Prefab bath
another term for what we call prefabricated bathrooms
In the construction industry, the term prefab bath is often used to describe what we at Green Box call a prefabricated bathroom.
At Green Box, you get fully finished, Danish-produced prefabricated bathrooms, made of high-quality materials, factory tested and delivered to the construction site, ready to be connected to all technical installations. An efficient and time-saving solution that optimises the construction process and which can shorten construction time.
The story from prefab bath to prefabricated bathrooms
The term prefab bath is short for prefabricated bathroom. Prefab baths have gained ground in the construction industry concurrently with an increasing demand for time-saving, efficient and uniform construction of wet rooms. Green Box became part of this development when the company began its journey in 2014 based on a need in the market for prefabricated bathrooms with low installation height and low weight.
Over time, the prefab bath concept has developed through more specific terms such as shower pod and bathroom pod. Thanks to good operational experiences, prefabricated bathrooms have become a regular part of new builds and renovation projects.
Today, prefabricated bathrooms are increasingly often chosen over bathrooms produced on site. The ready-to-install bathrooms can help shorten construction time and ensure consistently high quality. The production of prefabricated bathrooms takes place under controlled conditions with less waste and can therefore also help reduce resource consumption.
