How to Choose Kitchen Units — What the Showrooms Do Not Tell You

Rigid units arrive pre-assembled from the factory. Flat-pack units are assembled on site. Rigid units are structurally superior — they are built in controlled factory conditions with consistent glue lines and square corners. Flat-pack units are acceptable when assembled carefully, but quality is installation-dependent. For most residential kitchens, rigid units from a mid-range supplier outperform flat-pack units from a budget supplier at a comparable price point. The trade-off is delivery logistics — rigid units are bulkier and harder to carry into properties with tight staircases or small doorways.

The carcass is the box the doors attach to. The standard material is moisture-resistant MDF or chipboard (sometimes called E1 chipboard). Look for 18mm carcass boards — 15mm or less is a false economy on a kitchen that will take significant daily load. The interior finish matters too: a white melamine interior is cleanest and most functional. Bare chipboard or thin laminate interiors are a sign of corners being cut. For base units under sinks, specify solid material with an additional moisture-resistant coating or use a waterproof carcass entirely.

Yes, unreservedly. A soft-close hinge costs approximately £2-4 more per door than a standard hinge. Over the lifetime of a kitchen — typically 15-20 years — it prevents thousands of slams, protects door edges, and keeps alignment true. Every RCB kitchen specification includes soft-close hinges as standard. The same applies to drawer runners: undermount soft-close runners are worth every penny over side-mount budget runners, particularly on pan drawers with heavy loads.

Blum and Hettich are Austrian and German hardware manufacturers who produce the hinges, runners, and lift systems used inside kitchen units. They are not brands you will see on the door — they are the functional hardware inside the carcass. A kitchen supplier who specifies Blum or Hettich hardware is telling you something meaningful about their quality standard. Budget kitchens use own-brand hardware that may look identical but wears faster, loses alignment sooner, and is harder to adjust or replace. It is a legitimate quality indicator.

Painted doors (typically MDF primed and finished in Farrow and Ball or similar) give the most authentic, customisable result but are the highest maintenance — they chip on edges and require careful handling. Vinyl-wrapped doors are more chip-resistant but can delaminate around heat sources like ovens and dishwashers over time. Handleless slab doors in a high-pressure laminate or PET finish are extremely durable and easy to clean. For family kitchens with children, laminate or PET slab doors are our most-recommended option. Painted doors work best in low-traffic secondary kitchens or where the visual outcome justifies the maintenance commitment.

Floor-to-ceiling cabinets (typically run of tall housing units and bridging units that reach the ceiling) eliminate the gap at the top that collects grease and is nearly impossible to clean. They also provide more storage and a more contemporary look. The main constraints are ceiling height — standard 2400mm ceilings suit 2200mm tall housing units with a 200mm filler to ceiling — and cost. If budget is a constraint, prioritise tall housing units at each end of the kitchen run and use standard wall units in between rather than spreading budget evenly across all positions.
