Want to see composting toilets, greywater systems, and alternative wastewater solutions in person? Visit the WCTNZ® showroom and talk through your project with our team.
Our Auckland hub gives customers a practical place to view systems, understand how they work, and discuss the best pathway for their home, bach, tiny house, commercial site, public facility, or off-grid project.

A showroom visit can make the decision clearer. Composting toilets and greywater systems are easier to understand when you can see the product, talk through the installation pathway, and ask practical questions before committing to a system.
The showroom is useful if you are trying to understand the differences between composting toilet types, greywater pathways, ventilation requirements, chamber access, capacity, installation planning, or the wider package your project may need.
Some customers arrive knowing exactly what they want. Others are still working out whether they need a self-contained composting toilet, split system, greywater setup, pump station, toilet building, or a more complete system package.
Visits are best during showroom hours. Booking ahead is recommended, especially if you would like to discuss a specific project or product pathway.

If you are not in Auckland, WCTNZ® can arrange a virtual showroom discussion by video call. This can be useful if you want to talk through product options, site details, installation considerations, or the likely system pathway for your project before ordering.
Helpful details to send before a virtual meeting: project type, location, expected use, photos or plans if available, stage of the project, known site constraints, and whether the enquiry is for a composting toilet, greywater system, toilet building, pump station, or wider package.
Tell us what you are planning and what you would like to see or discuss. We can help you prepare for the visit and guide you toward the most useful next step.
