Have no idea how to install a shower? So, read on and find out!

How to choose the right shower?

Before thinking about installing a shower, it is necessary to choose the product correctly. And contrary to what many people imagine, showers are not all the same.

One of the first points that need to be considered is your comfort and well-being, choosing a device that offers a good water jet and temperature control. There are those who prefer a cold bath, and there are those who never deny a warm bath!

And, remember to also define whether your shower will be solar, electric or gas powered. This will depend on the installation available in your home, with electric models being the most common.

The gas shower has some interesting positives, such as higher water pressure and energy savings. But on the other hand, it uses more water than electric showers, as it takes longer to heat up.

For those who want a more sustainable option, you can opt for solar showers, but they can only be used if the building has a solar heating system.

Another important point is to assess whether you are going to buy a wall or ceiling showers. Wall-mounted ones are the most common and there are models with or without a tube. The longer the tube, the greater the distance between the water jet and the wall. So, if your box’s space is small, choose a model with a smaller tube!

The ceiling shower, on the other hand, has the advantage of being able to be installed in the center of the box, but the installation is more restricted and the model can only be used when the hydraulics come from the ceiling – thus, this shower requires the installation of the lining to hide the piping .

You will also need to consider:

  • The voltage: there are 110 and 220 volt showers – and they need to match your house’s voltage;
  • The power: models with power less than 5400 watts are cheaper and more economical in terms of energy consumption, but they tend to burn more easily. Durable, powerful products tend to have power greater than 5400 watts;
  • The characteristics of your home: when the shower installation is done in houses without good pressure or that only have a valve in the bathroom, the recommendation is a pressurized shower with a large spreader. In apartments that have good pressure, it is possible to invest in a common shower with a small, medium or large spreader;
  • The economy: it is possible to find super economic options in terms of electricity and water consumption, but the value of the product tends to be higher. If there are several residents in the house, beware of very large spreaders, as they tend to waste more water;
  • Shower flow rate: is the water supply capacity, ranging from 6 to 60 liters per minute, depending on the model and water pressure. Models with higher flow rates require an adequate pressure, because if the pressure is lower than that recommended by the manufacturer, the jet will be weak. For Plumbing Services Consult Here

Care to be taken when installing a shower:

Before even starting the shower installation, it is important to take some precautions. The first, without a doubt, is to check if the electrical voltage and power of the appliance are compatible with the wiring and circuit breaker in your home.

Also, don’t forget to turn off the main switch on the electric power board or the circuit breaker responsible for energizing the environment where the showers will be installed. Also check that the water valve that feeds the shower pipe is properly closed.

In short, you must:

  • Close the bathroom water valve;
  • Open the shower valve to eliminate pipe residues and then close it;
  • Turn off the main power switch or circuit breakers;
  • Check with the tesla switch that the current is no longer running.
  • Check that the circuit breakers and the gauge of the electrical supply wire are in accordance with the power of the shower (as specified in the manual);
  • Make sure the device’s ground wire is connected to a grounding system.
  • Tools used
  • Before starting a shower installation, set aside and make sure you have all the necessary tools, which are:
  • Phillips screwdriver;
  • stairs;
  • screwdriver;
  • test key;
  • thread sealing tape;
  • insulating tape or electrical connector;
  • pliers;
  • drill for fixing the shower head (if necessary).

Shower installation: step by step:

That’s it, now you have everything you need to start your shower installation. So, just follow the step-by-step instructions below!

Step 1: start shower installation
After turning off the electricity and closing the water valve in the bathroom, use the thread seal tape to seal the water inlet from the shower. This is the entrance on the wall, over which the shower pipe will be placed.

Step 2: Install the pressure reducer
Water pressure varies in each property. If there is very high pressure in your home, it is recommended to install the pressure reducer, it will ensure the right pressure for the showers to work, increasing the product’s lifespan. Usually, this item comes with the showers and is installed in the water inlet of the equipment.

Step 3: Fix the shower
Now, fit the shower into the water inlet and turn it clockwise to secure it in the pipe. Just be careful not to push too hard, as the barrel is a fragile piece.

Step 4: connect the wires
Connecting the shower’s power wires to the mains is not a complicated task. After all, each wire must be installed according to its color.

Therefore, light blue is the neutral wire, green or yellow is the ground wire and red, black or brown is the phase wire. Remember to insulate the wires using electrical tape or electrical connectors.

Step 5: Fit the accessories
This is the simplest step, as all you have to do is attach the hose, shower head and shower support.

Step 6: test the shower
Before turning the circuit breaker on, let the water flow through the shower for about 30 seconds. This step is essential in order not to damage the shower and not burn the resistance.

Step 7: turn on the electricity
Ready! Shower installation is complete. Just turn on the electricity and enjoy your hot shower, placing the temperature selector in the desired position.

Bonus: important tips and guidelines

As you have seen, shower installation is not a complicated mission. But still there can be some “surprises” and it is important to know how to deal with them.

Ground wire:

By standards, the ground wire must always be yellow or green. But in some electrical installations this equipment may be lacking. In this case, the recommendation is to install the ground wire to increase safety when using the shower. You will need around 2 meters of wire and a connector that must have a rod with a 4 mm cable (the measure needs to be enough to connect the rod and the shower).

If you don’t have experience with electricity, it’s best to look for an electrician, like the Getninjas, to do this job. But if you want to give it a try, you’ll need to bury the rod in a part of the ground and leave a small part outside (about 10 centimeters).

Then run the wire through the tubing that goes into the bathroom – if you can’t run it using the tubing, use a gutter to hide it and run it through the outside.

Phase wire:

To find out which is the phase wire of your electrical installation, the tip is to use the test key. Only the hot wire will turn on the test switch light, what does not light is neutral and the wire of different color is ground.

If in doubt which cord is which, read the shower manufacturer’s recommendations – there is usually information about these points on the product packaging or in the manual.


It’s common for some people to burn out the shower heater while trying to install it. For this not to happen, leave the shower again at cold water temperature (summer). This way, when you turn on the shower to test it, the resistance will not be triggered. Only after leaving about 30 seconds of water to drain you should change position.

But if you don’t follow this guideline and burn the resistance, you don’t need to buy another shower, just change it.

To change the resistance, you will have to use a screwdriver to open the shower. Then, disconnect it from all electrical wiring (with the circuit breaker turned off). Unscrew the air cap and remove the cap. Be careful not to damage the rubber that is between the chamber and the lid (because this will cause future leaks).

Observe or photograph the shower resistance before buying a new one and correctly analyze the position where it is, to make the installation correctly. The longest stretch between the contacts will be applied for most of the resistance and the shortest for the part corresponding to the size.

Using pliers, remove the old resistance and replace the burned part with the new one, paying attention to leave it in the same position. Then reassemble the shower.

Make the shower installation as instructed and, before turning the circuit breaker, remember to let the water fall for about 30 seconds. This will remove the air and fill the shower chamber with water, preventing the new heater from burning.

Okay, now you can turn on the circuit breaker, change the temperature and use your shower!
