About Us

Slimline Rainwater Storage Tanks in Perth, regional WA and Australia wide.

John and Robyn Auld established Slim Thin Tanks in 2011 to introduce the stylish and space saving Australian made Thin Tanks to the people of metropolitan Perth.

They lived on a farm and always had fresh rainwater to drink and when they visited family in Perth they had to bring their own water because they didn’t like the taste of mains water. After building their retirement house in Victoria Park, John set about looking for a rainwater tank suitable for the confined spaces of an urban block. He found the only viable solution in Adelaide and quickly became the Perth Distributor of Thin Tanks.

In 2014 John passed the business on to his son Clayton and daughter in law Sharon.

Clayton previously worked across Australia in the drilling industry and worked on the farm during rostered breaks. He has a wide range of experience with tools, equipment, and machinery. From working in isolated and remote parts of the country, Clayton has experience in problem solving and being creative with finding solutions. 

Clayton is meticulously accurate when installing a tank and will not leave the job until it is completed to perfection. Clayton is the man to talk to about the design and dimensions of the tanks, pumps and installations. Clayton will design the right package for your requirements.

Sharon is the assistant installer and hands Clayton the tools he needs to get the job done. She also does all the administrative work like quoting, filing and finances. Sharon has a long background as an Administration and Operations Manager in the Northern Territory, prior to moving to WA with Clayton.

Slim Thin Tanks is a family business invested in the family. We hope to be successful in all that we do and to one day have the kids working with us.

We not only have Thin Tanks, we also have an alternative line of slim line tanks, and continue to work on being able to provide a range of products to complement the tanks and the environment.
