Aqualisa power showers
Aqualisa is one of the most established names in British showers, and its power showers are a familiar sight in homes with low, gravity-fed water pressure. The range is best known for the Aquastream, a long-running pumped shower fitted in thousands of homes over the years. That makes Aqualisa as much about keeping an existing shower going as buying a new one: whether you want a fresh Aqualisa or need a spare or a like-for-like replacement for an Aquastream, this is the place to start. As always, the first step is to confirm your water system suits a power shower, and the rest follows from there.
The Aqualisa range and the Aquastream
Aqualisa's power showers are plumbed-in, pumped units for gravity-fed homes, with manual and thermostatic controls depending on the model. The Aquastream is the line most people know: a pumped power shower designed to turn a weak gravity feed into a strong, steady spray, available over the years in manual and thermostatic versions and in chrome and white finishes. Because so many were fitted, the Aquastream is also one of the most common units people come to replace or repair, which is why it sits at the centre of this page.
| Aqualisa power shower | Controls | Notes |
|---|---|---|
| Aquastream (manual) | Set flow and temperature by hand | The classic, widely fitted pumped shower |
| Aquastream (thermostatic) | Holds a stable temperature | Adds temperature stability and a safety stop |
Exact models and finishes change over time, so check the current range above this description for what is in stock, and confirm any specification such as flow rate on the product page. If you are matching an existing Aquastream, note the controls (manual or thermostatic) and the finish, as that helps you find the closest current model.
Will an Aqualisa suit your system?
Like every power shower, an Aqualisa needs a gravity-fed system: a cold-water tank, usually in the loft, and a hot-water cylinder. The pump boosts that stored water to a forceful flow. If you have a combi boiler or high-pressure mains, a power shower is usually not suitable, and an Aqualisa electric or mixer shower is the better fit instead. This matters whether you are buying new or replacing an Aquastream, because the system has not changed even if the unit has.
On a combi or mains system, see Aqualisa electric showers or Aqualisa mixer showers. Not sure which system you have? The power showers hub has a quick compatibility check.
Aquastream spares and replacements
If you already own an Aquastream, the good news is that it is often repairable rather than a write-off. Identify your exact Aquastream model from the badge or the manual, then match the part, commonly a thermostatic cartridge, a pump component, a hose or seals. If your model is old or the parts are no longer made, a like-for-like replacement that lines up with the existing pipes and cable keeps the work to a minimum. Either way, you are not stuck just because a single part has worn out.

Aqualisa power shower FAQs
What is the Aqualisa Aquastream?
The Aquastream is a long-running Aqualisa pumped (power) shower. Many homes have one, so it is a common candidate for spares or a direct replacement. Like all power showers, it needs a gravity-fed system with a tank and cylinder.
Can I still get Aquastream spares?
Often yes. Identify your Aquastream model and find the matching spare, or choose a direct replacement if parts are scarce. See power shower spares and the spares and replacement guide (both linking when live).
Does an Aqualisa power shower work with a combi boiler?
Usually not. Power showers need a gravity-fed system with stored hot water. On a combi you already have mains pressure, so an Aqualisa electric shower or mixer shower is the right choice.
Do I need an electrician to fit an Aqualisa power shower?
Yes, the pump needs an electrical connection, which a qualified electrician should make to meet bathroom wiring regulations. The load is far lower than an electric shower, but the connection still needs to be done safely.
Is the Aquastream thermostatic?
Some Aquastream models are thermostatic, holding a steady temperature and adding a maximum-temperature stop, while others are manual and let you balance the temperature yourself. Check the controls on the specific model, and if you are replacing one, matching the control type keeps the shower familiar to use.
