In order to be comfortable for an entire night of sleep, the bathtub must be long enough for you to stretch out in and wide enough that your shoulders won’t be cramped and you can keep your spine in alignment so your back won’t hurt in the morning.

Sleeping on the floor actually has some health benefits and can be good for an achy back!

Avoid using the bathtub for several hours before bedtime if possible. If the tub is still wet from someone’s shower, dry it with a towel. You can also use a hairdryer to completely dry the tub. Clean the tub so you won’t get any soap residue or hair on your blankets and pillows. [4] X Research source

Remove toiletries (shampoo, conditioner, soap, body wash, lotion, etc. ) that are in the way or that you might accidentally knock onto the floor while you sleep. Be courteous with other people’s belongings and make sure you replace everything in the morning.

Find as many comforters, blankets and pillows as you can. A sleeping bag as the top layer is also a great option.

Fold several blankets or comforters and place them along the bottom of the bathtub. This will create a mattress for you to sleep on. Make sure your padding reaches up the sides of the tub as well if possible to cushion all parts of your body that will be in contact with the tub’s surface. Place a pillow at the end of the tub where you will have your head. You may want to use one pillow under your head for proper support and spine alignment and place one standing up between the top of your head and the end of the tub so you don’t bump your head in your sleep.

Since you don’t know whether the bathroom will be warmer or colder than you are accustomed to during the night, have several layers handy just in case. [6] X Research source A sleeping bag can do double duty as a pad underneath you and a cover on top of you. [7] X Research source

Gather your clothes and toiletries for the next day and place them on a shelf or somewhere where they will stay dry. Find an outlet for your phone. Make sure you will be able to reach your phone from the tub so you can see what time it is and use it as an alarm in the morning. Bring in anything you will use to entertain yourself, like a tablet, laptop, or a book to read.

Decide what you will do if someone else needs to use the bathroom during the night. Agree on what time will be reasonable for you to wake up and get out of the bathtub so others can use it for showers in the morning. [8] X Research source

Use the fan for white noise if you need to block out background noise to sleep better. [9] X Research source Turn out the lights. If you think you might wake up and be disoriented, use a nightlight. That will also help your roommates in case they forget you’re in there and you startle them.
