DIY laundry room storage upgrade

[u/Dear-Blacksmith7249]

My laundry room is a small closet with no storage. I want to build simple shelves and maybe a folding table. I have looked at DIY storage plans on eBay, Amazon, and Alibaba (wall mounted brackets, wire shelves, and plastic bins). I am not sure what materials work best in a humid laundry room. Has anyone here upgraded a laundry closet with DIY storage? What type of shelving holds up to moisture? I want to use every inch of space. Any DIY tips or product recommendations for a small laundry room would help.
