Our History


Grahame and Jeanette Cook had a dream to start up a business they could call their own. By day, Grahame worked full time at Complete Hardware in Eastwood, by night he and Jeanette started Cook’s in the garage of their North Rocks family home.

They worked tirelessly around the clock establishing a customer base, delivering product well into the night to ensure customers had material to work with at the start of the next day.

1976 -1995

The business had outgrown the garage, a new property was purchased - still in North Rocks - with a warehouse and trade store built to accommodate demand.

Between 1993 and 1995 growth remained strong and two new branches were opened – Castle Hill and Windsor.


Grahame sadly passed away. Jeanette was determined to ensure the business remained strong, knowing it’s what Grahame would have wanted. Over time, Cook’s continued to develop, building strong relationships with suppliers, and growing its footprint.


By 2014 with five branches in NSW, it was time to tackle the QLD market. First with the opening of a trade store and showroom in Brendale, followed by Sumner Park in 2015 (trade store and showroom) and East Brisbane (trade store) during 2019.



Cook’s continues to be family owned and operated, with a highly successful business model, and head office remaining at the North Rocks location. Cook’s are made up of eleven trade stores, a home builders division, commercial projects division and six retail showrooms – all across NSW and QLD. We are Sydney’s largest independent supplier of plumbing supplies, with over 200 dedicated and passionate employees.

We are a foundation member of Plumbing Plus - a national buying group with over 320 stores around Australia. That means seriously competitive deals for you with all product groups across all plumbing and bathroom products.

The culture that started at Cook’s by Grahame and Jeanette back in 1969, remains embedded within the business today.
