I'm trying to fix down a new WC pan to a wooden floor.

Normally, one would screw straight down (or at a slight angle with
long screws) into the floorboards to hold the thing steady.

However, the design of this one is such that I can only get a screw in
horzintally (ie parallel to the floor) since the holes are in the
sides of the pan.

It came with no special fixing kit and I've managed to get the bidet
fixed by making a wooden bracket but cannot do the same with the WC
pan due to the bend itself.

Is there a kit I can buy or any other tips you have for getting this
damn thing to fix. I'm at my wits end with it.

Natually, I have tried silicon round the base but this is not ideal.

Thanks.
Rob
