From 2010 to 2021, he was in a relationship with Lauren Graham, his co-star on Parenthood (2010). They first met on the set of Caroline in the City (1995).

For Six Feet Under (2001), he originally auditioned for the part of David, as he was impressed by the political/human rights message that the role had and he wanted to stand up for the character. However, the creator, Alan Ball had found the role of Nate Fisher impossible to cast, and was impressed by Krause and his tangible chemistry with Rachel Griffiths (Brenda Chenowith).

His only child, a son named Roman, was born in 2001.

Generally avoids the offer of roles playing either doctors or lawyers.
