Review: Love Grohe products - I've had two of these installed now, the installer was surprised when I said how much I'd paid on desertcart 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.
Review: Great kit - Very easy to install. Works perfectly. Everything good quality. Would get again.

**Q: Can the flush plate be changed? Is it a universal fitting? Thanks**
A: The flush plate can be changed on this but it has to be a Grohe flush plate as it is not universal

**Q: If the void where I want to install this is more than 230mm can I not use it?  I have a soil pipe which is 250mm out from the wall it sits alongside.**
A: You can install wall hunt toilet you just have to Build the fixings on the wall out by putting a piece of timber there and then you need a Bendy sort pipe that should work

**Q: Hi, is there a way to adjust water stream speed or tank height? Thanks**
A: Yes you can adjust the tank height by adjusting the frame which raises or lowers the toilet. You can adjust the volume of the water. Cheers

Very easy to install. Works perfectly. Everything good quality. Would get again.

### ⭐⭐⭐⭐ Quiet but tall cistern
*by M***L on 29 May 2021*

Purchased this and installed it. Note that this model is particularly high! It was higher than I had thought so I had to make a feature of it in front of window. It worked out well and despite the extra high model I am very pleased with the outcome. Its good value and Grohe is top class.
