Also referred to as: handset/shower rose/drench head
There are a few types and features of this often overlooked shower part, not to mention many styles!
Where possible we always advise to replace your shower head with the manufacturers original part, this is to maintain the intended performance and design of your shower. We stock a huge range of heads from most common showers.

Not able to source the original or a suggested replacement?
Make sure to choose a shower head based on the type of shower you have (electric, mixer, power). This can be filtered using our website filters.
What are the different types of shower head?
- Fixed overhead ceiling drench heads/roses
- Handheld shower heads. These are usually found on the shower head holder (aka riser/clamp bracket) on a fixed rail or in a holder on the bath mixer itself.
It's almost always the hose which sits into the holder/slider, rather than the shower head.
- Wall mounted shower heads, fixed onto the pipework directly or on an extended arm. Sometimes these feature a swivel ball joint to adjust the spray angle.
What to consider when choosing a head?
- Is the head suitable for your shower type? Use the filters on our website to select the applicable options. e.g Mixer, Electric.
- The number of spray settings. You can use the website filters to select this.
- The style of the spray settings. Look in the product description for more information on this where applicable.
- How does the head connect to your shower/pipework? Some fixed heads use different connection types such as push fit, compression fit, 1/2inch BSP or a non standard fitting or adapter.
Almost all handheld shower heads will use a 1/2" BSP male fitting to the shower hose. This is fairly standard. You can see more information on choosing a hose here.
- Pressure compatibility for your shower. Do you have a high or low pressure system? For more information on this see Types of Household water systems
- Material/colour: You may want a specific finish to go with your other fittings. Chrome and white are the most common, with gold heads being less sought after over recent years. Some shower heads are also constructed out of metal instead of plastic.
Have a Trevi Boost? (Not to be confused with a Trevi Therm). It may need this specific head due to the way the shower operates.
The importance of choosing the correct shower head
Electric showers have a Pressure Relief Valve (PRD or PRV) within them. These are designed to fail when the pressure within the shower builds up. The symptom of a failed PRD is water pouring from the bottom of the shower, rather than from the head. One reason these fail is due to an unsuitable head being fitted.
If the shower head is not specifically designed for an electric shower, quite often they have flow restrictors built in. This will create a build up of pressure in the shower due to a restriction caused by the head. The PRD then fails in order to prevent damage to the shower. Water then pours from the PRD's outlet rather than the outlet leading to the shower head.
The PRD would then need to be replaced, as well as finding an appropriate head before the shower can be used again. On some showers, the heater tank itself needs to be changed entirely, which can be an expensive fix.
This problem can be prevented by using a head suitable for your shower. For more information on Pressure relief devices and how they fail, see Video: How to change a pressure relief device (PRD)
