Just a bed of silicone! No screws, no packers, just silicone. Has
worked for two toilets on tile floors so I reckon it's good enough.

Really - hadn't considered that. Seems like an easier idea.

So - just to double check (forgive me - not want to do this job twice!) -
just normal regular silicone? Not acrylic, polyurethane, weird silicone or
anything funky?...
