Evolution Window's St Marys. They use AWS extrusions, all Australian owned and manufactured.

Have a look for entry door handles. They can be adapted to grab bars that don't look like nursing home fixtures by turning them 90 degrees. http://www.handleworks.com.au/product-category/entry-handles/?per_page=-1 Handleworks is one of my preferred suppliers due to their wide range. They don't have a wave grab handle exactly like yours but they do have lots of other door handles that could work equally well as grab handles in a bathroom. As they are designed for external use they should be able to cope with the moisture in a bathroom. There will be other door handle suppliers with similar wave-shape entry door handles to your grab rails. Best of luck Dr Retro of Dr Retro House Calls
