No need to put glass.

Mine I just put acrylic panel (got many pattern) framed with aluminum. IT is not the whole stretch from wall to wall but just the shower head side. the other half of opening I ca just put shower curtain. That separate the shower and the sink side. I think should be around RM400.

To prevent the water from shower side to flow to sink side, the floor tiles on the sink side is raised by additional tile height. I just epoxied same tile on top of existing tile and finish it with edge plastic at the acrylic partition lone.
