Aqualisa Siren Mixer Showers

Yes. Siren thermostatic mixer showers are designed to work with a wide range of systems, including combi, gravity, boosted gravity and balanced high‑pressure systems. Bear in mind they are mixers, so they need both hot and cold feeds; if you have a cold‑only supply you would need a different shower type. If you're unsure which system you have, check your boiler or cylinder setup and match it to the list above.

The concealed valve sits behind the wall for a minimalist look, while the exposed valve sits in front of the brickwork and becomes a visible design feature in chrome. If you want a sleek, pared‑back bathroom choose the concealed option; if you prefer something that shows the valve as part of the décor and gives easier access to controls, the exposed version is a good match. The two Siren models reflect these styles: SRN001CA is the concealed mixer and SRN001EA is the exposed mixer.

Thermostatic temperature control keeps water at a steady temperature even when someone else in the house uses water, so you won't be hit by sudden hot or cold surges. That steady output is especially important for children and vulnerable users who could be harmed by abrupt temperature changes. The Siren range's thermostatic valve gives you reliable comfort and added safety during daily use.

The Harmony adjustable handset has four spray patterns that use different parts of the head (outer, middle and inner) for varied sensations, plus an eco spray that uses the outer rings to increase coverage while cutting water use by up to 25%. The handset also has rub‑clean nozzles, so limescale wipes away quickly and performance stays consistent. You might use the eco setting for a quick morning rinse and switch to a fuller spray when you want a stronger, spa‑style experience.

Siren showers come in a chrome finish that is both classic and hardwearing, and the rub‑clean handset nozzles make routine cleaning straightforward. Aqualisa has been making showers since 1977, which speaks to long experience in design and reliability. The range sits in a mid‑price bracket, such as the exposed Siren SL is around £301.99 and the concealed version about £351.99, giving you thermostatic safety, adjustable spray modes and a quality finish for that price.
