Mom and Dad decide to build a secret bathroom after they become sick of waiting in the long bathroom line.
Early in the morning, Rita and Lynn Sr. hurry to the bathroom for urgent reasons. However, the line for the bathroom is incredibly long, and they must wait, no matter how long it takes. Tired of the long waiting time (and refusing to use a bucket Lana uses named Old Sloshie as an alternative), Lynn Sr. recommends that he and Rita have a bathroom all to themselves. Rita initially denies, saying that the kids have a habit of taking things that they buy just for themselves, but she agrees when she and Lynn Sr. agree to keep their own bathroom a complete secret, and by building it in their closet. However, just when Rita reconsiders going along with the plan, since it means they would have to lie to their children, she and Lynn Sr. discover that the bathroom has become a messy wreck due to the kids' use, which promptly leads to them agreeing to build their own bathroom.
Later, as the siblings go on with their day, Rita and Lynn Sr., donning construction equipment and some tools, attempt to prep up their bathroom without making their kids suspicious. They get their work done through various means, whether it'd be making loud noises to block out the noise of their construction, keeping their kids out of their room, and hiring some extra workers. After a lot of hard work, Rita and Lynn Sr. finally complete their secret bathroom, and love how they now have something all to themselves.
The next day, the siblings are in a hurry to get to school, but Lana is running behind. Lana is trying to find her lucky chicken bone, but is forced into leaving by Lori when they're about to be late for school. Upon leaving, Charles runs into the parents' secret bathroom, and coughs up Lana's lucky chicken bone. Sometime later, Rita and Lynn Sr. discover the bone, and fear that their kids know about their secret bathroom, prompting Lynn Sr. to add on locks to the door. Just as Lynn Sr. applies the locks, Cliff runs in, and unravels the toilet roll. Assuming Lynn broke in, Lynn Sr. adds on even more locks. However, Hops, who is chasing after a fly, climbs through the air vents, and splashes water all over the toilet seat. Thinking Lincoln broke in, Lynn Sr. applies even more security features to the bathroom, ranging from surveillance cameras, motion sensors, a laser grid, and a security panel inside, which will lock them in if they ever get caught.
Later, as Rita and Lynn Sr. do their business in their secret bathroom, Lynn Sr. attempts to exit, but finds the door locked. He tries to put in the passcode, but it's incorrect. After several unsuccessful attempts, they end up getting locked in the bathroom. Realizing their dilemma, Rita turns off the shower, but ends up breaking the handle off, causing water to start flooding the bathroom. Rita tries to pry the door open with a toothbrush Dr. Feinstein gave her, but it snaps in an instant. Attempting to escape through the vents, they realize too late that they wired the vents. Realizing that they're out of options, Rita and Lynn Sr. call for their kids to help them, and succeed in breaking them out when Lynn rams a coat rack into the door. Suspicious as to why their closet was full of water, Rita and Lynn Sr. admit that they were tired of having to wait so long to use the bathroom, and wanted their own bathroom all to themselves. With the truth revealed, they agree to let their kids use it, but because of the destruction, the secret bathroom is completely destroyed, and they couldn't afford to fix it, since they used the money to put in the security features. Despite this, the kids still allow their parents to use the upstairs bathroom, even if it means going back to just one bathroom.
The next day, Rita and Lynn Sr. attempt to race to the bathroom, but there's another long line. Not wanting to wait any longer, Lynn Sr. asks Lana for Old Sloshie.
This episode reveals that whenever Rita and Lynn Sr. buy something just for themselves, the kids have a habit of taking it over. This is explained when they once bought an adjustable bed and immediately afterwards, the kids played on it, inevitably damaging it within mere seconds.
This could also allude to "Suite and Sour" since the kids wanted to come along with their parents to the spa resort, inevitably causing trouble.
The idea of Lynn Sr. adding multiple security measures to their secret bathroom is similar to the Loud kids adding numerous security measures to their house in "Lock 'n' Loud". Coincidentally, both episodes are also written by Bob Mittenthal.
This is the second time Lynn Sr. refers to Rita by her first name.
When Lynn Sr. typed in a 4-digit code on the panel, he put in 3-4-8-4. Rita said that the code was one of their kids' birthdays, which hinted that one of the Loud kids was born on March 4th, and the "84" could suggest that one of them was born in 1984.
It could be possible the 3-4-8-4 passcode was for something different, since Rita told Lynn Sr. that it was his idea to make the passcode one of their kids' birth dates, hence why she doesn't know what it is.
Because they have so many kids, Rita and Lynn Sr. find it a hard task to memorize all of their birth dates.
This is the second time Rita referred to Lynn Sr. by his name.
Innuendo: After Rita and Lynn Sr. install a security measure that locks in whoever breaks into their secret bathroom, Rita says that they'll "catch them with their pants down."
Irony: While it appeared that Leni was embarrassed at the fact that the mirror was open the whole time she thought it was "broken", she was actually referring to a chin hair on her face that was embarrassing. It's also worth nothing Lori's reaction, since it appeared that she was sympathetic about Leni doing something foolish, but was proven wrong when Leni was referring to something else.
