    There was an Aqualisa Aquastream when we first moved in and we were delighted with it until it needed replacing a few years later. Now that the replacement has packed up, I decided to go back to an Aquastream. Easy to fit with a low voltage transformer rather than a direct mains connection. The clean lines of the Aquastream make it a smart addition to the shower. The new style shower head gives a wide selection of spray patterns and works well on normal output. When the boost is selected the strength of spray is terrific! Quiet in operation compared to the previous shower we had. New style hose in white is also an improvement over the usual silver ribbed version. Delighted to have gone back to Aquastream and its even better than before.

    I bought this shower as a like-for-like replacement for a 13 year old Aquastream shower. Unfortunately the drill holes are in different places and the top fitting of the pipes are also different. The template supplied is fine if fitting new pipes, but having existing ones still in place makes fitting rather tricky. As for the quality of the shower - I am VERY happy. Very quiet motor and 4 different shower head options make this an excellent power shower. Great communications combined with very prompt delivery and a more than competitive price means that Plumbworld will probably be the first place I look in future. b

    I bought this shower unit to replace an older Aqualisa Powerstream. The original shower was 10 Years old and had started to leak. I had no hesitation in buying another Aqualisa partly because I thought it would be a straight swap for the original. The new shower was an upgrade to a thermostatic control and a two stage pump(low and high speed) It didn't line up with the existing screws but the plumbing was identical. the whole job was complete in Half a day. This shower is a great all in one unit and delivers power to challenge more complicated installations at an acceptable noise level.

    I had an original Aqualisa Aquastream Power shower for 25 years and when it died I replaced it with the new model. Fitting was not straight forward as the top inlet pipes on the new shower were much wider apart so the pipework had to be altered and the fixing holes for the body also had to be redone and as the body is smaller than the original it was difficult to cover the original fixing holes. That said the new shower is fantastic and the temperature control redesign is much better.( I hope it lasts as long as the original one. lol.)

    When we had our bathroom fitted,about 12 or 13 years ago,our fitter recommended we have an Aqualisa shower as they are very reliable,easy to fit,and spares are readily available.It lasted 8 years before anything went wrong and I got the part on the internet ,had it fitted and it lasted another 4 years.It finally died the other week so we bought another Aqualisa shower,had it fitted and hope that this shower lasts as long!

    This shower was purchased as a replacement for an earlier Aqualisa shower purchased some 13 years earlier. The original shower had been in constant use over that period but recently had begun to run out of life. We thought it had done extremely well over its life and were happy to purchase another. we trust that this will be even better than the earlier model. Great showers!

    We already had an Aqualisa shower in our bedroom so when the Mira packed up in the bathroom, there was only one choice for the replacement, yes, another Aqualise.We are very pleased with the shower product, it's so quiet and very efficent an excellent choice well recommented, value for money..our second Aqualise was only installed to-day.

    The title isn't a play on words about the product. The shower itself is excellent. We bought this as a replacement for an earlier model Aqualisa that we reckoned had lasted us 12 years. Fitting for us was relatively simple as we reused wiring and pipework, if you're confident with plumbing/electrics this would an easy fit

    I bought this product to replace my previous Aquastream shower which was over 15 years old and I'm really pleased with its performance; the shower is not only more compact and smarter in design but it also runs a lot quieter and I can't fault it in any way.
