Where to get lightweight bathroom curtains

[Rizzlekicks]

I have just bought two tension rods as I want to put some curtains in our bathrooms. The frosted glass is not adequate enough. As there is already frosted glass and the curtains will be held by a tension pole, they need to be lightweight. Where can I get something nice and not too elaborate? The window size is 120cm W x 100 cm H

Have you thought about using frosted film over the glass to have more privacy?

Could you use a nice shower curtain? Less likely to go foosty from the damp and really lightweight
