¾ means 0.75, and why in the world would anyone call a bathroom 0.75? Well, the explanation is simple.
Since every component of a bathroom is equal to ¼ and a full bath is a whole one.
If you subtract one component from a full bath, leaving us with no choice, it will be called a ¾ or 0.75 baths.
The component, in this case, will be a shower or a bathtub.
Wait, I said OR not AND. The shower or the bathtub has to be present for a bathroom to qualify as a ¾ bath.
Should I add a shower or bathtub?
Typically, ¾ bathrooms have a stall shower and miss out on the bathtub.
If you are planning to build your house, it would be wise to add a stall shower instead of a bathtub in a ¾ bathroom because it is more aesthetically pleasing and takes up less space.
