Low, Yet Powerful
In spaces with limited installation height, standard elements simply don’t fit. That’s where the DUPLO WC 387 shines. At only 83 cm tall, it allows installation under windows, shelves, or sloped attic ceilings. Its compact design also makes it an ideal choice for kindergartens, schools, and other public restrooms where space is often limited.
Despite its low profile, this cistern makes no compromises – it offers all the key features you’d expect from a premium concealed system.
Why Choose the DUPLO WC 387?
- Flexible flushing plate positioning
With the DUPLO WC 387, you can choose between top or front flushing activation, meaning the position of the flushing plate can be adapted to your space and design preferences.
However, we recommend installing the flushing plate on the top of the cistern. With front mounting, the raised toilet seat can occasionally rest against or bump into the plate. While this is neither a malfunction nor a functional problem, it’s not the most practical setup – so top mounting is often the more sensible solution. - Compatible with various flushing plates
The model is suitable for mechanical or pneumatic flushing plates from the Gaios and Thira series, which come in various designs and materials – ensuring seamless harmony with your bathroom’s style.
- Outstanding performance and quiet operation
With integrated dual flush (3/6 liters), it supports water-efficient use, while the hydraulic valve operates quietly – a great choice for peaceful homes or noise-sensitive public areas.
- Compact but fully equipped
Everything you need for installation comes included in the package. Bonus: the system is compatible with cleaning tablets, ensuring added hygiene and freshness.
