Custom closets are usually built from engineered wood panels with a melamine or laminate face, MDF, plywood, solid wood or wood veneer, with wire or metal for some parts. In humid South Florida, choose sealed, moisture-resistant surfaces, rust-resistant hardware and a layout that lets air move, and keep indoor humidity below 60 percent.
Key takeaways
- Wood takes on and gives off moisture as the air's humidity and temperature change (USDA Forest Products Laboratory), so sealed surfaces matter here.
- UF/IFAS Extension notes that in Florida's humid air, a scratch through a protective coating can let rust start on metal.
- Closet Décor & More builds with wood that has a melamine coating that resists moisture, stains and fading, in 13 finishes.
- Ask any closet company how cut edges are sealed and what the hardware is made of.

What’s The Word on Custom Wood Closets?
Wood is one of the oldest and most traditional building materials used in custom closet design and depending on how you choose to use your closet, it may be the material that you choose to work with. Durable and lightweight, plywood is oftentimes used in closet design. You will also find that professional custom closet designers choose sustainable, eco-friendly types of wood during installation that come in a great selection of stains to match your aesthetics. Wood closets take a bit of skill in measurements and know-how to install, which can make a big difference in choosing the professional you have work with you. You may find yourself faced with the choice of 100 percent real solid wood, or compressed wood during your custom closet build. Whichever material you choose will surely make a gorgeous, well-organized space. Your pick of what type of wood material to use depends on your budget and needs, which can all be answered by a professional closet installer.
Metal Shelving and Racks in Your Custom Closet Can Add Modern Flair.
Metal racks and shelves are not a new item in custom closet design, but with updated colors and organization options, this long-trusted material can update a closet or kitchen pantry quickly. From wire racks that hold up for years to come with the right installation to sleek metal shelves that are durable for heavy loads; these materials are still a go-to choice for kitchen pantries, linen closets, kids closets and walk-in’s that need an extra boost of organization options. Metal mixed with woods have become a recent trend over the past few years. Many custom closets will include beautiful solid wood cabinets and sleek metal shoe racks - seamlessly blending the two materials for a modern aesthetic.
Are Melamine and MDF the New Black?
In recent years, melamine has become a very popular building material for everything from dishes to custom closets. Melamine is essentially a type of hard plastic resin that is super durable, fire-resistant, and tolerant to wear and tear. When used as a material to build custom closets, melamine resin is the outer layer over high-density fiberboard, which creates a high sheen look that usually comes in black, white or woodgrain.
Smooth, durable, and flexible as a building material- MDF (medium-density fiberboard) has become a popular option for custom closets in lieu of wood. A bit less expensive than traditional wood custom closets, MDF is utilized and built in a similar style but helps those looking for a cheaper option than solid wood custom closet build-outs.
Extra, Extra Extra! All the Custom Closet Additions You Need!
The main portion of your custom closet build-out will include shelves, racks, and drawers but there are several additional items that you will want to consider as materials for your new space. Closet rods, baskets, tie racks, mirrors, lighting, and free-standing countertops can all be added into your design to customize your closet even further. Working professionals will have different needs than a retiree versus moms, who will want useful space for their own needs and for their kids. Full-length mirrors are a great addition to any custom closet, in addition to a chair or bench to sit on while lacing up your shoes. Your custom closet won’t consist of just shelves and drawers, so make sure to ponder what will give you the greatest use of your space!
Your Closet, Your Choice!
Custom Closets are usually designed with the help of a professional who helps you map out a blueprint of diverse closet space solutions. When choosing the materials with your professional closet designer, make sure to ask about how the material you choose will stand up against the elements, how it will stand the test of time, whether it matches your current aesthetics and how you can build it based on your personal style and budget.
In addition to choices in custom closet building materials, you may want to add additional organization systems that will help maximize your space. Think jewelry trays, adjustable hanging rods, pants racks, fold-out ironing boards, drawer organizers, laundry bins, and more! The material you choose to build out your custom closet with should match well with your extra build-ins to create an appealing, functional and spacious custom closet built for you
When choosing material for your custom closet some of the most important things to remember are style, budget, and durability. Any custom closet design should fit your organization and lifestyle needs. Whether you choose traditional solid wood for classic elegance, sleek metal shelving, or new melamine sheen - your custom closet is yours to design as you see fit for your unique space.

How humidity affects closet materials
The USDA Forest Products Laboratory's Wood Handbook explains that wood is hygroscopic: it takes on moisture from the surrounding air, and how much depends on relative humidity and temperature. Many of wood's performance problems come from those changes in moisture content. UF/IFAS Extension adds that in Florida's warm, humid climate, wood, cotton and leather can decay and develop odors, and metal can rust where a coating is scratched. EPA recommends keeping indoor humidity below 60 percent.
Material by material in a humid climate
- Melamine and laminate. A resin face fused to a core board. The face resists moisture and stains; cut edges and drilled holes are where the core can be exposed, so ask how they're finished.
- MDF and particleboard. Smooth, stable and affordable as cores. Left unsealed, they take on moisture like any wood product.
- Solid wood and veneer. Warm and premium, but they move with humidity, so the finish matters.
- Wire and metal. Affordable and open to airflow. Coated wire can rust where the coating chips.
What Closet Décor & More uses
Our closet systems are wood with a melamine coating that resists moisture, stains and fading.

See closet colors and door styles, hardware options and wall-mounted vs. floor-mounted systems. Materials do half the job; preventing closet mold covers the other half.
Frequently asked questions
- What is the best closet material for Florida's humidity?
Choose sealed, moisture-resistant surfaces, such as melamine- or laminate-faced panels with finished edges, plus hardware that resists rust. Solid wood works too if it's well finished, but it moves with humidity. Whatever you pick, keep indoor humidity below 60 percent, as EPA recommends, because no closet material makes up for a damp room.
- Is melamine the same as MDF?
No. Melamine is a resin surface fused to the face of a core board; MDF (medium-density fiberboard) is one of the boards it can be applied to, along with particleboard. When people say "a melamine closet," they mean the finished surface. Ask which core a company uses and how it covers exposed edges.
- Will wire shelving rust in a Florida closet?
It can. Wire shelving is usually coated, and UF/IFAS Extension notes that once a protective coating is scratched, moisture and oxygen in Florida's air can start rust and corrosion. Rust can then stain clothing, which is the same reason UF/IFAS warns against metal hangers in closets. Lower humidity slows it down.
- What finishes does Closet Décor & More offer?
Thirteen: White, Antique White, Arctic, Concrete, Cloud, Drift, Ash, Licorice, Tahoe, Dakota, Black, Vintage and Dune. Door and drawer fronts come in nine styles: Flat Panel, Modern, Raised Panel, Pillowtop, Shaker, Allegra, Slim Shaker, One-Piece Shaker and Milan.
