Nowhere to exhaust

I am doing a shower cubicle grow. There is no exhaust ventilation in the bathroom at all.
My only fresh air supply is coming in from an adjacent toilet window within the bathroom.
If you can imagine the shower cubicle as the grow room which will be as airtight as possible, I will be running ducting>fan from the toilet window into the
shower cubicle and I have nowhere to exhaust the hot air but into the bathroom, which I thought would be ok but that hot airs only escape is passively out the same window the fresh air is coming in. Will this be ok? Or will the hot air that is passively escaping end up being sucked into the grow area again?
Any solutions?

I thought about draining the toilet and exhausting through the toilet, but Im not sure that it will work?

If I will be ok just exhausting into the bathroom, ill do that..but concerned my grow will just be getting recycled hot air coming in as it will be sucked in as its trying to escape?

Any help/advice would be appreciated. Thanks.

either install a stand alone floor ac unit that ducts to the window and use co2 or you'll need to put ducting on the outside of the window too to separate the in and out air flow. an elbow would do just to shoot the hot air upwards so it doesn't get sucked back into the intake.

Using the same window looks like the only way to go. Cutting a hole in your apt wall will not be a good thing.

How about the opposite? That's what I'd do. Exhaust out the window, put some homemade co2 bottles [sugar, yeast in 2 liters] in the cubicle with a fan on low to circulate that with the bathroom air as is.

whats the point of adding co2 if you're sucking the air out of the room? seems like a waist of co2 to me, though, you are only using yeast and sugar. have you checked what the co2 levels reach with that kinda set up? the ppms?

if that was my room, I would remove the window. I would then replace it with a perfect cut out of 1/2 ply and cut 2 port holes in it. 1 for exhaust and the other for fresh air. When you have a sealed room the in will just get pulled as the air is exhausted. There is your proper air exchange. Put nylons over the in ducting.

You could always pull in from the window, and exhaust through the same window. If you could fit both ductings, that's what I would do. You would have to use duct elbows or something to direct the air (like devolv said). You'd also have to use a carbon filter for your exhaust so it wouldn't smell outside. It would look weird but I assume you have a way to deal with that.

err wrong button, I didn't actually like that but I DO like the couple mg of xans I took awhile back making me miss the actual button I wanted to hit :/
So how do those things work? I asked my hydro shop dude how they shut off at night because your plant doesn't need co2 at lights out. I thought about adding a backdraft damper, photocell relay of some kind and a fan that turns off at lights out, he just shurgged :/

most every bathroom (in the states anyway) has an exhaust fan yours doesn't?
