Hello! Wire shelving is a great option for laundry rooms, considering the amount of moisture and heat that is usually generated in laundry rooms. To find an option best suited for your space, we recommend you look online at Ikea, the Container Store, etc.
In closets, we generally do not recommend wire shelving, seeing as wire is more likely to bow sooner than wood cabinetry. Here at Best & Co, we custom mill our closets from hardwood to best fit your needs. For more information on our services, you can call (212) 776-1111 or visit our website: http://www.bestandcompanynyc.com/
Best of luck!
