The Aqualisa Siren SL Exposed Mixer Shower Chrome is a thermostatic mixer shower unit, designed with panache, built to perform and engineered to last. The metal exposed mixer valve has a minimalistic aesthetic guaranteed to complement bathrooms both contemporary and traditional, while its straight-edged and streamlined design only add to the appeal. Meanwhile, it integrates eco-friendly features and thermostatic technology to deliver a product that not only looks great and works like a dream, but is kind on the environment, as well.

One of the most versatile models on the market, the Aqualisa Siren SL is compatible with all kinds of plumbing networks, including gravity, boosted gravity, combi and balanced high-pressure water systems. Capable of handling pressures of 0.1 bar right up to 10 bar, it also incorporates wax-stat technology which means that it constantly manages the temperature and flow of water, allowing you to indulge in the perfect shower at the drop of a hat and without having to worry about any unwanted fluctuations in temperature or pressure.

All Aqualisa Siren mixer showers are complemented with a fully adjustable Harmony shower head and hose, resulting in the minimum of fuss in getting your shower up and running. The head comes with four different spray settings to allow optimal customisation of your showering experience, with one of the settings engineered to deliver environmentally-friendly results. In fact, the eco-spray setting has been proven to save up to 25% more water than other alternatives, which will save the planet a valuable resource in the form of H2O and save you a valuable resource in the form of money off your next energy bill.

Constructed from brass with a sleek chrome finish, the Aqualisa Siren SL is built to last. In fact, Aqualisa are so confident in the durability and reliability of the shower unit that it comes with a five-year guarantee on all parts and labour, while the accompanying Harmony handset has its own two-year guarantee. With that in mind, you have complete peace of mind that the future of your family’s showering needs is guaranteed for many years to come. Simply put, it’s the cutting edge of style, performance and robustness, all rolled into one environmentally-friendly package.

Shower Kit

Shower valve only

This product is only the exposed shower valve. We do this to allow you to mix and match your choice of shower hose, riser rail and handset for a shower that’s completely unique to you.

Aspire & Siren Valve Replacement



Replace An Exposed Shower With An Aspire DL Or Siren SL

Replacing an old, exposed shower (like a Mira Excel) doesn’t need to be difficult when you upgrade to one of Aqualisa’s new generation mixer showers. The exposed models of both the Aspire DL and Siren SL shower range feature adjustable inlet centres, ideal for refurbishment projects where a degree of flexibility is required.

Thermostatic Stable Gauge

Maintains Constant Temperature In All Conditions

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 mix of hot and cold water offsetting the everyday changes in water pressure experienced in most family homes.

Harmony Ecospray

Water Saving 'Eco' Shower Heads

Some water-saving shower heads aerate the flow of water to deliver the ‘illusion’ of bubbles, but Aqualisa weren’t prepared to compromise the way your shower looks or feels. Harmony™ heads use intelligent design to deliver a fuller spray whilst allowing you to make water savings of up to 25%.

When the ‘eco’ spray on a Harmony™ shower head is selected, the shower head concentrates and angles the spray from its two outer rings. The result is a spray pattern that is refreshing and generous yet incredibly efficient in terms of water consumption

Harmony Shower Heads


4 Spray Patterns

The new Harmony head for Aqualisa showers is perfect for showering any time of the day. With 4 to choose from you’ll always have the right combination of invigoration or relaxation.

Who needs a spa day when you’ve got a shower like this?

Harmony Antitwist


Anti-Twist Shower Hose

Twisted shower hoses restrict the water flow from your shower.  With Aqualisa anti-twist technology they are no longer a problem. You can take your shower head out the holder without it flailing around and trying to escape! Anti-twist technology ensures the best possible water flow and extends the life of your shower hose.

Aqualisa Harmony Rub Clean Nozzles


Rub Clean Shower Head Nozzles

With a Harmony shower head the days of soaking in vinegar to remove limescale are gone! The brilliantly designed nozzles can simply be rubbed clean with you hand to remove any residue that may have built up.


5 Year Parts & Labour Guarantee

  • Mrs S Maidment
    5/ 5

    Purchased this shower for our granny annexe, couldn’t be more pleased, easy to use and regulate for an elderly relative, the fittings feel really good quality and shine up brilliantly after use. Would definitely recommend this shower.

  • Adrian Prismall

    The shower arrived the next day, it was well packaged. The instructions were clear and the fitting, even for someone with only basic DIY skills, was relatively straight forward. All in all I am very pleased with the shower.
