Assessment & controlled removal

Bathroom Layout & Fixture Assessment

The existing bathroom is reviewed against the new fixture layout and finish selections. Sink, shower, tub, and toilet positions are coordinated with the available service routes before removal begins.

Key consideration · Confirm fixture dimensions, installation instructions, and the work covered by the remodel permit.
Assessment & controlled removal

Fixture Disconnection & Removal

Water supplies are isolated and the old fixtures are disconnected with nearby finishes protected. Removed items are supported safely, and unused water and drain openings are closed while the work area is prepared.

Key consideration · Confirm isolation before disconnection and protect retained floors, cabinets, and stone surfaces.

Hot & Cold Supply Relocation

Separate hot and cold lines are positioned for the revised vanity layout and secured to blocking. Accessible rough-in connections are coordinated with the future cabinet and finished wall surfaces.

Key consideration · This unfinished view shows bare copper. Complete required insulation, pipe protection, and testing before concealment.

Drain & Vent Rough-In

The fixture drain inlet connects to a vertical drain-and-vent arrangement. The drain continues downward while the vent rises through the wall, keeping the vent route visible during the rough stage.

Key consideration · Coordinate the trap-arm connection and vent route with the approved bathroom layout before the wall is closed.

Shower Valve & Riser Installation

The shower valve is anchored to blocking and connected to separate hot and cold supplies. A supported riser leads to the future showerhead outlet, with unused valve outlets closed as required by the selected product.

Key consideration · Use the required protective shower control and set the mounting depth for the intended finished wall and compatible trim.
Waterproofing & fixture installation

Shower Receptor Waterproofing & Water Check

Before tile and finish completion, the shower receptor waterproofing is checked with the appropriate test closure and contained water. Seams, corners, the curb, and the drain connection are coordinated as one waterproofing system.

Key consideration · Follow the selected waterproofing system and required local test and inspection conditions; this image does not record a passed test.

Vanity, Faucet & Drain Connections

The new basin and faucet connect to the prepared water and drain outlets. Separate supply connectors and a serviceable P-trap are arranged within the cabinet, with access to the shutoffs and drain joints.

Key consideration · Follow the fixture mounting instructions and keep serviceable connections accessible after the cabinetry is complete.

Freestanding Tub & Filler Installation

The tub is positioned for its prepared drain connection and the filler is secured to its mounting assembly. The fixed spout remains above the tub rim while the concealed connections follow the selected fixture design.

Key consideration · Coordinate anchorage, drainage, service access, and the required temperature and backflow protection for the tub and filler.

Toilet Flange, Seal & Fixture Setting

The toilet bowl is aligned with the secured flange and approved seal before being lowered into place. The flange position is coordinated with the finished floor, followed by fastening and the final water connection.

Key consideration · Use the specified seal and mounting hardware, and secure and seal the fixture as required without overtightening the china.
Operation checks & completion

Final Fixture Checks & Inspection Readiness

The installed fixtures are checked for normal operation, drainage, and leakage at accessible joints. Temperature-control checks, remaining adjustments, and required inspection steps are coordinated before project handover.

Key consideration · Final acceptance is issued by the local authority. This illustration shows an operation check, not an inspection approval.

Planned for California projects

These AI-generated images illustrate typical bathroom remodeling 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 remodel permit and inspection sequence with the local authority. Current municipal bathroom guides reference the 2025 California Plumbing Code.
  • Coordinate rough testing and review before concealment, any required receptor or waterproofing inspection, and the final inspection after the affected work is complete.
  • Maintain proper fixture drainage and vent connections. Bare hot-water piping in rough-stage images remains subject to required insulation before closure.
  • Use the protective shower control required by CPC §408.4 and compatible trim. Valve appearance alone does not verify its listing or temperature performance.
  • Install the shower waterproofing as a coordinated system and perform the required receptor test before the relevant finish work. The illustration does not establish test depth, duration, or acceptance.
  • Secure toilet flanges at the finished floor, use approved seals, and follow the fixture mounting instructions.
  • Preserve service access and provide the temperature and backflow protection applicable to the selected tub and filler.
