Whether you're here because your shower has never been quite right or because a swap didn't go the way you expected, you're in the right place.
A shower head is a single fixture, but the right one makes stepping into your shower feel like a small act of self-indulgence every single morning.
And getting there starts with knowing what to look for.
How the head size relates to your enclosure. Whether your water pressure will actually support the one you've chosen. And whether the fitting is something you can do on a Saturday morning or needs a professional.
Once you’ve got all the details, you can focus on finding exactly what you want.

What is a fixed shower head?
A fixed shower head is either mounted to the wall or ceiling rather than on a rail or handset you can move around. So once it's up, that's where it stays.
There’s no fiddling with the angle before you've fully woken up and no redirecting the spray mid-shower and ending up with water all over the floor. You just get in and it works, the same way every time. That reliability is more of a luxury than it sounds.
Wall-mounted fixed shower heads are the most common. They sit on an arm that extends from the wall above head height, angled slightly downward toward you.
If your bathroom already has a wall-mounted shower head, you’re most of the way there before you’ve even picked up a spanner.
Ceiling-mounted shower heads are the ones that make you feel like you’re showering in a boutique hotel.
That overhead flow tends to be wider and softer, more of a wrap-around immersive flow than a directed jet of water. It’s the kind of shower that’s hard to rush!
If you've ever seen a shower described as a rainfall shower head, that's exactly the experience they’re describing.
Getting the size right
It’s easy to fall in love with a shower head online and order it before you’ve measured a thing. Then it arrives, you hold it up, and that excitement evaporates.
The size you barely glanced at on the product page is suddenly the only thing that matters.
Will a new fixed shower head fit my existing shower arm?
In most cases, yes. The vast majority of fixed shower heads sold in the UK use a standard half inch BSP (British Standard Pipe) thread, and most UK shower arms use the same connection. For a like-for-like swap, compatibility is rarely an issue.
But if you're using a shower head from outside the UK or replacing a very old fitting, it's worth checking the thread size before you buy. Sometimes they are different and adaptors are widely available if needed.
The diameter of the shower head needs to work with the size of your shower enclosure.
Go too large in a compact enclosure and the spray hits the walls before it reaches you properly. Go too small in a generous space and the whole thing looks a little lost.
As a rough guide, a shower head between 200mm and 250mm suits most standard enclosures comfortably.
Anything from 300mm upward starts to feel genuinely luxurious but needs the space to match, both in terms of the enclosure width and the ceiling height above you.
The spray pattern matters here too. A wider head with a full, even coverage feels very different from a smaller head with a concentrated jet, even at the same water pressure.
Knowing which experience you are looking for will shape not just the size shower head that you choose, but also how and where it is fitted.
Ceiling vs wall mount: installation height
Where the shower head sits changes how the whole shower feels to use. For a wall-mounted fixed shower head, the position of the arm is the detail that makes or breaks the daily experience.
Too low and the spray just isn’t in the right place. Too high and the pressure drops before it reaches you.
Ceiling-mounted shower heads need a bit more planning. Your ceiling height determines whether a flush fitting works for the space, or whether a drop arm is needed to bring the shower head down to where it needs to be.
For both options, it's worth measuring carefully before you press the order button.
Choosing a style and finish
A shower head is a fixture that earns its place visually as much as practically. It’s in your eyeline every morning and compliments everything else you’ve chosen for the room.
And with the range available now, there’s genuinely something for every bathroom, whether you want a shower head that sits quietly in the background or one that makes a bold statement.
Round or square?
Round shower heads tend to suit softer, more traditional bathrooms sitting naturally alongside curved fittings and warmer finishes.
Square and rectangular shower heads feel more at home in contemporary spaces where clean lines already set the tone.
The shape of the shower head you choose is often one of the more personal decisions in the process, and usually the most instinctive one.
Size plays into the experience too, and not just in terms of how it looks on the wall. A smaller shower head concentrates the nozzles more tightly, which creates a focused, invigorating spray.
A larger shower head spaces them further apart, spreading the water across a wider area for a more immersive, all-over feel. But an immersive feel doesn’t have to mean low power.
With the right water pressure behind it, larger fixed shower heads can feel every bit as powerful as a smaller one. They are just spread across a much wider area and cover a lot more of you in the process.
Most fixed shower heads have a single spray pattern, but some offer multiple settings that let you switch between a gentle flow and something with a bit more intensity.
Which finish lasts?
Your shower head has two layers to consider. What it's made from underneath, and what you see and touch on the outside. Both affect how well it holds up over time.
The material underneath is where durability starts. ABS plastic is a lightweight synthetic material common across many bathroom products. Brass and stainless steel are heavier and more corrosion-resistant, and that's reflected in the price point as you move up the range.
The finish is what you see every day, and it's where the personality of a shower head really comes through. Chrome is the most common choice and the most low-maintenance, working in almost any bathroom and holding up well over time.
It does show water spots and limescale more visibly than other options, which is worth knowing if you're in a hard water area.
Matt black has become a genuine design statement over the last few years. It’s a natural fit for contemporary bathrooms, and against dark grout and darker tiles it really comes into its own.
Water spotting shows up more readily on darker finishes, so it does need a little more attention to stay looking its best. But that’s a minor trade off for a statement look you’ll enjoy every single day.
Brushed brass sits at the warmer end of the market, and in the right bathroom it brings a richness and warmth that's hard to replicate with anything else. Like all finishes, it's best cleaned gently with warm soapy water rather than anything abrasive.
With the style and finish in the bag, there’s one more thing worth checking before you commit. And it’s the thing that turns a shower head you love the look of into one you actually love using.
Shower Heads and water pressure: what you need to know
Water pressure does more to determine how a shower head performs than almost anything else. The same shower head can feel powerful at the right water pressure, or patchy and underwhelming at the wrong one.
Water pressure in the UK is measured in bar and most homes sit somewhere between 1 and 3 bar.
Checking your water pressure before you buy
Most shower heads have a minimum water pressure listed in their product specifications. This will give you an indication of what you need to get the best out of that shower head.
The jug test is a quick and easy place to start.
-
Place a one litre measuring jug under your shower
-
Turn the shower on full and run it for 6 seconds and then turn it off
-
Multiply the amount of water in the jug by ten
This gives you your flow rate in litres per minute. It’s not a bar reading but a useful first indicator of whether your pressure is likely to be an issue.
Below 10 litres per minute is generally considered low pressure and worth factoring in before choosing a larger shower head.
Rainfall shower heads for example, with their wider diameter and larger spray area, generally perform best with good water pressure behind them. At lower pressure, you risk the shower never quite delivering and the experience loses most of what makes them appealing in the first place.
For an exact bar reading, a pressure gauge is the way to go. You can find them online and at most DIY or hardware shops. They attach directly to a tap and take seconds to use.
This will give you a precise figure which you can check against the product specification on the shower head you want before you commit to the order.
Fixed shower heads and electric showers
Electric showers heat water on demand as it passes through the unit, which means they rely on a consistent flow of water to work properly. Unlike a mains-fed system, they operate at a fixed, often lower flow rate.
Fitting a large fixed shower head to an electric shower can cause problems. If the shower head needs more flow than the unit can deliver, the water won’t heat up properly and your shower will become a lukewarm experience and not the relaxing one you were hoping for. In some cases it can affect the unit working at all.
If you have an electric shower, look for shower heads with a low minimum pressure rating or designed for low pressure systems to make sure you get the best match.
How to change a fixed shower head
Swapping a like-for-like fixed shower head is a job most people can do themselves in under half an hour.
Here’s what you need and how to do it:
- An adjustable spanner or pair of grips
- PTFE tape
- A soft cloth
- A spare washer, just in case
The steps:
-
Turn the shower off at the valve
-
Place a cloth over the drain to catch anything small that drops
-
Unscrew the old shower head anti-clockwise by hand. Use the spanner if it’s a bit stuck
-
Check the washer inside the fitting, and use the spare one if it looks worn
-
Clean the threads on the shower arm and remove any old tape
-
Wrap your new PTFE tape around the threads two or three times. This is to create a firm watertight seal when you attach your new shower head
-
Screw on the new shower head by hand. Use the cloth around the shower head to protect the finish while you are working. You can secure the last turn with the spanner to ensure a firm seal, but don’t screw in too tight!
-
Turn the shower back on and check for any leaks. Got some drips? A bit more PTFE tape on those threads should fix it.
Do you need a plumber?
For a straight swap in the same position and the same type of fitting, you almost certainly don't need a plumber. The steps above cover everything you need.
Where a plumber earns their place is when the job goes beyond a like-for-like change.
Moving the position of the wall arm, running new pipework, or installing a ceiling-mounted shower head where there wasn't one before, all involve work behind the wall that's worth leaving to someone who knows what they're doing.
If you're adding a shower handset alongside your fixed shower head, a diverter valve is worth knowing about. It fits between the wall arm and the shower head and lets you switch between the two without any additional pipework. It's a genuinely useful addition and something you should have no problems fitting yourself.
Combination setups are increasingly popular. This is where a fixed overhead shower head is paired with a shower handset on a separate rail. They are great for family bathrooms where different people want different things from the same shower.
It’s worth involving a plumber early on these setups. Getting the pipework right from the start can save a lot of disruption further down the line.
