The series host quipped that he is not sure whether the US Olympic swimmer would make a great addition to the dating show, given that he has a penchant for peeing in pools.
"Here's the problem: you can't pee in the hot tub," Harrison told Access Hollywood.
"Apparently he told [Ryan] Seacrest he pees in the pool every time he gets in," he continued. "You can't pee in the hot tub - that's not hot! That's not sexy."
However, Harrison went on to say that Lochte's alleged proclivity for one-night stands would make him a good contender for the next Bachelor.
"He'd be a great bachelor," he said. "Well, didn't he tell his mum, or his mum said he does a lot of one-night stands or something?
"I'll make an honest man out of him!" Harrison added.
The Bachelor and its sister shows The Bachelorette and Bachelor Pad air on ABC.
