The programme, which had an average of 5.4m viewers across its run, was the most watched entertainment show on UTV in the past five years.
It concluded in a live final on Saturday with Eddie 'The Eagle' Edwards crowned winner.
"Splash! has proved itself by building a big, enthusiastic, primetime family audience," said ITV's Director of Entertainment and Comedy Elaine Bedell.
"We've seen some quite incredible bravery from our celebrities this series, and the scale of the dives they were achieving is in no small part down to their mentor, and the star of our show, Tom Daley. We're looking forward to even more Saturday night spectacle, and sparkle, with the second series."
Olympic diver and host Tom Daley said it was a "dream come true" to be involved.
"I am over the moon to hear Splash! will run for a second season," he said. "It's a dream come true for me to be involved in an entertainment show which has been so successful and also fits so well around my training schedule.
"Splash! has put diving on primetime TV and diving clubs all across the country have kept telling me that they now have waiting lists, following the popularity of the show. That in itself is an incredible achievement and I'm very excited to be part of it."
