How to have a glass wall side to a shower with a sloping ceiling?

We have a shower in the corner of our bathroom. It a cubicle with wall on 3 sides, curtain on the 4th. It is small and gets mildew so we'd like to replace the temporary wall with glass. This has been problematic as the bathroom has a sloping ceiling with the lowest point at 2m. It appears that all offerings at DIY stores are over 2m. A glass specialist told me they could provide the glass but not the fixtures and fittings and advised me to get these first. A bathroom specialist then told me that its difficult to buy fixtures and fittings as they usually come with the shower cubicle/glass wall. Any advise greatly appreciated.
