Description
The Aqualisa Aquastream Thermostatic Power Shower is engineered specifically for gravity-fed, low pressure systems — delivering powerful, consistent shower performance where mains pressure is not available. The integrated booster pump is built directly into the unit, eliminating the need for a separate pump installation. Thermostatic temperature control maintains your selected temperature and protects against scalding. Supplied complete with a 90mm Harmony shower head (4 spray patterns including eco) and adjustable shower rail. BEAB and CE approved. Available in three finishes.
⚠️ Gravity-fed systems only. This shower is designed for low pressure gravity systems (max. 1.0 bar). It is not suitable for combi boilers, mains pressure, or unvented systems. If you are unsure of your system type, please contact us before ordering.

Frequently Asked Questions
What is a power shower?
A power shower is a thermostatic shower unit with a built-in electric pump that boosts water flow from a gravity-fed (low pressure) hot water system. Unlike an electric shower — which heats cold mains water — a power shower uses your existing hot and cold water supplies and amplifies the flow using the integrated pump. Ideal for homes with a cold water tank in the loft and a hot water cylinder where natural water pressure is low.
Is this shower suitable for my system?
The Aquastream is designed exclusively for gravity-fed low pressure systems with a maximum inlet pressure of 1.0 bar. It is not compatible with combi boilers, mains pressure systems, or unvented cylinders. If you are unsure of your system type, please contact us before ordering.
Does this shower need a separate pump?
No — the booster pump is integrated directly into the shower unit. No separate pump installation is required, making it simpler and more cost-effective to install than a standard shower with an external pump.
What is included with the shower?
The shower is supplied complete with the thermostatic power shower unit, a 90mm Harmony shower head with 4 spray patterns, and an adjustable shower rail.
What finishes are available?
White (£949), White/Chrome (£949), and Satin Chrome (£1,009). Select your preferred finish from the dropdown above.
