If you are planning a kitchen, closet, built-in or vanity anywhere from Miami-Dade up through Broward and Palm Beach County, you will hit the same fork in the road: buy ready-to-assemble (RTA) cabinet kits, or pay for fully custom-built cabinetry. Both get you doors, boxes and drawers. They do not cost the same, they do not take the same time, and they do not give you the same control over the finished job.
This is a straight comparison. Here is where each option wins, and where it quietly costs you.
What You Are Actually Comparing
Ready-to-assemble kits
An RTA kit arrives as flat, machined parts – panels, doors, drawer fronts, hardware – that you or your installer assemble on site. With a catalog kit, sizing comes from a list of standard widths and depths, with a limited set of finish and material choices. The cabinet is designed once, made in volume, and shipped.
Fully custom-built cabinetry
Custom cabinetry is measured, designed and built for one specific space. Every box is sized to your walls, every filler and corner is resolved before installation, and materials, finishes and interior fittings are chosen to spec. It is a one-off build, and it is priced like one.
Cost: Where the Real Money Goes
The headline difference is labor, not wood.
RTA kits keep cost down because the expensive steps are done by machine. Panels are cut and bored on production equipment, not by hand. Assembly is the last, simplest step – and you can do it yourself. You are buying parts, not a project.
Fully custom cabinetry costs more because of the hours behind it: design time, a shop that builds one project at a time, finishing, delivery, and an installer who fits every box to a wall that is rarely perfectly square. You are paying for labor, fit and someone else owning the outcome. For a line-by-line look at what goes into a custom quote, see what custom cabinets really cost in South Florida.
The practical rule: if your space fits standard sizes, full custom is paying for flexibility you may not need. If it does not fit standard sizes, a catalog kit will force you into fillers and compromises that show.
Timeline: What Sets the Pace
Catalog RTA kits are usually the faster route. Parts are cut and shipped, then assembled on site once they arrive. There is no finishing schedule and no shop calendar to wait on.
A full custom build runs on a shop calendar. Design, approval, cutting, assembly, finishing and installation happen in sequence, and a change at one stage moves everything behind it. If your project has a hard date – a closing, a rental turnover, a family moving in – plan the schedule around that date from the first conversation.
Control: Materials, Measurements, Installation
This is where the argument gets more interesting than price.
With catalog RTA kits, you control assembly and installation, but the manufacturer controls the sizes, the materials and the finish list. If the catalog does not carry it, you are not getting it.
With custom cabinetry, you control the design. You choose the panels, the edge banding, the drawer hardware, the interior layout. You pay for that control, and you pay again if you change your mind mid-build.
Where RTA Kits Win
- Standard-size kitchens, closets and vanities where catalog widths land cleanly.
- Budgets that need to stay predictable before the first panel is cut.
- Projects with a deadline that leaves no room for a long build schedule.
- Buyers who want to assemble and install themselves and keep that labor cost.
Where Custom-Built Wins
- Odd geometry: angled walls, tight corners, ceiling-height runs, sloped soffits.
- Non-standard depths and heights, or a design that only exists on your drawing.
- Materials, veneers or finishes that no kit line stocks.
- Jobs where someone else must own design, fit and finish end to end.
The Middle Path: Custom Parts, RTA Assembly
Most South Florida projects do not sit neatly in either camp. They need exact measurements, but not a fully managed build.
That is the gap M11 fills. You send your measurements, a sketch or a cut list. We cut, machine, edge band and label the parts in our own South Florida shop – panels, doors, drawer fronts, or a complete custom RTA cabinet kit for your kitchen, closet, built-in or vanity – and you or your installer assemble and fit it on site. You keep custom sizing and material control. You keep the simplicity of RTA assembly. You can also choose how much of the work we do: cutting only, cut plus machining, or a complete kit.
For contractors, handymen, designers and architects working across Miami-Dade, Broward and Palm Beach, that combination is often the better fit than either extreme: a catalog kit that does not fit the room, or a full build the project does not need. Trade partners can see how we work on our For Trade page.
And when a project does call for someone to own it end to end, full design-to-installation service is also available, for a deliberately small number of projects.
How to Choose for Your Project
Work through it in this order:
- Measure your space honestly. Note every wall that is out of square and every run that is not a standard width. Our cut list method walks through it step by step.
- Decide what control you actually need – sizes only, or materials and finish too.
- Put a real date on the project and count backward.
- Compare cost on the full scope: parts, assembly labor, installation, and the cost of fixing misfits later.
If your numbers are standard and your deadline is tight, catalog RTA kits are the sensible call. If the space is genuinely custom and you want one team to own the result, a full custom build earns its price. If your space is custom but you are ready to assemble it yourself or with your own installer, custom parts assembled on site is the option most homeowners never get shown.
The Bottom Line
Catalog RTA kits sell speed, price and predictability. Custom-built cabinets sell fit, control and a one-off build. For many South Florida projects, the best value is neither side alone, but parts made to your actual measurements and assembled on site – which is exactly how we work.
