Review: Brilliant! - I have always loved Grohe products, which led to the purchase of this cistern for our new bathroom. Perhaps foolishly, I read the reviews after purchasing, and was a little dismayed to read that one customer had had problems fitting it into a 500mm unit - exactly the size of ours - so I was expecting the same problem. Imagine my surprise, then, that I encountered no such issues: the alterations I made were two small blocks of 2x1 to fasten the side brackets to. For the money, it is great value and is near silent in operation, and fills quickly: well “chuffed “ with purchase.
Review: Great for the price - Great concealed cistern , instructions were a bit vague but managed to work it out.

**Q: Hi. Supposed to be single or dual flush but only comes with one hose for a single flush and I note it says a solo flushing cistern. Can you explain?**
A: The push plate has two buttons which push different amounts of air through the single pipe which controls the size of flush.

**Q: What is the minimum instalation height including toilet.my window is 900mm high**
A: Depends how high your basin inlet is. It is not adjustable so it’s determined by that
