Victoria Plum Wall Mounted Toilet on Grohe Cistern??

[M0mmy]

Hello,

As per the advice of a very helpful forum member I have bought Grohe Rapid Cistern and frame (versus the unknown brands) however now I am trying to buy the pans i am really worried they wont fit. Eg the pan below:

Is being recommended to be used with their own cistern? I really didn't want to use these types and have already purchased and awaiting delivery of 5 grohe rapid cisterns? If anyone has any idea I would appreciate it. thanks
