A single room with your own bathroom (shower/toilet/basin), in a flat sharing a kitchen with other students. Beds may be single or small-double in size.
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. Here are a couple of reasons. A tub will take up too much space, and its large size will make this room feel much smaller.
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.
– Toilet size for comfortable use

What's the minimum size for a room with just a shower? The smallest tray size is around 700mm x 700mm, so your shower room will need to be at least just over 700mm wide. You need to allow room for the shower door to open, plus room for getting in and out. A workable minimum length would be around 1,500mm.
Typically, the smallest shower size is 32 inches wide by 32 inches deep. However, the International Residential Code (which regulates houses, duplexes, and townhouses) allows for showers as small as 30 inches x 30 inches. Measurements go up incrementally from there, usually to about 36 inches by 60 inches.
A length of between 1200 and 1500mm is usually sufficient. If you're creating a separate toilet room, you'll need to allow for more space. The standard door width in Australia is 820mm plus and architrave and wall space either side, so it's likely you'll want the room to be at least one metre wide.
A new bathroom could help your home increase in value, as well as providing a little peace and quiet for those more private moments. Typically, bathrooms have the potential to add between 4-5% onto your home's value. But this can go up or down, depending on how you execute your design and build.
