Tiny HouseCouncil ConsentGreywaterNature Loo
Consented tiny house with composting toilet and greywater system"I achieved council consent and am extremely happy with both the service from WCTNZ and the choices I made."
— Rosina, KerikeriRead full customer story
"The WCTNZ team did an amazing job from start to finish and I am so very pleased I discovered them. I required a composting toilet and grey water waste system for a tiny house that would achieve council consent. New to this game I had many questions and they were informative with their knowledge and advice and nothing was too much trouble."
"Venturing out from a lifetime use of a flushing toilet system, when embarking on a new life in a tiny home requiring composting toilet, I was initially somewhat nervous about choosing the right product. I thoroughly researched the differing types of composting toilets on the market and discovered WCTNZ and their Nature Loo Alectura Premium model."
"Kudos to the designer of this system; it not only looks aesthetically pleasing, it is straightforward to use on a daily basis and requires very little maintenance going forward. The bonus of an extractor fan eliminates any smells – more so than a standard toilet as the inbuilt fan extracts all smells from the bathroom 100% immediately."
"Throughout my decision-making process, the staff at WCTNZ offered exemplary service, providing suggestions specific to my needs. I had also required a grey water waste system and they guided me through varying choices, deciding on the GreyFlow, Passway and Dripper Line system."
"With the assistance of a plumber the installation of the Alectura and Grey Water Waste system was fairly straightforward. I achieved council consent, and am extremely happy with both the service from WCTNZ and the choices I made."

CampgroundPublic UseClivus MultrumLong-Term Use
Over 10 years of campground use"The Little River Campground has been using the CM40 for over 10 years with no issues."
— Marcus, Little River Campground, Banks PeninsulaRead full customer story
"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."

Community FacilityOff-GridSolar FanClivus Multrum
Off-grid community toilet with solar ventilation"People possibly expect it to be like a smelly longdrop, but it is a whole lot more pleasant."
— Louise and Diana, Huia Road Horse Club, AucklandRead full customer story
"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!"
"Overall, we are very satisfied with the Clivus Multrum CM8 and Dylan from WCTNZ was always helpful when we were enquiring about it."

Backcountry HutsPublic UseSustainable ToiletsClivus Multrum
Backcountry hut accommodation on The Old Ghost Road"Introducing these helped measurably with our key objectives of providing a more sustainable, effective and pleasant toileting experience."
— Phil Rossiter, Old Ghost Road, South IslandRead full customer story
"Operating backcountry hut accommodation on The Old Ghost Road comes with a number of unique challenges and service requirements. One of the key challenges is to provide sustainable, effective and 'user-friendly' toilet facilities for visitors. We have long been believers in composting toilets, however not all composting toilets are built equal - not just in terms of their performance, but in terms of their servicing and maintenance characteristics which are important considerations for any backcountry operation."
"In late 2017 The Old Ghost Road upgraded its toilets to Clivus Multrum composting toilets supplied by Waterless Composting Toilets New Zealand. Introducing these helped measurably with our key objectives of providing a more sustainable, effective and pleasant toileting experience for users on The Old Ghost Road. Like most things, composting toilets have their place and take some understanding and commitment, however if applied and maintained appropriately, we believe they provide an excellent and often superior solution to other toilet and waste management options."

Tiny HouseAfter-Sales SupportClivus MultrumInstallation
Tiny house system with strong after-sales support"What I value most is that they back their product with excellent after sales service."
— Ben, Manawatū-WhanganuiRead full customer story
"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. 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 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."
"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."

Family BachRainwater SiteClivus MultrumLong-Term Use
Family bach with zero-water toilet system"It performs as described - no smell, no flies, and easy maintenance - way beyond expectations."
— Ty, WellingtonRead full customer story
"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 its size, the cost, the advice and support from the WCTNZ team, easy maintenance required, but mostly because it uses zero water as 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 described - 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, 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."

Tiny HouseNature LooLow Maintenance
Future-proofing a tiny house and art studio"WCTNZ® are a pleasure to work with. They are only a call away and always available when needed."
— Peter, PihaRead full review
"I needed to replace a long-drop that wasn't functioning well, and I wanted to replace it with an organic solution that was also affordable."
"I spoke with WCTNZ at the Tiny House Expo and it quickly became clear to me that they were a company I could trust. They had a wealth of knowledge and great personalities, too, so they were pleasant to deal with."
"I gave WCTNZ the brief: I wanted a reasonably sized system that would be low-maintenance and would also future-proof the property if the use increased or if the property had to be sold in the years to come. They recommended the Nature Loo Classic 850, and this is what I went for."
"I installed the Nature Loo Classic 850 in an outhouse adjacent to my tiny house/art studio in Piha. I've been using it for about 5 months and still haven't filled up a chamber, so the maintenance is very low!"

Building ConsentRural SiteOff-Grid
Support for a rural off-grid build"They provided supporting documentation required for the building consent application."
— Deb, TasmanRead full review
"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 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."
"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."

The additional help with you providing other building consent numbers that had been approved was awesome, and as one of them was in the same area as mine, was invaluable."
"I also really appreciated that just me providing my phone number was enough for you to look up all the information about the system I had purchased."
"Thank you so much for your kindness, and the knowledge and assistance you give to your customers. Thank you again."

— Janine and Simon J., Hihi PeninsulaRead full review
"We unpacked the Clivus Multrum system today and we are very happy (excited even) with the system. We will probably install it in the next 2-3 weeks, because we have to build the bathroom first, now that we can see how the system will fit in and under the space and on the section. Exciting. Thank you for excellent service and all the best to the WCTNZ team."

"We live off grid in rural Auckland. We recently replaced our old Ecolet model 65A with a brand new 25A model. The old system was around 12 years old and still running but it was getting a little tired."
"We've been so happy with the way the Ecolet functions and how easy it is to empty the compost tray, we gladly invested again in the product as we know the workings of it and trust it."
"We like the great design of the toilet and visitors always comment how easy it is to use and are surprised that its odour free. If used in keeping with the instructions you can't go wrong."

"I have been using my Clivus Multrum composting toilet in my small / transportable home for almost 2 years now. Any issues I have come across in that time have been dealt with by seeking advice from the incredibly helpful staff at WCTNZ. It is a process that requires guidance if you are new to composting loos and they are always happy to provide the consumables needed and advice. It certainly has been a learning curve for me but I know that the support is there with either a phone call or a visit. Thanks team!"

Off-Grid SiteProduct MatchingAdvice
Finding the right economical match"He was not about selling a product, he was concerned with following through on a process."
— Sally Freebairn, kiwicompass.co.nz, AucklandRead full review
"I can thoroughly recommend Dylan at Waterless Composting Toilets WCT."
"Having no knowledge of compost toilets I phoned around and emailed a few companies. Dylan promptly replied 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."

— Christine and Brent, South CanterburyRead full review
"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."
"We decided to buy from WCTNZ because they had the best information and their video tutorial show you how their system works.

Long-Term UseClivus MultrumRainwater Site
Close to 10 years of household use"All in all I'm very happy with the Clivus Multrum composting toilet system and the back up support by WCTNZ."
— Mike, Waiheke IslandRead full review
"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. It has handled the capacity rather well."
"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."
"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."

Clivus MultrumNo OdourHousehold Use
A major improvement over a previous system"NO odor, no hassle, easy to clean. Looks like a normal toilet."
— Richard and Christine Robinson, WhangareiRead full review
"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."

Caravan toilet in Coromandel"I’d recommend the Sun-Mar GTG, it meets all our requirements perfectly."
— Carol, CoromandelRead full review
"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 trialled 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 easy to keep clean, I’ve had no issues with it plus had no issues with installation, found it very easy to install."

Rural new build in Twizel"There is absolutely zero odour. Very easy to empty and clean."
— Tracey, CanterburyRead full review
"We chose the Sunmar GTG toilet for our rural new build in Twizel. 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."
"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!"

"I bought a tiny house on wheels and was going to take out the composting toilet that came with it and replace it with a Bambooloo but I thought I would leave it in to try it and I’m glad I did. It’s great!"
"Our tiny house is completely off grid in an isolated area with 1kW of solar. We use the tiny as a weekend getaway every 2nd or 3rd weekend with around 2-4 people. It lasted almost a year without needing emptying. I was very impressed."
"It was easy to use, just like a normal toilet. Except instead of flushing, you would just add a scoop of dry mix. The compost it produces is beautiful."
