or pools.
Fortunately, many homes have relatively simple combinations of full- and half-baths. So, for example, if there are two full bathrooms upstairs and a half-bath powder room downstairs, that would be a 2.5-bathroom home— even though there are three rooms in the house that most people would identify as bathrooms.
A half-bath, also known as a powder room or guest bath, has only two of the four main bathroom components—typically a toilet and sink.
Named after the children in the famous nursery rhyme, a Jack and Jill bathroom is a full-sized bathroom that is sandwiched between two bedrooms and is accessible by both bedrooms. This type of bathroom has at least two doors, like an ensuite bathroom but for two bedrooms rather than just one.
A . 75 or ¾ bath is a bathroom that contains one sink, one toilet and a shower or a bath. Traditionally, a full bath contains at least one sink, one toilet, a shower and a bath, so a . 75 bathroom only has either a shower or a bath.
Half Bathroom
Half-bathrooms have a toilet and a sink. Half-bathrooms are called powder rooms or guest bathrooms as often as they are called half bathrooms.
When it comes to choosing between a walk-in shower or bathtub, there is no right or wrong answer. It all depends on your needs, preferences, and budget. If you have a small bathroom, a shower might be the best option. If you want a luxurious bathing experience, a walk-in tub might be the way to go.
What is a quarter bath? These are most commonly found in older, smaller homes, usually in the basement, especially an unfinished, and consist of just a toilet or shower stall. Sometimes, they aren't even partitioned off into their own separate room.
A Jack and Jill Bathroom is a bathroom that has two doors and is usually accessible from two bedrooms.
“There absolutely has to be at least one bathtub in any condo or home. When you sell, you're also selling a lifestyle and having no tub will hinder a sale to most buyers,” she says.
A 2.5 bath would mean two full bathrooms, and one half bathroom.
Most codes require at least 15 inches (measured from the center of the toilet) from any side wall or obstruction and not closer than 30 inches center to center to any other sanitary fixture. (The NKBA actually recommends 32 inches.)
What is a four-piece, otherwise known as a full bathroom? A four-piece bathroom suite contains a sink, a bathtub, a shower and a toilet. Usually, the tub and the shower are placed close to each other on the other side of the room as the door, with the vanity in the middle.
The average walk-in shower in the U.S. measures 60" x 30", though size options can vary widely, typically up to 60" x 42" for a rectangular shower and 42" x 42" for a square one. For smaller bathrooms, most experts recommend a shower enclosure no smaller than 36" x 36".
