Silicone caulk will do fine. It's not going to fall through being a
'drop in'. One that is attached from beneath would require physical
attachment with screws and binders.

Yes, there's no way to physically attach it - it's just unglazed china
underneath. I picked up a tube of DAP bathroom caulk/adhesive which
seems like it will seal and help keep it seated.



I would have gone with one of the 100% silicone products. Silicone is used
for assembling fish tanks BTW. But if it's already in with the DAP, leave
it and address if it fails.

If you ever use silicone, even with a brand new tube, open it and put a
glob on scrap. It should skin in 30min. If it hasn't skinned in 45-60
minutes it's no good and will never dry properly if at all. Many have been
burned by not doing this including yours truly.
