Hello all...I am remodeling the master bathroom and am building a nice custom shower. Due to the way the shower is laid out now I am removing a wall in between the shower and the jacuzzi tub and then switching my plumbing over to the adjacent wall. When I removed the existing shower I noticed (attached photo) a HVAC riser running through the wall dead center on where I need to mount my shower body. I am stumped as ti figuring out if there is any way I can shift this riser over even 4 inches to get some space in the bay for my shower valve. If there is anyway to move it to the right so I can hug the stud I think it would be close enough for me. Any recommendations would be great. Thank you in advance.
