Best thermostatic shower in the UK | Comparative Table

Thermostatic showers made by trusted manufacturers are more expensive than non-thermostatic ones, but they have several advantages. The risk of scalding is greatly reduced with a thermostat temperature limiter that keeps constant at 38°C. A mixing valve blends hot and cold water and keeps it consistent even if someone else in the house turns on a faucet or flushes a toilet.

Trusted Manufacturers of Thermostatic Showers

• Hansgrohe & Grohe are well-known German manufacturers that have been producing sanitary fittings for around 90 years
• Mira Showers brand is owned by Kohler Mira Ltd, the UK-based shower equipment company with a long history. In 1936, it launched the world's first thermostatic mixing valves. Among the Mira Thermostatic showers, there are models with Magni-flow technology that delivers up to 3x more flow, even at low pressure, and a digital shower with a wireless controller. 

When it comes to prices, a Thermostatic mixer from trusted manufacturers will cost you around £130, while Thermostatic Shower Systems with large rainfall upper showerheads are more sophisticated thus their prices start from £300.

If you need an electric thermostatic shower the prices start from £150 and depend on the power (from 8.5 kW up to 10.8 kW), design (plastic or glass), limescale protection technologies, and a number of showerheads Single handheld or Dual with a rainfall upper showerhead.

Testing & Customers Reviews

We asked our expert Peter Kim to make some experiments with a thermostatic mixer to find out how the temperature reacts to shut-offs or flushing of water in the toilet. He measured the temperature using a connected temperature sensor and a multimeter.

Peter Kim: "I want to tell you about the Hansgrohe Ecostat Thermostatic Shower and do some experiments.

We will change the running pressure of cold and hot water and see how this will affect the temperature. We will measure the temperature using a connected temperature sensor and through a multimeter. The temperature is shown here as slightly lower than the real one, but the dynamics can be tracked. We will change the pressure with the help of a toilet, by turning on the cold and hot water in the tap and by completely shutting off cold and hot water. Let's see how the mixer reacts to this.

And so we turn on the water. We have two handles here. One is the change in water pressure. The second is the set temperature. It's set to about 38 degrees. Feels like 36-37 degrees there. Our temperature sensor shows approximately 30-31 degrees. Accordingly, with good changes in pressure in the network, the thermostat twists the water, but it is felt, yes, it has become a little warmer or a degree colder. But there is no such thing as before when I ran out of the shower because it was very hot or very cold. No need to twist now. Everything is kept at a comfortable temperature.

And so let's now see how the temperature will react to the flushing of water in the toilet. We see an instant rise in temperature to 34 and back to normal. Approximately on sensations, it lasts within one and a half seconds. First, a small jump to a non-burning, not high temperature and then returns to its place. Now let's turn on the cold water. We'll see how it reacts. Similarly, the increase is slightly more, up to 35 degrees. As I said, there is low pressure in the network, and the temperature could not fully return back, but it is kept within reasonable limits.

Now I will turn off the water. There was a jump in cold water, the temperature dropped and returned to normal again. Now I'll turn on the hot water. Now the temperature should drop first. Yes, it fell and returned. I turn off the hot water. Now it will rise and come back. And it returns. Accordingly, now we will carry out the last test, we will completely block cold and hot water. Now we have a cold one running. And we block. As you can see, we turned off only cold water, but the mixer also turned off the hot one. Now we will not burn as it could be before. Now we will conduct a reverse test, turn on the cold and turn off the hot water. The result is similar. Hot water and cold both blocked, although we blocked only one.

If we need to finish showering, then we just turn on the cold water and the water goes. But you can freeze. As a result, the screen justifies itself by 100 percent. I was afraid that one or two seconds, as stated in the specifications, is a long time. But in fact, if earlier the difference was even if for 1-2 seconds, but there was very hot water or very cold, now it is literally 2-3 degrees and it feels like slight warming of the water, and then it normalizes. Those are not so sharp drops, not so big.

The washing is very comfortable. The unit itself is very nice. Chrome doesn't scratch. The handles are of good quality. Nothing backlashes. Enamel does not crack. Accordingly, the kit has everything you need. You can easily install it right away and it will work. Check valves for cold and hot are already built-in. Hot on the left, cold on the right. It remains only to put filters on the input, but I did not set it myself. It's been doing just fine for almost a year now."
