Prefabricated bathrooms in innovative leightweight design
Leightweight and robust bathrooms
Green Box bathrooms are built in an innovative lightweight design with high strength and stability. Each bathroom weighs only 325 kg/m2 as a standard.
The walls and ceilings are made of a galvanised steel structure, which ensures that the bathrooms can be stored in the open shell structure and withstand the high humidity to which they are most often exposed until the shell structure has been closed off.
The floor structure consists of a steel frame and a concrete cast floor, which is cast on a laser-cut template. This procedure ensures that we can comply with tolerances of +/- 1 mm and always achieve the correct slope towards the drain.
We only use full-format fibre gypsum boards. This means one wall = one board. In other words, no joints which need to be glued or filled.
Green Box bathrooms are well suited for modular construction, CLT and other types of wooden construction as well as in concrete construction. In fact, the light bathrooms here provide good opportunities for slimming down the whole structure and floor separations. This is good for both the economy and the environmental footprint of any building project.
Optimisation via digitalisation and automation
The steel structures for all Green Box bathrooms are punched and bent in a fully automated plant.
Our line production optimises the work process, as the bathroom comes to the employee – and not the other way around – unlike in conventional building projects.
At Green Box, we have always invested heavily in digitalisation and automation of as many parts of the overall production process as possible. We have already come a really long way, but we are continuously working to optimise our process even further, including through robotics.
This focus on innovation is what allows us to be at the forefront of the development and production of the market’s preferred prefabricated bathrooms.
Floor construction
that reduces building height
Prefabricated bathrooms from Green Box have a cast concrete floor that ensures a low installation height – as low as 95 mm.
Because our bathrooms are built around a steel structure, we can significantly reduce the concrete thickness of the floor.
The low installation height makes it possible to reduce floor separation, which means that the total building height is also reduced.
As an added bonus, you will therefore be able to reduce both the price and quantity of building materials in your construction project. This is good for both the economy and the environmental footprint of any building project.
Membranes
Effective wet room protection
We waterproof the floor in our Green Box bathrooms with high-quality sheet membranes. This allows us to guarantee the correct membrane thickness throughout the bathroom.
Tiled walls are also waterproofed with a high-quality sheet membrane so that moisture does not penetrate the structure. The glue on the sheet membrane also ensures that there is no risk of loose tiles.
Ceiling types
Ceilings of steel or plaster
Choose between two ceiling types for your Green Box bathrooms:
Painted steel ceilings are often used in buildings with high frequency of use and wear – for example in student housing units, where there is a special need for solutions with minimal maintenance.
Plaster ceilings are made with the same steel cassettes on which large-format Fermacell plaster is fully glued. This ceiling type is often used in hotels and residential buildings.
When installing spotlights in the ceiling, we use safety boxes that provide a 100% tight ceiling.
Fire and sound requirements
Bathrooms as apartment partitions
Green Box bathrooms are tested and third-party approved by the Danish Institute of Fire (DBI) as apartment partitions both in accordance with fire requirements and sound requirements of 55 dB.
When two bathrooms are placed next to each other, a fire resistance of EI60 is achieved.
We are happy to send you relevant documentation on request.
Plumbing installations
How we perform plumbing installations
Plumbing installations in Green Box bathrooms are performed in PEX hoses, which are insulated up to junction boxes. All fittings are made of gunmetal.
All installations are pressure tested by means of an electronic pressure testing facility. The results are specified in a quality report, which you can access via a QR code for the individual bathroom.
Drainage installations can be led to the shaft in the walls, thus achieving a low installation height.
Packaging
with great flexibility
Prefabricated bathrooms are often left for many months in the open shell structure, where they risk being exposed to wind and weather. Due to their closed steel structure, however, Green Box bathrooms are protected against weather and penetration of water into the structure.
Before delivery, we close the entrance to our bathrooms with a hinged wooden board, after which the entire bathroom is packaged in strong shrink film. The shrink film is UV resistant, and the bathrooms can therefore be left outside in all kinds of weather for up to six months.
We store your bathrooms in our own large storage facility until the requested delivery date. After delivery, you do not necessarily have to install your bathrooms right away; you can wait until the shell structure is ready. This provides great flexibility and the possibility of adapting the time of assembly in the event of a slip in the schedule for your construction project.
