5X8 bathroom is the master size bathroom. Commonly it consists of shower/tub, toilet, sink and one door placed in the corner.
Is a 5X8 bathroom too small? No, a 5×8 bathroom is the minimal size for a full bathroom, which includes a shower and a bathtub. Although the space might seem cramped, 40 square feet is still a good size for a bathroom.
While 5 by 8 feet may seem like a small size for a bathroom, it's actually the most common floor plan that can still encompass a sink, a shower and tub, and, of course, a toilet. That said, the limited square footage does mean that those designing such a space from scratch may struggle with layout.
However, the space is large enough to fit a shower/bathtub, a sink, a toilet, and a small vanity, although the space will feel fairly cramped. The advantage of a 5×7 bathroom is that you can enjoy the functionality of a larger bathroom at a reduced price which can make up for the lack of space.
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.
Typical Small Bathroom Sizes
For a powder or half bathroom, 18-20 sq ft (about 1.7 - 1.9 m2) is a good, average size. For a ¾ bath, 40 square feet is a good size (about 3.7 m2). A small full bathroom, with a sink, toilet, and combined shower/bathtub is often 40-45 square feet (about 4 - 4.5 m2).
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.
A 5×7 bathroom is often thought of as the minimum size for a bathroom. It's just big enough to fit a toilet, shower, and vanity sink. However, maneuverability will be extremely limited and a bathroom of this size isn't very accessible to those with mobility issues.
The dimensions are 6' X 6' or 36 square feet.
Another common small-size bathroom is the 6X6. Although this meets the minimum requirement of a full bath, it's a more spacious approach to make it a ¾ bath.
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.
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).
Technically a full bath is supposed to have a tub, toilet and sink, while a half bath only has a toilet and sink. “Then what does 1.5 baths mean?” One point five baths also means that the house has one full bathroom and one half-bathroom.
How Big Is A Tiny House Bathroom? A tiny house bathroom usually ranges 25 square feet to 50 square feet. My rule of thumb is it should be 25% of your ground floor, assuming your bed is in a loft.
At minimum, a full bath requires at least 40 square feet with all the additional elements accounted for. Typical building code requires at least 32 square feet for a shower, so the additional 8 feet account for the addition of the bathtub.
Clearance: At least 24" of space is needed in front of a shower or tub entry. Leave at least 15" of space between the shower and toilet or other obstacle.
A half bath needn't be large. You will have enough space if you can find a spot in your house that's about 3 to 4 feet wide and 6 to 8 feet long. If it's any smaller, it will be uncomfortable for people to access.
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".
The average ratio for most homeowners is that there should be at least two bathrooms for every three bedrooms. For instance, if you have a three-bedroom house, it is most likely that there will be the main bathroom for adults, and a family bathroom for children and other members of the family.
As you can see in the above example, 5x7 and 8x10 prints (often referred to as 'gift prints') are best for displaying on a table or desk. They are typically considered too small for a wall print. For your wall, go big or go home!
Half-Bathroom/Powder Room
These bathrooms have only a toilet and sink and are commonly used by guests due to their location beside hosting areas such as the living room, dining room, and kitchen. The average size of a half-bathroom or powder room is 20 square feet, but older homes have some as small as 11 square feet.
Powder rooms or guest bathrooms are also known as a half bath. It only has one sink and one toilet. These are often small spaces of about 15 to 20 square feet. It can be larger, of course, but after a certain point, you may just be wasting space.
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.
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.
A 2.5 bath would mean two full bathrooms, and one half bathroom.
