With bathrooms, sometimes it's what's behind the scenes that counts – like this smart Grohe Concealed Toilet Cistern. This durable design features Grohe EcoJoy technology, helping reduce your consumption while providing the most effective flow. The concealed cistern is also insulated to prevent condensation, reducing the need for maintenance. As standard, the dual flush cistern provides a six or three litre option, but this can be adjusted to use even less water if desired.
