Multi-unit residential projects are driven by standardisation, acoustic performance and maintenance access. Specifying one drain across all units simplifies procurement, installation and long-term servicing.
What matters in apartment projects
| Requirement | Why it matters |
|---|---|
| Standardisation | One specification across all units — simpler ordering, installation and spares |
| Acoustic performance | Impact and flow noise transmit to the unit below |
| Maintenance access | Service must not require access to the unit below |
| Waterproofing reliability | Defects in one unit become a claim against the developer |
| Installation speed | Repeat installation across many identical units |
| Spares availability | Grates and traps get damaged; parts must be available for years |
Acoustics
Noise from a shower drain reaches the unit below through two routes: impact noise transmitted through the structure, and flow noise through the pipe itself. Both are addressed at detail stage rather than after handover.
- Decoupling layer between the drain and the structure
- Rigid, independent support for the drain body
- Correct venting to prevent gurgling
- Insulation on pipe runs where practical
- Acoustic requirements in multi-unit buildings are usually set by local building regulations — confirm the applicable standard
Maintenance access
The hair trap must be serviceable from inside the bathroom. Any design that requires opening the ceiling below converts a one-minute cleaning task into a maintenance visit requiring tenant access — a cost that repeats for the life of the building.
Procurement approach
- Confirm one specification across all units
- Order against the full quantity with a spares allowance
- Arrange staged delivery to match the construction programme
- Confirm spares availability for the maintenance period
