Magni-flo Technology

Mira created Magni-flo™ technology to allow you a powerful, revitalising shower even with water pressure as low as 0.1bar. The clever technology optimizes the internal valve waterways, giving you up to 3 times more water flow, automatically enhancing your shower to give you the ultimate showering experience.

Coolshield Technology

There’s nothing worse than accidentally brushing against your shower and scalding yourself on the metal from the heat of the hot water. So, Mira carefully and cleverly created their fantastic ‘Coolshield’ technology to put a stop to this. The ‘Coolshield’ technology eliminates any accidents by keeping the shower valve cool regardless of how hot you have your water, keeping your showering experience safe and scald-free which is especially important for young children.

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.


Solid brass body

Has your shower been the same one since you moved in several years ago? It’s probably about time you gave it an update, especially as it's something you use every day. This shower valve has been constructed from a good quality solid brass, which is designed to be long-lasting and finished to a high standard.

    5/ 5

    We replaced our electric shower with this product conected to cold water mains and hot water feed from combi gas boiler. Our bathroom fitter said it was straightforward to install and it works exactly as advertised. Firstly it should be noted we are in a Low Preasure Water area and both the rainfall head and other smaller head provide excellent water preasure. We love the way you easily switch between each head and the valve turns the one head off immediatly so no dripping. The temprature selection is easy to use and we can adjust between preferences. The most important element is the mixer. Here it manages to keep the water at a constant temprature even when the toilet is flushed or someone uses a tap downstairs; yes there is a drop in pressure (both the shower continues to provide an adequate flow) however the temprature remains constant. The finish is also very good, it looks more expensive than it is and it is very easy to keep clean. We also like the fact the rainfall head extends out horizontally further than most other brands or Mira models which means you do not need to stand close to bath taps. Only minor comment is the shower does drip slightly for a minute or so after being turned off (from whichever was the last selected head). This is really not an issue and we find it stops pretty quickly unlike showers I have had in the past. We give this shower 10/10 on all fronts...especially price from this supplier.

    I've just switched from an electric shower to this which runs off a 30kw combi and the difference is ridiculously good...so much heat and pressure, it was well worth the investment (boiler was also new at time of install). The rainfall head is bigger and has less pressure than the smaller head, as you would expect, but it is great for that 'immersed' feeling. The small head packs a punch of pressure-great for my wife who suffers with shoulder problems. It was easy to adjust the temperature limiter to give us maximum temperature after the plumber had gone. Speaking of the plumber, he was so impressed by this shower that he asked where I got it from and how much because he wants one in his house! I should also say how well it was packaged and the fact I could choose my delivery date was a bonus. I would definitely recommend this shower and plumbworld to anyone.

    Our Darryl shower finally started to leak recently and needed replacing. Although I could not find a similar tower to replace it, having successfully fitted a Mira shower for my Sister in Law about 12 years ago (which is still functioning extremely well), I decided to look at Mira Thermostatic Mixer showers. Having to fit it into and existing tiled shower cubicle with no easy rear access for the pipework, made preparation for the pipework and fitting the shower much more difficult than the first system I had installed. That said it is now compete and working and is excellent. Another superb product from Mira.

    This is a truest wonderful shower combination. The waterfall is like being on the beach in Bali when your eyes are closed. Lovely way to wake up in the mornings. The shower head is really powerful and massages the stress right out of you too. Useful for spraying the bath area one your finished too. Best Buy I’ve made in a long time. Prompt delivery and great price too.

    Have used these showers many times and always recommend them to clients smart all in one unit never had a problem, Mira is a name that has been on my list for over 40 years and still recommend them this was the cheapest on the web so had to purchase great delivery time as expected without delay Thanks Plumb world / will use again thanks R.

  • Terry Lenton
    5/ 5

    Very pleased with product quality and ease of fitting. Wanted the shorter pipe for the installation and contacted customer service to purchase. Was told was out of stock so tried local suppliers and internet. Unable to source pipe elsewhere so went back to customer service who were now able to supply and did so free of charged.

    As you would expect from Mira excellent quality and the £30 cash back is a bonus. You have to wait 30 days to claim it but they will remind you if you visit the website. We have used Plumbworld previously and always find them very competitive, good customer service and fast delivery.

  • Martin J Gaskell

    I was looking for a shower with the waterfall feature and decided on this one. Plumb world was the cheapest on the net at the time, I’ve never used them before but will definitely recommend the service I had from them and the shower is excellent quality and easy installation

  • K flanagan
    5/ 5

    The shower is fantastic, looks more expensive than it was. I read the reviews before purchasing and I am over the moon with it. Smaller head is very powerful and as expected the big head is a rainfall shower so not as powerful but is a nice experience under both

  • R. Velders

    Looked at these in the shop, and found a better deal here at Plumb World. No hassle with the installation, and now we can enjoy a lovely shower again. Thermostat works great and we love the big shower head at the top.

  • Helen

    Just what I was after, great price and cheapest price by far on Plumbworld...even better with the £30 cashback that was offered by Mira too! Delivery was extremely quick. For the price, the shower is excellent.

    Replaced a 10year old Mira shower with this newer model and loving it so far. Great temperature, pressure and the deluge head is great. Installed by a plumber but was very simple.
