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.


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.


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.

    5/ 5

    My existing Mira Advance shower stopped working in the morning, no hot water and it was at least 9 years old as it was here when I moved in. Ordered it from Plumbworld in the morning after to speaking to someone at Mira to get the newer replacement model. Even with next day delivery it was still cheaper than Screwfix and Toolstation. Next day DPD delivery (thank you for NOT using Evri), email gave me a 1 hour delivery window. I arranged for someone to arrive 30 minutes after delivery slot. DPD delivered within slot time, old one out, new shower in. Everything lined up, even the screw holes to hold it on the wall and best of all the water inlet just screw back in. The shower was back up and running with hot water. The shower is easy to use. Press to start, it beeps and when it gets to the set temperature it beeps to tell you you can get in now. So say you have it at #8 it beeps when it up to temperature. Can't fault any part of the process. Great service, great price, great DPD delivery and a great shower.

    Our Mira Advance shower finaly gave up last week after 15years of faultless service (RIP).What make to buy next was never in question,it had to be a MIRA.We searched the web and found that MIRA still made the same "Advance Thermostatic 8.7kw Model" that we had and Plumbworld had the best price beating the nearest best price (Screwfix) by nearly "£30.00",now thats a LOT of money to save on one item and that included VAT and FREE delivery as well.I needed to check out some further information which the sales team sorted straight away and were very polite as well.I recieved regular email updates from plumbworld and also from the Courier service along with a great tracking service. The new Shower was delivered bang on time by a very smart and polite driver.Well done Plumbworld for providing a GREAT service,your at the top of our list for our future plumbing needs. Thankyou+++10/10

    Was looking to replace an antiquated shower. Looked on the Plumbworld website and they had the perfect replacement! No messing with extra wiring or plumbing. This shower just fitted perfectly! Looks good and also the best price on the internet! Why shop around after reading this? If I he website can’t help then you can contact them for extra information and reassurance.

    We had been without a shower for a week, and in a house with 4 women/girls, that was a catastrophy. We found the exact replacement we needed, it wasn't the cheapest, a famous online retailer was £10.00 less, but couldn't delivered for nearly a week. Having the shower delivered the next day, exactly on the time range promised was well worth the extra. Thank you..

    Bought to replace a previous Mira shower that we have had for 20+ years. This shower fitted exactly into the space without the need to re-drill any holes or replace any tiles. The rail & shower head were updated to a high standard. We are really pleased with the quality & performance of this product & trust that it will last as long as its predecessor

    Replaced aging Advance Mk1 made in 2004 for a direct/sourced replacement. Installation matched original fixings and operation controls easier than old model consequently satisfies fully 'Form, Fit and Function' in every way. Many thanks for rapid response and delivery from order, good company to deal with.

  • Brian
    5/ 5

    Bought to replace a very old Mira Advance shower. Connected straight up to the original pipework (unit is plumbed outside of the shower cabinet so pipes are rigid in the wall) just half a hole out on the mounting locations. Easily fixed and unit works fine. Hope it last's as long the previous shower.

    Could not fault the service I got from Plumbworld ordered on the Sunday at 1.00 pm and received next day a 11.30 am. Fitted straight out of the box and working by the afternoon. Very good price paid for this shower Thankyou for your very prompt service. Satisfied customer.

    I was particularly impressed by the prompt delivery as I had already booked a plumber to do the job. I have been using the shower now and it does an amazing job! I just do not want to come out of the shower anymore! Thank you so much Plumbworld!

    We ordered the shower and it was delivered within a couple of days on a day that suited us. It is yet to be plumbed in by our plumber friend but look forward to it being so in the New Year. Would use Plumbworld again definitely.

    Our previous Mira shower packed up after about 9 year's heavy duty service, and this one was our chosen replacement. Several improvements over the previous model, and, as I would expect for the price, another quality unit.

  • Peter Fulham

    Bought this to upgrade my old Mira unit and glad I chose another, which was reasonably easy to fit straight in place of the old one. Nice big shower head which can be adjusted to your needs. Fast delivery, very satisfied

    This is the third Mira electric shower that I have had and from early signs it is going to be just as good as the other two. They are reliable and allow you to get the water temperature right

    Originally, I bought this from Screwfix but was delivered with a crushed box. Quite poor. Bought from Plumbworld, perfectly delivered and protected - and £36 cheaper. Not yet installed.
