Showers

Summary
Quick reference guide for key criteria

Overarching requirements
Embellishments should be designed/selected and installed as follows:
- Fit for purpose, appropriately positioned and accessible.
- Durable, robust and safe (suitable for corrosive environments).
- Vandal resistant with parts that are easily replaceable.
- Easy to maintain (with appropriate warranty and workmanship).
- Comply with relevant standards, legislation, corporate documents and approvals
Planning, design and positioning
- Link shower to a pedestrian pathway
- Must be installed by a licensed plumber
- A plumbing permit may be required
- All fittings and pipes must have Watermark approval
- Approvals required.
Shower requirements
- (A) Activation controls (tapware)
- Ceramic disc (quarter turn lever) - installed at high use locations
- (B) Timed flow (push button) - installed at low use locations
- (C) Access panels must be provided at back of shower unit for repair/maintenance
- Provisions to be made for the installation of smart technologies (100 x 100 x 100 mm). Recommended post size of 135 x 135 mm
- Provide a maintenance tap at back of shower unit or very close proximity to shower
- Double showers should include towel rail and foot shower
- (D) Shower floor/base - refer to quick criteria guide – shower waste water discharge.
(E) Materials, fixings and connections
- Shower design to be bolt down to base material
- Connect shower to mains water supply with the appropriate dual check valve, isolation valve and pressure limiting valve Installed in an easily accessible location within 1.0 m of the shower unit.
- An isolation valve (for emergency shut off) on the supply line of each embellishment.

Waste water discharge methods
- 1. Natural dunal discharge (most preferred wastewater disposal method)
- 2. Soakage trench where dunal discharge is not feasible. A soakage trench must be positioned away from foot traffic (as it can compact the area), and away from tree roots and underground services. Must be machine accessible for maintenance.
- 3. Open space discharge or 4. Piped to dunal areas.
- Discharging wastewater into stormwater is NOT accepted
- Approvals required.
Waste water discharge infrastructure
- Shower floor/base
- Must have a fall, (min 2 degrees) to prevent water ponding
- Material must have slip resistant surface and discourage build-up of algae (fibre reinforced plastic preferred). Must be flush with finished surface
- Grates with hinges not preferred
- Ideally select standardised components such as 38mm thick fibre reinforced plastic (FRP) mesh.
- Pits
- Concrete pit or
- PVC pit where the pit will not be driven over by maintenance vehicles.
- Polycrete is not preferred.
- Length determined by shower floor area.
- Outlet pipes
- As straight as possible with minimal bends
- Raised min 200 mm from base of pit
- Pipe min 150 mm dia.
Finishes, fixings and connections
- Connect shower to mains water supply with the appropriate dual check valve, isolation valve, pressure limiting valve and downstream of water meter. Installed in an easily accessible location within 1.0 m of the shower unit.
- An isolation valve (for emergency shut off) on the supply line of each embellishment.
