New White Bathroom Floating Toilet Wall Mounted With Grohe Flush Button & Parts

  
Was bought as part of a renovation project but didn't get used, however it has been keep in storage in a box. Unsure what brand the porcelain toilet is, it comes with parts but it's missing the metal wall piece that it needs to be mounted to. The toilet flush button brand is grohe, it has some scratches on it from being in storage, it's difficult to photograph but please see images.
