What is a modular kitchen and what materials and types are used?

A modular kitchen uses pre-made cabinet units. These are cut in a factory and put together on site. A traditional kitchen is built part by part. A carpenter works at home with solid wood or site-cut plywood.

Traditional kitchens often have no fixed board grade or finish. Each piece is cut and joined on site. The hardware depends on what the carpenter can find locally.

Ask whether the studio's units are made in a factory or cut on site. Factory-made units usually fit better and finish more evenly, since machines do the cuts and edge banding.

Modular kitchens cost more mainly because of the boards, the branded hardware and the finish, not just labour. Factory-cut BWR or BWP plywood and HDHMR board add cost. So do soft-close hinges, drawer channels, and laminate, acrylic or PU finishes. These all show up as line items on a quote.

A separate answer on this site gives a full breakdown of cost per square foot. Another answer covers whether the extra cost is worth it compared with a carpenter-built kitchen.

• Ask for the hardware brand and model by name, not just "branded hardware"
• Ask for the board grade by name, for example BWR plywood to IS 303 or HDHMR, not just "ply"

No single material suits every cabinet. The right choice depends on where it sits in the kitchen. MDF, made to IS 12406, has a smooth surface that takes paint well. But it swells when wet, so it suits painted shutters, not base units near water.

BWP (marine) plywood, made to IS 710, resists boiling water and repeated wetting. This makes it the right choice for sink units and other wet areas. HDHMR board is dense and handles splashes well once its edges are sealed. It costs less than plywood but more than MDF, and works well for shutters and general cabinets.

The comparison table on this page sets these three side by side. The plywood-for-kitchens answer covers plywood grades in more detail. The MDF glossary entry explains that material further.

• MDF (IS 12406): smooth, paints well, swells when wet, suited to painted shutters
• BWP (marine) plywood (IS 710): very high moisture resistance, suited to sink units and bathrooms
• HDHMR board: dense, good moisture resistance, medium cost, needs sealed edges and support on long shelves

Laminate and acrylic are the two common finishes applied over cabinet boards. They are not materials in themselves. Laminate, made to IS 2046, resists scratches well, wipes clean easily and costs less. This suits most kitchens and wardrobes.

Acrylic gives a high-gloss, mirror-like look. It shows fine scratches more easily and costs more than laminate. It suits shutter fronts where a glossy finish matters more than low upkeep.

Granite, quartz, marble and stainless steel are countertop materials commonly seen in the market. InteriorIQ's cost data for these sits on the price pages, not here. Check the quotation checklist on this page to confirm the finish sheet's thickness and brand are named on the quote.

Straight, L-shaped, U-shaped and parallel layouts are the common modular kitchen designs. The choice depends on the room's size and shape, not on one layout being better than the rest.

Water handling depends on the board chosen. BWP plywood and HDHMR board resist moisture well. Plain MDF and particleboard swell when they get wet. Longevity also depends on edge banding covering every exposed edge, and on using the correct hardware. Both are covered in the carcass and shutter stages of the checklist on this page.

Inspect the edge banding closely around the sink cabinet when the kitchen is installed. This is the most common point where water gets in and damages the board underneath.

• Straight: fits narrow kitchens or single-wall layouts
• L-shaped: fits corner spaces, common in mid-size apartments
• U-shaped: fits larger kitchens with more counter space
• Parallel: fits galley-style kitchens with two facing walls
