How to choose a corner wall unit


When designing your new kitchen, the corner can be one of the most difficult areas to plan, especially when it comes to which corner wall unit to use and how they fit in with the units next to them and corner posts.

The article below will give you a few options to choose from, as well as considerations to make before deciding upon the corner wall unit that is right for your new kitchen layout.

Standard corner wall units

If you are using one of the standard corner wall units, where a 300mm blanking panel is used to butt up against the unit on the adjacent run then you are going to need a 30x30mm wall corner post to cover the gap left in the corner, after you have placed the unit 30mm from the wall, to allow the door on the corner wall unit to open.

The 30mm gap from the wall  also allows your wall units to line up with the 70x70mm corner post that is required for the corner base unit below it.

A few useful bits of information to remember here are:

  • A corner wall unit blanking panel is always 300mm wide
  • A corner base unit blanking panel is always 500mm wide.

The 2 images below show examples of a wall corner post that has been used to fill the gap between 2 wall units. The wall corner post is made using cut down bits of filler panels in door material.

L-shaped or angled corner wall units

When using an l-shaped corner wall unit (600mm x 600mm), no wall corner post is required, as the doors open up in the area where the corner post would be.

Some people use angled or l-shaped corner wall units to negate the need for a wall corner post but using these units would require that your service void on your corner base unit be reduced to 100mm from 130mm, to give a 40x40mm corner post on the base unit, so that 600mm was achieved to keep the wall and base units lined up. A base unit is 560mm deep + 40mm corner post = 600mm (the same size as the l-shaped corner wall unit 600mm x 600mm).

If you had a 70mm x 70mm base unit corner post then it would be 30mm too wide for the wall unit to line up, as shown below.

40mm x 40mm base corner post

When using an l-shaped corner wall unit, in order to get the corner base unit to line up below it, so that the doors are directly in line with each other, the corner post for the base unit below it needs to be 40mm x 40mm. Please be aware that a smaller corner post can increase the possibility of handles clashing.

If using an l-shaped 600mm x 600mm corner wall unit, to help keep base units lined up below, it would be ideal to use a 900mm x 900mm l-shaped corner base unit as well, as shown below.
