Back To The Wall Toilet Rocking / Not Level

[DazJWood]

I have a Tavistock back to the wall toilet.

This is going on to a marble floor.

The toilet pan fixes down using two L shaped brackets screwed down into the floor and then two screws inserted horizontally either side of the pan.

When I position the toilet where it should go there is a slight rock. In other words it sits level but if I put pressure on the front of the bowl it rocks forward. This is only very slight and probably talking 1 or 2 mm maybe.

I am thinking there are a few options before I fit it down:

1) Insert some plastic shims to level out the pan, trim them off flush then screw the toilet down and silicone. My only concern would be that the whole of the base would not be fully supported as there inevitably would be gaps.

2) Sit the pan down on something, ie, sand & cement, tile adhesive, etc... I figure silicone would not be any good due to the fact that it would move. Then screw it down.

3) Not do anything other than screw it down. The fixings are near the back of the pan so they may hold it down and prevent the pan from moving forward. I'm not convinced on this one.

I would appreciate any advice.

Thanks in advance,

Daz

Push plenty of grout used on the floor tiles under the loo with a grouting squeegee and sponge off as you would to with tiles. Let it harden off before anyone uses the loo.

use some cardboard or lino where the gap is push it in then trim the excess off and then silicone around the base.

2 bits 15mm copper hammered flat inserted as shims and then clear silicone right round.

Like the grout idea as well.

make sure next time that the wall is tiled perpendicular to the floor.lol.

i put four plastic upvc window wedges around the base of the pan (adjust to fit), fix pan and cistern into place, then fill in with silicone.
