The 49-year-old guided the Lions to their first series victory for 16 years thanks to a 41-16 win over Australia in the third Test on Saturday, but accepts that plenty could change ahead of the next tour in four years.
"There is a lot of water to go under the bridge before 2017," Gatland said.
"You get opportunities in life if you're part of successful environments and teams and winning a couple of Grand Slams with Wales and reaching the semi-final of the World Cup has given me this opportunity.
"I'm grateful for the chance and if it came up again then it's something I might look at."
Gatland is under contract with Wales until 2015.
