Cheers ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great product *by on Reviewed in the United Kingdom 27 July 2026* Easy to install, sturdy and all parts are there, flushes perfectly ### ⭐⭐⭐⭐⭐ Love Grohe products *by on Reviewed in the United Kingdom 8 April 2021* I've had two of these installed now, the installer was surprised when I said how much I'd paid on Amazon too. These just seem to have an engineered quality about them, I've also bought Grohe taps and shower systems.The wall mounting of the pan is hygienic and looks better, especially in a small room, yet feels more solid than a floor mounted pan.Look for the kit that comes with everything including the flush plate, as these are the best value IMHO. The flush is powerful and always cleans the bowl first time.I coupled this with a Rimless RAK Resort Compact D Shape Wall Hung Toilet WC Soft Close Seat 520, which is well made and incredible value. ### ⭐⭐⭐⭐⭐ Nice *by on Reviewed in the United Kingdom 1 March 2026* Great ## Frequently Bought Together - GROHE 38772001 Rapid Sl 3-in-1 Set for Wall-Hung Toilet (Wall Brackets and Skate Cosmopolitan Chrome Flush Plate) - GROHE 28143000 RelexaFlex 59" Metal Longlife Shower Hose, Starlight Chrome - GROHE 35601000 Rapido Smartbox Universal Rough-In Box, Starlight Chrome --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sg/products/48844151-grohe-rapid-sl-3-in-1-wall-hung-toilet-concealed](https://www.desertcart.sg/products/48844151-grohe-rapid-sl-3-in-1-wall-hung-toilet-concealed) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-11-10*
