A custom walk-in closet costs $1,000 to $8,000, while a custom reach-in closet costs $500 to $3,800. The cost to build a custom closet depends on the size, features, and materials. Large walk-in closets require more storage pieces, increasing costs, while smaller reach-in closets are cheaper because they require fewer materials.
Wire shelving is the cheapest closet material but doesn't increase home value as much as other materials. Laminate and melamine are good mid-grade options. Custom wood closet organizers cost the most but are much more durable and provide a high-end look.
A prefab closet organizer is cheaper than a custom closet but offers fewer features and options to choose from, which may limit its usefulness compared to a custom organizer designed specifically for your needs.
