    We love this shower and it is the 3rd one we have purchased.
    Great economy setting and good water flow.
    Stylish looks too.

    Thank you it’s easy to install, it’s good for small family and for money but water pressure is a bit slow

    A good shower and extremely easy for a diy fitting.
    I would’ve given 5 stars but rail for holding shower head is a bit fidgety and plasticky

    Good quality electric shower from a well respected brand Mira. Easy to install and use. Great features such as the air boost feature. Stable temperature for a non thermostatic shower, like all of this type of shower the temperature fluctuates seasonally as is dependant on the cold water temperature going into the shower. Perfectly normal for this type of shower.
    Very happy with my purchase, have had no issues whatsoever.

    We bought this after our 10 year old Mira Sport shower have up. It was installed by a plumber but it took him minutes to do. Would recommend.

    Sport Max 10.8 kW Electric Shower was money well spent. I was told to go for the lower KW but so pleased with the 10.8 KW for the strength of the flow, its very relaxing.

    We already had an exact same Mira shower which had served us well for many years but finally packed up. So we decided to buy the exact same one again as it had been really good plus the holes were in the right place for fitting. Would definitely recommend

    I bought this product to replace its predecessor which had failed after over 10 years usage.

    The fitting, in my case, was trivial. The electric and pipe fittings were identical, so no plumbing work was required. Just one of the securing screws was in a slightly different position and that involved drilling one hole and inserting one of the supplied rawlplugs.

    This product has obviously been developed over the past 10 years or so because it is MUCH improved. The temperature stability and water flow is much better and more predictable. The air boost is fantastic and really makes the shower feel much more powerful, without actually increasing the water flow.

    I use this shower every day and I am really happy with the price and performance of this product.

    Compared to my old Triton shower this has been a revelation. It is powerful compared to others I have tried and also very quiet which is great when people are having early morning showers. I would certainly recommend this shower to others. I would not try to fit this without a certified plumber due to water and electrics!

    This is a great electric shower. We have two, and they’re very reliable. We’ve just replaced one with same model after five years of multiple daily use (and that was only because of our having used an inappropriate shower head which caused the heater chamber to blow a safety valve – beware glitzy social media ads for shower heads – they can’t be used on electric showers). The only negative is that the supplied support for the shower head requires you to drill holes, so no use for glass shower cubicles.

    Such a brilliant shower. Very easy to fit (was my first one) with clear instructions and a handy template.

    The water temperature is way better than my old Mira Zest and the air boost make a real difference to the flow. Honestly, it’s not that noisy, either.

    Love how the buttons are lit and how the shower gently powers down when you hit the power button. Totally worth paying the extra to get a quality shower.

    Easy to install where old shower had been. Covered exactly. Only 1 new screw needed. Shower head wonderful with different settings. Hit water just about instant, so no hopping about waiting fir it to warm up. Just love it. A vast improvement on the old shower, which was a Mira Sport. Boost makes some difference, but I don’t think it’s necessary. Enough pressure without it. Would definitely recommend this model.

    I replaced a 15 year old Triton Belize with this Mira Sport. I didn ‘t realise that Mira have the water inlet on the opposite side (left) to Triton so had to re-do the pipe route. It must all line up perfectly! Once I had done that and used PFE tape around the olives and threads to stop leaks it all worked as specified. Great shower and wife happy with the Air Boost feature which works on all settings. Now to see if this one will last 15 years. If so it should outlive us both.

    I ordered this shower to replace the old Mira Sport which has lasted 13 years. It was easy to replace , only one fitting screw was different and that was the bottom one which needed a new hole. I was pleased with the old one but this one is even better. Excellent water pressure and controllable temperature. Very efficient, I’m delighted with it. I hope it lasts as long as the old one.

    Golden Review Award: 3 From Our UsersWith the flow valve on our 2013 9.8 KW Sport Max starting to leak due to a split in the case, I decided to replace the whole thing rather than repair it due to its age. Had intended to get like for like, however I noticed the supposedly more expensive Airboost model was listing on Amazon 30 cheaper, albeit in 9.0 KW (20 saving over the standard 9.0 KW model), so I thought why not.

    When it arrived I was pleased to see it was a direct swap, as the case fixing holes were in the same place, along with the electrical and water feed connection points.

    Found an error in the instructions, as it indicated you needed to connect and test the water connection first, however on doing this water poured out the hose outlet. Found I needed to fully assemble it and turn the electrics on first before turning the water on.

    Noticed while setting up this shower it runs far hotter than my 2013 model, maybe because its new; the old one needed to be on high to get to a decent temperature, whereas the new one gets there in eco mode. However the water flow with this airboost is noticeable weaker, possible to do with the required diffusers for the airboost function in both ends of the shower hose causing a slight restriction. The airboost function itself seems a bit of a gimmick too and a little noisy and not worth paying more for over the standard model in my view.

    Therefore I’ve given the airboost 4 stars, as apart from the slightly hotter water temperature, overall its not as good as the standard model IMHO, so I’m glad in our case we paid less for it.

    Golden Review Award: 2 From Our UsersI replaced an existing Mira that was beyond repair (it never broke case cracked over time). The new shower fitted the existing water and power feed (Mira is very good on this) had to drill three new holes but covered by shower. The new shower is very elegant and works extremely well, bought the 10.8 KW model and the water output is much better than the previous 9 KW Sport. The air pump really helps with rinsing long hair as my wife & daughter will testify. A word of warning to make it work properly it must have the air pipe alignment part fitted on the shower end. When I installed I could not find it but as a checked the box the next day to register and save the instructions I found the part. I simple unscrewed the hose pushed the inner air line down and pushed the airline into the alignment part and screwed back in carefully to ensure a good seal and it worked brilliantly. My daughter has it on all the time as it increasing the flow and makes it a big hotter and the agitation works really well to rinse the shampoo and soap over much quicker. The shower head supplied is miles better than previous versions. Highly recommend this shower.

     United Kingdom

    Golden Review Award: 2 From Our UsersThe shower works fine. The temperature control is not as fine as I had expected but once set seems to hold the temperature well. Of note is the fact that this is a higher rated current device than a 7.6W shower so you may need to upgrade the electricity feed to the shower unit. Also, the same duration of shower will cost you more with this unit than a lower wattage (obvious if you think about it).
    Other than that, it was relatively easy to install as a replacement for my previous (Mira) shower unit and I would certainly recommend it.

    Golden Review Award: 3 From Our UsersWe bought this shower because our Triton failed (would only deliver scalding hot or freezing cold water) and we’d had a Mira in one of our previous homes. It was easy to install – I called a plumber who did it for us for 30 – bargain! Good shower but I wish we’d gone for the more powerful version; however we couldn’t do that because the existing wiring wouldn’t support it. It does the job though and is good value for money.

    Golden Review Award: 3 From Our UsersAs expected, very good quality and easy to install. Just needed to add a compression elbow joint and a small length of 15mm copper pipe to connect to the existing pipework that had a Triton shower with push fit connector. Fitted over the same area as the old Triton so previous holes drilled through the tiles were completely covered. Gives ample hot water and the air boost system definitely works giving much more of a power shower feel. You need to change the riser rail and use the hose and shower head supplied as they have the air hose running internally to provide the boost function. Mira have thought of everything as the riser rail wall connections can easily be adjusted to fit into the existing holes drilled for the previous rail. A competent DIY’r should be able to fit in half an hour.

Just hoping that this one will last as long as the previous one. We were looking forward to trying the boost function button which is a new addition to our old shower unit. I think its a bit of a gimmick and don’t bother using it for the majority of time, its very noisy as well. A negative for the new shower is that the hose seems shorter than the other hose we had. I am happy with the shower in general though

    Golden Review Award: 2 From Our UsersThis shower is the best electric shower I have ever had, actually I have been so impressed with it I have just replaced it with the identical model. Why change something when it’s perfect. It is quiet, really important when you have a small bungalow and work early shifts. It has a max boost which feels like a hot jet of water on tired bones. Go for the ’10 W’ it’s worth the extra power. Yes it’s expensive but my last one lasted 8 yrs until the thermostat went so thought I would replace due to safety because of age but the hose, head and arm still look as new so saved those until they need swapping over. Worth every penny. When it comes to a shower you definitely get what you pay for.

    Golden Review Award: 2 From Our UsersThis was easy to install as I was taking out a Mira (over 10 years old) but the wiring and pipe work were in the same places. This unit did have one fixing screw in a different place from the old one but had a slightly bigger case so the old unused hole was covered
    The one small thing I am disappointed about is this updated version detects water pressure and won’t start unless is detects that pressure, which is a safety feature but we used to run our shower from a pump and tank which meant however many other taps or toilet flushes took place the shower was unaffected. Unfortunately we are now back on direct feed which means these things do all affect the shower. There is an air feature that is meant to make it feel like there is more water being delivered but I feel it just makes it more noisy and didn’t notice the difference. This can be switched on or off so we just don’t use this feature

    Golden Review Award: 2 From Our UsersI bought this secondhand, but unused and in the box, so I certainly cant argue with the price I paid. Was very easy to install and fit. All the functions work as stipulated in the manual, and although not the most powerful of showers, it certainly gives a nice shower and does it’s job. It also looks very nice once fitted, looking expensive. Once you have set your temperature, it keeps at that said setting, so not had any shocks with the odd annoying hot or cold spurts during my shower like my past showers have given us. Would certainly recommend this product.

    This one looks great- sleek and modern
    The output flow is good for an electric shower but buy the 10.5 kw to get this output. We replaced a 8.5 kw shower and had to have the electric supply cable upgraded by an electrician. Well worth the extra work and cost.

    Golden Review Award: 2 From Our UsersExcellent product. Have used Mira showers for decades.
    This recent but was too replace a previous Mira shower which wad fitted in 2000 … so the last one lasted 19 years!!!
    Easy format to use.
    Pull cord switch to turn on electric.
    Check heat dial is where you still want it.
    Then just press the chosen flow button.
    I really like the simple heat dial which is so easy to use.
    What I also really like is that I don’t need my glasses to see how to operate it!!! There is just a sizeable on flow button, a heat dial and finally an off flow button. Easy peasy.
    My husband was able to fit it in under half an hour, which included taking the old one out, if you use a reputable electrician it shouldn’t really take them any longer!!! … unless of course, there is new pipework or electrics to adjust or install, but even then it’s all standard stuff, so an hour max, I would say.
    Our order came promptly as promised. Excellent buyer/seller transaction.

    Bad Points. The airboost is useless and completely pointless, its just a gimic they use to sell more and its noisy so takes the relaxation side away from the shower. Would have liked a strong jet nozzle on the shower head instead of the rain storm one.

    Golden Review Award: 3 From Our UsersHaving had 2 Mira Sport 10.8kW showers previously, I was happy with the performance and quality of the brand. This particular model is better than the ones I had before. The controls are very easy to understand; it has an ‘Eco’ setting which is quite adequate in warmer weather, and the usual ‘low’ and ‘high’ settings. Where it scores extra points is for the additional ‘air boost’ facility, a separate button which intensifies the force of the shower.
    I have given it 5 stars for ease of installation, although we had a plumber to do the job. He had no problems, and finished the work quite quickly. What seemed good to me was that the position of the fixings for the new shower were the same as the old one.
    I would definitely recommend this shower.

    Golden Review Award: 13 From Our UsersI am not sure what to think about this shower. I had a mira azul before – fantastic shower initially but went downhill and after 5 years the thermostat had gone. I was reluctant to try another mira but thought it might be easier for plumber to install the same make so I went for this one. It’s great to have a shower back but the azul was far better initially. There’s also been times when the temperature is too hot/cold and it can be difficult to get the setting right. Small movements on the dial seem to make a big difference on temperature. For the price, if expect better temperature control. However; generally nice shower – the airport feature is lovely and do happy to have a shower back. I just wont be happy if the quality doesnt last like with the azul. I have had this shower a couple of months so far.

    The air boost makes a big difference. Really pleased with this shower. Would have been better if it was multi-fit, because it was a pain having to move everything to fit it, but in the end I think it was worth it. Why on earth they don’t make all showers multi-fit is beyond me!

    Golden Review Award: 5 From Our UsersHave had this shower a year now and am so delighted with it. I used to have an old Mira which had such poor flow but this is amazing. The treat of having the extra air boost is lovely.

    Temperature control is easy and it has been lovely this hot summer to jump in on normal temperature and just hit the eco button for a blast of cold water. I love the fact that you have four settings on the shower head so dependent on your mood you can have the usual flow or you can get a concentrated flow but then add the air boost to these and it makes it even better. I am on metered water so I dont feel guilty using the boost as I know it is not using any extra water.

    Had to renew the wire which fed an 8Kw Triton before with a 10mm cable and the pull switch.

    To replace an old electric show you cant get better than this one. It will always be an electric shower. You’re not gona get near the throughput of a mixer but this is the next best thing.

    Shower head is well made and provides a brilliant coverage setting which helps forget its not a mixer.

    Airboost is a bit of a gimmick. Dont really notice much difference but my son thinks it makes all the difference 🙂

    Golden Review Award: 9 From Our UsersWe had the predecessor, 10.8kW unit and apart from one of the three screw fixing positions which required a new hole, it is easy to fit. The air boost feature is good and the flow and temperature is still adequate.

    I can understand some of the negative comments on the manufacturer, as our previous unit developed a fault and required repairing but we found that they fixed the issue and we got about 8 years of constant heavy use from it, until the pump unit leaked. Rather than repair it we decided it was better long term to replace the whole assembly.

    This shower taps off directly from the towns main supply and this gives us 2 independent shower units at home, so if we have a problem with the hot water supply or the header tank we have a complete backup. Hindsight is always a powerful tool. We would definitely recommend this to anyone.
