Seaborn overlap columns

I would like to obtain an overlay of the columns, change their width and the distance between them. A bit like you could do in Excel. Is there a possibility?

plt.figure(figsize=[19*cm,6*cm], dpi=300)
sns.set_style("white")
g = sns.FacetGrid(g_grav_brick, col= "WALL CODE" )

g.map_dataframe(sns.barplot, x = "SAMPLE POSITION", y = "WATER MASS",
                                  hue= "SAMPLE DATE", palette = "OrRd",
                                  linewidth=1, dodge=(True),
                                  edgecolor="black")

Here is an example of what I would like to achieve:

Here's what I'm getting instead:
