I gutted my entire bathroom down to the studs and joists. I will replace the tub with a shower. I'm not sure the best way to handle the water pipes. In the picture you can see the water pipes on the outside of the studs, upward at an angle. I will have to move the pipes because of the shower floor. My first idea was to build a wall inside the existing wall for the plumbing, however, I will be adding another joist next to the butchered one. The drain would have to move and would end up where the new joist is located. My second thought was to build a half wall on the side and bring the pipes up. I'm open to any suggestions.
