Stainless Steel Handrails (for Bathroom)

Planning to install some handrails for bathroom and toilet (300mm and 450mm long). Looked on ebay and Bunnings. Ebay has 19mm diameter ones for just over $20 each and Bunnings has 32mm diameter ones for around $40-45. But I am looking for ones with diameter of around 25mm in between, and hopefully cheaper than Bunnings, just wondering if anyone can point me in the right direction. Thanks in advance.
