Thermostatic Stable Gauge

Precise temperature control

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 hot and cold water offsetting the everyday changes in water pressure experienced in most family homes.


Only a cold water supply required

Electric showers are by far the most convenient to install. They connect to a cold water supply only and not to your boiler, warming the water using an element inside the shower. So if you're worried about your brother, sister, partner or anybody else using all the hot water in the house then this electric shower is certainly for you. Because no matter how much you us it, it won't run out or let you down when it comes to heat.

Mira Advance Care Visual & Audio Enhancements

Visually & Audio Enhanced

Simple day-to-day activities such as showering shouldn’t be seen as daunting and the Mira Advance does it best to make sure it’s not. It features high contract graphics , raised markings and light-touch buttons, all to make things easier for those short on sight or lacking in dexterity. For those hard of hearing it benefits from clear, audible beeps so you know when the shower is on or off plus clicks on both the shower handset and central dial.

Mira Advance Care Maximum Temperature

4 Different maximum temperature settings

With the Mira Advance it’s now even easier to set a maximum temperature. You have a choice of 4 different maximum temperature settings that can be changed at the flick of a switch during installation thanks to the really clever PCB unit.


10mm cable size

The right size cable depends on the kW rating of your shower. The higher the rating the greater the flow of heated water will be, so you need to be sure to choose the correct cable size for your shower. This particular shower recommends using a 10mm cable.

What is limescale?

Sometimes it can be hard to tell if your shower is suffering from a build-up of limescale as most of the damage is done internally. In some cases you will get a chalky residue appearing on your shower head which will be a good indicator that it’s also inside the shower unit.

People living in hard water areas are definitely more susceptible to limescale so it’s critical to buy a shower that can effectively deal with it otherwise you may have to replace your appliances before you think.


How does Mira Clearscale™ help?

Mira have designed their showers with longer heating elements and larger gaps between the coils ensuring that the heating tank produces a consistent temperature and eliminating hot spots which is where the limescale builds up.

Delayed shutdown also assists by flushing out any leftover hot water.


Mira shower heads

The nozzles on Mira shower heads also help deal with limescale due their rub-clean nature. A soft cloth can be used to simply wipe away any build ups keeping your shower head looking clean and functioning perfectly.

    5/ 5

    Having a previous shower made by Mira and lasted many years decided to have another with the same specs. This shower is brilliant for the elderly and disabled person in mind. The thermostatically controlled shower gives reassurance to the user that the right temperature is always flowing without having them hot and cold spikes with what you get with regular electric showers. The extra long shower hose is of real benefit too and different spraying modes adjustable by rotating the shower head. It’s also has an extra loud audio turn on/off sound to help the user aware it’s fully switched on/off. I would highly recommend.
