GRAND + CORAL set automation and comfort in one set
The GRAND smart toilet features a lid that opens as you approach, a steel nozzle, electrolysed-water technology and deodorisation.The CORAL frame simplifies the cleansing-water connection and enables automatic and remote-controlled flushing.
Front and rear wash
Warm water and adjustable water flow.
Warm air drying
Adjustable drying temperature.
Heated seat
Set the temperature to your preference.
Three elements in one set
GRAND I7-5
An approach-activated lid, a steel nozzle, electrolysed-water technology and deodorisation.
CORAL
Flushing cistern and a factory-routed hose for the cleansing system.
CORAL BLACK
A conventional push button. Manual flushing also works without electricity.
Less work routing the water supply
The frame has factory-separated supplies for flushing and cleansing water. An additional hose runs through a dedicated channel, so the installer does not need to add a tee fitting or route a separate pipe behind the enclosure to the shower toilet.
Automatic and remote-controlled flushing
The dedicated CORAL concealed cistern system enables automatic flushing about 5 seconds after you stand up, even without using the cleansing functions. You can also flush with the MAJOR&MAKER button on the remote. Starting drying also triggers a flush; when this happens, it is not repeated when you stand up.
Quiet operation and durable components
The flushing system is designed for discreet, reliable performance. A sturdy frame provides stability, while high-quality internal components support the long service life of the concealed installation.
Easy servicing and spare parts
Removing the flush plate gives you access to key components without disturbing the bathroom finishes. We provide long-term access to spare parts, so individual components can be replaced when needed instead of the entire frame.
The wall button works without electricity. The toilet’s cleansing and automatic functions require power.
Daily hygiene with added convenience.
Lid automation, a steel nozzle and deodorisation form a practical set of features. GRAND is designed for people who want greater convenience in everyday use.
A lid that opens as you approach
The lid opens as you approach within about 1 metre. The sensor is on the upper body; raise the seat with the remote or by hand.
Stainless-steel nozzle
A durable, easy-care surface, with automatic nozzle rinsing before and after cleansing.
Electrolysed-water technology
Water electrolysis supports cleaning of the cleansing system components, complementing routine product care.
Deodorisation
A built-in activated-carbon system helps reduce unpleasant odours while the toilet is in use.
Essential functions on the side
Three buttons: rear cleansing, front cleansing and STOP. Use the remote for full adjustment, additional modes and seat and lid controls.

Plan the set installation.
The CORAL frame and flush plate are included. Plan the frame’s water supply, waste connection and toilet power supply before finishing the wall.
CORAL frame included
Toilet fixing centres: 180 mm. The drawing below shows frame dimensions and mounting points.
Cleansing-water supply
Use the additional hose factory-routed through the frame. Connect it to the cleansing system as specified in the manual.
220 V power supply
Prepare an electrical cable with proper earthing, following the installation manual.
CORAL automatic-flush connection
Connect the factory-prepared connectors on the toilet and the controller inside the frame. The controller operates the flushing mechanism pneumatically. A working connection and power are required for automatic flushing; manual use of the wall button is independent.
How does flushing work?
The set flushes about 5 seconds after you stand up, even if no cleansing function was used. You can also flush with the MAJOR&MAKER button on the remote.
Starting drying triggers a flush. If the toilet has already flushed during drying, it does not flush again when you stand up.
The wall button operates mechanically, even without electricity. Automatic and remote-controlled flushing require power and a connection to the CORAL controller.
Preparing the connections
The installation manual shows the toilet’s water, waste and power connections. The frame drawing is included in the dimensions section.
