Cabinet quality hides in the parts you never see again once the doors are on: the box — plywood or particleboard, judged by grade rather than name — the hinges and slides, and the finish. Here is what actually matters, and what you can skip.
Two kitchens can look identical in a showroom and be a decade apart in how long they last. The difference is rarely the door you are staring at — it is the box behind it, the hinge inside it, and the finish under the paint. Learn to read those three and you will never overpay, or under-buy, again.
What they search at midnight “are particleboard cabinets any good / plywood vs particleboard” — the honest answer is “it depends what grade,” and here’s how to tell.
The cabinet box (the carcass) is built from one of three materials, and it decides how the kitchen ages:
| Material | Strength | Moisture | Best for |
|---|---|---|---|
| Plywood | Highest — holds screws best | Good | Premium boxes, sink bases |
| Furniture-grade particleboard | Good when thick & dense | Fine if sealed | Most quality frameless boxes |
| MDF | Smooth, stable, heavy | Poor if unsealed | Painted doors, not wet boxes |
What matters more than the name is thickness and edge quality: a dense, fully-finished ¾″ panel with clean banded edges outlasts a thin, chip-prone one whatever it is made of. Flip boxes are ¾″ frameless construction with finished interiors — the panel edge is the front of the cabinet, so it has to be good.
That is the general rule. Here is what is actually in a Flip box, panel by panel — the numbers a spec sheet gives you and a showroom does not.
| Part | Thickness | Build |
|---|---|---|
| Sides, shelves & bottom | ¾″ / 18 mm | Plywood or particleboard, creamy-white melamine laminate on both faces, PVC edge banding in the matching colour |
| Drawer bottom & back | ⅝″ / 16 mm | Same construction — melamine both sides, matching PVC banding |
| Back panel (plywood build) | ⅛″ / 3 mm | Thin plywood back in a matching colour, slotted into grooves cut in the sides, top and bottom of the box |
| Back panel (particleboard build) | ¼″ / 5 mm | Matching-colour back panel, slotted into grooves in the box the same way |
| Back rails (wall cabinets) | ¾″ | Three solid rails across the back — top, middle and bottom — on either build; the wall screws go through these |
You pick which core the box is built from — plywood (PW) or particleboard (PB) — and that single choice is what decides which back-panel row above applies to your kitchen. Almost everything else is the same either way: the same ¾″ panel, the same melamine on both faces, the same matching PVC edge. The one other difference is how the box goes together — cam locks on plywood, screws on particleboard.
Three things in that table matter more than they look. Melamine on both faces means the panel is sealed inside and out, so there is no raw board waiting to drink up a spill — and it is why the cabinet interiors are finished rather than bare. PVC edge banding in a matching colour is the detail that separates a box that still looks new in ten years from one with swollen, chipped front edges: on a frameless cabinet that banded edge is the visible front of the carcass. And the ¾″ panel is what a hinge plate and a drawer runner screw into — thin sides are where cheap cabinets fail first.
Why only the drawer’s bottom and back are board: the drawer’s sides are the runners. A modern drawer box is built from a steel drawer-side system — the metal side wall and the undermount slide are one engineered part — and the 16 mm panels drop into it to form the floor and the back. That is why a drawer pulls all the way out without sagging, and why the drawer box is far stronger than four bits of board screwed together.
The back panel is ⅛–¼″ thin — it carries nothing. What holds a loaded wall cabinet on the wall is the three solid ¾″ rails across the back of every wall cabinet — top, middle and bottom. Your mounting screws go through those and into a stud. A screw driven through the thin back panel alone is holding onto 3 mm of board and a promise.
North-American cabinets come two ways. A framed cabinet has a solid wood frame across the front of the box; the door sits on or in that frame. A frameless (European) cabinet has no frame — the ¾″ box edge is the front, and the door covers the whole thing (full overlay).
Frameless means bigger drawer boxes, easier reach, and a seamless modern look when cabinets sit side by side — at the cost of demanding a truly level install, because there is no frame to hide an out-of-square box behind. (That is why the install chapter is fussy about levelling.)
The worry is a fair one. With no face frame, the entire door hangs off a 35 mm cup bored into the door and a mounting plate screwed to the ¾″ side panel — there is no frame sharing the load. People reasonably ask whether that holds in particleboard.
It does, and the failures are worth naming because they are all avoidable. A modern European hinge is rated for tens of thousands of open-close cycles, and what gives out is almost never the hinge itself. It is an over-driven screw that stripped its hole (drive them snug, not hard — an impact driver on a hinge plate is how you ruin one), a tall or heavy door hung on two hinges when its height called for three, or water left sitting at a panel edge until the board swells around the screws. Get those three right and the doors will outlast the countertop.
And there is a real advantage hiding in the design: a concealed hinge is three-way adjustable and swaps out in about two minutes with a screwdriver. A drifted door gets a small turn of a screw — or a loosen, slide and tighten — instead of a repair; the finishing chapter walks through all three adjustments. A hinge mortised into a wooden face frame offers neither.
What they search at midnight “shaker vs flat panel cabinets” — style is taste; finish is durability. Decide them separately.
Two independent choices. First the style: a slab (flat) door reads modern and is the easiest to clean; a shaker (recessed panel) is the transitional default that suits almost any home; a glass front lightens a run of uppers. Then the finish, which is what actually wears:
On Flip cabinets the doors are full-overlay, so the door you pick covers the whole box — the colour and finish are almost the entire visual, which makes the next choice the fun one.
Those are the categories. Underneath them a door is a sandwich: a core board, a face layer, a back layer, and a band around the edge — and the thickness of each layer is the whole story of how the door will wear.
Flip doors come in three tiers — Classic, Delight and Grand. They are not three levels of the same door; they are genuinely different constructions and palettes.
| Tier | What is in it | How the door is built |
|---|---|---|
| Classic | Four flat doors — Matte White, Bianca Wood, Walnut, Rustic Oak | 0.02 mm melamine, colour and texture, on an 18 mm particleboard core |
| Delight | Glossy White (GW), plus the shaker styles — White Shaker, Grey Shaker, Slim Shaker White | GW is a 0.45 mm PET sheet on an 18 mm MDF core; the shakers are five-piece framed doors |
| Grand | The widest palette — matte and gloss solid colours, six wood textures (Vicenza, Kendal, Sahara and Natural Casella Oak, Light Tennessee Walnut, Natural Rossini Elm), and the much longer list of laminate decors behind More colors at the foot of the planner’s door-colour list | Matched solid colours and deep, realistic wood grain — the broadest choice in the range |
Glass fronts sit outside that table. There are three — White Shaker Glass, Grey Shaker Glass and Black Aluminum — and the planner lists them with the Grand colours, but they are not a colour for the whole kitchen: pick one and click the wall cabinets that should have it. They come in set wall-cabinet sizes.
The two specification sheets below are the ones people ask about most: the Classic door, and the Glossy White front from the Delight tier. If you want to know the exact panel or hardware brand behind a particular door, ask our team — a person will tell you. What the emissions line on a panel spec sheet actually means is unpacked here.
| Glossy White (GW) — Delight tier | Specification |
|---|---|
| Core | Medium-density fibreboard (MDF), 47–50 lb/cu ft, EPA Title VI compliant |
| Thickness | 0.71″ (18 mm) |
| Face | 0.45 mm PET (polyethylene terephthalate) laminate |
| Back | 0.02 mm white melamine laminate |
| Edge | 1.3 mm PVC banding, colour-matched |
| Behaves like | Moisture resistant, tolerant of acids and alkalis, wipes clean, high-gloss depth of colour |
| Classic series doors — Classic tier | Specification |
|---|---|
| Core | Particleboard, 41–44 lb/cu ft, EPA Title VI compliant |
| Thickness | 18 mm (about ¾″) |
| Face | 0.02 mm melamine laminate in the scheme colour and texture |
| Back | 0.02 mm melamine laminate |
| Edge | 1.3 mm PVC banding matched in colour and texture |
| Behaves like | Convincing wood grain and colour, hard-wearing, forgiving of fingerprints |
What to take from those two tables:
High gloss makes a small kitchen feel larger because it bounces light, and it is the easiest surface in the house to wipe — but a glossy surface shows fingerprints and dust, so it rewards a household that wipes down. Classic wears its texture, which is exactly what hides everyday handling, and it is the one that can look like wood without moving like wood. Neither fades, and neither needs refinishing.
Whichever face you choose, remember it is the same 18 mm door on the same 35 mm concealed hinge — so the hinge adjustment, the reveal and the install are identical.
Two-tone kitchens — crisp white uppers over a muted grey, sage or charcoal base — are the standout look of the moment, and they cost nothing extra: you are choosing two colours from the same catalogue instead of one. White shaker stays the safe evergreen, especially grounded with warm wood-toned floors, the pairing designers reach for most.
The practical trick: pick your colours against a real sample under your own kitchen light, not a screen — ask your Flip sales rep for door samples. Flip’s door and countertop colours can be tried together in the 3D planner so you see the actual combination on your actual layout before you commit.
What they search at midnight “quartz vs granite countertop” — for most DIY kitchens the answer is quartz, and here’s why.
| Surface | Upkeep | Notes |
|---|---|---|
| Quartz (engineered) | None — never sealed | Consistent colour, very durable; the low-worry default |
| Granite | Seal yearly | Natural stone, every slab unique; heat-tolerant |
| Laminate | None | Budget hero; modern patterns look far better than they used to |
| Butcher block | Oil regularly | Warm and repairable; keep it away from the sink |
Flip’s own countertops are engineered quartz: the countertop colours in the planner — the Clean, Essence and Signature series, plus More colors — are those slabs, and the quote prices the top from the same drawing.
Countertop templating and installation on stone is one of the jobs to hand to a pro — it is heavy, unforgiving, and the fabrication is specialised.
What they search at midnight “are soft-close hinges worth it” — yes, and they’re the cheapest upgrade that feels expensive every single day.
Flip cabinets ship with concealed European soft-close hinges as standard, so the “worth it?” question is already answered — your choice is mainly the handle finish that ties the room together. What those hinges and the drawer runners are actually doing — overlay, the 35 mm cup, the three families of slide — is a page of its own.
Not inherently. Dense, furniture-grade particleboard in a thick, fully-finished ¾″ panel makes a solid, long-lasting box — it is what most quality frameless cabinets use. The problem is thin, low-density board with raw edges. Judge the thickness and edge finish, not just the word.
Taste, not durability. Slab (flat) reads modern and is the easiest to wipe down; shaker is the transitional default that suits almost any home. Choose the style for looks, then choose the finish (painted, thermofoil, wood, laminate) for how it wears.
Different, not better. Thermofoil is a sealed skin that is seamless and very wipeable but dislikes high heat (keep it clear of ovens). Painted MDF gives the crispest colour and touches up if chipped. Both are excellent when made well.
Yes — it is the upgrade you feel every day for very little money, and it protects the doors and boxes from years of slamming. Flip cabinets include concealed soft-close hinges as standard.
Two cabinet colours in one kitchen — typically lighter uppers over a darker or warmer base, or a contrasting island. It adds depth for no extra cost and is the current standout look. Try the exact combination in the 3D planner before ordering.
A panel-ready dishwasher has a blank front built to take a door panel, so the machine disappears into the run. That panel is made to the appliance maker’s template, and Flip does not make panels for appliance doors — choose the model early and source its panel separately. A dishwasher end panel closes the open side of a dishwasher at the end of a run, where there is no cabinet beside it: in a Flip kitchen that is a ¾″ base end panel (MBEP) or the 3″-wide DWR3, ordered in your door colour with the cabinets. Fix one or two strips across the top of the opening, from the panel to the cabinet on the other side: they hold the panel in place and give the dishwasher’s mounting brackets something to screw into. Measure the opening height to the underside of the strips.
Boxes arrive with their working hardware — European concealed hinges with their mounting plates, undermount soft-close runners for the drawers, shelf pins, adjustable levelling feet and the fittings that put the box together (cam locks on plywood, screws on particleboard). Handles and knobs are the deliberate exception: pull style, finish and hole spacing are a design decision made alongside the door colour, and they are the very last thing to go on. Not in the box either: the screws that join one cabinet to the next and the screws that fix them to the wall — those are yours to buy. If you have Flip assemble the boxes — an extra-cost option to ask for with your quote — only the box itself is built; the legs and hardware come packed in a box for you to fit.
About 1½″ past the face of the base cabinet — that is a 25½″ deep top on a 24″ box, which is why fabricators quote 25½ or 26″. It covers the door faces and lets drips fall clear of them. On the seating side of an island you want 15″ of knee room at a 36″ counter (12″ only at a 42″ bar). A ¾″ quartz top carries 6–10″ unsupported, never more than half the depth of the cabinet below, so past 10″ you need brackets or a support panel underneath — your fabricator has the final say.
You can, but ask first whether you need to. Cabinets come in 3″ width steps and a filler closes anything up to about 3″ — so cutting is for the case a filler genuinely cannot solve. Reducing a base cabinet’s height is the easy one. Reducing its width means cutting the box and the back and the door, then re-boring the hinge cups — possible with a table saw and patience, but you are now a cabinetmaker. Whichever you cut: score the line, tape both faces and use a fine-tooth blade, or melamine will chip along the cut.
The sides, shelves and bottom are ¾″ (18 mm) plywood or particleboard, finished with creamy-white melamine laminate on both faces and PVC edge banding in a matching colour. Drawer bottoms and backs are ⅝″ (16 mm) in the same construction. Being sealed on both faces is what keeps the interiors finished and keeps a spill out of the board.
No — and it is not meant to be. The back panel is only ⅛″ (3 mm) plywood or ¼″ (5 mm) particleboard, slotted into grooves in the box. The strength is in the three solid ¾″ rails across the back of every wall cabinet — top, middle and bottom. Drive your mounting screws through those rails into a stud, never through the thin back alone.
A door with a 0.45 mm sheet of PET (polyethylene terephthalate) laminated onto an MDF core, with a white melamine back and 1.3 mm colour-matched PVC edge banding. Because the face is a genuine sheet rather than a thin printed skin, it gives a deep gloss and stands up to moisture and household acids and alkalis — and it wipes clean in one pass.
A melamine door is a resin-impregnated laminate bonded to a board core — on Classic series doors, a 0.02 mm melamine layer in the scheme colour and texture over an 18 mm particleboard core. Modern versions carry a real embossed grain and the edge banding is matched in texture as well as colour, which is what stops a wood-look door giving itself away at the edges.
Look at density rather than the name. The MDF used in high-gloss fronts runs 47–50 lb/cu ft against 41–44 lb/cu ft for the particleboard in Classic doors, so it machines a crisper edge, grips a screw harder and feels heavier. Particleboard doors are lighter and take a textured wood-grain finish beautifully. Both are stable and neither will fade.
It is the North-American limit on formaldehyde emissions from composite wood panels — particleboard, MDF and hardwood plywood. A panel described as EPA Title VI compliant has been certified against that standard. It says nothing about strength; it is about the air in your kitchen, and it is worth asking any cabinet supplier to confirm.
They are different constructions, not just different prices of the same door. Classic is four flat doors — Matte White, Bianca Wood, Walnut and Rustic Oak — built as 0.02 mm melamine, colour and texture, on an 18 mm particleboard core. Delight holds Glossy White, a 0.45 mm PET sheet on an 18 mm MDF core, along with the shaker styles. Grand is the widest palette: matte and gloss solid colours plus six wood textures. Glass fronts are not a tier of their own — the planner lists its three glass doors with Grand, and you put them on the individual wall cabinets you choose.
The sides are steel — the metal drawer side and the undermount runner are one engineered part — and the bottom and back are 16 mm (⅝″) panels in the same melamine-faced, PVC-banded construction as the cabinet. That is why a full-extension drawer carries real weight without sagging, and why there is nothing to come loose the way a four-sided wooden box does.
