Most showerheads come away from the arm by hand. No plumber, and usually no tools.

VANNR ONE
A filtered showerhead for European bathrooms. It replaces the head already on your wall and holds a replaceable cartridge inside.

Current design targets
- Connection Standard 1/2 inch shower arm, pending confirmation
- Installation Tool-free, replaces your existing head
- Cartridge Replaceable core inside the head
- Replacement Approximately quarterly, pending testing
- Flow Pressure-conscious spray design
- Availability Founding waitlist only
Spray quality and flow under normal household pressure. Seal integrity at the shower-arm connection. Cartridge life under a defined test protocol. Filtration performance of the final production configuration, by an independent laboratory.
That it softens water. That it treats any medical or skin condition. That it removes any specific substance — chlorine, calcium, magnesium, heavy metals, bacteria or microplastics — until we have independent evidence for the product you would actually receive.
Designed for the standard 1/2 inch shower-arm thread common across Europe, so it should fit most fixed wall-mounted showers. It is not intended for handheld-only setups with no fixed arm. Specific compatibility guidance follows before launch; we will not describe it as universally compatible.
The head opens so the internal core can be replaced. The housing stays on the arm; only the core is swapped. We are not publishing an internal diagram until we have the manufacturer's cross-section for the production unit — a drawing we invented would be a claim about the product, not an illustration of it.
Hardness and disinfection are different things. Stockholm water is relatively soft but is treated with chloramine; parts of southern Sweden, Denmark, the Netherlands and Germany are considerably harder. The water report asks for your postal area so we can tell you which applies to you rather than guessing.
VANNR ONE is currently in development. Final compatibility, cartridge life and filtration performance will be published after testing of the finished production configuration.
Installation
One minute to install.

Twist VANNR ONE on
Hand-tighten onto the same shower arm. Thread tape is in the box.
03
Replace the core
Open the head and swap the cartridge. The housing stays where it is.
Development
