Car park toilet facilities

Our public toilet systems for unmanaged car parks on motorways and busy trunk roads, also known as PWC (parking WC), are free-standing buildings. Modules prefabricated in the factory are put together and installed on site. The fittings and design are based on customer requirements.

With the vandalism-resistant construction, we can guarantee long-term suitability and service life for these car park toilets. Our toilet systems offer everything a state-of-the-art, practical toilet can be. All media connections (water, waste water, electricity) are typically established on site. Waste water processing using membrane filter technology is also an option.

Concept development

PWC systems are often built to the same design for years. The design, technology and fittings have oven been proven in everyday practice. But moving with the times and being open to innovations is also recommended.

Tread new paths with us, whether towards design, functionality or materials. Capitalise on our decades of experience in the construction, operation (maintenance, repairs, refurbishment) of car park toilet systems.

Sustainable WC facilities

From planning to upcycling

Our WC facilities are characterised above all by the fact that they last up to 45 years. Such durability is achieved through the use of concrete for load-bearing structures; concrete allows service lives to be extended by up to three times over other building materials. We also score sustainability points when it comes to running the WC facilities: Detergents that are 100% biodegradable, the reduction of plastic waste by up to 70% thanks to the use of detergent concentrates as well as special coatings, such as our ‘easy-to-clean coating’, to name but a few of our innovations.


The HERING Group is an EMAS-certified company and attaches great importance to ecological construction methods and services as well as the appropriate use of materials. HERING Sanikonzept GmbH convinces with its concept for WC upcycling in the field of public conveniences: The company takes back and refurbishes old, outdated public WC facilities as prefabricated cells. Its self-sufficient toilets for low user frequencies also convince with their ecological features as they are operated without electricity, water and waste water connections.
