Floor-to-ceiling doors are one of the simplest ways to make a room feel taller and more considered. Instead of a standard door with a strip of wall (and often a lintel and architrave) above it, the door runs all the way from the finished floor to the ceiling. Paired with a concealed frame, it can look almost like a moving section of wall.
This guide explains what full-height internal doors are, the main ways to achieve the look, and what to plan before you order, so the finished result looks as clean as the drawings.
What is a floor-to-ceiling door?
A floor-to-ceiling door, also called a full-height or ceiling-height door, is an internal door whose leaf fills the full height of the room. Standard UK internal doors are usually 1981mm or 2040mm tall, so in most rooms there’s a band of wall above a normal door. A full-height door removes that band.
Because the leaf is taller than any standard size, floor-to-ceiling doors are almost always made to measure. They’re usually flush (plain-faced) doors, which suits the minimal look, although panelled and veneered designs are possible.
Why choose full-height doors?
- A taller-feeling room. A continuous vertical line from floor to ceiling draws the eye upwards and makes the ceiling feel higher.
- A cleaner wall. No section of wall or architrave above the door means fewer lines and joints to look at.
- A bigger statement. In hallways with several doors, matching full-height doors give a calm, architectural feel.
- Hidden-door potential. Combined with a concealed frame and the same paint finish as the wall, a full-height door can almost disappear.
They aren’t right for every home. In a period property with deep skirting, cornicing and traditional panelled doors, a tall flush door can look out of place. They’re also a bigger investment than a standard door, as you’re paying for a bespoke leaf and a frame to suit.
Your main options
1. Full-height concealed doors (hinged)
This is the most popular way to get the look. A concealed, or flush-to-wall, door uses an aluminium frame that’s built into the wall and plastered up to, with hidden hinges and no architrave. Once decorated, all you see is a fine shadow line around the leaf.
Our Bespoke Concealed Door Set is made to measure up to 3m door height. It uses a 56mm solid core primed door slab, an extruded aluminium frame and 3D adjustable concealed hinges, and the frame can be installed in most partitions and load-bearing walls. Because the frame is hidden by plaster or plasterboard, it’s best to plan it at the wall construction stage.
For a deeper look at how these frames work, see our guide to concealed door frame details.
2. Full-height doors with a frame or lining
You can also have a tall door hung in a conventional lining with architrave. You lose the hidden-door effect, but it can suit more traditional schemes and can be simpler to fit into an existing opening. The head of the lining sits at or just below the ceiling.
3. Full-height pocket doors
If you want the height and the space saving, a floor-to-ceiling pocket door slides into the wall instead of swinging. Standard pocket door kits are designed around standard door heights, so a taller door generally needs a bespoke frame. Some manufacturers do offer bespoke frames for non-standard sizes, so ask before you plan around one. Also check the kit’s maximum door weight, because a taller leaf is heavier. Our pocket door kits, for example, are rated for door panels up to 60kg.
Browse our pocket door kits or read our pocket door sizes guide for more on how frame sizes relate to door sizes.
Hinges and weight: the technical bit
A taller door is a heavier door, and it puts more load on its hinges. A few principles are worth knowing:
- More hinges. Three hinges per leaf is normal for a standard door. Ironmongery guidance commonly recommends a fourth hinge for doors over 2100mm high. Very tall concealed doors may need more, so follow the manufacturer’s specification.
- Hinge capacity. Hinges are rated for a maximum door weight. Solid core doors are much heavier than hollow ones, so make sure the hinge set is rated for the actual weight of your leaf.
- Adjustability. Concealed 3D hinges can be adjusted in three directions, which is how a tall leaf is lined up perfectly flush with the wall.
- Stability. A tall, slim leaf is more prone to bowing than a short one, which is why full-height doors are usually solid core and properly sealed on all faces once painted.
If the door is a fire door, the hinges, number of hinges and their positions must match the fire door’s test evidence or certification. Don’t add or move hinges on a fire-rated doorset without the manufacturer’s approval. Our FD30 concealed doors guide explains more.
Planning and measuring
Full-height doors are less forgiving than standard ones. A 5mm slope in the ceiling is invisible over a normal door but very obvious along the top edge of a full-height leaf. Here’s what to check.
Measure to finished levels
The door has to fit between the finished floor and the finished ceiling, not the subfloor or the bare joists. Confirm the floor finish (tiles, engineered wood, carpet and underlay) and the ceiling build-up (plasterboard and skim) before you order. Our guide on how to measure for a concealed door walks through the process step by step.
Check the ceiling is level
Take height measurements at both sides and in the middle of the opening. If the ceiling or floor isn’t level, talk to your supplier and builder before ordering. It’s easier to correct the structure, or design for it, than to adjust a finished bespoke door.
Think about the head detail
With a true floor-to-ceiling door there’s no wall above the frame. The frame head is fixed at ceiling level, so the ceiling and the structure above need to give the frame something solid to fix to. In a stud wall that usually means adding timber or metal noggins at the head. Agree the detail with your builder at first fix.
Consider which way it opens
Concealed doors are flush on one face only, depending on whether they’re push or pull opening. On the other side you’ll see the frame reveal. Decide which room should get the seamless face. Our concealed door hinges guide explains the options.
Allow for clearances
A tall door still needs clearance at the floor, and some rooms need an undercut or other ventilation route. Check your ventilation plans and floor finish before the door is made, as the clearance affects the final leaf size.
Finishing a full-height door
Most full-height concealed doors arrive primed, ready to paint in the same colour as the wall. Using the same colour and sheen on the door and wall gives the strongest hidden-door effect. For a bolder look, a contrasting colour turns the door into a feature. Handles matter too: a slim pull, a flush handle or a push-to-open latch keeps the look minimal. See our concealed door handles guide for ideas.
Frequently asked questions
How tall can a floor-to-ceiling door be?
It depends on the manufacturer and system. Our Bespoke Concealed Door Set is made to measure up to 3m door height. For anything taller, ask for advice before you design around it.
Are floor-to-ceiling doors more expensive?
Usually, yes. Because the leaf is a non-standard size, it’s made to order, and the frame and hardware need to suit the extra height and weight. Lead times are also longer than for stock doors, so plan ahead.
Can I fit a floor-to-ceiling door in an existing wall?
Often, yes, but it’s more work than replacing a standard door. The opening has to be formed up to the ceiling, and in a masonry wall that may mean structural work. If the wall is load-bearing, get advice from a structural engineer, as this kind of alteration needs Building Regulations approval.
Can a floor-to-ceiling door be a fire door?
Fire-rated concealed doors are available, but fire doors can only be used within the sizes and configurations covered by their test evidence. Check the certified maximum size with the manufacturer before planning a full-height fire door.
Do full-height doors need special hinges?
They need hinges rated for the weight of the leaf, and often more of them than a standard door. Concealed full-height doors normally use adjustable concealed hinges supplied with the doorset.
