Power shower spares & replacement parts
A power shower that has lost its heat, its flow or its temperature control has not always reached the end of its life. Often a single worn part is the culprit, and the right spare brings the whole unit back for a fraction of the cost of replacing it. The key is to match the part exactly to your brand and model, because power-shower parts are rarely interchangeable. This page helps you shop spares by brand, recognise the common parts, identify the right one for your unit, and know when a spare is no longer the sensible choice.
Shop spares by brand
Spares are organised by brand and model, because each maker builds its units differently and the parts are specific to them. The most commonly needed are for the big names, Mira, Aqualisa (including the long-running Aquastream) and Galaxy, alongside other brands. Start from your brand, then narrow to your exact model, since even two showers from the same maker can take different cartridges or pumps. Availability depends on the model and how long it has been in production, so the current range is the best guide to what you can get.
Common spares
Most power-shower repairs come down to a handful of parts. Here is what they do, so you can recognise the one you need:
- Thermostatic cartridge. The valve that controls and stabilises temperature. A common cause of a shower that runs hot and cold or stops holding temperature.
- Pump or impeller. The part that boosts the flow. If the shower has gone weak or noisy, the pump may be at fault.
- Hose and handset. The flexible hose and the shower head. Easy to replace when they leak, clog with limescale or crack.
- Seals and O-rings. Small rubber parts that stop leaks. Cheap, and often the fix for water escaping where it should not.
Limescale is a frequent background cause, especially in hard-water areas, so a part that has failed early may point to scale worth clearing at the same time. Fitting a new part into a scaled-up unit can shorten its life too, so it is worth descaling the showerhead and hose while you are at it.
Identify the right spare
Matching the part to your unit is the step that gets the repair right first time:
- Find the brand and model on the badge on the front of the unit, or in the manual.
- Note which part has failed, using the common-spares list above as a guide to the symptom.
- Match the specific part for that exact brand and model, since parts are rarely shared between models.
- If you are unsure, photograph the unit and the old part and ask our team to confirm before you buy.
Any work involving the electrical supply should be left to a qualified electrician; many spares, such as a hose, handset or cartridge, are straightforward, but the electrical side is not a DIY job. Taking the old part with you, or a clear photo of it alongside the model number, is the surest way to get an exact match first time.
When a spare won't do
Sometimes a repair is not the right call, and it is better to know that before spending. If your model is discontinued and the part is no longer made, if several things have failed at once, or if the unit is simply old and tired, a direct replacement is the more sensible, longer-lasting fix. A new like-for-like unit also resets the warranty and can quietly upgrade your controls. The honest rule: one available part on a sound unit, repair; scarce parts, multiple faults or old age, replace.
If replacing makes more sense, see replacement power showers for like-for-like units, and the spares and replacement guide weighs up repair versus replace (both linking when live). For parts beyond power showers, see shower spares.
Spares FAQs
What spares can I get for a power shower?
Common parts include thermostatic cartridges, pumps and impellers, hoses, handsets and seals. Availability depends on the brand and model, so identify yours first to find the exact part that fits.
How do I find the right power shower spare?
Identify the brand and model from the unit's badge or manual, then match the specific part. If the model is discontinued or parts are scarce, a direct replacement may be the better option, so see replacement power showers (linking when live).
Can I fit a power shower spare myself?
Many spares, such as a hose, handset or cartridge, are straightforward to fit by following the manual. Anything involving the electrical supply should be left to a qualified electrician. If in doubt, a plumber can fit most parts quickly.
Are power shower spares universal?
No, they are almost always specific to the brand and model. A cartridge or pump from one shower will not usually fit another, so always match the part to your exact unit rather than buying a generic equivalent.
How long do power shower parts last?
It varies with use and water hardness, but cartridges, pumps and seals are wear parts that may need attention over the years, sooner in hard-water areas. Descaling regularly and clearing the showerhead helps them last, and a tired part is often a sign the whole unit is ageing.
