LED-backlit wardrobe mirror in a Sadashivanagar walk-in: when the RCP electrical placement breaks the soft-close hinge specification mid-install

The mirror sits 1200mm wide, backlit with warm LED strip at 3000K, mounted to the rear wall of a walk-in wardrobe in a Sadashivanagar townhouse. The electrical rough-in for the transformer and dimmer was marked on the RCP at 150mm from the left edge of the mirror frame. The soft-close hinge spec for the wardrobe door—a 10mm frameless glass panel with integrated handle—required 120mm clear depth from the inner edge of the frame to the first obstruction. The electrical conduit, when run, sat at 100mm. On handover, the door would not close without binding.

This is not a rare problem. It happens in Bangalore's post-2015 residential boom, where RCPs are drawn by architects, electrical rough-ins are coordinated by MEP consultants, and wardrobe specs are handed to the glass atelier with no cross-reference to either. The result is a site visit, a redesign, and a delay that could have been prevented with a single coordination sketch.

The RCP as a silent contract

The reflected ceiling plan is where electrical, HVAC, and structural elements live on paper. For a wardrobe mirror with integrated LED and dimmer control, the RCP shows the transformer location, the conduit run, and the height of the backlit strip. It does not, by convention, show the depth of the wardrobe frame, the swing arc of the door, or the hinge-to-obstruction clearance. These details live in the wardrobe spec sheet and the shop drawing. The gap between these two documents is where site problems are born.

In the Sadashivanagar case, the architect had specified the mirror location on the RCP. The electrical consultant had marked the transformer rough-in based on available wall space and standard conduit runs. Neither had cross-checked the wardrobe door's soft-close mechanism, which requires unobstructed swing space. By the time the glass atelier arrived with the shop drawing—showing the frame depth, the hinge position, and the required clearance—the electrical rough-in was already in the wall.

Why soft-close hinges demand precision in the spec phase

The hinge geometry and its non-negotiable clearance

A soft-close hinge on a frameless glass wardrobe door is a precision component. The hinge barrel sits 12mm proud of the frame edge. The damping mechanism inside requires a full 120mm of unobstructed depth from the inner face of the frame to the first wall obstruction—whether that is a stud, a conduit, or a transformer box. If an electrical rough-in encroaches into this zone, the door will bind, the hinge will take load it was not designed for, and the soft-close function will fail within months.

The hinge spec is not negotiable because it is not a preference—it is a warranty condition. If the door binds due to obstruction, the hinge manufacturer will not honor the warranty, and the atelier cannot be held responsible for a condition created by the MEP scope.

The RCP must show the wardrobe frame footprint

To prevent this, the RCP should include a dashed outline of the wardrobe frame—not just the mirror surface, but the full depth of the frame assembly. In the Sadashivanagar project, the frame was 40mm deep (10mm glass plus 30mm aluminum sub-frame). The hinge sat 12mm proud of that. The required clear depth was therefore 52mm from the wall surface to the hinge barrel, and 120mm beyond that to the first obstruction. The electrical rough-in at 100mm from the wall was directly in conflict.

A simple coordination sketch—showing the frame outline, the hinge position, and the 120mm clear zone—would have flagged this before the electrical conduit was run. Instead, the discovery happened on site, during the glass installation phase, when changes are costly and time is short.

Coordination protocol: what to spec and when

The wardrobe spec sheet must include RCP-relevant dimensions

When you commission a wardrobe mirror with LED and soft-close hardware, the spec sheet should include:

• Frame depth (typically 30–40mm for aluminum sub-frames)
• Hinge type and barrel projection (12mm for standard soft-close hinges)
• Required clear depth from wall to first obstruction (120mm minimum for soft-close function)
• Electrical rough-in location and depth (if known from the RCP)
• Any conduit or transformer boxes that will be in the wall plane

This information must be shared with the electrical consultant before the RCP is finalized. The MEP scope should then confirm that no rough-in will encroach into the clear zone. This is not the atelier's responsibility—it is a coordination task between the architect, the electrical consultant, and the interior designer on site.

The shop drawing becomes the verification point

Once the wardrobe is designed and dimensioned, the shop drawing should include a section detail showing the frame-to-wall relationship, the hinge position, and the clear zone. This drawing should be cross-checked against the RCP and the electrical rough-in plan before fabrication begins. Any conflict should be resolved at this stage—either by relocating the electrical rough-in, by adjusting the frame position, or by specifying a different hinge type (if one exists that requires less clearance, though this is rare).

In practice, this cross-check often does not happen. The atelier receives a spec sheet and a room dimension, draws the shop drawing in isolation, and only discovers the conflict when the frame arrives on site and the electrical rough-in is already in the wall.

The Sadashivanagar resolution: cost and time

The site solution required three options:

• Relocate the electrical rough-in 150mm to the right, away from the hinge zone. This required re-running conduit and was approved by the MEP consultant, but added one week to the electrical schedule and cost the client an additional 8,000 rupees in labor and materials.
• Reposition the mirror frame 80mm to the left, moving it closer to the corner. This reduced the usable mirror width by 60mm and was rejected by the interior designer as a visual compromise.
• Specify a non-soft-close hinge and accept manual door closure. This eliminated the warranty issue but was rejected by the client, who had specified soft-close as a finish standard.

The project chose option one. The electrical rough-in was relocated. The wardrobe was installed on schedule, and the soft-close hinge functioned as specified. But the delay and cost could have been eliminated with a single coordination sketch in the design phase.

Specification best practice for LED-backlit mirrors in Bangalore walk-ins

For architects and interior designers specifying LED-backlit wardrobe mirrors in Bangalore residential projects, a checklist:

• Include the wardrobe frame footprint on the RCP, with a dashed outline showing the full depth of the assembly.
• Specify the hinge type and its clearance requirement in the wardrobe spec sheet, and share this with the MEP consultant before the RCP is finalized.
• Request a coordination sketch from the atelier showing the frame position, the hinge location, and the 120mm clear zone. Cross-check this against the electrical rough-in plan.
• If the electrical rough-in conflicts with the clear zone, resolve it in the design phase by relocating the rough-in or adjusting the frame position. Do not defer this to the site phase.
• For frameless glass wardrobes with integrated LED and soft-close hardware, budget for a coordination meeting between the architect, the MEP consultant, the interior designer, and the glass atelier before the RCP is signed off.

Bangalore's monsoon humidity (June–September) and the hard water from the Cauvery (TDS 200–300 ppm) both affect the longevity of electrical components and hinge mechanisms in wet areas like bathrooms, but walk-in wardrobes are typically dry. The real risk in a walk-in is not moisture—it is obstruction. A soft-close hinge that binds will fail faster than one that swings freely, regardless of humidity or water quality.

When to specify a different hinge or frame depth

If your project has severe spatial constraints—a narrow walk-in, a wall with multiple rough-ins, or a load-bearing wall where conduit placement is fixed—consider:

A shallower frame. Some atelier-commissioned wardrobes can be built with a 20mm sub-frame instead of 30mm, reducing the overall wall projection. This does not change the hinge clearance requirement, but it reduces the total footprint of the assembly. However, a shallower frame may reduce rigidity, particularly for large mirrors (over 1400mm wide), and should be verified with the atelier before specifying.

A pivot hinge instead of a butt hinge. Pivot hinges mount at the top and bottom of the door, not along the side, and therefore require a different clear-zone geometry. They are less common in Bangalore residential projects and are typically more expensive, but they may solve a spatial conflict if a soft-close butt hinge cannot be accommodated. Again, this should be confirmed with the atelier and the hardware supplier before the spec is finalized.

In the Sadashivanagar project, neither option was necessary—the electrical rough-in was simply relocated—but these alternatives are worth considering in projects where wall space is genuinely constrained.

The atelier's role in coordination

When you commission a wardrobe from an atelier, the atelier's responsibility is to deliver a shop drawing that is accurate to the site dimensions and the specified hardware. The atelier cannot coordinate the RCP or the electrical rough-in—that is the architect's and MEP consultant's job. However, the atelier can flag potential conflicts if the spec sheet includes electrical or structural information, and the atelier's shop drawing should be treated as a verification point, not a formality.

Request the shop drawing early—ideally before the electrical rough-in is run—and cross-check it against the RCP. If a conflict is identified, resolve it before fabrication begins. The cost of a design change at the drawing stage is always lower than the cost of a change on site.

Questions we get asked

Can a soft-close hinge work in a space with less than 120mm clear depth?

No. A soft-close hinge requires 120mm of unobstructed swing space from the inner face of the frame to the first wall obstruction. If this space is encroached, the hinge will bind, the damping mechanism will not function, and the door will not close smoothly. The 120mm figure is a manufacturer specification and is not negotiable. If your wall space cannot accommodate this, you must either relocate the obstruction, adjust the frame position, or specify a non-soft-close hinge.

Who is responsible for coordinating the RCP and the wardrobe spec?

The architect is responsible for the overall coordination. The architect should share the wardrobe spec (including frame depth, hinge type, and clear-zone requirement) with the MEP consultant before the RCP is finalized. The interior designer or the atelier can flag conflicts when the shop drawing is prepared, but the resolution is the architect's responsibility. Do not assume that the electrical consultant knows about wardrobe hardware clearances—they do not, unless you tell them.

What if the electrical rough-in is already in the wall when we discover the conflict?

The options are to relocate the rough-in (cost and time), reposition the frame (may affect the design), or change the hinge type (may not be possible). None of these are ideal. This is why coordination in the design phase is critical. If you are already on site and discover a conflict, contact the atelier and the MEP consultant immediately. Do not proceed with installation until the conflict is resolved.

Does the LED backlight add any additional clearance requirement?

No. The LED strip is mounted to the rear face of the frame and does not affect the hinge clearance or the door swing. However, if the LED transformer or dimmer is mounted inside the frame (rather than in the wall), this will add depth to the frame assembly. Confirm with the atelier whether the transformer is wall-mounted or frame-mounted, and adjust the frame depth and clearance calculations accordingly.

Can we use a frameless mirror without a frame sub-structure to save space?

A frameless mirror with soft-close hinges still requires a sub-frame—typically 30mm aluminum—to house the hinge mechanism and to provide rigidity. The "frameless" refers to the visible edge of the glass (which is unframed), not to the absence of a structural sub-frame. The 120mm clear-zone requirement applies regardless of whether the frame is visible or hidden. There is no way to eliminate this requirement without changing the hinge type.

Commissioning a wardrobe mirror with coordination in mind

If you are specifying an LED-backlit wardrobe mirror with integrated soft-close hardware, begin with a coordination sketch. Share the wardrobe spec—frame depth, hinge type, clear-zone requirement, and electrical rough-in location—with all parties (architect, MEP consultant, interior designer, atelier) before the RCP is finalized. Request a shop drawing from the atelier that includes a section detail showing the frame-to-wall relationship and the hinge clearance. Cross-check this against the RCP. Resolve any conflicts in the design phase. This adds one week to the design schedule but eliminates the risk of a site conflict and the cost of a late-stage redesign.

For wardrobes with pattern or texture—such as our Bronze Lattice or Deco Noir finishes—the coordination protocol is identical. The pattern does not affect the hinge clearance, but it does affect the visual impact of any frame adjustments. If you must reposition the frame to accommodate an electrical rough-in, a patterned wardrobe may show the shift more visibly than a clear mirror. This is another reason to resolve conflicts early.

Talk to the atelier about your project. Bring the RCP, the wardrobe spec, and the electrical rough-in plan. We will prepare a coordination sketch and flag any conflicts before fabrication begins. A single conversation at the design stage is worth more than a dozen site visits.
