How to move toilet tank back 6 inches?

[samcuddy]

Hello everyone
Moved into a 5 year old ‘new build’ property recently and the toilet was leaking from where the tank meets the bowl. Nothing heavy but enough to need repairing. Anyway
Found out that the toilet tank was leaning very far back and fixed to the wall. The only way to stop the leak was to change the gasket and keep the tank level.
However now there is a gap between the tank and the wall about 4 inches or so and it looks out of place.
I used a 2inch rubber close coupling washer by Euroflo when replacing.
What are my options here?
Would a doughnut foam washer make any difference?
Do I need to have the complete toilet moved back to meet the wall?
Or is there any type of gasket I can get that allows me to tilt the toilet tank that far back so it meets the wall?

Thanks for any help!

Any pictures of what you mean ?

This isn’t the photo of my toilet it’s one off google as I am currently out. However this illustrates roughly the distance the toilet is from the wall. It was leant back and secured to the wall at the top of the tank which the lean was causing the leak. Having it level has stopped the leak but it now looks out of place.
Thanks

The tank would normally contact the wall all the way along its back. It shouldn't slope. If it's a couple of inches as in the image and you can't relocate the entire WC (should be easy enough if the waste exits straight through the wall behind the WC), easiest way is make a kind of wooden (painted or plastic coated) box to act as a spacer. Or painted wooden spacer behind the top of the back of the cistern if you only care about the view from the top.

On a newbuild, you'd have hoped not to find this kind of thing!

Unfortunately some new build plumbing is not the best , removal of the hide away cistern and building out of the wall to support the cistern is the way to go two timber battens of the appropriate thickness and a piece of ply would be my choice then replumb it back in and make repairs . Kop
