How do I line up a kitchen mantle?


A question that we were recently asked regarding a kitchen mantle was, “I want to use the following setup.

  • 2120mm tall unit (with legs)
  • 720mm high wall unit
  • 1210mm high kitchen mantle
  • 720mm high wall unit
  • 2120mm tall unit (with legs)

But, the top of the kitchen mantle will be out of alignment by 10mm as my worktop is 30mm thick quartz. Can you advise on how to get all this to line up?”

The best solution

Well, the kitchen mantle is designed to work with 2120mm tall units, 720mm wall/base units and a 40mm thick worktop.

See the image below that shows the 2120mm measurement required for everything to line up with a 1210mm high mantle.

Mantle measurements

These measurements below all add up to 2120mm, the same as the tall unit wanting to be used.

  • 150mm legs on the base unit
  • 720mm base units
  • 40mm worktop
  • 1210mm kitchen mantle

But, as the customer’s worktop is thinner (30mm thick), the other 10mm will need to be achieved by raising the mantle or by placing a thin piece of colour matching filler at the top.

No tall units solution

If no tall units are being used in the kitchen run, then you can simply lower the wall units by 10mm to get the mantle to line up correctly.

Custom size kitchen mantle

If you require a custom size mantle then we can make the mantle higher or wider (only in 100mm increments) but you will have to add a note to the order advising the height, for every 100mm there is a £100 surcharge.

    What is the ideal range cooker size under your standard mantles ? I am hoping to use a 900mm range

    • DIY Kitchens says:

      Hi, the internal width of our mantles is 1200mm and the 2 x 300mm wide usable units, each side of the mantle, will sit on your worktop. A 900mm range cooker would work absolutely fine.

      Hi, yes this is fine, if it is over the £750 minimum order limit.

    We would like to position a mantle over our 1000mm cooker, but do not have room on the worktop for the 300mm cupboards either side. Is it possible to order just the top section of the mantle including arch, shelf and cornice so it can act as a bridge between abutting wall cupboards above the cooker?

      Hi, i’m afraid our mantle is a 1 piece unit. If you contact our sales team on 01977 608 418 then they would be able to advise if there are ant workarounds?

    How is the mantle secured to the wall?

      Hi Justin, you would need to use L brackets to fix the mantle to the wall, at the top.

    Hi there,

    We have purchased the DIY Kitchen mantle and have had it made 200mm wider and 200mm higher. We are wanting to put a mirrored splashback in. I believe the width of the splashback should be 1400mm, but could we ask what would be the most appropriate height would be (as you wouldn’t want people to see the wall above the splashback when you’re cooking)?

    Also, are we correct that it’s best to install the mantle first and then the splashback?

    Thank you,

    • Diy Kitchens says:

      Hi Jack, the internal dimensions of your mantle will be; 1400mm in width as you previously mentioned. However, the internal height remains the same as a standard mantle at 905mm. I would advise the splashback to be fitted first, as the internal height at the front of the mantle is smaller at 705mm.

    In desparate need of some advice please.
    Have recently purchased a new kitchen and would like to buy a ready made mantel to fit in and around. Some questions, sorry.
    Do ready made mantels come in standard sizes?
    Do you provide fitting?
    Would the mantel accommodate an extractor fan?

    Sorry working on a tight deadline so any advice would be extremely welcome.

      Hi Rob,

      The dimensions of the mantle are 1800mm wide and 1200mm for the internal width of the mantle as there are 2 x 300mm units either side built into it. The sales team can amend the width of the mantle in 100mm increments but it would incur a surcharge of £100 per 100mm change.

      The underside of a mantle is hollow to allow you to install a canopy extractor.

      The standard mantle on our website in Linwood Oak is £974.98.

      We are a supply only company and only deliver the items to your home, we do not do any fitting I’m afraid.

    Can you make narrower mantles?

    July 23, 2018 at 11:54 am
    • Diy Kitchens says:

      Hi Paul, yes, we are able to do this on request. Please just add this to the note on the item in your basket.

    (Q) We have an existing fireplace which will be hollowed to take a range oven. The width of the firestack is 1500mm and depth is 380mm. Because the mantle is 1800mm wide I wonder whether it is possible to cut out the back of the mantle so it “wraps around” the existing firestack?

    June 22, 2018 at 7:45 am
    • Diy Kitchens says:

      Hi Matt, the mantle is 1800mm overall but the internal dimension is only 1200mm as the two units either side are 300mm wide so this would not be wide enough to cover the chimney that you have.
      You may wish to look at using pan drawer frontals to create a mock mantle framing –

      For example 2 x 800 x 283/355 drawer fronts for top panel = 1600mm

      2 x 800/900/1000 x 283/355 pan drawer fronts for side panels depending on how high you want the mantle top section to sit

    (Q) On the underside of the mantle, is it a solid piece of wood or hollow where I’d put the extractor fan?

      Hi, The underside of a mantle is hollow for extractors.

    You could also raise base units by 10mm and make your own 160mm plinths using filler / end panels.
