Grohe 82mm wallhung cistern ,boxing in?

[Artful]

We are refitting our cloakroom and have installed a Grohe 82cm frame under the window and a wall hung toilet (the latter temporarily ) Does anyone have a template for the front concealing panel to fit the tiles to ? We expected there to be one in the box. There's always a chance for error if measuring for the pipe work oneself. We are fitting the flush plate in the shelf that forms the top of the boxing in. For either side we have purchased some shallow IKEA children's bedroom fittings that take small baskets but used vertically with the runners removed they are perfect in depth and height. We'd also appreciate any other advice or tips for this job .Thankyou
