Shower valve only

If you've got your eye on a particular new shower head, (you know, the one with 4 spray modes and a massage setting!) then you don't want to be wasting money by buying a whole new shower set. With this product you are only buying the shower valve so you can mix and match your choice of shower hose, riser rail and handset for a shower that’s completely unique to you.


The Aqualisa Siren SL Concealed Mixer Showers represent the cutting edge in modern mixer shower valve design. With the bulk of the valve concealed behind the shower wall, only the single-lever tap and shower head are visible, meaning it’s as discreet as it is durable. What’s more, it hasn’t just been designed to impress and engineered to last, but also with optimal performance in mind. The unit is compatible with all kinds of plumbing systems and incorporates thermostatic technology, meaning a steady stream of the desired water temperature is always on hand.

The single lever control is the only element visible in the cubicle – aside from the shower head itself. This not only adds a touch of understated class to your showering experience by eliminating unsightly valves and pipework, but makes controlling the flow and temperature as easy as possible. Simply turn to the left for hot water, right for cold. With wax thermostatic technology monitoring and managing the supply of H2O to the unit at all times, there is no chance that you’ll be subjected to unpleasant blasts of an undesired temperature or lapses in pressure, regardless of activity elsewhere in the house.

The Aqualisa Siren SL mixer showers come equipped with a Harmony shower head and hose, capable of spraying in four different settings to suit all tastes and needs. What’s more, the eco-spray setting has been specifically engineered to be kind on the environment – tests show that it’s able to save up to 25% more water when compared to a regular setting. That’s not only good news for Mother Earth, but also good news for your back pocket, since you can save a packet on energy bills.

The unit is compatible with every kind of plumbing system and can handle a wide range of pressures, from 0.1 bar to 10 bar. Constructed from solid brass, the Aqualisa Siren has been built to last – and its manufacturers are so confident in its ongoing performance that they’ve included a five-year guarantee on the valve itself. For the accompanying Harmony shower head and hose, a two-year guarantee is available as standard. What are you waiting for? Upgrade your showering experience in style with the Aqualisa Siren today!

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.
