I'm working on remodeling our bathroom, specifically a 4x4 ft toilet room that I soundproofed to avoid any awkward moments between my wife and me. I used a bunch of soundproofing techniques including staggered studs, Rockwool insulation, mass-loaded vinyl, 5/8" drywall, acoustic caulk, and a sound-dampening door called IsoDoor SD. While the door knob isn't installed yet, it's already looking promising in terms of soundproofing. My main worry is that since the room is tightly sealed, will the exhaust fan work properly once it's installed? Without any airflow coming in, will I be able to breathe in there? Do I need to add an air intake?

Honestly, if the room is airtight, your fan won't perform well. Think about installing a fresh air intake to keep the airflow right. It can help even out the pressure without letting too much noise through. You can also look into an energy recovery ventilator (ERV) if you want to get fancy, but that could involve running additional ducts outside, which is a bigger project.
That’s smart advice! Ideally, you want to manage both air exhaust and intake properly without letting noise run amok.
If your door is sealed with weatherstripping around all edges, your exhaust fan may struggle because there's no replacement air for it to pull in. You can breathe, but airflow will be pretty stagnant until you open the door. Sometimes, after using the toilet, unpleasant odors stick around due to the fan's inefficiency. If you want to avoid venting through the door, consider adding a small vent pipe from a nearby closet to help with air intake while minimizing sound leakage.
That's a solid point about needing an intake. Sounds like you chose some high-quality materials for the door though!
Yeah, without clearance at the bottom of the door, the fan isn't going to work effectively at all.
You know, I wonder how far you're willing to go to create a perfect escape from toilet noises. If it’s really that necessary, you might want a little noise machine outside instead of battling all this sealant. It could serve as a simpler solution without needing an intake, but I get the aesthetics need to be right too!
Haha, I think a white noise machine might not make it easier to cover all sounds! Easier said than done when your bedroom's nearby.
Good call on the ERV! Just remember to keep fresh air intakes away from the exhaust to avoid counteracting each other.
