How do I fill in a 225mm gap in a kitchen run?


A common question many people ask is how do they fill in a gap that is left between 2 units in a kitchen run.

Well, there is no definitive answer to this as there are a few options, which we have listed below.

Also, the examples below are based on having an extra 225mm of space left on a planned kitchen run. The size that you have will be different but the same principles apply.

(1) Replan your kitchen

It may sound like a harsh solution but have you looked at all the available units that are available? Our PDF kitchen planner shows you what kitchen units we currently make for our customers.

Take a look at the image below that shows a gap of 225mm that needs to filled somehow (130mm is now the recommended service void gap).

Kitchen Run 250mm Gap

Now look at the image below, by changing the 2 large 1000mm units to 2 x 1100mm units, you now have only 25mm to factor into your design.

The service void area, shown in green, would grow slightly to accommodate any additional space that needs to be concealed.

A bigger corner post would be needed, if concealing the extra space on the other run of units that would butt up to this one.

(2) Use small 150mm wide units

If you don’t want bigger units then go for slightly smaller ones instead and add in 2 x 150mm single highline kitchen units to fill in the extra space. We have swapped out the 2 x 1000mm kitchen base units and used slightly reduced width units that are 950mm wide. This gives you an extra 100mm of space, which gives 325mm in total.

325mm – (2 x 150mm) units leaves you with 25mm. 25mm /2 leaves you with 12.5mm that can be added to your service voids on either side of this run or added to the width of the corner post on the other run.

(3) Filler panels

If you feel that there are no other options available to you and there is no way to re-plan your kitchen then you can buy filler panels to help conceal any necessary gaps.

    Are the filler panels finished on all sides? i.e. looking at Norton Oak, these are 100×19; could the 19mm face be used to fill a 19mm gap or would you have to cut down the longer side?

      Hi, the filler panels on the Norton Oak are fully finished on both sides and all the edges as they are and oak veneer.
