Grohe Concealed Cistern - Dual Flush - 38422000

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 Grohe 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. It comes with fixing brackets for simple installation. Why not add the Grohe Arena Cosmopolitan actuation plate to complete your set up?

How We Gather Reviews

Grohe cistern

Excellent cistern complement for choosing this from the fitter. However be aware when ordering to fit into a 500mm wc unit, the unit is too tight for it and the fitter will need to cut bits of the inside of unit to get it in! This was very fiddly and time consuming. Bless our determined fitter. Looks stunning after a long days job! Again after weeks of emails/online chats/phone calls advice on compatibility was a load of rubbish!

Basic Design Flaw

Love the brand, love the action, love the quality. However, unless you purchase the additional flush extension pipe, you'll find that the button plate sits behind the toilet seat meaning you can't flush the toilet without putting the seat down. "No bad thing" I hear women rejoice around the world... However, because you have to put the seat down to flush, you have no way of knowing whether everything has flushed without then raising the seat to check.... Extension pipe shouldn't be an add-on.

Fantastic Flusher

Every morning I am reminded and marvel at the technical excellence and engineering imbued within this product. Does the designer equally take time to reflect? I will never truly know, but it gives me great comfort to imagine they do.

7 Questions

Cistern overfills and keeps running into toilet bowl

Asked by Bob

ANSWER

Technical Team. replied on 8th October 2021

Hi, The problem will be that the internal float valve which allows the water in and shuts off when at the correct level, so it is that valve that will need adjusting. Thanks. Technical Team.

Can the height of this cistern be adjusted? I want to install a concealed cistern, but would like to have the actuator button above the height of the toilet seat (when the seat is up). Is there any way to extend the length of the pipe which goes into the toilet basin?

Hello, Thank you for your question. Unfortunately not this one the flush button location cannot be moved. We would suggest a pneumatic or cable-operated cistern so the flush button can be located further away. Kind Regards.

Can you use other brand flush plates?
