Product information
Bernstein shower toilet Basic 1104 with Geberit pre-wall element - complete WC set for simple and safe shower toilet installation
By combining shower toilet, pre-wall element and matching connection set, a WC is created as a complete set for modern bathrooms with high demands on hygiene and comfort. The WC set includes the Bernstein Dusch WC Basic 1104, the proven Geberit Duofix pre-wall element, a matching Geberit actuator plate as well as a water connection set. All components are optimally matched to each other and enable safe installation of a wall-mounted shower toilet - both in new builds and in the modernization of bathrooms.
Easy operation and reliable hygiene
The Bernstein Dusch WC Basic 1104 has been developed for particularly simple and reliable use. The most important functions of the wall-mounted WC or shower toilet in the set can be controlled quickly and intuitively via the control knob mounted on the side. The rear and lady shower gently cleans with warm water. Slight forward and backward movements of the shower arm ensure that the cleaning area is optimally reached. Water temperature and shower spray intensity can each be adjusted in five levels and individually customized. The stainless steel shower arm is equipped with an antibacterial nozzle. This cleans itself automatically before and after each use. For thorough cleaning, the nozzle can easily be removed if required. The powerful 180° vortex flushing system, together with the rimless ceramic, ensures particularly effective cleaning of the toilet bowl. An antimicrobial WC seat with soft-close function further increases hygiene. An integrated night light makes orientation in the dark easier.
Geberit Duofix as a stable concealed base for your complete shower toilet set
The Geberit Duofix pre-wall element ensures safe installation. The self-supporting steel construction is powder-coated and designed for long-term use. Height-adjustable, galvanized foot supports ensure precise installation of the wall-mounted WC in the coordinated set. The integrated concealed cistern is insulated against condensation and supports economical water consumption. The flush volume can be adjusted individually and allows immediate re-flushing if required. Tool-free maintenance facilitates later service work.
Actuator plate and connection set included in the complete WC set
The WC set includes a Geberit Sigma actuator plate with dual-flush function. For harmonious coordination with the bathroom design, two color variants are available: glossy white or glossy black. The included water connection set enables professional integration of the shower toilet into the existing installation. This complete shower toilet set combines functional hygiene technology with Geberit’s proven installation quality and offers a practical solution for modern bathrooms, guest WCs or commercial applications.
