Yes, in the vast majority of cases: a shower head screws on with a 1/2 inch thread, the French standard 15/21 thread of hoses and water supplies. Most shower heads therefore fit your current shower hose and sit in a wall-mounted shower holder without an adaptor. Three points remain to check: the thread, the weight on the holder and the type of head.
If you are thinking of replacing your current handset, you have probably wondered whether shower heads are standard. The good news is that in most cases, the answer is yes. However, a few technical details deserve your attention to avoid any nasty surprises when fitting.
The thread: an almost universal standard
In Europe and most countries, shower heads are fitted with a standard 1/2 inch thread (about 15 mm internal diameter). This thread is compatible with most shower hoses on the market. Whether you buy a modern model, with adjustable spray or a rain effect, you can generally screw it on directly in place of the old one without an adaptor.
At Robineto, most product pages for our shower heads state a 1/2″ connection, the French standard thread of water supplies. A few models only say "standard connection": if in doubt, read the product page before ordering, and installation then needs no special tool.
Shower head, hose, overhead head, holder: the compatibility table
| Item | Usual connection | What to check |
|---|---|---|
| Handheld shower head or handset | 1/2 inch (15/21) | the thread stated on the product page |
| Shower hose | 1/2 inch | the length, and the flat washer in each nut |
| Fixed shower head | 1/2 inch in general | the connection on the arm or column, especially in a concealed shower |
| Wall holder | no thread, except a holder with a connector | the weight of the handset and the fixing: screwed, suction or adhesive |
Watch out for incompatible kits and older models
If you have a very old installation, or an integrated shower system from a specific manufacturer, the connection may not be standard. In that case, an adaptor may be needed. These cases remain rare but are worth checking if you have any doubt. Check the diameter of your hose or the reference of your current shower column before buying a new shower head.
High-end or designer models built into specific columns can also use proprietary systems. That is why it is recommended to choose parts compatible with standard components, like those in the overhead shower head collection at Robineto.
The wall fixing: another point to check
As well as thread compatibility, remember to check whether the shower head you choose is compatible with your wall holder. Most models are light and sit perfectly in a universal holder. But some heavier models, such as multifunction shower heads or ones with a built-in filter, may need a reinforced holder.
Our wall holders come in screw-fix, suction or adhesive versions. And for a standard shower arm, choose a compatible shower head with a 1/2 inch thread: it screws on without an adaptor.
Handheld shower head or fixed overhead head?
It is also important to tell two types of part apart:
- The handheld shower head, connected to a hose, which you hold in your hand or fix on a wall holder.
- The overhead shower head or "fixed shower head", mounted high up, usually on the ceiling or on a wall arm. It gives a more enveloping experience with a relaxing rain effect.
Overhead shower heads are sometimes fixed permanently, with a specific wall connection. Here again, most use the standard 1/2 inch thread, but in concealed showers it can be useful to check the exact dimensions before ordering. The difference between the two is covered in our article fixed or handheld shower head: what is the difference.
How do you choose a compatible shower head?
Here are a few simple criteria to consider:
- 1/2" thread: this is the usual thread; it lets you screw the shower head directly onto your hose. Check it on the product page.
- Water pressure: some shower heads are designed for low pressure, others for high pressure. Check compatibility with your installation.
- Spray type: massage jets, rain effect, waterfall... some models have several functions, others only one. Choose according to your preferences.
- Water consumption: water-saving shower heads limit the flow; look at the flow rate stated on the product page.
Spray, flow rate, anti-limescale nozzles: all these criteria are compared in our guide to choosing a shower head.
A standard shower head, but varying functions
Even though most shower heads are standard, their features vary enormously. Some include filters to soften the water, others LEDs, or even boosted-pressure functions. It is therefore important not to rely on design alone, but to read the product's technical sheet to know what you are buying.
At Robineto, we offer a varied selection of shower heads compatible with standard installations, with options for every taste and budget.
And at what height should you place it?
Once you have chosen the shower head, you still have to position it: the handset holder is fixed between 1.20 m and 1.50 m, the overhead shower between 2.00 m and 2.20 m. All the reference points are gathered in our article on the height of the shower mixer, shower head and handset.
The questions we are asked most often
Are all shower heads compatible?
Almost all, with a 1/2 inch hose and water supply. The exceptions are columns and integrated showers with a proprietary connection, and some very old installations: an adaptor then solves most cases.
Are shower hoses standard?
Yes for the connection, most often 1/2 inch, like that of our matt black shower hose. The length, however, varies: measure the distance between the mixer and the highest holder before choosing.
What diameter for a shower head?
There are two diameters to tell apart. The connection is 1/2 inch, that is the 15/21 thread. The diameter of the head varies from one model to another, from the handheld shower head to the large rain head, and is stated on the product page.
How do you change a shower head?
Unscrew the old one by hand, or with a spanner protected by a cloth so as not to scratch the chrome. Check that the flat washer is properly in place in the hose nut, then screw on the new shower head by hand, without forcing it. If it is just scaled up, first try cleaning the shower head before replacing it.
