Ideas for a shower curtain rod for a free standing bath tub

I'm looking for ideas on how to make a shower curtain rod to surround a free standing tub. I enjoy a relaxing bath, also enjoy a quick shower and don't have room for both in my tiny home(450 sq. feet). I chose the tub, the rods in hardware stores & such are beyond my budget. All ideas are much appreciated. Conduit?
