It would be highly unlikely that the apostles would not have been baptized in water when their master and Savior was baptized in water and 1 Peter 2:21 says that Jesus left us an example that we should FOLLOW IN HIS FOOTSTEPS. There is absolutely no evidence for us to suppose the apostles were never baptized in water and much evidence to suggest that they were. (1) Peter preached baptism for the remission of sins Actsc2:38. (2( Jesus their master was baptised in water and Peter said He left us an example that we should follow. (3) 3000 people obeyed Peter’s preaching and were baptized in water. Wouldn’t Peter have been a hypocrite to preach one thing to others, but not practicing it himself? That’s the definition of a hypocrite. And I know SOMEONE would have brought an accusation against Peter for not “practicing what he preached! No, I don’t believe it is reasonable to suggest that the disciples did not follow Jesus in water baptism.
