I am remodeling my bathroom and want to remove the wall with the shower valve. It is about 3 feet away from the exterior wall on the left that the trusses are sitting. Is this serving any purpose or was it just to encase the shower stall? I thought i could remove it until i saw the extra bracing on the end of the wall. being that it is so close and short i assumed it was just for the shower. Now im not sure. Its about 3’ long.
