The fixture itself is very attractive, substantial and high quality.  The vertical approach is unique; if too unique, it would not be difficult to reorient it and use it as a traditional horizontal holder.  However, that would require drilling new holes; the fixture would cover the old holes.  The attachment hardware and instructions do not reflect the quality of the fixture.  The instructions cover numerous Kohler products and are consequently rather muddled.  The attachment hardware might work if the instructions were correct but  I ended up making a trip to the hardware store for correct attachment hardware.
