    Customer Testimonials

    "The Little River Campground, Banks Peninsula has been using the CM40 for over 10 years with no issues. We investigated many composting toilet systems and decided the Clivus Multrum CM40 model was the best by far - the simplest and most affordable for the amount of daily visits. We even get compliments as to how good they are!

    Our system has 4 pedestals that collect waste into one large composting chamber that is emptied once a year. This compost is then stored in a secure area, well away from the campground to decompose into useful compost that is spread around fruit trees in our orchard.

    Over summer we can have over 100 guests staying per night. As a seasonal campground we have 5 months of little use, which gives the waste time to compost and the removal is not too unpleasant.
    The amount of water we have saved is 100,000s of litres.

    The pedestals are robust and easy to clean. We designed the toilet block to sit on the edge of a bank, with easy wheelchair access at ground level. We added a separate urinal for males, which is diverted from the main chamber.

    We can recommend the team at WCTNZ to give you good advice and service."

    clivus multrum cm8 composting toilet at huia road horse club

    "We got a Clivus Multrum CM8 composting toilet because it fits our ecological ethos. We do a lot of environmental initiatives and a composting toilet just seemed logical.

    We are effectively off-grid with no power. The sewer wasn't in the right places for us and we weren't allowed to do a longdrop as it can leach into the environment. So, the Waitakere Ranges Local Board consented the composting toilet and gave us the funding for it as an eco-friendly solution. The toilet fan is driven by solar and we have a wind-driven vent as a redundancy measure.

    We've had it for over 3 years and it hasn't given us any grief. We've had no complaints from visitors and overall people have been most impressed! People possibly expect it to be like a smelly longdrop, but its a whole lot more pleasant. 

    The toilet gets continuous part-time use with some peak loading on event days - we were worried about overuse but this hasn't happened.

    Everybody pitches in with maintenance, which is easy and not distressing. It is actually impressive how little time is spent on maintenance - the compost is raked once a month and after 3 years we still haven't had to empty the toilet!

    When we do empty it eventually, we are planning to bury the compost in flower and bush plant beds.

    Overall, we are very satisfied with the Clivus Multrum CM8 and Dylan from WCTNZ was always helpful when we were enquiring about it."

    "I was having fly and smell issues with my batch compost system, which had been supplied by another company and they were being incredibly unhelpful (I regret dealing with them).

    Dylan at WCTNZ was able to educate me and gave me a few solutions to try even though the system isn’t one that WCTNZ supplied. I ended up buying a second fan which has solved the problem.

    I HIGHLY recommend Dylan and WCTNZ, he is filled with knowledge, friendly and helpful. I will be purchasing through this company again and definitely will be recommending to others."

    "We are off-grid and live in a house truck. We wanted a cost effective system that was environment friendly with as lower maintenance as possible and was mobile/relocatable. We have a Clivus Multrum CM HP.
    Installation instructions were well detailed and very practical. The installation proved to be a fun activity for a recently retired couple. The final result is a beautiful toilet to use inside and we enjoy our flushless experience.

    The toilet is easy to keep clean and absolutely no smells when making a deposit.

    Teething Problems with occasional odours:

    • Needing to install an additional fan required for the southerly wind. All other wind directions are fine which is great as we can have strong winds!
    • Learning to use the stirrer to it's potential.
    • Finding water in the flexi hose part of the air vent system therefore blocking the air flow.
    • Finding straw in the air vent above the fan, another air flow restriction.

    We decided to buy from WCTNZ because they had the best information and their video tutorial show you how their system works. They were very helpful and patient towards a prospective customer, sorting out the best option for us, then checking our order to ensure we received what we were expecting to receive.

    We phoned two times during our installation and their genuine reply always sorted out our difficultly.
    Our communication with the team at WCTNZ has always had a quick response and their ability to install confidence is fantastic!

    We do recommend WCTNZ for all the above and to promote the fact that we can all personally take responsibility for the care of the planet.

    Thanks again team for your patience."

    "I've had my Clivus Multrum composting toilet system for close on 10 years now. During that time the household has had from 2 people up to 6 people living here at any given time, but in the last 3 years only 2. It has handled the capacity rather well, I must say. It has always fallen to me to maintain the system. Basically, just raking once every 2 months or transferring a wheel barrow load of composted material to a couple of compost bins once a year.

    When purchasing a compost system bigger is better so buy as big as you can for your situation. I installed mine in a day with the help of a friend to lift it as they're not heavy but awkward for one person. We weren't in a hurry. 

    The wood shavings work well by introducing carbon into the mix so it breaks down before being transferred to the garden, and I'm so pleased I'm not having to use precious water to flush a toilet as I'm on rain catchment where I am. I also don't have the problems of failed septic systems or the pump out and service fees and odours many people experience. I've worked for a septic cleaning and servicing company for the past 8 or so years up until recently as septic systems are the norm where I live, and have never needed any of their services. I suppose you'd call me a Shitologist haha

    All in all I'm very happy with the Clivus Multrum Composting Toilet System and the back up support by WCTNZ."

    "Awesome Walks is a new hospitality business in the Waitakere Ranges and needed bathroom facilities for use by our guests.

    After helpful consultation with Dylan we installed an Ecolet Waterless Composting Toilet and are extremely pleased with our decision. As well as being waterless, the system (contrary to my preconceived fears) is also completely odourless, easy to operate, clean and hygienic, and positively commented on and reviewed by our guests.

    We integrated the unit into a quirky setting, camouflage the vent pipe and make a real feature of it. We are thrilled with the result!"

    "I am a first time home builder with a rural off-grid property in the Tasman region. The planned dwelling is a small single occupancy house (55 square metres) on a sloping building site amongst regenerating forest.

    Opting for a composting toilet was a sensible cost-effective option due to financial constraints, plus the need to be independent due to no existing wastewater infrastructure. The composting toilet will be installed in a covered porch area.

    I found WCTNZ super helpful, answering my many initial questions with options from their wide range of products that best suited my situation. They also provided supporting documentation required for the building consent application regards AS/NZS and building code standards.

    Emails and phone calls were responded to promptly, with open discussion and advice about issues particular to both the property and council requirements. Communication also included follow up regards success with the building permit application. 

    WCTNZ  were recommended by two separate people for assistance with my build. I in turn would also recommend them to others.

    I look forward to purchasing products from WCTNZ and completing my building project."

    "When I started looking for a compost toilet to go with my off-grid tiny house, WCTNZ was recommended by a friend. I went online to look at their range and as I was living in Auckland at the time I visited their showroom.

    The person in the showroom guided me through the selection and knew every detail about the range and was easily able to answer all my questions and concerns. Very quickly I was able to single out the system I wanted, the Clivus Multrum CMLP, and the pedestal to go with it.
    The ordering and payment went seamlessly, and it was sent to a Mainfreight depot here in Levin where I could pick it up. I opened the various boxes to check all the contents with the enclosed list. It was quite comprehensive with every part and their quantity itemised. I found a couple of discrepancies and got on the phone immediately with WCTNZ who were very responsive and eager to clear things up. It turned out it was my mistake and nothing was missing or incorrect.

    I had to wait 6 months before installing the toilet as my tiny house was being built.  Consideration had to be given to how the system worked and especially where the pedestal and chamber underneath were going to be located. I was pretty nervous about it, but the manual was clear and precise in every detail, so that everything went well. I did most of it myself but got the builder involved when it came to cutting a large hole in the floor for the waste chute! It had to be bang on and obviously miss the floor joists, and then line up with the chamber underneath. Cutting the chute to the correct length was also nerve wracking as there wouldn't be a second chance, but again the manual was very clear with directions, so it was no problem.

    I am extremely happy with the Clivus Multrum system. I have now rotated the chamber out twice and with the addition of the Nature Flush Enzymes, and bulking agent after each solid it is composting down well in the 3 months it rests between rotations. The addition of a small extraction fan means there is no smell at all. The fan which was supplied was running surprisingly noisy and this was an issue as it runs 24/7 and I live in a quiet area with the bathroom next to my bedroom. However, WCTNZ replaced it at no charge after I informed them and it is now running fine.

    In conclusion I have been, and continue to be, very happy with the service and on-going support from Dasha and the team at WCTNZ. They obviously love what they do and have a wealth of experience of the various models they sell. But what I value most is that they back their product with excellent after sales service - they always take my calls, or call back when needed, are friendly, open to suggestions and respond positively."

    "Dylan at Waterless Composting Toilets NZ has customer service perfected. After buying a competitors system it wasnt long before the problems began, after receiving little support from my supplier I turned to Dylan.

    He took the time to listen to my problems and suggested of a cost effective solution. I would recommend Waterless Composting Toilets NZ to anyone looking to buy composting toilets, I wish that I had bought their system in the first place!"

    — Morgan Balderstone

    "We highly recommend this composting toilet. Having had the Clivus toilet now for over a year we have found it to be a 100% improvement on the mulching composting toilet we had previously. Our tenant is very happy with it. Clivus is an extremely user friendly system and easy to install.

    NO odor, no hassle, easy to clean. Looks like a normal toilet , can use like a normal toilet, except no flushing, which saves on water bills.

    We would use this for most house hold situations. Great."

    — Richard and Christine Robinson, Whangarei

    "I bought the Sun-Mar GTG compost toilet after researching ease of installation and use. 

    It’s installed in my caravan located in Coromandel. We have limited water supply so another reason for choosing a compost toilet. We bought a cheap camping compost loo and trialed it for a few months to make sure there’d be no issues with smell, then the Sun-Mar for a more permanent toilet. 

    I’d recommend the Sun-Mar GTG it meets all our requirements perfectly. From its design to easily to keep clean, I’ve had no issues with it plus had no issues with installation, found it very easy to install. 

    I’d purchase from WCTNZ again the toilet arrived in perfect condition and didn’t have to wait long for delivery."

    — Carol, Coromandel

    "We purchased and installed a Clivus Multrum CM10 at our family bach and couldn't be happier with the service from WCTNZ and the product. Communication from the team was clear, informative, and totally helpful.  We chose the CM10 because of it's size (it needed to be installed under the bach), the cost (much cheaper than traditional septic tanks), the advice and support from the WCTNZ team, easy maintenance required, but mostly because it uses zero water (we are on rain/tank water).

    We've had the CM10 for a few years now and continue to enjoy the ease of use and functionality. It performs as decribed - no smell, no flies, and easy maintenance - way beyond expectations. It continues to work perfectly for us.

    Since installation we have replaced the 24V fan (it runs 24 x 7 x 365), but WCTNZ were quick and helpful, and the replacement arrived within days of ordering. Over time we have also ordered cleaning products, extra bacteria, and more bales of woodchips, which have always arrived in a timely manner.

    I have no hesitation recommending the WCTNZ team for their knowledge, expertise, and responsive service ... and the Clivus Multrum CM10 for use at a regularly used family bach."

    — Ty, Wellington

    "I just wanted to write and let you know how great your service has been. We needed some options for our waterless loo and other companies weren't able to help. However, WCTNZ has solved our problem."

    Sun-Mart GTG Composting Toilet in NZ bathroom

    "We chose the Sunmar GTG toilet for our rural new build in Twizel (Mackenzie Region). We went for a composting/waterless option as a cheaper option than septic tanks and tricky environmental consents.

    We have been in the new house for 4 weeks now and the toilet is fantastic! I thought there would be a slight odour, but there is absolutely zero. Very easy to empty and clean, and the minimal design looks amazing in our lovely new bathroom (see picture). Nobody on first look even picked it as a composting loo!

    Ordering and delivery through WCTNZ was easy and there are loads of options for consumables.

    Plenty of our guests have been impressed and are looking at one of these units for sleepouts and houseboats. 100% recommend this product!"

    — Tracey, Canterbury

    "I can thoroughly recommend Dylan at Waterless Composting Toilets WCT.

    Having no knowledge of compost toilets I phoned around and e mailed a few companies.

    Dylan promptly replies to my request with a phone call. He asked me what my needs were and found an economical match for me in the CM2. We had no power to the site and Dylan quickly came up with a solution for the vent. He also educated me on how to look after the composting side and what my needs would be for the compost bin arrangement. What impressed me was that he was not about selling a product, he was concerned with following through on a process so the whole thing worked to my advantage. He also suggested other biophilic possibilities and we discussed wind and solar power at length. Dylan is very knowledgeable about the things we should be doing as well as simplifying the understanding and the economics. Thank you Dylan Timney at WCT."

    — Sally Freebairn,, Auckland

    "From my first contact with Waterless Composting Toilets (WCT) I received friendly, informative service in a prompt manner. My partner and I received personal assistance to help us choose the right system for us.

    Even though we went for one of the less expensive models we still received service as if we were purchasing from the top end of the range. When we encountered some teething problems (due to our location rather than the system itself) Dylan from Waterless composting toilets made it his personal mission to help us get our system working at an optimum level.

    The after purchase service we received was excellent and I would highly recommend both the products and the after care service of this company."

    — Lisa, Waiheke Island

    "We have had the CM8 installed at  our bach for over a year now and we are very happy with it .

    This summer we had lots of visitors so it had a heavy work load and coped very well and saved us litres of precious water.

    We are most impressed with the lack of any smell compared to a recent visit to a remote property using a long drop worm system, the smell was unbearable ! If ours does smell it is a sweet earthy aroma."

    Paul Scopas

    "I reached out to WCTNZ to see if they could help me troubleshoot a composting toilet I had bought from a different company whose product turned out to be very problematic.

    I did reach out to the original supplier first, but they weren't able to offer any help, so upon recommendation from my tiny house builder, I approached WCTNZ and they readily fixed my problem."
