The 34-year-old singer, actress and former "Dancing with the Stars" contestant shared photos from the ceremony Sunday on Instagram while reflecting on the ups and downs of her year in 2017.
"2017........you broke my heart, you broke me down, you made me question everything, but damn did you make me strong," Kramer captioned the slideshow.
"You taught me patience, you taught me family was everything. You made me believe not only in myself but the power of forgiveness. You turned me into the women I always wanted to be."
"I have NO clue what 2018 has in store for me but I've never been more ready to live day by day and enjoy each day as it comes at me," she added.
"Here's to always believing in love and fighting for it.... (Pics from Hawaii Dec 2nd...vow renewal.. photos by @rodrigomoraesphotography)....2018 I'm ready for you!"
Kramer and Caussin, who share 23-month-old daughter Jolie Rae, reconciled in 2017 after separating the year prior.
The singer miscarried their unborn second child just a week after their vow renewal ceremony.

"When I first found out I was pregnant I wanted to shout it from the rooftop but I know for reasons like this we have to wait."
"For the women out there who have miscarried in the past and need support and a place to grieve their little one lost or to those in the thick of it like me who are currently grieving and in pain, let us all be there for each other," the star said.
"You don't need to feel alone."
Kramer is known for playing Alex Dupre on The WB/CW series "One Tree Hill." She last released the album Thirty One in October 2015.
