Compatibility
Fits every shower faucet.
Showrz screws onto the standard 1/2" outlet used by shower faucets across Europe. Thermostatic, single-lever mixer, two-handle, tub/shower or built-in: it works.

Thermostatic mixer
The most common in newer showers.

Single-lever mixer
One lever, hot and cold.

Two-handle faucet
A rental classic.

Bath-shower mixer
Right above the tub.

Built-in
On the wall outlet.

The 5-second test
Does your hose unscrew by hand? Then it's compatible.
Look under your faucet: if your current hose unscrews, Showrz will fit at your place. Not sure? Send us a photo of your faucet and we'll get back to you quickly.
How to check
The 5-second test
Look under your faucet. See a nut holding your current hose? Unscrew it by hand. If it comes off, it's a standard 1/2" outlet (15x21): the norm in France and across Europe for decades. Showrz screws on in exactly the same spot.
The filter screws between your faucet and the hose. The shower head screws onto the end of the hose. No tools, no washers to buy: everything's in the box.

What about the wall?
The rail just sticks on.
The rail never touches the plumbing: it sticks to the wall with heavy-duty adhesive mounts. It holds on tiles, ceramic, glass and smooth stone. It doesn't hold on paint, wallpaper or deeply recessed grout lines.
- Tiles and ceramic: yes
- Glass and smooth stone: yes
- Paint and wallpaper: no
Questions
Your compatibility questions
My faucet is built into the wall. Will it work?
Yes. Built-in showers have a small wall outlet (a chrome elbow) where the hose screws on. The filter screws onto it, just like on an exposed faucet.
I have a bathtub with a bath-shower mixer.
It fits: the filter screws under the hose outlet, and the rail sticks on above the tub.
I have a shower column with an overhead shower.
The Showrz shower head screws onto your column's hose. The filter screws onto the hose inlet.
My hose won't unscrew.
It may be stuck with limescale: a little hot white vinegar and a towel for grip usually does the trick. If not, send us a photo and we'll figure it out with you.
