What Is a Mixer Shower Valve and How Does It Work?

Ever been in a shower where the water suddenly turns freezing because someone else turned on a tap in the kitchen? Or worse, it suddenly scalds you? If you've faced that, you already know why a mixer shower valve is more than just a plumbing part; it's a must-have for a comfortable, reliable shower experience.
At its simplest, a mixer shower valve blends hot and cold water together before it reaches your shower head, delivering water at your preferred temperature every single time. And when it’s part of a concealed thermostatic showe, you get the added bonus of a sleek, modern look. No bulky fittings, just smooth surfaces and smart controls.
At Jaquar UK, we help you create a bathroom that feels thoughtfully designed and truly personal. From elegant shower arms and sleek shower heads to over 12 colour finishes and expert-led 3D design consultations, we’re here to bring your vision to life with style and precision.
How Does a Mixer Shower Valve Really Work?
When you switch on your shower, cold and hot supply lines feed into the mixer valve. Inside, a thermostat senses the water temperature, mixes it accurately, and delivers it through whichever outlet you prefer, be it an overhead rain shower head, a handheld wand or body jets.
If pressure drops or spikes, the valve automatically adjusts. No nasty surprises here. That’s the genius of the concealed thermostatic shower setup: hidden mechanics, smooth control, and reliable water, every time. Jaquar’s thermostatic shower mixers are offered in multiple finishes and outlet combos, all working on this safe, steady principle.

Putting It All Together in Your Bathroom
Think of the mixer shower valve as the hidden shower-hero. Once it's tucked behind your wall in a concealed thermostatic shower, all that’s visible is a clean, polished faceplate. Then your shower heads and shower arms carry the water in style. Whether you're diverting between a rainfall top spray and a handheld wand or simply enjoying a steady cascade, the mixer valve handles the temperature, and the pleasure is all yours.
