Slimline Dishwashers – 45cm Integrated & Freestanding Models
Shop slimline dishwashers in the 45cm width class, including fully integrated and freestanding models. Compare place settings, exact dimensions, energy class, noise level, cutlery storage and drying systems to find a narrow dishwasher that fits your kitchen without moving up to a standard 60cm appliance.
How to choose a slimline dishwasher
The main advantage of a slimline dishwasher is its narrower width. Current models are designed around a nominal 45cm installation rather than the approximately 60cm width of a standard full-size dishwasher.
Width is only one measurement to check. Compare the exact appliance height, width and depth, the available cabinet or floor space, water and waste connections and the clearance required for the door to open.
| What to compare | Why it matters |
|---|---|
| Installation type | Choose between fully integrated models that require a kitchen furniture door and freestanding models with their own finished exterior. |
| Place settings | Shows the nominal loading capacity and helps compare different 45cm models. |
| Exact width | Models sold as 45cm are normally slightly narrower than 450mm so they can fit the appropriate opening. |
| Cutlery storage | A cutlery tray creates a separate loading level, while a basket uses space within the lower rack. |
| Energy class | Allows comparison using the current A to G dishwasher energy scale. |
| Noise level | Worth comparing in open-plan kitchens or where the dishwasher will be run during the evening. |
Integrated or freestanding slimline dishwasher?
Integrated slimline dishwashers
A fully integrated 45cm dishwasher is installed within fitted kitchen cabinetry and normally sits behind a matching furniture door. The appliance controls are positioned along the upper edge of the dishwasher door and are concealed when the door is closed.
Check the required cabinet aperture as well as the permitted furniture-panel dimensions and hinge system. Different manufacturers use different furniture-door arrangements, so replacing one 45cm integrated dishwasher with another does not automatically guarantee that the existing kitchen panel will fit.
Freestanding slimline dishwashers
A freestanding slimline dishwasher has its own finished front and does not require a matching kitchen door panel. This can make it a practical replacement where a narrow freestanding appliance is already installed.
It still needs suitable water, waste and electrical connections as well as sufficient space for the appliance and its open door. Check the exact height as freestanding models can be taller than integrated machines designed for installation beneath a worktop.
How wide is a slimline dishwasher?
Slimline dishwashers are normally described as 45cm appliances, but the physical width is usually slightly below 450mm. Current models in this category measure approximately 446mm to 448mm wide.
Use the manufacturer's exact millimetre dimensions before ordering. Do not assume that a nominal 45cm description alone confirms compatibility with an existing cabinet opening.
9 or 10 place settings?
Most current slimline dishwashers accommodate around nine place settings, while selected models provide ten. The additional place setting can be useful, but basket design often matters just as much as the headline capacity.
Consider the types of items you wash regularly. Height-adjustable upper baskets, folding supports, glass holders and flexible cutlery storage can make it easier to accommodate pans, large plates and awkward utensils within the narrower cabinet.
Cutlery tray or cutlery basket?
A separate cutlery tray places cutlery and utensils on an upper loading level. This can free space in the lower basket and keep individual pieces separated during washing.
A removable cutlery basket sits in the lower rack. It is simple to remove when unloading and may suit households that prefer a more conventional basket arrangement.
Neither system is automatically better. Compare how much lower-basket space you need for plates, pans and larger cookware.
Energy-efficient slimline dishwashers
Dishwasher energy labels use the current A to G scale. Compare the energy class together with electricity consumption per 100 ECO cycles and water consumption per ECO cycle.
A narrower dishwasher can use less water per cycle than some larger machines, but it also holds fewer place settings. For a meaningful efficiency comparison, consider consumption alongside capacity and how often the appliance will need to be run.
Quiet slimline dishwashers
Compare the manufacturer's stated airborne noise figure if the dishwasher will be installed near a living or dining area. Current slimline models vary meaningfully in noise output, so use the dB specification rather than assuming every compact dishwasher is equally quiet.
The decibel scale is logarithmic, which means a small numerical difference should not be treated as a simple percentage change in perceived loudness.
Automatic door-opening drying
Several current 45cm dishwashers use automatic door opening towards the end of the programme to allow moist air to escape. AEG calls its system AirDry, Miele uses AutoOpen and selected Smeg models use Dry Assist+.
The principle is similar, but programme compatibility and the exact opening behaviour vary by model. For integrated appliances, follow the manufacturer's furniture-panel and installation requirements so the automatic-opening system can operate correctly.
Glassware and delicate items
Selected slimline dishwashers include dedicated supports or programmes for delicate glassware. These can help secure stems and reduce movement during washing, which is particularly useful when the narrower basket needs to accommodate mixed loads.
For example, selected AEG GlassCare models use SoftGrips and SoftSpikes to hold glasses more securely, while Miele models include dedicated glass-care programmes and loading features.
Installing a 45cm integrated dishwasher
Check the cabinet width, height and depth as well as the dishwasher's exact dimensions. Also confirm the furniture-door size and weight, hinge arrangement, plinth clearance and the position of the water, drainage and electrical connections.
Some current slimline integrated dishwashers use sliding furniture-door systems. These can help accommodate particular furniture-panel and plinth arrangements, but the installation method is model specific and should be checked in the manufacturer's installation drawing.
Slimline dishwasher FAQs
What is a slimline dishwasher?
A slimline dishwasher is a narrow dishwasher designed around a nominal 45cm width rather than the approximately 60cm width of a conventional full-size model.
How wide is a 45cm dishwasher?
The actual appliance is normally slightly narrower than 450mm. Current products in this category measure approximately 446mm to 448mm wide, so always check the exact specification before ordering.
Are slimline dishwashers available as integrated and freestanding models?
Yes. Integrated models sit within fitted kitchen cabinetry and require a suitable furniture door, while freestanding models have their own finished exterior.
How many place settings fit in a slimline dishwasher?
Current models commonly provide nine place settings, with selected 45cm dishwashers accommodating ten. Basket layout and adjustment also affect how much everyday cookware can fit.
Is a slimline dishwasher suitable for a small household?
It can be a good choice where kitchen width is restricted or normal dishwasher loads are smaller. Larger households should consider whether the lower capacity would mean running more frequent cycles than with a 60cm dishwasher.
Can I replace any old 45cm dishwasher with a new 45cm model?
Not automatically. Compare exact height, width and depth as well as installation type, furniture-panel dimensions, hinge system and plumbing connections before ordering a replacement.
What is the difference between a cutlery tray and basket?
A cutlery tray uses a separate upper loading level, while a basket occupies space in the lower rack. A tray can free lower-basket room, while a removable basket can be quicker to lift out and unload.
Do slimline dishwashers open automatically after washing?
Selected models do. AEG AirDry, Miele AutoOpen and Smeg Dry Assist+ are examples of systems that open the dishwasher door towards the end of the programme to support drying.
Are slimline dishwashers less efficient than full-size dishwashers?
Not necessarily. Compare the energy label, electricity and water consumption and place-setting capacity of the individual models. A smaller appliance may use less per cycle but may also need to run more often if household loads are large.
Where can I compare 60cm dishwashers instead?
Browse all dishwashers if you have enough space for a standard-width model and want to compare the wider range of installation types and capacities.
