What is Sliding Wardrobe Casing and Why Should I Choose it?

October 2025

We offer casing which is used as a wardrobe lining for designing and building your sliding wardrobe or as a ‘false wall’ if you need an end panel. As you design your wardrobe using our state of the art 3D design tool, you will see the different casing options to choose from. For all orders we strongly recommend casing all sides and casing on all sides must be selected if your order is to be installed by My Sliding Wardrobe.

The options vary depending upon your selections and include:

Casing is generally added to orders for one or more of the following reasons,

If you have carpet – As track cannot be fitted straight to carpet, casing is always required under the bottom track. Casing can be fitted straight to the carpet or it can be fitted to the floor and the carpet fitted up to it, but either way, if there is a carpet, there must be base casing.

If you have opted for a triple track – Standard casing for floors, ceilings and walls is 87mm deep which is perfect for our standard double track system, however if you opt for a triple track system and require casing, this casing must be 130mm deep. The easiest way to make the casing deeper is to order in the normal way with casing and then contact us after you have ordered so we can make the adjustment for you.

Dealing with skirting or other wall finishes – For most customers, some skirting board and other wall finishes such as picture rails, dado rails or coving need to be removed to allow their sliding doors to close against the wall. Casing makes this easy as just an 87mm or 130mm section (depending on your casing type) needs to be removed and the casing is inserted in that gap from floor to ceiling. This hides any untidy wall behind the skirting and makes the process quick, easy and neat.

Where your walls are not straight or plumb – If your walls are not plumb or straight, the casing can easily be fitted and packed accordingly to give a straight and plumb surround for the track and doors. Without this, there would be gaps when the sliding doors are closed against the wall.

Where your ceiling and floor are not straight or level – If your floor and / or ceiling is not level or straight, the casing can easily be fitted and packed accordingly to give a straight and level surround for the track and doors. This is particularly important of the floor as bottom track cannot be packed without casing and all of the weight of the doors is on the bottom track.

If the floor finish will be fitted after the sliding doors – If you are planning to have a floor finish fitted after the sliding doors, it is almost always advisable to have a casing board underneath the bottom track, raising it off the floor 18mm, allowing the new floor finish to be fitted up to the casing board both outside and inside the wardrobe.

Avoiding closing doors on the wall – Most customers don’t like to have their sliding doors close against the painted plaster wall and so casing allows the doors to close against woodwork in one of 10 colours. Sliding doors can last up to 20 years and so it is important they are closing onto something rather that the wall.

It may be cheaper – Casing boards are 18mm thick which means they can reduce the width and height of the doors, which can in turn prevent the doors from being in a more expensive price category.

Aesthetics – Casing can look really good as it frames the sliding wardrobe in a colour of your choice, giving a small boarder around the sliding doors. Many customers order casing for this reason alone.

Where there is a requirement for an end panel – If your opening space doesn’t sit between 2 walls and either requires 1 end panel and a wall or 2 end panels to function, you will be ordering casing as end panels are a type of casing. We offer 2 sizes of end panel – 640mm deep and 900mm deep and you can select which you want when you select the casing colour. The majority of customers will not need the 900mm deeper end panel.

Some people think of casing as an added extra and whilst this is true, it can also be vital for use to correct issues with the opening space, making it simpler, quicker and neater to build your perfect sliding wardrobe. Casing is also easy to install and gives you not only an aesthetic benefit, but practical benefits too as outlined in this blog. Our casing is all 18mm thick by 2800mm long and consists of 2 different component types:

  • 87mm standard or 130mm deeper liner casing boards used for floor, ceiling and walls
