    On installing my toilet, I've found that I have small gaps between the bottom of the toilet and the floor tiles in places - slight bowing in the tiles is the likely culprit. By probing with packing pieces I know that these gaps are no more than 1-2mm, but I'd rather have the load of the toilet spread out fully.

    I've wondered about removing the toilet and putting a bed of plumbersmait around underneath, but a) the toilet was a pig to fit so I'd rather not uninstall and b) I'm not certain the mait would actually carry any load.

    I thought about squirting one of the more fluid gap-filling builders adhesives around underneath, but this doesn't seem wise in case I need to remove the toilet in future... broken pan and broken tiles!

    Is there anything hard-setting, but not too adhesive, that is runny enough to squirt into 1-2mm gaps under a toilet bowl?

    Just use a silicone adhesive, it'll set hard enough to support it but can still be cut with a sharp blade if lifting. Just don't use a lot, just enough to fill the gaps.
