noun
A katakana noun for a lavatory or toilet facility. Less everyday than トイレ, and often feels like a label or technical/service-industry term, such as on aircraft or in facility descriptions.
飛行機のラバトリーは機内の後方にあります。
The lavatory on the plane is at the rear of the cabin.
ラバトリーを清
The lavatory is being cleaned.
