Hi everyone! We are finally starting our long-awaited bathroom remodel in our home near Portsmouth Village. The plan is to completely change the layout, which involves moving the toilet to the opposite wall and installing a walk-in shower where the old tub used to be. I’m a bit nervous because I’ve heard that moving drain lines in these older houses can be a total nightmare if not done perfectly. I really don't want to DIY this part and end up with leaks behind the new tiling. Does anyone have experience with a local team that is good at layout changes and rough-in work? I’m looking for someone reliable who can work alongside my contractor and ensure everything is up to code. Any recommendations?
