  • Hello, and welcome to Home Improvement. I'm no pro, but I'm guessing you'll have venting problems there. And, you should probably take our tour so you'll know how best to participate here. Nov 7 '19 at 15:02

Found this at https://inspectapedia.com/ Which references Maryland plumbing codes. You should check your local code for what's appropriate in your situation.

The second table, which shows trap-vent distances says that for a 2" trap (shower) the maximum distance to the vent is 5 feet. You're way over. It also specifies a minimum vent size of 3"
