Thank you,

Hello Shaun. I am going to suggest our 10-058 shower door roller and bumper kit as a replacement. There is also a diagram I placed below of the kit so that you may have a closer look. Do you think you could make this work for you?
I'm afraid we don't sell brand-specific roller kits. I'm also not familiar with the Llumia brand in general, so I don't know what kind of hardware they use; without a reference, I don't believe I'll be able to find a match in our inventory, either.
You may be better served contacting the original shower manufacturer directly.
