Power Showers vs Electric Showers

There’s some slight confusion online about the difference between a power shower and an electric shower. Mainly, because the power units also use electricity.

What is a power shower?

A power shower takes water from hot and cold feeds. It then boosts the pressure using an electric pump to create a more powerful spray. So, these showers DO use electric, but they’re not the same as traditional electric showers when it comes to heating.

What are thermostatic power showers?

A thermostatic power shower utilises the above (hot and cold water feeds, as well as a pump), but has the thermostatic mixing valve to reduce the chance of sudden temperature fluctuations. These fluctuations in temperature come from a sudden drop in water pressure (i.e. another appliance is being used such as a washing machine, resulting in low pressure).

And did you know it also stops scalding and freezing?

What are electric showers?

Electric showers are a bit different. A traditional electric shower doesn’t take water from both hot/cold feeds; it only requires a cold water feed. Using an integral element, it heats water at its source. That means water doesn’t need to be heated by your combi boiler, because all the heating takes place directly in the unit, in the bathroom.

Best power showers for your bathroom in 2021

So below, we’re going to cover our top picks for the best bathroom power showers that use electric pump systems for heating. We’re focusing on thermostatic showers that use an electric pump to boost pressure and flow rate.

#1 – Triton Power Shower

First up, we’ve got the Triton Thermostatic power shower.

Triton Thermostatic Power Shower - SatinIf you’re like me, you’ll be digging through a tonne of shower reviews online, before making a decision on exactly which shower one to buy for you bathroom buy. And when you do, you’ll be pleasantly surprised with the Triton. It’s got one of the highest volume of reviews online, and for good reason, because it’s:

  • Cheap
  • Manufactured by one of the most popular brands in the UK
  • Great for properties with incredibly low water pressure


You’ll find a lot of cheap power showers being offered with ZERO warranty. And, that gives you an indication of what these companies think of their own products. That’s not the case with Triton. They’re a bathroom brand that’s well known for having some of the most durable shower products on the market.

Complete with your purchase of the Triton Thermostatic power shower, you’ll get a 1-year manufacturer’s warranty.

Flow Rate

Like all electric power showers, the Triton has a built-in electric pump that helps to combat poor flow rates on units that are connected to low pressure systems.

Once you’ve got the Triton shower installed in your bathroom, you’ll be getting a flow rate of around 14 litres per minute. That compares to a traditional tap, that produces around 9 litres per minute.

Design And Ease Of Use

Let’s face it, the design of most electric power showers is pretty-basic. There’s nothing special about the Triton, but it’s fairly slimline in comparison to many of the cheaper alternatives.

It utilises a simple push button start, and you’ve got a numbered dial on the front of the unit to adjust temperature.

Temperature Control

The thermostatic mixing valve on the Triton is able to regulate temperature effectively. If you do experience a sudden drop in water pressure, you won’t be subjected to freezing or scalding water. The TMV on the Triton is able to regulate temperature to within 2 degrees of whatever you’ve currently got it set at.

Basically, the fluctuation in temperature is going to be unnoticeable, thanks to the built-in thermostatic mixing valve.

And, there’s even a temperature stop, to ensure that you don’t accidentally turn your shower heating up too high.


You want your shower to last, and there are certain precautions that many brands don’t take. And, that means their showers aren’t reliable.

One of those things is an auto-shutdown. If the shower water supply falls too low, the pump in your power shower is going to work overtime. Eventually, it’s going to burn out, and you’ll need a costly replacement, so this is a nice type of safety feature.

The auto-shutdown feature recognises when pressure gets too low, and turns off the shower, so the pump isn’t being overworked.


There are, certainly, cheap products out there that are slightly less expensive than the Triton, but not by much. Triton sell their products in such high volume, that many other top manufacturers struggle to compete on price. And, because there are so many online suppliers, you can usually find the Triton for WELL below the RRP.

What’s Included

You’ll get a shower head included in the purchase price, and that’s got 5 different spray power settings to choose from. That’s going to be connected to a stainless steel hose, that’s anti-kink and it’s been reinforced to improve durability.

And, to fix it all together in your bathroom, you’ll also get a flexible riser rail kit.

Who Should Buy The Triton power shower?

If you’re looking for a basic looking but well-priced shower product from a leading manufacturer; this is the one for you and your bathroom.

You’ll get durability, flexibility in terms of installation area, and a great flow rate of around 14 litres per minute. And as we’ve mentioned, there’s a tonne of companies offering up the Triton well below the RRP.

#2 – Mira Vigour Power Shower

Looking for a direct alternative to the Triton? The Mira Vigour shower is exactly that. Everything from price through to flow rate is similar, so it really just comes down to the design you prefer for your bathroom.

Mira Vigour Thermostatic Electric Power ShowerWarranty

Like Triton, you’ll get a solid 1-year warranty on your Vigour from Mira. However, what Triton don’t offer currently, is any additional protection.

Mira offer a range of different warranty packages, allowing you to extend the warranty on your shower for an EXTRA 1-3 years.

Flow Rate

Just as you get with the Triton TMV shower, you’ll get a high flow rate of 14 litres per minute from the Mira Vigour.

Design And Ease Of Use

The design does differ in comparison to the Triton. The Mira Vigour is more minimalist; they’ve cut back the size of their controls.

Temperature Control

But, like the Triton you’ll have simple to use controls allowing you to adjust temperature. And you’ll have a built-in “safe” maximum temperature, that comes factory set.

Using the temperature dials, you’ll be able to get hot water up to 65 degrees.


There’s no need to prime the Mira Vigour, but there are removable filters that are designed to be maintained. This is their way of prolonging the life of your shower.

Throughout the UK there are low, moderate and hard water areas. The harder the water, the more minerals it contains. And, it’s these minerals that lead to limescale build-up on both the shower door and tiles as well as in the shower head itself. This can block up a power shower, leading to expensive repair bills, or even a shower replacement.

By integrating these removable filters, limescale is reduced and any debris in water is caught, rather than blocking up the shower.


As we’ve mentioned, this is a direct competitor to the Triton. The current RRP of the Mira Vigour is around £250.

Like the Triton, there are a lot of sellers offering the Mira. And, that means there’s a price war; it’s rare that you’ll pay the full RRP.

However, it’s worth comparing the deals DIRECTLY with the Triton. It’s much more likely that you’ll find the Triton cheaper than the Mira, even though that actual-RRP is the same.

What’s Included

As far as accessories go, You’ll get your electric power shower, a showerhead with 4 levels of adjustment (that’s 1 less than the Triton, by the way), installation instructions and a riser kit.

Who Should Buy The Mira Vigour?

This is a direct competitor to the Triton mentioned above, so that’s what you should be comparing it against.

At my time working in a plumbing/bathroom merchants, we sold a tonne of both. They’re both reliable showers, are priced similarly, and have the same flow rate.

We’d recommend both electric showers and that means, it comes down to the design type you prefer for your bathroom.

#3 – Bristan Power Shower

If you’ve purchased bathroom products and accessories in the past, there’s a good chance you already know about the Bristan brand. Bristan are one of the leading shower, tap and bathroom accessory manufacturers in the UK.

Bristan Hydropower Thermostatic Electric Power ShowerAnd, the Hydropower 1500 power shower is one of their most popular showers. For good reason too, it’s similar in quality to both the Triton and Mira, yet the RRP sits well below both.


As we’ve mentioned above, the warranty on offer from a manufacturer gives you a good indication of how reliable they think their products are. After all, they don’t want to be footing the bill, so won’t offer a warranty at all if their products are not durable (i.e. cheap brands).

And, even though the Bristan Hydropower is cheaper than the Triton and Mira, the standard warranty is better. You’ll get 1-year for the Triton/Mira. For the Bristan Hydropower? You’ll get 2-years for parts, and 1-year for labour.

Flow Rate

The biggest downfall of the Hydropower is it’s flow rate. The Mira and Triton both get 14 litres per minute. You’ll get just 10 litres per minute with the Bristan; so it’s definitely not the most powerful shower out there.

The question is, does it matter? Power showers are designed to be used in low pressure water systems; they’d probably struggle to deliver 2-3 litres per minute (9 litres per minute is about the average for a tap).

So, although the flow rate isn’t the “best in class”, it’s above what’s provided to most shower units throughout the UK.

Design And Ease Of Use

This is one of the minimalist power showers you can get for your bathroom. And that makes it perfect for most bathrooms but in specific, those that struggle for space. So, if you’re in a small bath, or tiny shower enclosures, then this is going to help make that enclosure feel a little bigger than it is compared with other showers on the market.

You’ll get Bristan’s updated riser rail, a vast improvement on the three showers the Hydropower replaces (New Team N1000XT, NT1000XT Power Shower and Showerforce SF 1000 XM).

As with the Mira and Triton, there are simple push button controls for the shower, including one for ECO (improved water efficiency). And, a nice touch is the fact that the Hydropower has rear pipe entry, meaning there are less ugly fittings exposed in comparison to other units available in the UK.

Temperature Control

You’ll get the standard dial for temperature control, but being thermostatic, you’re protected if there’s a sudden fluctuation in water pressure or heating. The thermostatic valve in the Bristan Hydropower is one of the best; it will be able to regulate the temperature between -1-+1 degree of the temperature original set.


The warranty here speaks for itself. It’s the biggest warranty on offer from our “best power shower” list; 2-years for parts and 1-year for labour. So, you can be sure this type of shower is going to last.


If you’re looking for a cheap power shower for your bathroom, this is also where the Bristan comes up trumps. Its RRP is well below the Mira and Triton.

But, unlike the Mira and Triton, it’s unlikely you’ll be finding deals much below the RRP. The Hydropower is already competitively priced, so it doesn’t seem like retailers have much margin to move on price.

What’s Included

You’ll get a shower head that’s got 3 spray settings to adjust. That’s bolted to the wall with their upgraded riser rail, which looks more stylish than previous models. And, you’ll get all the installation instructions and fittings needed to fit this into your bathroom.

Who Should Buy The Bristan Hydropower?

In my opinion, all things told, this is the best power shower on this list.

It offers excellent savings when compared with both the Mira and Triton shower options. And, whilst the 10 litres per minute flow rate looks low (compared with the 14 of the Mira and Triton), that’s still a higher flow rate than the majority of properties will have in the UK.

If you’re looking for a cheap power shower from a leading brand, that’s durable, has excellent online reviews and a big warranty, the Bristan Hydropower is definitely the one for you.

Power showers companies

So, those are our recommendations for the top selling electric showers available in the UK. But, what if you’re not seeing a design you like, with a suitable flow rate?

There’s a lot of companies offering cheap power showers. The problem? They’re exactly that; cheap. Cheap showers tend to have not just low, but inconsistent flow rates, and prone to low pressure. And, there’s a good chance they’re not going to look as good or have the reliability factor that you’ll get from leading manufacturers.

Below we’ve curated a list of the top power shower brands available in the UK. So, if a unit on the list above doesn’t stand out, you won’t go far wrong by buying a power shower from these companies.

Best shower brands for smart consumers to buy

  1. Triton
  2. Bristan
  3. Mira
  4. Creda
  5. Aqualisa

Shower installation costs

So, you’ve bought your new shower unit with all its accessories. Now what? You need to get it installed. The cost to install and fit your shower in your bathroom is likely to be in the region of £150-250. That’s going to be the price excluding the shower itself, and any additional parts and tools (pipework and additional fittings).

The price differential comes into play depending on where in the UK you are, and the complexity of the install and fit. For instance, if this is a new bathroom without pipework, that’s going to take more time (and cost more) than swapping out an existing unit with one that bolts straight onto the existing cold/hot water feeds.

  1. I like the sound of the Bristan due to option the rear entry pipe as I would like to hide the piping behind a panel and have a fixed ceiling head with this system ,Is that possible?

  2. Having just moved house we have inherited 2 electric showers Aquatronic 3+. The power of both of these showers is different…one reasonable but the other a waste of time. Therefore am looking to replace both with a much more powerful showe. We do not have a Combi boiler. Just a condenser boiler.Therefore am I correct in assuming that it would not be possible to have a Thermostatic power shower installed? Please…what would you recommend?

    1. I would get a local engineer to come for a quick check-up and “audit” of the installation for a more detailed look at it. Answering your question is not just a simple yes and no. Other things may cause you trouble. Going for better thermostatic power shower is a good idea, but first check with your installer you don’t have other issues to fix first.

  3. I have had my power shower more then 10 years when I put it on and turn it of the water stops but the motor carry on I have to keep turning it on and of do I need a new unit

  4. Hi, We have inherited an Aqualisa Aquastream MK2 power shower, which now needs replacing. (It has gravity fed hot and water pipes, plus booster pump)We need to put in an equivalent which will cause minimal disruption, to the rest of the bathroom. One option is to get the Aquastream Mk3-which might be most straightforward, but I wondered if you can recommend a different make (a bit cheaper) that might be a good match? I don’t really know where to start with a decent equivalent. Many thanks

  5. We are in the process of getting our loft converted. We were going to get a 9kw electric shower (as our cylinder is too small to supply two showers) but apparently our water pressure is a little on the low side (1.0 bar). Would a power shower solve these issues for us or would the small cylinder still cause problems? Thank you!

  6. im looking to replace a creda power shower with top right hand feed (hot left , cold right) can u suggest one that has same fittings
