An electrician’s role in a bathroom renovation is to safely disconnect existing electrical systems, install new wiring during the rough-in stage, and complete the final fit-off of lights, switches, fans, and power points—ensuring everything is compliant, functional, and safe in a wet environment.
Key Takeaways
- Electricians are typically the first and last trade on-site during a bathroom renovation
- Electrical work in bathrooms must meet strict safety regulations due to water exposure
- Most basic bathroom electrical work costs around $2,000–$3,000 in Melbourne
- Lighting is the biggest factor that increases electrical costs
- Proper planning early in the renovation prevents costly changes later
What Does an Electrician Do in a Bathroom Renovation?
An electrician is responsible for all electrical components within the bathroom, from making the space safe before demolition through to installing and testing all final fixtures.

Their role typically includes:
- Disconnecting and isolating existing electrical systems
- Running new cables and repositioning wiring
- Installing lighting, switches, power points, and exhaust fans
- Ensuring all work complies with Australian standards
If you’re planning a renovation, it helps to understand how electricians fit into the broader process. You can see how they integrate with other trades in this guide on trades involved in bathroom renovations.
When Does the Electrician Come In During a Bathroom Renovation?
Electricians are involved at multiple stages of a bathroom renovation, typically coming in before demolition, during the rough-in phase, and again at the final fit-off stage. They are often one of the first trades on-site and one of the last to leave, ensuring everything is safe, functional, and fully installed.
Before demolition: making the site safe
Before any demolition begins, the electrician disconnects power and removes fittings like lights, switches, and power points.
To keep the site safe, exposed wiring is secured using junction boxes and connectors so it can’t be accidentally touched or cause harm.
This step is critical—it allows demolition to proceed safely without risk of electrical hazards.

After demolition: rough-in stage
Once the bathroom has been stripped back, the electrician returns to run cables and prepare the electrical layout.
This includes:
- Repositioning wiring based on the new design
- Removing redundant cables
- Running new circuits for lighting, fans, and outlets
At this stage, electricians often work alongside plumbers, coordinating layouts inside walls before everything is closed up.
Final stage: fit-off and installation
After tiling and major works are complete, the electrician comes back for the final fit-off.
This involves:
- Installing lights, switches, and power points
- Connecting exhaust fans and heated elements
- Testing all electrical components
This is when the bathroom comes to life from an electrical perspective.

How Electricians Work Alongside Plumbers in Bathroom Renovations
Electricians and plumbers often overlap during the rough-in stage, making coordination between the two essential.
Both trades need access to wall cavities and must plan around:
- Pipe locations
- Fixture placements
- Structural elements
Poor coordination can lead to rework, delays, or compromised layouts.
If you’re looking to understand this relationship in more detail, the upcoming guide on the plumber’s role in bathroom renovations will break this down further.

Bathroom Electrical Safety Requirements (What You Need to Know)
Bathroom electrical work is governed by strict safety standards due to the presence of water.
Safe distances from water sources
Electrical fittings must be installed at safe distances from sinks, showers, and baths. Clearances vary depending on the size and layout but are essential for safety compliance.
Low voltage requirements in wet areas
Lighting near wet zones, particularly above baths or inside shower areas, must often be extra low voltage to reduce risk.
Licensed electrical work only
All bathroom electrical work must be completed by a licensed electrician. This ensures compliance with regulations and protects both safety and insurance coverage.

How Much Does Electrical Work Cost in a Bathroom Renovation?
Electrical costs can vary depending on the complexity of the design, but most standard bathroom renovations fall within a predictable range.
Typical cost range for Melbourne bathrooms
For a basic bathroom setup, electrical work usually costs between $2,000 and $3,000.
This typically covers:
- A couple of downlights
- An exhaust fan
- Two to three power points
- A light switch
What increases the cost?
Lighting is the biggest cost driver in most bathroom renovations.
Upgrades that increase costs include:
- Feature wall lighting
- LED strip lighting
- Under-vanity or recessed lighting
- Complex lighting layouts
Basic vs high-end electrical fit-outs
A simple bathroom keeps things functional and cost-effective, while high-end designs often prioritise aesthetics through layered lighting and custom features.

Common Electrical Features in Modern Bathroom Renovations
Most modern bathrooms include a mix of functional and aesthetic electrical features.
Common inclusions:
- Downlights for general lighting
- Exhaust fans for ventilation
- Power points (typically near the vanity)
- LED strip lighting for ambience
- Underfloor heating (electrician connects the system)

Common Mistakes to Avoid with Bathroom Electrical Work
Mistakes in electrical planning can be expensive and difficult to fix once the renovation is underway.
Common issues include:
- Not planning lighting early
- Poor placement of switches and power points
- Trying to change layouts after tiling
- Ignoring compliance requirements
Getting the electrical plan right from the start avoids unnecessary delays and added costs.
