Origins

Seemingly from fluō (“to flow”) + -trum. The -s- has been explained either as an analogically transferred consonant from words that originally had a root-final dental (e.g. rāstrum, rōstrum), or as a remnant of an original s-stem neuter noun ending in *-os (with a phonetic development like *flov-os-tra > *floustra > flūstra; compare *re-vorsos > *rovorsos > *roursus > rūrsus and frūstrā); compare also mōnstrum, lustrum and lūstrum.
