Installing an electric shower is a complex task requiring professional installation. However, many skilled DIYers prefer installing an electric shower because they already have experience dealing with electric circuits, wires, and plumbing.
You can go for a DIY electric shower installation if you have complete control over circuits, wires, plumbing units, waterproofing electrical connections, caulking, sealing, and replacing tiles. Only proceed with DIY electric shower installation if you are experienced in handling these tasks. If you have already started the project and cannot complete it, it is better to get professional help than cause a mishap.

Detailed Instructions
Choosing the Right Location
The first step in installing an electric shower is to choose the appropriate location in your bathroom. This spot should have access to both the water supply and electrical power. Before proceeding, it’s crucial to use a pipe and cable detector to check for any hidden pipes or cables in the wall where you plan to install the shower. This precaution helps avoid accidental damage during the installation process.
Preparing the Area
Once the location is chosen, prepare the area for installation. This involves turning off the main water supply and electricity to ensure safety. Then, mark the position for the shower unit on the wall, using a spirit level to ensure that it’s perfectly level. Accurate positioning is key for a proper installation.
Connecting Water Supply
The next step involves plumbing work. You need to cut into the cold water supply pipe using a pipe cutter and install a T-junction to connect the shower unit to the water supply. It’s important to ensure that all connections are secure and there are no leaks. This might require tightening the connections with adjustable wrenches.
Electrical Installation
For the electrical part, you need to install a dedicated circuit from your home’s electrical supply to the location of the shower. You can hire a professional electrician if you aren’t comfortable doing this. You can save a lot of money by doing the rest of the work yourself.
This includes using high-quality electrical cable that is suitable for wet areas. A circuit breaker should be fitted in your consumer unit for added safety, and an isolation switch should be installed outside the bathroom. This switch is crucial as it allows for immediate power disconnection in emergencies.
Mounting the Shower Unit
Now, you’re ready to mount the shower unit. This involves drilling holes in the wall for mounting brackets. If you’re drilling through tiles, use a tiling drill bit to prevent damage. Once the holes are drilled, secure the unit to the wall with screws, making sure all connections to the water supply and electric cable are tight and secure.
Finalizing the Installation
After mounting, apply waterproof sealant around the unit to prevent water ingress. Then, turn on the water supply and electricity to test the shower. Check thoroughly for any leaks and ensure that the shower is functioning correctly.
Safety Checks
Finally, conduct safety checks. This includes double-checking all electrical connections and ensuring the isolation switch and circuit breaker are working properly.
Safety Tips for Installing Electric Showers
- Turn Off Main Power and Water Supply: Ensure safety by turning off the main power and water supply before installing. This prevents accidental electrocution and water-related mishaps.
- Use a Pipe and Cable Detector: Employ a pipe and cable detector to avoid drilling into hidden pipes or electrical wires, which could lead to dangerous leaks or electrical hazards.
- Wear Appropriate Safety Gear: Always wear safety gear such as gloves, goggles, and non-slip shoes to protect against electrical shocks, water splashes, and debris from drilling.
- Check for Compliance with Local Regulations: Verify that your installation complies with local building and electrical codes to meet safety standards and legal requirements.
- Use the Correct Tools and Materials: Utilize tools and materials that are appropriate for electrical work in wet areas, like waterproof sealants and electrical cables designed for high moisture environments.
- Ensure Proper Ventilation: Work in a well-ventilated area to avoid inhaling harmful fumes from sealants or dust from drilling, which can be hazardous to your health.
- Avoid Working Alone: It’s safer to work with someone else who can assist in case of emergencies or at least ensure that someone is aware that you are undertaking this task.
- Regularly Inspect Your Tools and Equipment: Before starting, inspect your tools and equipment for any damage or wear that might pose a safety risk during installation.
- Follow Manufacturer’s Instructions: Adhere closely to the manufacturer’s installation guide, as it is tailored for the safe and correct installation of your specific electric shower model.
- Seek Professional Assistance if Unsure: If you’re uncertain about any aspect of the installation, it’s wise to consult with or hire a professional to avoid risks associated with improper installation.
Benefits of Electric Showers
- Instant Hot Water: Electric showers heat water on demand, providing hot water instantly without waiting for a water heater.
- Energy Efficiency: They only heat the water you use, potentially reducing energy consumption compared to traditional water heaters.
- No Dependency on Boiler: Electric showers do not rely on a home’s central heating system, making them useful in homes without a boiler or during boiler breakdowns.
- Consistent Temperature: Many models maintain a consistent water temperature, even if the water pressure fluctuates.
- Easy Installation: They can often be easier to install than other showers, as they typically require only a cold water supply and an electrical connection.
- Space Saving: Electric showers are compact, making them suitable for smaller bathrooms with limited space.
Frequently Asked Questions
What type of circuit breaker do I need for an electric shower?
The type of circuit breaker required for an electric shower depends on the power rating of the shower unit, which is typically measured in kilowatts (kW). Generally, a high-rated circuit breaker is necessary to handle the high electrical demand of an electric shower. For example, a shower with a power rating of 8.5 kW to 10.5 kW usually requires a 40-45 amp circuit breaker. It’s crucial to consult the manufacturer’s instructions for the specific requirements of your shower model and to ensure the circuit breaker is compatible with your home’s electrical system.
Can a beginner DIYer install an electric shower?
Installing an electric shower can be challenging for a beginner DIYer. It requires knowledge of both plumbing and electrical systems. Safety is a major concern, especially when dealing with electricity in a wet environment. It’s often recommended to hire a professional, particularly if you’re not confident in your electrical and plumbing skills.
How to adjust the temperature on an electric shower?
To adjust the temperature on an electric shower, typically, you use the temperature control dial or buttons on the unit. It allows you to select your desired temperature. Some models may have a digital display for precise temperature control. Always refer to the specific instructions of your electric shower model for accurate guidance.
