Step-by-Step
1. Layout planning – finalise the design and positions for the bath, shower, sink, and other fixtures.
2. Prepare plumbing – check existing piping, remove old fixtures if renovating, and plan new connections.
3. Mount fixtures – securely fix taps, shower enclosures, and cabinetry according to the design.
4. Connect plumbing – link waste pipes and inlets ensuring all joints are sealed.
5. Seal and waterproof – apply silicone sealant or waterproofing membranes around joints and edges.
6. Install finishes – lay tiles or wall coverings and complete final fixture fittings.
7. Final testing – check water pressure, drainage and verify that all connections are leak-free.
Completion Checks
• All fixtures are level, securely fixed and operate correctly.
• No leaks are detected around taps, joints or under the basin.
• Water pressure and drainage have been fully tested.
• Finishing details provide a complete, waterproof and stylish installation.
When to Call a Pro Instead
If your bathroom installation involves complex plumbing alterations, structural modifications or integration with additional systems like underfloor heating, a registered plumber or NICEIC‐registered electrician should be consulted to ensure compliance, safety and warranty protection.
