    5/ 5

    Bought this shower as replacement for a much older version of the Aquastream model that came with the house we bought 7 years ago. The older model owed us nothing more and from experiencing other electric showers over the years, I always felt the Aquastream was the best. These showers while more expensive, are more than worth it. They are safer, I found very reliable, quiet and give a great shower. Getting the installation right is key to long life with these, and issues with water supply to the unit and pipe setup to deliver this is key to keeping the shower running well for years. Only slight niggle I have with the newer shower is slight audible hum from the transformer (old one did not have this hum) - should it get more noticeable I will be in touch with Aqualisa for a replacement. Overall I'm very happy with this shower unit and would highly recommend it to anyone.

    Ordered online as a first time purchase from you. Ordered on a Friday morning, delivered Tuesday morning. Price was best I could find online and some £200 cheaper than catalogue retail price!! Delivery was hassle free and trackable even down to being able to check online that the fitter had received it and signed for it at our house while I was at work. This item was highly recommended by our bathroom fitter as a quality product with easily available spares. A splendid upgrade from our old Mira mixer beast. That's what I call good old-fashioned service!!!

    I purchased this item on the 31st July 2020 and this shower was a direct replacement for an earlier model Aquastream some 20 years old. Ordering this item from Plumbworld was simplicity itself and the whole transaction took a matter of minutes, the package was well packed and arrived on time. The Aqualisa Aquastream was fitted and working within an hour and a half bearing in mind the pipe work and electrical system was already in place. The instructions supplied were very easy to follow. I have no hesitation in recommending this very fine shower.

    I'd consider this an excellent product as a concept. I personally struggled with the final pipe push fit connection and hoped the rubber seals were water tight, which as it happened were. The reliability is to be seen with these over time. I think I'd preferred a compression with olive final connection like they have on other larger units. I do like the compact system and do realise the water pressure is less than a bar from this gravity system. Customer loves it , and that's what matters. Danny , installer!'

    I bought this to replace an older model of the same shower. The new model is a quieter pump, has excellent water pressure and easier to control temperature dial. The shower unit certainly has a flimsier plastic box and control dial than the previous model however that does not detract from the positive benefits over the old model. We have no regrets upgrading to this model and used the existing old units shower head bar and clamp rather than disturb the tiles in the bathroom by fitting the new one.

    So far, been really happy with both the product & service. Ordered on-line, product arrived very promptly, with good notification from Plumbworld. Product seems very well made, quite small, & very quiet in operation compared to my last unit. The first (lower-power) setting is little more than a normal shower pressure, but will be good when I don't feel like the force given by the higher setting! Overall, very happy, & would highly recommend both the product & Plumbworld.

    Excellent Power Shower, I bought the Aqualisa Aquatstream thermo to replace a Mira Event XS which we had for 20 yrs. It is our first Aqualisa and I am not disappointed when compared to the Mira: pump pressure and water volume are exceedingly better; motor and pump are noticeably more silent; 12 volt system is infinitely safer than 230v.; 5 year warranty! The shower experience, if you like pressure and water volume, is at least 25% more enjoyable than the Mira Event XS.

    I first bought the Aqualisa Aquastream 20 years ago and was so impressed with the power of this shower when I had to replace it about 9 years ago I bought another one. Just purchased my 3rd one . I live in a very hard water area and what I like is that you can actuallly replace every part of this product if you want to repair it . However after average of 9 years it was time to replace rather than repair . Excellent power and flow patterns to give a good shower

    Shower arrived on schedule. I have uppacked it and it appears to be complete. However I am now awaiting the arrival of my plumber to install so I hope he will agree that all the bits are there. Congratulations to Plumbworld on its follow up of customers orders.How satisfying to have a company provide a high level of costomer care. Result is that I have already recommended Plumbworld to three friends Keep up the good work.

    I was very dubious about buying a shower as I knew nothing at all about them and, to be honest, I was not sure I even wanted a shower. This was ordered at the recommendation of my plumber and can I say I could not be more happy. The order process could not have been easier and the speed of the delivery amazing. I am more than happy with both my shower and also with the service that I received from plumbworld
