We use our 4 person tent.
Our bathroom isn't comfortable and the space between the door and the floor is just too large a gap! Not to mention that we have to put away all soaps, lotions, makeup, perfumes, deodorant, toilet brushes, plungers, EVERYTHING, wipe all surfaces down w/vinegar & water solution, pad the sink & tub with enough towels & fleece so they don't bump their heads or land hard. Oh AND plug up the drains, check the walls for any holes/cracks, take down the shower curtain (not sure what metal the shower curtain rings are made of, nor the towel racks).
Maybe we will glider-proof one of our bathrooms and add toys to make it more pleasing to our babies...but for the time being, the tent seems THE place for our babies.
