Invisible ventilation instead of visible covering
The Royal Flush flush-mounted fan 125 mm blends flush into the tile surface and ensures functional ventilation for bathrooms, WCs, and utility rooms without a visible ventilation grille interrupting the tile pattern. Instead of a classic plastic grille, only a subtle, narrow joint remains visible in the tiled wall after installation – air flows discreetly over the tile edge. This maintains a continuous tile look, a calm and harmonious overall appearance, and gives the bathroom a clean, high-end feel – fully in line with Karl Dahm's Royal Flush series for invisible, tileable sanitary solutions.
Unlike the 100 mm version, the Royal Flush flush-mounted fan 125 mm comes with two cutting templates: the first is used for the precise outer tile cutout for installation, while the second allows you to cut an additional tile ring for the fan's inner frame. This ensures that even when the center piece is removed – for instance, for cleaning – no visible black plastic frame remains, only tile. The result is a consistently invisible solution, even when open.
The fan is installed precisely beneath the tile and cut out accurately and repeatedly using the included cutting templates. The robust center piece can be removed without tools for maintenance and cleaning and is held securely via neodymium magnets – for permanently reliable ventilation without compromising on design.

Bathroom, WC, utility room, and technical room – wherever discreet, invisible ventilation combined with a high-quality, flush tile pattern is desired. Thanks to the second inner frame, it is particularly recommended for visible areas where no plastic edge should catch the eye, even with the lid removed.
The ventilation grille itself disappears completely under the tile, allowing air to flow discreetly over the tile edge and preserving the seamless tile appearance.
First, the outer tile cutout for installation is prepared using the first template, and fixation is subsequently achieved using the supplied neodymium magnets and screws.
This tile ring is inserted into the fan's inner frame so that only tile – and no plastic – is visible there as well.
Unlike simple ventilation solutions, no visible black plastic edge is revealed when opening the center piece – the appearance remains consistently high-end.
It serves as an invisible mounting system behind which a 125 mm fan is fitted precisely into the flush-mounted assembly.
This allows quick and easy cleaning and maintenance at any time, without damaging tiles or requiring tools – and without revealing a visible plastic frame.
The set is completed with the full fastening material – 4 neodymium magnets as well as 4 screws and nuts.
The series combines tileable, design-oriented sanitary solutions such as access hatches and flush plates that integrate invisibly into the tile surface.
