Kitchen Renovation Guide: Cabinets, Countertops, Layouts and Real Costs

Planning a kitchen renovation but unsure where budget actually goes? Start with the system, not the style. Kitchen renovation is a coordinated system of kitchen cabinets, countertop, layout and services that must handle moisture, heat and daily load together. Map those four first, then pick finishes. This guide shows you how.

What Is Kitchen Renovation and How the System Fits Together

Kitchen renovation is the renewal of the storage, work surface, circulation and service zones of a kitchen so that kitchen cabinets carry load without sag, countertop resists heat and stains, and layout keeps the sink-cook-fridge triangle at 120 to 270 cm per leg.

Think in four subsystems. Base and wall cabinets store and carry. Countertop provides a heat and water resistant work plane. Layout defines movement. Services (plumbing, power, exhaust) make the first three durable. Fail one, the others suffer.

A full renovation replaces carcass, countertop, backsplash and services. A partial refresh keeps a solid carcass and swaps door fronts, countertop and hardware. Choose full when the plywood base has swollen at edges or hinges no longer hold. Choose partial when structure is sound and you need a look and workflow upgrade.

In small 2×3 m kitchens, a full gut often adds only 15 to 20 percent cost over a partial, because aligning old and new levels takes extra labor. Photograph the existing cabinet interior at hinge height before deciding.

How the Cabinet System Works: Carcass, Edge Sealing and Hinges

Kitchen cabinets fail at edges and hinges first, because plywood and particleboard cores swell when edge sealing is thin or broken, and a 60 kg loaded drawer then pulls its installation screws.

A standard carcass uses 15 to 18 mm plywood or blockboard for sides, 8 mm back panel in a groove, and 1 mm ABS edge banding on every cut. Skip the back panel groove and the box racks under load within a year.

Hinges carry the door. A 110 degree soft-close hinge rated at 35 kg per pair holds a 700 mm high door with glass for years. Use three hinges per door when height exceeds 900 mm, and mount into plywood, not particleboard, at the screw zone.

Edge sealing matters more than wood species. A 0.4 mm PVC band looks finished but lets vapor creep at the 90 degree joint. A 1 mm ABS band with PUR glue keeps the joint sealed after 500 steam cycles from a rice cooker.

Field check: open a base cabinet near the sink. If the bottom edge feels rough or shows dark lines, moisture has entered the core. Budget to replace that carcass instead of wrapping it.

Layout Decisions: L-Shape, U-Shape and Galley with Real Workflow

Layout determines whether a kitchen renovation feels spacious or cramped, because the same 6 m2 can give 3.2 m of counter or only 2.1 m depending on circulation and corner treatment.

An L-shape suits 2.5 to 3.5 m walls, gives a clear 90 to 120 cm aisle and keeps the window wall open for a sink. A U-shape needs at least 2.4 m width between walls to keep a 100 cm aisle after 60 cm deep cabinets on both sides.

A galley with two parallel runs works when the door is at the end, not the side. Keep the main run at 60 cm depth and the secondary at 45 cm if the total width is below 2.2 m.

Respect the work triangle. Sink to cook 120 to 210 cm, cook to fridge 120 to 270 cm, sink to fridge 120 to 210 cm. Shorter creates collisions, longer wastes steps. Measure after cabinets, not wall to wall.

Example: a 3 x 3 m room with a window on one side. L-shape with a 60 cm base + 60 cm tall pantry at the end often beats a U-shape that blocks the window with a wall cabinet. You gain 0.8 m of usable counter and keep natural light on the prep zone.

Material Choices Compared: What Lasts, What Swells, What Costs

Kitchen cabinets in plywood with 1 mm ABS edge handle humid tropical kitchens better than particleboard with thin banding, while countertop in 20 mm quartz beats 18 mm laminate on heat and stain when the cooktop is close.

Laminate on particleboard is light and budget friendly at Rp 1.2 to 1.8 million per meter, but swells at cut edges if the seal fails. Plywood + HPL at Rp 1.8 to 2.8 million per meter adds moisture resilience. Quartz at Rp 3.5 to 5.5 million per meter gives a non-porous slab that resists turmeric and 180 degree pan heat.

Drawer hardware matters as much as board. A 45 cm deep drawer with undermount slides rated at 30 kg keeps alignment after 50,000 cycles. Side-mount ball slides at 20 kg sag when loaded with pots and cast iron.

Do not mix a heavy stone slab with a thin 15 mm particleboard carcass. The 20 kg per linear meter slab load will rack the box unless you upgrade to 18 mm plywood and add a 30 mm aluminum rail at the front.

*With 18 mm plywood carcass and front rail. Particleboard carcass drops quartz system to 25 kg safe load.

Honest trade-off: laminate is easiest to reface in three years, quartz is hardest to modify once templated. Choose laminate if you rent or expect layout change, choose quartz if you cook daily and keep layout for eight plus years.

Budget, Maintenance and When to Call a Professional

Budget per m2 for a mid range kitchen renovation in Indonesia runs Rp 4.5 to 8 million per linear meter including kitchen cabinets, countertop and basic plumbing and electrical, or Rp 2.8 to 4.5 million per m2 of floor area for a full system.

Break it down. Cabinets 50 to 60 percent, countertop 20 to 30 percent, backsplash and services 15 to 20 percent, hardware and lighting 5 to 10 percent. Isolate each in the quote to spot a cheap board hiding expensive hinges.

Maintenance is simple but regular. Wipe spill at edge banding within minutes, not hours. Clean soft-close slides with a dry brush every six months. Check sink cabinet base quarterly for darkening.

Call a professional when plumbing moves more than 30 cm, when a load bearing wall is touched for an open plan, or when gas and 3-phase exhaust are involved. A one day pro check is cheaper than a one week rework after a leak.

Decision Guidance: Choose L-shape with plywood + quartz if you cook daily in a humid space and keep the home five plus years. Choose galley with blockboard + HPL if you need maximum counter on a tight budget and can maintain edges. Choose a partial refresh if carcass passes the hinge and edge check.

Next steps: list your daily workflow, measure the triangle after cabinets, and request a separated RAB. Bring photos of cabinet interiors to the shop, not just Pinterest inspiration.
