Cutting out the middle person in the supply chain and controlling production standards enabled Millen to offer good quality products at a competitive price.
Having smaller showrooms and local warehouses means a closer working connection between the supplier and customer, Xing said.
''Our shop is the showroom and our warehouse is out the back. We deal directly with our customer.''
Millen moved into Whangārei last October because of the recognised growth in construction, house sales and renovations in Northland, Xing said.
''The property business is spreading all around from Auckland to other places. We have stores in Tauranga, Hamilton and Wellington, too.''
Millen has its eye on all corners of the market, selling to trade, the public and in bulk to construction companies. The Whangārei store is hoping to build on the local bulk potential but believes the home DIY customers, small builders and tradies are its main market.
''We're happy when people doing their renos come to us. Most of our customers are middle to older aged. They are at the stage or improving their homes or buying a second home and doing it up.''
With a nearly 20-year presence in New Zealand, some customers are second time around. Xing gave the example of a woman who returned 10 years later to get a replacement shower part and was delighted to find it fitted the original components.
All parts are exchangeable, with a long guarantee, Xing said.
While the showrooms carry a smallish range of modular bathroom and kitchen products such as benches and taps, a fuller line-up can be seen online and on Trademe, she said.
Millen stores do carry a large range of tapware, mainly because the company's owner is a designer with a thing for tapware.
Some products, such as irregular sized or shaped shower doors and stainless steel trays, can made to order.
The one-stop shop can also put together a tailor-made package to suit customers' needs.
Xing said store managers are trained or can call on others to advise with design, ''but a lot of customers come in with their own ideas and know what they want.'
