Peter also ties water baptism into the "one baptism" that Paul mentions.

1Pe 3:20 who formerly were disobedient, when once the Divine longsuffering waited in the days of Noah, while the ark was being prepared, in which a few, that is, eight souls, were saved through water.
1Pe 3:21 There is also an antitype which now saves us—baptism (not the removal of the filth of the flesh, but the answer of a good conscience toward God), through the resurrection of Jesus Christ, (NKJV)

"eight souls were saved by water. The like figure whereunto even baptism doth also now save us" (KJV)
