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. ### ⭐⭐⭐⭐⭐ Great for the price *by on Reviewed in the United Kingdom 8 April 2025* Great concealed cistern , instructions were a bit vague but managed to work it out. ### ⭐⭐⭐⭐⭐ Seems to do the job *by on Reviewed in the United Kingdom 8 June 2023* Our bathroom fitter had no problems installing it (alongside a Grohe back to wall toilet). It is very quiet (at least compared with our old toilet). It's early days but really happy ## Frequently Bought Together - GROHE 38422000 WC Concealed Cistern 0.82 m - GROHE 35601000 Rapido Smartbox Universal Rough-In Box, Starlight Chrome - GROHE 28143000 RelexaFlex 59" Metal Longlife Shower Hose, Starlight Chrome --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co/products/50415256-grohe-38422000-wc-concealed-cistern-0-82-m](https://www.desertcart.co/products/50415256-grohe-38422000-wc-concealed-cistern-0-82-m) --- *Product available on Desertcart Colombia* *Store origin: CO* *Last updated: 2026-08-15*
