Back-to-wall toilet: fit with furniture unit?

[NumptyMum]

I'm getting very confused: we have builders who are going to be fitting our bathroom - which will be from scratch, as rooms in the house are shifting round due to exetension - so I'm buying in the goods. My DH got a 'back to wall' toilet pan off gumtree (ROCA laura pan) cheaply, so we're planning on using this.

So... can we fit this with a 'back to wall' cabinet? does this need to be of a certain height or depth for us to fit the correct cistern? And what cistern would we need to fit?

ROCA only seem to do the proper 'built into wall' cistern and because it's built into a wall, it seems to be quite high up/large to me! I don't want a fully built in cistern as I can imagine trouble if there are leaks... but I'm also not getting my head around what kind of cistern to fit into a unit, and how to check whether the flush for this should be on top or at the front (and if indeed it will flush well, given sometimes those push-button things aren't great). I think I remember someone on here saying that Grohe were good for cisterns...

At present I'm either looking at basic Hudson Reed cabinet (either 225mm or 355mm for depth, and they come in either 500mm or 600mm for width - so again, no idea how cisterns fit with these) or otherwise, Tavistock Compass 570mm x 233mm which says it's compatible with 'both Tavistock Vortex and Apex cisterns'...

If anyone can help me understand how all this works I'd be really grateful! ...

If you buy a cabinet to conceal the cistern then your plumber will just fit a plastic cistern to the wall which is then covered by the unit and connected to the toilet pan. Most cistern cover units have magnetic covers which are pretty easy to remove to access the cistern should you need to. It's usually the front which can be removed. They have magnetic catches.

Thanks fudge. DH has just said that we could also consider builders making a party wall/shelf thing, using a cistern that has its own hanging frame... so I'm now going to check out that option....

Pigletjohn, if you're around - I'm pretty sure I've seen you say to avoid the push-button thingys, is it possible to get these types of cisterns with a good flush, or even a handle...??

I think most back to wall toilets actually rest on the floor via a concealed frame that is fixed to the floor and wall, so the BTWpan should come with a fairly heavy duty bit of frame/fixing, and the cistern can be fitted within that or in a unit.
