Hi, I am trying to find the right size door to hang as a barn door in my laundry. I thought it would need to be slightly taller than the door opening but I can't seem to find any online that are the right size. The opening is 820mm x 2030mm. All the doors I can find are 2040mm tall. Would this height work as a barn door? I think this width (870mm) would be suitable https://www.bunnings.com.au/hume-2040-x-870-x-35-internal-door-primed-mdf-accent-hag9_p2026212
Thank you for your help. I have have found all of the answers to my other questions provided by the Bunnings community to be incredibly helpful so far!
