floor running down in toilet

[panny300]

i have fitted a toilet where the back fits flush to the wall,but the floor of the toilet runs down,so the base of the pan is about 12mm off the floor at the front.
amyone come up with a clever idea to support the front?,as it would need a wedge shape to support front to back.plus how to hide it.

How about a wooden wedge and then silicone all around the toilet edge.

Panny - base of pan should sit firmly on the floor! But how to accommodate the obtuse wall to floor angle (this is a common problem in old buildings) ? .... loosen the cistern on the wall and place two 12mm spacers over the fixing screws behind the cistern. Result is a much neater solution and quicker to do. What to use as spacers - 12mm thick battern of timber, or the way we do it is rubber tap washers stacked to get the correct distance
