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. ## Features - Suitable to be used as a dual or single flush - 0.82 m installation height - Front actuation - Connection from left / right or back - 415 x 140 x 360 mm - For use with horizontal plates - Easy installation system with straightforward instructions - Minimum recommended pressure 0.2 bar - This product comes with a 5 Year manufacturers warranty ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00505EFFG | | Best Sellers Rank | 166,917 in DIY & Tools ( See Top 100 in DIY & Tools ) 292 in Toilet Tanks | | Brand | GROHE | | Colour | Silver | | Country of Origin | China | | Customer Reviews | 4.7 out of 5 stars 87 Reviews | | Global Trade Identification Number | 04005176275203 | | Included Components | GROHE 38422000 - Concetto Pieza de Inodoro (tamaño: 0.82m) | | Installation method | Wall Mounted | | Installation type | Wall Mounted | | Item Dimensions D x W x H | 41.5W centimetres | | Item Type Name | GROHE 38422000 - Concetto Pieza de Inodoro (tamaño: 0.82m) | | Item Weight | 1 Kilograms | | Item weight | 1 Kilograms | | Manufacturer | Grohe | | Material | Material: Metall | | Model Number | 38422000 | | Part Number | 38422000 | | Product dimensions | 41.5W centimetres | | Seat Material Type | Plastic | | Shape | Round | ## Product Details - **Brand:** GROHE - **Colour:** Silver - **Item weight:** 1 Kilograms - **Material:** Material: Metall - **Product dimensions:** 41.5W centimetres ## Images ![GROHE 38422000 WC Concealed Cistern 0.82 m - Image 1](https://m.media-amazon.com/images/I/41TRNwbqrLL.jpg) ![GROHE 38422000 WC Concealed Cistern 0.82 m - Image 2](https://m.media-amazon.com/images/I/51QriYznOeL.jpg) ![GROHE 38422000 WC Concealed Cistern 0.82 m - Image 3](https://m.media-amazon.com/images/I/51RuuPUUY+L.jpg) ![GROHE 38422000 WC Concealed Cistern 0.82 m - Image 4](https://m.media-amazon.com/images/I/51UzuB1tYAL.jpg) ![GROHE 38422000 WC Concealed Cistern 0.82 m - Image 5](https://m.media-amazon.com/images/I/61uC4zfrjDL.jpg) ## Questions & Answers **Q: My window is 900mm my toilet is 400mm high .will this Cistern fit under my window.?.
