What Size Integrated Dishwasher Do I Need? A Measurement Guide

If you’re planning a kitchen upgrade or replacing an old unit, knowing what size integrated dishwasher you need is essential. Get it wrong, and you could end up with costly fitting issues or appliances that don’t match your kitchen layout. This guide covers standard sizes, how to measure correctly, and key things to look out for before you buy.

Standard Sizes of Integrated Dishwashers

Integrated dishwashers typically come in three size categories: full-size, slimline, and compact. Here’s a quick breakdown:

Type	Width	Height	Depth	Capacity
Full-size Integrated	60cm	82–87cm	55–60cm	12–16 place settings
Slimline Integrated	45cm	82–87cm	55–60cm	9–11 place settings
Compact/Tabletop	55cm	45cm	50cm	6 place settings

How to Measure Your Space

Before choosing a dishwasher, measure your available space carefully. Here’s how:

Use a tape measure to record the width between the inside edges of the cabinet.
Measure the height from floor to underside of the worktop, accounting for levelling legs.
Check the depth, remembering to include any skirting or pipework at the back.
Use a spirit level to ensure the floor is flat, as uneven floors may affect installation height.

Allow a few mm of clearance on each side for fitting and ventilation, especially around the back.

Built-In vs Fully Integrated vs Semi-Integrated

Here’s how different integrated dishwasher types affect size and fitting:

Fully integrated: Completely hidden behind a cabinet door; standard dimensions apply.
Semi-integrated: Control panel remains visible; depth may vary slightly.
Built-in: May refer to any under-counter unit that fits into cabinetry, not always fully concealed.

Key Considerations Before You Buy

Plumbing and electric clearance: Ensure easy access for water inlets, waste and plug socket.
Cabinet door size: Match the height of your door panel with dishwasher fascia.
Hinge clearance: Watch for adjacent drawers or doors that may block dishwasher opening.
Flooring height changes: If your kitchen floor is raised, it could reduce installation height.

Common Installation Pitfalls

Worktop too low or high for the dishwasher to slide under
Cabinet door misalignment due to wrong height or hinge issues
Insufficient depth, causing dishwasher to stick out
Incorrect plinth cut-out obstructing the lower door swing

Frequently Asked Questions

Most full-size integrated dishwashers need a 60cm wide cabinet. Slimline models typically fit into a 45cm wide space.

While most models follow standard sizing (either 60cm or 45cm wide), height and depth can vary slightly. Always check the specifications before buying.

Most integrated dishwashers are around 82–87cm tall to fit under a standard worktop. Adjustable legs help level the appliance during installation.

Yes, but you’ll need suitable cabinetry to accommodate the appliance and a matching door panel. Professional installation is often recommended.

Not quite. Most are 55–60cm deep, but be sure to allow extra space at the back for water and electrical connections.

A fully integrated dishwasher is completely hidden behind a cabinet door. “Built-in” is a general term and may also refer to semi-integrated units with visible controls.

It’s possible if you’re confident with plumbing and cabinetry work, but mistakes can lead to misalignment or leaks. Many choose to hire a professional installer.

Final Verdict: Which Dishwasher Is Right for You?

Choosing the right size integrated dishwasher depends on understanding the available space and knowing which model suits your household’s needs. Always measure carefully, check product specs, and consider hiring a professional if unsure. A well-fitted dishwasher not only performs better but blends seamlessly with your kitchen design.
