Plumbing/Hydronic/HVAC estimator here. This is the answer. Not to mention we don't know the full application of the setup. Wall mounted or floor mounted toilets? The image shows tank floor mounts. So your 4" main line is under floor. Not to mention the number of fixtures units in this setup is so high this is probably a restroom with a 8" sanitary main line.

And that is just the sanitary. The domestic water layout is totally screwed. You could still run in-wall carrier group distribution. But you would need to run so many size transitions to fit out the full wall.

Honestly, I would say this doubles the labor. Odd layouts like this always catch people off guard on the true cost impacts. There is no consistency of the layout to gain efficiencies and the layout eliminates the ability to combine the vent lines in an optimal way through a carrier group. Might as well stove pipe the install. Not to mention what this does for your shock arrestor layout and wall cleanouts.

Yes!!! I feel seen. I tried to clarify a lot of my normal "depends on design" criteria but it went on for too long. As someone who is dipping their toes in pipefitting/sheetmetal, If you're in colorado let me know. I owe you a beer 🍻

Haha, you should troll the plumbing reddit pages. They make you cringe at the residential installers this industry has birthed from the lack of passionate trades people.

Yeah, Denver CO. Been in the industry since 2012. Lived through the chaos of 2016-2019 when CO didn't have enough licensed trades workers that the union hall bench was empty and merit shops were pulling in people from the surrounding states just to put bodies on jobsites. You learn alot during those times.

I couldn't imagine how crazy it must have been during Denvers boom. Ya know what? I'm a man of my word. Sent you a message - I estimate with one of the combined scope shops in westminster so tell me a time/place and I'll estimate your tab 🍻
