Wall Opening & Surface Clearance Scope
The detail should show the coordinated opening through the finished-wall
assembly and the clearances required around the concealed faucet connection.
Reference the final finished-surface plane, wall penetration, trim coverage,
supporting substrate and surrounding construction. Only verified manufacturer
dimensions should be used in final construction documents.
Complete Wall Opening Detail
Show the finished wall, coordinated penetration, concealed connection,
trim coverage and surrounding construction in one enlarged detail.
Finished-Surface Plane
Use the final tile, stone or other architectural finish as the
reference plane for exposed trim and concealed connection depth.
Wall Opening
Show the required penetration through the wall assembly while
avoiding an unnecessarily oversized opening around the faucet connection.
Opening Centerline
Align the wall penetration with the concealed connection and
exposed faucet centerline.
Finish Thickness
Coordinate the complete build-up of substrate, waterproofing,
adhesive and final finish material when setting the installation depth.
Substrate Clearance
Maintain sufficient clearance around the concealed connection so
backer materials do not interfere with assembly or service.
Trim Coverage
Show the Brushed Gold trim extending sufficiently beyond the wall
opening to provide a clean finished interface.
Trim Seating Surface
Provide a flat and continuous finished surface so the trim seats
evenly without rocking or visible gaps.
Connection Clearance
Maintain adequate space around the concealed plumbing connection
for installation, tightening and inspection.
Thread Access
Keep the connection zone clear enough to permit proper thread
engagement without interference from finish materials.
Wall Sleeve Clearance
Where a sleeve is used, coordinate its diameter and position so
it does not prevent final trim installation.
Structural Blocking Clearance
Locate supporting blocking so it provides secure mounting without
restricting the required wall penetration.
Waterproofing Clearance
Integrate the penetration with the wall waterproofing system while
maintaining the required opening for the faucet connection.
Sealant Joint
Provide a compatible perimeter seal where required between exposed
trim and the finished architectural surface.
Tile Edge Clearance
Avoid placing cut tile or stone edges where they may interfere
with the trim seating area or concealed connection.
Stone Finish Clearance
Coordinate thicker stone finishes so the concealed connection
remains within its approved installation range.
Backer Board Opening
Keep the substrate opening aligned with the finished-wall
penetration and faucet centerline.
Membrane Penetration
Coordinate penetrations through waterproofing membranes to
maintain continuity around the fixture connection.
Wall Cavity Clearance
Maintain adequate internal clearance between the concealed
connection and adjacent framing or building services.
Service Clearance
Provide sufficient access around serviceable concealed components
for inspection and future maintenance.
Spout Opening Alignment
Position the wall opening so the exposed spout remains level
and perpendicular to the finished surface.
Sensor Opening Alignment
Coordinate any required sensor penetration with the faucet
assembly and intended detection field.
Edge Protection
Protect wiring, plumbing and fixture components from sharp
edges at metal framing or finish penetrations.
Finished Opening
Show the completed opening fully concealed by the installed
trim with no unnecessary exposed gaps.
Engineering note:
Wall-opening dimensions must not be based on estimated product measurements.
Confirm the required opening, finished-wall thickness, trim coverage,
connection depth and mounting clearances from the approved FontanaShowers
specification sheet or project submittal before wall fabrication.
Required Wall Opening Views
Front Opening Elevation
Show the opening centerline, penetration limits and trim
coverage relative to the finished wall.
Side Wall Section
Show framing, substrate, waterproofing, finish thickness
and concealed connection depth.
Trim Coverage Detail
Show the relationship between the finished opening and
exposed Brushed Gold trim.
Connection Clearance Detail
Show the clear space required around the plumbing connection
for installation and inspection.
Waterproofing Detail
Show how the fixture penetration interfaces with the
project waterproofing system.
Substrate Opening Detail
Show the backer-board opening and its alignment with
the final finish opening.
Structural Clearance View
Show the relationship between framing, blocking and the
required fixture penetration.
Finished Installation
Show the completed trim fully covering the coordinated
wall opening.
Recommended Wall Opening Sequence
1. Review Approved Submittals
Confirm the final faucet configuration, wall penetration
requirements and installation depth.
2. Confirm Wall Build-Up
Establish the combined thickness of substrate, waterproofing,
adhesive and finish material.
3. Establish Centerlines
Transfer the approved faucet and connection centerlines
to the wall assembly.
4. Coordinate Blocking
Install structural backing without obstructing the required
fixture opening or connection zone.
5. Prepare Substrate Opening
Create the required opening in the backer material while
maintaining alignment with the concealed connection.
6. Coordinate Waterproofing
Integrate the penetration with the selected waterproofing
system before final finish installation.
7. Install Finish Material
Cut tile, stone or other finish accurately around the
coordinated fixture opening.
8. Verify Opening Clearance
Check that the completed penetration does not interfere
with connection threads or installation hardware.
9. Test Trim Coverage
Dry-fit the trim and confirm it fully covers the finished
opening while seating flat against the surface.
10. Install Faucet Components
Complete the exposed faucet installation without damaging
the finished wall edges.
11. Seal Wall Interface
Apply compatible perimeter sealing where required around
the trim and finish interface.
12. Final Inspection
Verify trim seating, opening coverage, alignment and
absence of exposed gaps before project completion.
Architectural and MEP Coordination
Finish Coordination
Coordinate wall openings with final tile, stone or other
architectural finish dimensions.
Structural Coordination
Keep framing and backing clear of the required penetration
while maintaining suitable fixture support.
Plumbing Coordination
Ensure plumbing fittings and threaded connections remain
accessible through the coordinated wall opening.
Waterproofing Coordination
Integrate the fixture penetration into the wall moisture-control
system without obstructing final trim installation.
Electrical Coordination
Protect sensor and control wiring where it passes through
or adjacent to wall openings.
Millwork Coordination
Where adjacent casework is present, ensure it does not
restrict access to concealed fixture connections.
Trim Coordination
Maintain sufficient uninterrupted finished surface around
the opening for proper trim seating and coverage.
Maintenance Coordination
Provide reasonable future access to concealed connections
without unnecessary damage to permanent finishes.

Project verification:
This wall opening and finished-surface clearance resource is intended for
coordination and does not replace an approved project submittal. The architect,
plumbing engineer, wall-system designer, tile or stone installer and licensed
installer should verify final wall thickness, required opening size, connection
depth, trim coverage, waterproofing, structural support and locally adopted codes
before fabrication or installation.
