Changing width of bars created with catplot or barplot

I'm trying to create bar chart using seaborn.factorplot. My code looks like this:

import seaborn as sns
import matplotlib.pyplot as plt 
 
df = pd.read_csv('data.csv')
 
fg = sns.factorplot(x='vesselID', y='dur_min', hue='route', size=6, aspect=2, kind='bar', data=df)

my data.csv looks like this

,route,vesselID,dur_min
0,ANA-SJ,13,39.357894736842105
1,ANA-SJ,20,24.747663551401867

Now my question is how to change the width of the bar and I'm not able to achieve this by changing size and aspect.

In my case, I didn't have to define a custom function to change the width as suggested above (which btw didn't work for me as all the bars were unaligned). I simply added the attribute dodge=False to the argument of the seaborn plotting function and this made the trick! e.g.

sns.countplot(x='x', hue='y', data=data, dodge=False);

My bar plot looks now like this:
