Which Door in This Range Fits Each Opening?
Match the door to the wall finish and room condition. A true invisible door is only worthwhile where the wall is meant to read as uninterrupted; elsewhere, a flush leaf with a visible frame achieves a similar clean look at lower site risk. Compare broader styles on the Interior Doors page.
| Model | Best For | Main Check |
|---|---|---|
| Invisible Flush Wall Door | Feature walls, villas, hotel suites | Wall flatness and frame depth |
| Flush Painted Interior Door | Apartments and bedrooms | Paint system and edge finish |
| WPC Waterproof Door | Bathrooms, damp service rooms | Frame material and wet-side detail |
| Door Frame & Architrave Set | Standard openings, renovations | Wall thickness range and joints |
What Must Be Decided Before the Wall Is Built?
The frame, the wall build-up and the finish must be agreed before any lining goes up. Once the wall is closed, a depth mistake usually means cutting back finished work.
- Record the structural opening and each layer of the wall section.
- Set the finished wall face as the reference, not the blockwork or stud.
- Show swing side, because the flush face normally sits on one side only.
- Confirm who installs the frame, and at what stage.
Issue a frame section for each wall type. Projects with mixed plasterboard, masonry and tiled walls will usually need more than one detail.
Why Does the Swing Direction Change the Design?
An invisible door is normally flush on the side where hinges are hidden, so the swing direction determines which room gets the seamless view. Decide which side matters most before ordering.
Opposite faces can look different. A door may be perfectly flush in a living room yet show a recessed reveal inside the storage room behind it. Designers should mark the show side on every elevation. If both sides must look flush, ask for a specific detail early, because a standard concealed frame may not achieve this without a thicker wall or a special frame.
How Flat Must the Wall Be?
The wall must be flatter than a typical painted wall would need, because the door edge exposes every deviation. Raking light from a nearby window or wall washer will reveal a small step at the frame line, even when the door itself is accurately made.
- Fix and plumb the frame before lining the wall.
- Check the frame again immediately before plastering.
- Protect the frame edge from trowels and sanding.
- Apply the final paint coat after the leaf has been adjusted.
Tolerances should be agreed with the wall contractor, since these details depend on site work as much as on factory accuracy.
How Do Concealed Hinges Limit the Door?
Concealed hinges carry the whole leaf from within the frame, so their load rating and opening angle set the design limits. Tall or panel-clad doors weigh more than a painted leaf, and stone or thick cladding can exceed the capacity of common hinges.
Send the leaf size and every layer of cladding so that the total weight can be calculated. Then check three points against the hinge maker's data: the number of hinges, the maximum opening angle, and the clearance of the leaf edge during swing. Some concealed hinges open less than a standard hinge, which can matter for furniture access and accessibility routes.
Paint, Panel or Veneer: Which Face Stays Invisible?
Painted walls give the most convincing result, but paneled walls are often easier to manage. A panel joint already creates a natural line, so the door gap can be disguised as one of the wall's repeated grooves.
- Painted: use the same paint system on wall and leaf, and expect different substrates to age slightly differently.
- Veneer: plan grain continuity across the leaf and adjacent panels.
- Fluted panels: set the door edges inside a groove so the pattern carries across.
- Wallcovering: resolve wrap and edge wear before specifying it, because the door edge sees constant contact.
Where Does a WPC Waterproof Door Make Sense?
Use WPC where moisture is regular and repainting is unwelcome, such as bathrooms in rental apartments, staff washrooms and damp service areas. It tolerates moisture better than an ordinary timber-based leaf, though the frame and hardware must be specified to the same standard.
A waterproof leaf in a standard MDF frame still leaves the frame exposed at floor level. Ask for a matching moisture-resistant frame, and use corrosion-resistant hinges and locks. Keep the frame base clear of standing water, and seal joints as the local installer's method requires. Also confirm the appearance, since WPC faces may not match painted doors nearby.
Can an Invisible Door Be Fire-Rated or Acoustic?
Do not assume so. Fire and acoustic performance belong to the complete tested assembly, including leaf, frame, seals and hardware, and a concealed frame may not be covered by the test evidence your authority requires. Raise this at the start so the correct assembly can be reviewed.
If the opening is on a fire route or a guestroom corridor, send the required rating and local standard first. Where no evidence is available for a concealed design, a framed rated door is the safer path. The same applies to acoustic targets, as gaps around the leaf often weaken sound control more than the door core does.
How Should Handles and Latches Be Chosen?
Select the operation method according to how often the door is used. Push-to-open suits occasional storage rooms, while busy bathrooms and service doors usually need a real handle and a privacy function.
A recessed pull keeps the surface clean, though it still marks the door's position. Without any handle, fingerprints gather at the push point, so paint choice and cleaning matter. Check emergency opening for bathroom locks, and check accessibility rules for public areas. Magnetic latches run quietly, which suits bedrooms and hotel suites, but confirm that the latch still holds the leaf closed against air pressure from ventilation systems. Test the selected hardware on your mock-up with the true leaf weight, then record the result as the production reference, following the checks described on our quality page.
