Yes, 12-inch shelves are often considered the standard closet shelf depth for storing folded clothing, shoes, and small containers. However, if you plan to store bulky items such as blankets, baskets, or cleaning supplies, you may want to go deeper. For specialized layouts, an adjustable system can give you more flexibility.

On average, building a custom or built-in closet costs around $2,100. However, the total price can range from as little as $500 for a simple DIY project to $6,000 or more for a large, high-end custom closet. Most projects typically fall between $1,500 and $5,000.

The final cost depends on several factors, including the closet's size, type, materials, and features. Here is a general cost breakdown by closet type:

• Reach-in closet: $500 to $1,500

• Walk-in closet: $750 to $5,000

• Wardrobe: $2,000 to $6,000 or more

Choosing a prefabricated closet system is generally less expensive than a fully custom build. The scope of design and construction services will also significantly impact the price.

You can design your own closet, but it’s usually better to hire a professional to do the work for you. Not only will you get years of design experience to guide you toward the right layout and material choices, but you’ll also only pay slightly more hiring a professional than you would creating your own plans and hiring a carpenter. A high-quality closet designer can provide insight into how to lay out your closet, and they may be able to find you a good deal on the carpentry or complete the work using an affordable, in-house team.

You can modernize an old-looking closet by just painting it, but beyond that, consider electric elements like recessed or accent lighting. If this is a large and deep closet, you can consider adding an island to the middle or a nice ottoman on a rug. Luxury closets will have even more items, like felt-lined drawers for watches and jewelry, in-wall safes, electronic shoe storage, or a tablet catalog of their items.
