Aqualisa Aquastream Thermostatic Power Shower with Pump - White & Chrome

Integrated booster pump

The Aquastream comes complete with an integrated booster pump, providing multiple power settings, making it compatible with low pressure and gravity-fed water systems. This clever booster pump uses Aqualisa's patented thermacoil technology helps to give a new lease of life to low-pressure water systems.

Aqualisa Thermacoil technology

Aqualisa’s patented Thermacoil technology is a bi-metallic thermostatic valve that automatically regulates water temperature by adjusting the mix of hot and cold water in response to pressure changes. Originally introduced in the 1970s, it offers reliable, fail-safe showering by shutting off if the water supply fails, preventing scalding or freezing. This ingenious technology is used in Aqualisa's Aquastream showers, ensuring safe and consistent shower performance each and every time.

Did you know...each Thermacoil is wound by hand! This means you can be confident that the quality and precision of the temperature and flow of an Aqualisa shower is as reliable as possible.

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.

18 litres water per minute

The amazing Aquastream has the ability to provide a massive 18 litres of water per minute, allowing you to enjoy a truly relaxing shower experience. That’s a whopping 28% more water than a Mira Vigour or Triton AS2000XT! Uses Aqualisa patented Bi-Metallic Coil technology to ensure the best temperature stability of any power shower.

Aqualisa Aquastream Thermostatic Power Shower - Spray Patterns

4 spray patterns

Featuring 4 brilliant spray patterns, the Aqualisa Aquastream allows you to easily control the spray pattern depending on the type of shower you desire. With light flow for a truly relaxing experience or a more powerful flow when you need a revitalising shower after a long day or night, there’s a setting for all the family.

Eco setting

Included within the Aquastream's 4 wonderful spray patterns is an eco spray that can reduce your water usage by up to 25%. This not only saves you money but it can also help you to save the environment too!

Easy clean nozzles

This brilliant shower head features easy-clean nozzles to minimise the build-up of limescale. Limescale is a bathroom pest and can easily block things like shower heads. However, with easy clean nozzles, you can simply wipe this mess away with a cloth and mild soapy water and continue straight away.

CE marked product

This product has been CE marked to ensure full compliance with BS EN 14428. This means that not only is it suitable for the UK market but it's been rigorously tested for safety.

Gravity Pumped System

Gravity pumped shower

Ideal for homes with low-pressure, gravity-fed water systems, this gravity pumped shower is designed to deliver a strong and consistent flow. Equipped with an integrated pump, it boosts water pressure to provide a powerful and satisfying showering experience, even in properties with traditional tank-fed systems. Perfect for upgrading older plumbing setups, this solution ensures reliable performance without compromising on comfort or style.

    Bought this shower to replace the Aqualisa Aquastream that was in out house when we moved in. It was as old as the house (20 years+) so we thought another one would be a good investment. It's doing a great job so far! Bought this colour option as it was the cheapest. They're not cheap showers, but I think give very good value for the cost. The lady I spoke to at Plumbworld was extremely helpful when I phoned to make sure I was buying the right one.

    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.

    Have had an aquaLisa unit fitted for close to thirty years. This is the third head. One other was ruined by the water company introducing a large amount of gravel into our supply. I think ten years for this kind of unit in daily use by a family is good service. Changing from the very first unit to the later type involved shortening the supply stubs and new fixing holes. Electrically it is unchanged. I regard this as future proofing which is a valuable commodity these days. The shower has always performed well, this latest one is even more powerful due to a new shower head. Very pleased as it was actually cheaper than the unit bought ten years ago.

    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
