Understanding the Functionality of Mixer Showers: A Comprehensive Guide

If you are considering purchasing a new shower or planning to install one in your home, you may be wondering about the various options available. One of the most popular types of showers is the mixer shower. A mixer shower blends hot and cold water together to produce a water stream at a specific temperature. In this comprehensive guide, we will explore the functionality of mixer shower and how they work.

Types of Mixer Showers:

Firstly, it is important to understand the two types of mixer showers. The first type is a manual mixer shower that has two separate controls for hot and cold water. You need to adjust the temperature by selecting the correct amount of hot and cold water. The second type is a thermostatic mixer shower that regulates the temperature automatically. A thermostatic mixer shower consists of a thermostatic valve that monitors the temperature and adjusts the water flow accordingly.

The Components of a Mixer Shower:

A mixer shower has two main components: the valve and the showerhead. The valve controls the temperature by blending hot and cold water together. It is important to select a valve that matches the flow rate and pressure of your water supply. The showerhead produces the water stream and can vary in design, from fixed overhead showerheads to detachable handheld ones.

Installation and Maintenance of Mixer Showers:

Mixer showers can be installed by a professional plumber or as a DIY project. If you choose to install it yourself, it is important to follow the manufacturer’s instructions carefully. Mixer showers require periodic maintenance, such as cleaning the showerhead and descaling the valve. It is important to check for any leaks or drips and replace any worn-out components.

Advantages and Disadvantages of Mixer Showers:

Mixer showers have several advantages over other types of showers. Firstly, they are versatile and can be used with any water system, from low-pressure gravity-fed to high-pressure combi boilers. Secondly, they provide a steady stream of water at a consistent temperature, which can be adjusted to suit personal preferences. However, they do have some disadvantages. For instance, manual mixer showers may require several adjustments before achieving the desired temperature, and thermostatic models can be costly.

Safety Considerations:

Finally, safety is a crucial aspect to consider when installing and using a mixer shower. Thermostatic mixer showers are safer than manual ones because they automatically adjust the temperature and prevent scalding. It is important to test the water temperature before stepping into the shower and to set the thermostat to a safe temperature.


In conclusion, mixer showers are a popular choice for homeowners because of their versatility and ease of use. Understanding the types, components, installation, and maintenance of mixer showers can help you make an informed decision when choosing a shower for your home. While mixer showers have several advantages, it is important to consider safety aspects and select a model that suits your water system and preferences. By following these guidelines, you can enjoy a comfortable and safe showering experience.
