Thermostatic Stable Gauge

Maintains Constant Temperature In All Conditions

Standard showers can have hot temperature spikes when others in the house turn on taps or flush the toilet.

Thermostatic control means that this shower will hold its temperature steady at all times. It dynamically adjusts the mix of hot and cold water offsetting the everyday changes in water pressure experienced in most family homes.


The superb Mira Realm combines traditional styling with efficient modern showering performance. It has a stylish classic design complete with a rigid riser rail, hand held shower and deluge showerhead for an experience that satisfies again and again.

Features and benefits:

  • Traditional styling with an all-chrome finish.
  • Temperature stability through thermostatic integration. This keeps the temperature stable throughout the entire shower, making it safe to use for all the family.
  • A maximum temperature shop increases safety.
  • Simple to use with one control for temperature and on/off settings.
  • Includes Mira’s Magni-Flo™ technology to deliver a flow strength that’s up to 3 times more powerful than similar mixer showers – even at low pressure!
  • Choose your experience: Divert the water between the overhead showerhead and hand held shower, or use both heads at the same time.
  • Includes a 210mm single spray deluge shower head and an 80mm single spray hand shower.
  • Showerheads include rub clean nozzles to easily prevent limescale build-up.
  • Works on all water systems and pressures.
  • Covered by a 5-year manufacturer guarantee.

Technical details:

  • Minimum dynamic water pressure: 0.1 bar.
  • Maximum dynamic water pressure: 5.0 bar.
  • Flow rate (at 0.5 bar): 15 litres per minute (combined).
  • Operating hot water range: 50-85°C
  • Recommended hot water range: 55-65°C
  • Water entry: Rising, falling or rear.

    We bought this as a replacement for an old Victoria Plumb shower. We have a low pressure to the shower room and the original one we bought, though saying it was for low pressure, was not performing well. Our plumber recommend Mira as these were better suited. It was installed easily and has transformed the shower experience. The flow is much more powerful and the controls are easier to use. A great purchase end excellent service and price from Plumb World.

    Bought this shower online. No issues with delivery as I was able to choose the delivery date. Arrived well packaged and no items missing or damaged. Plumber installed it for me as changing from electric to thermostatic. This shower is fantastic and really wakes you up with great water pressure. 2 secs and you’re soaked from head to toe! Love the diverter shower head which you can have on it’s own or with the main shower head.

    Purchased to replace a non-servicable unit from a 2nd rate competitor hint: B&...... Item contained EVERYTHING indicated including full instructions and items required to fit - SUPERB! Took 24hrs for a happy-amateur to fit (me). It gets used 3/4 times daily and i have yet to think of a fault/shortcoming with it. HIGHLY, HIGHLY RECOMMENED!

    Excellant product, we bought two of these one for our ensuit the other for the wet room, we coupled them up with a power shower pump, the hand held shower head and the over head can both be used at the same time, otherwise a fantasic sharp spray from one or the other.:-)

    You will not be disappointed with this shower. It performs and looks amazing. My top tip would be to check the contents immediately when it is delivered as you only have a 7 days to return it if it is damaged.

    Good looking shower with simple controls. Had to buy a new shower due to taking out my back boiler so bye bye power shower. Head does drench you with the bonus of the hand held head to reach your crevices, and both will run at the same time...bonus! Not as powerful as my old power shower but a good replacement.

    Straightforward to fit, looks great. However plumber thought the control levers were wobbly probably due to plastic fitting inside
