A client from the tourism industry came to us with a concept for a mobile camping bathroom — a fully equipped sanitary module that could be placed on an individual pitch, giving each guest their own private bathroom without shared facilities.
Challenge
The client had a concept and a partially built mold. Completing the mold independently proved more difficult than expected — that’s when they came to us. The core requirement of the project was non-negotiable: the bathroom had to be produced as a single, monolithic piece. Traditional bathrooms assembled from separate parts tend to leak over time — the timber structure of a modular building moves, settles and changes dimensions with moisture and temperature, pulling joints and seals apart. The result is water ingress and costly repairs. A bathroom cast in one piece eliminates that problem at the source.
Key project requirements included
completing and commissioning the mold supplied by the client,
monolithic production — no seams, joints or potential leak points,
working with a large-format mold requiring appropriate production space and equipment,
repeatable quality and scalable production capacity,
durability in outdoor conditions and resistance to intensive use.
Our approach
We started by completing the client’s mold and producing the first units from it — giving us a physical reference for the finished product. From that, we built the actual production mold, which has since produced dozens of units. The mold looks straightforward, but its scale rules out workshop-level production — it requires a proper facility, equipment and experience with large composite molds. That was one of the key reasons the client chose to work with us.
The manufacturing process focused on
completion and verification of the client’s original mold,
prototype production from the temporary mold,
production mold build based on first-article reference,
repeatable series production launch,
adaptation support for modular construction applications.
Result
From an unfinished mold and an idea, a solution emerged that now works across two industries. In tourism: mobile bathroom units for camping sites — the monolithic structure means the whole unit can be cleaned with a pressure washer, with no risk of damaging joints or seals, because there are none. In modular construction: active implementation projects are underway where the one-piece FRP bathroom is installed as a complete, leak-proof module — with no risk of joint failure over years of use.
