What does monobloc mean?
Monobloc denotes an object, especially a toilet, basin, chair, or similar fixture, made as one continuous piece rather than assembled from several separate components. In British English, “a monobloc” most often refers to a one-piece toilet whose bowl and cistern form a single moulded unit. The adjective is also used in product descriptions, as in “monobloc basin” or “monobloc chair.” The term comes from combining the prefix mono-, meaning “one,” with bloc, meaning “block.” Monobloc construction can make fixtures visually simple and reduce seams, joints, and potential leakage points, although accessibility and ease of repair may be affected by the integrated design. Although the word is especially associated with British plumbing and bathroom fittings, it is also understood in North American English. It should not be confused with monolithic, which describes something unified or indivisible more broadly rather than specifically identifying a one-piece manufactured object.

Where does monobloc come from?
The English word dates from the mid-20th century and comes from French monobloc, literally “single block.” It combines French bloc, meaning “block,” with the prefix mono-, meaning “one.” Its development reflects the growing use of moulded one-piece bathroom and household products.
How monobloc is actually used
In British English, monobloc is especially common as a noun for a one-piece toilet and, in product descriptions, for other moulded furniture or sanitaryware. It is descriptive and technical rather than strongly formal or informal.
Easily confused with monobloc
Monobloc describes an object made as one physical piece, whereas monolithic describes something that is unified, indivisible, or built from a single mass.
