Layout & preparation

New Fixture Positions & Route Planning

The proposed fixture positions are reviewed alongside the existing room and service routes. Cabinetry, stonework, doors, and fixture dimensions are coordinated before the new plumbing layout is established.

Key consideration · Document the existing and proposed layouts and confirm the permit scope with the local authority.
Layout & preparation

Isolation & Old Fixture Disconnection

The water supply is isolated and the old fixture is carefully disconnected. Temporary caps and plugs close the exposed connections while retained finishes and removed fixtures are protected.

Key consideration · Temporary closures support the work sequence. Unused branches must be addressed in the approved final design.
New water & drainage routes

Hot & Cold Water Rerouting

Independent hot and cold supplies are brought to the new fixture position and secured within the service wall. The rough-in locations are coordinated with the future cabinet, faucet, and finished wall.

Key consideration · Bare copper shows an unfinished stage. Complete required insulation, protection, flushing, and testing before closure.
New water & drainage routes

Relocated Drain & Upward Vent Connection

The new lavatory drain inlet connects to an upright sanitary tee. Drainage continues downward, while the vent rises through the solid wall above the connection.

Key consideration · Coordinate the fixture trap arm and vent route with the approved layout; relocation changes more than the visible fixture position.
New water & drainage routes

Toilet Drain Branch Relocation

The toilet drainage branch is rerouted through an accessible floor bay toward the planned fixture location. A capped riser marks the rough connection while the surrounding framing remains intact.

Key consideration · This stage precedes flange installation. Coordinate the final flange with the finished floor, drainage route, and required venting.
Shower & tub rough-in

Shower Valve & Outlet Relocation

The shower control is moved to its planned position and anchored to solid blocking. Separate supplies feed the valve, and a supported riser reaches the future showerhead outlet.

Key consideration · Use the required protective shower valve and compatible trim; coordinate installation depth with the finished wall and waterproofing.
Shower & tub rough-in

New Tub Drain & Filler Connections

The freestanding tub position is coordinated with its drain and the floor-mounted filler. The filler base is anchored in the floor assembly, with separate supplies and a distinct drain connection prepared nearby.

Key consideration · Follow the selected tub and filler dimensions, mounting instructions, and service-access requirements before finish flooring is completed.
Review & final connections

Rough Plumbing Review Before Closure

The exposed routes, connections, supports, and planned fixture positions are reviewed while the work remains accessible. Required testing and rough inspections are coordinated before walls and floors are closed.

Key consideration · This image illustrates a review, not an inspection approval or a documented test result.
Review & final connections

Fixture Installation at the New Location

The fixture is installed at its new position and connected to the prepared water and drainage outlets. Accessible shutoffs, separate supply connectors, and a serviceable trap support future maintenance.

Key consideration · Follow the fixture instructions, maintain access to serviceable joints, and check the completed connections for leakage.
Review & final connections

Operation Checks & Completed Layout

The relocated fixtures are checked for normal operation, drainage, and leakage at accessible joints. Remaining adjustments and the required final inspection are coordinated before project handover.

Key consideration · Final acceptance comes from the local authority; the completed-room illustration does not establish an inspection pass.

Planned for California projects

These AI-generated images illustrate typical fixture relocation stages; they are not a photographic record of one renovation or completed Omega projects. Actual work follows the applicable California codes, approved plans, product instructions, and local amendments.

California code & project considerations
  • Confirm the applicable code edition, permit scope, and inspection sequence with the local authority. Current municipal bathroom guides reference the 2025 California Plumbing Code and call for existing and proposed layouts when fixtures move.
  • Review new drainage and vent routes together. Maintain proper trap-arm connections, drainage fittings, support, and required venting at the new fixture positions.
  • Protect the building structure and pipe penetrations. Provide the required protection against physical damage and fasteners; pipe routing must not seriously weaken structural members.
  • Complete required water-pipe insulation, flushing, and testing. Address unused supply branches in the approved design; CPC §309.6 requires a flushing method for dead legs.
  • Coordinate toilet flange placement with the finished floor. The capped toilet riser shown here is an earlier rough stage, before the flange and fixture are installed.
  • Coordinate shower control, waterproofing, and tub or filler anchorage with the selected products. Preserve access to connections that require service access.
  • Arrange required rough tests and inspections before concealment and final inspection after completion. Do not use compressed air to test plastic drainage piping.
