What is a bathroom group?

A bathroom group refers specifically to a set of fixtures that are typically found in a bathroom, including at least a water closet (toilet) and a lavatory (sink). This term is used in plumbing to categorize the basic components necessary for a functional bathroom area.

The inclusion of both essential fixtures reflects standard building practices and plumbing codes, which often require these elements to work in concert. This configuration supports the proper drainage and plumbing layout in residential or commercial plumbing designs.

In contrast, while a grouping of fixtures located on different levels or a single plumbing fixture could be relevant in certain contexts, they do not define a "bathroom group." Similarly, the concept of a conjoined drainage system does not capture the specific function and layout typically associated with a bathroom grouping, as it relates more to overall plumbing infrastructure rather than the specific arrangements of bathroom fixtures.
