Customer Reviews

QUALITY WOOD AND QUALITY PEOPLE!!!!

I had an awesome experience with SDS. From start to finish, the customer service was top-tier – James was incredibly responsive, genuine, and helpful. I also want to give a special mention to Tony, the head of DIY, who went above and beyond to give clear, practical advice that made a huge difference to my project.

What stood out most was that it felt like a real partnership – not the usual experience where you’re left guessing or being upsold. These guys genuinely wanted to help me get it right, and the quality of materials matched the service. Highly recommend SDS for any DIYer who wants solid support and trusted products.

Also worth noting I did my due diligence on a number of providers in Sydney and even went and checked out different custom builds located in the CBD at gyms so I could compare quality. There was a monumental difference in quality,

Very happy

Bought about 150 pieces of sauna wood and every one of them was perfect. No knots, no bowing, no issues at all. Interstate delivery was fast also. Very happy.
