- "Makes it possible to bring the spring water into Arls. Peter asked me to make this. I'll need lots of them, but now we'll have have a hot spring in Arls!"
- — Atelier Meruru description
Pipes are a synthesized item in Atelier Meruru: The Apprentice of Arland.
The pipes are used to build the hot spring near Mt. Velus. Multiple pipes are needed to bring hot water from Arls to the hot springs.
The hot springs can be built after Airshatter is defeated at Mt. Velus. Peter will approach Meruru with his newest "get rich quick" scheme. The hot springs need to be built for the "Girls Bath" cut scene and the "Boy's Bath" ending.
