About 1.5 hours
The tours at the Owens-Thomas House & Slave Quarters are aprroximately 45 minutes. Plus, you can spend time in the orientation gallery, garden and basement on your own before and after the tour.
About that... but there are a lot of different tours. I had a lot of fun on the haunted tour and the day tour. If we had gotten to Savannah earlier, I would have purchased the day tour so I could get off of the bus at different stops. We just purchased a regular tour with the haunted tour.
