The Importance of Wall Unit Depth

When planning your dream kitchen, the depth of your wall units can significantly impact the overall look and functionality of your space.

The standard depth for UK kitchen wall units is 300mm, excluding the door thickness.

Additionally, considering the depth of a wall unit is pivotal when incorporating appliances, such as ovens, microwaves or other kit, into your design.

Deep units are necessary to accommodate these appliances whilst maintaining a seamless look to your kitchen design. 

One might ponder if it's possible to customise the depth of standard wall cabinets.

Typically, most brands offer standardised depths but do keep an eye out for brands providing custom cabinets and bespoke options if you have specific requirements.

Remember, while the standard depth suits most kitchens, don't hesitate to adapt according to your needs and preferences. Your kitchen should not only be elegant but also practical and tailor-fitted to your lifestyle.

Considering Door Thickness: A Factor to Remember

When designing your kitchen, the thickness of the cabinet doors is a detail that must not be overlooked.

Observe that the standard kitchen cabinets depth of 300mm doesn't include the door thickness.

Thus, the overall depth of your cabinet structure will vary based on the thickness of doors you select. It's worth noting that door thicknesses can range between 15 to 22mm, depending on your chosen range.

The door thickness can impact not only on the aesthetic, but also on the functionality of the extra space.

Thick doors provide a robust and high-quality look, whereas slimmer doors can elicit a sleek, streamlined feel, fitting well in modern kitchens.

It does not merely stop at aesthetics, the door thickness can determine how much clearance you'll require when opening cabinets, particularly in narrow spaces or close to appliances.

To ensure your cabinet doors seamlessly integrate with your space, consider factors like your kitchen's layout and the placement of appliances. The door thickness also plays a role in the overall weight of the cabinet, potentially affecting wall support requirements.

If you want customisable options, you can choose doors ranging from thin, flat-panel designs to chunkier, shaker-style doors.

 Please keep in mind that there is no 'one size fits all', your personal preferences in form and aesthetics will determine which door thickness is suitable for your space.

Above-Sink Placement: A Practical Solution

For example, the lower 575mm units help you retain that cosy, snug atmosphere while the larger 900mm units work wonders in more spacious, lofty kitchens. 

Note: Keep an overhead clearance of at least 18 inches (456mm) between the countertop and the wall cabinet for comfortable functionality.
