There never seems to be enough storage space in a camper, but these clever RV bathroom storage ideas can help you stay organized no matter how tiny your bathroom is.
RV Shower Solutions
Some RV showers offer built-in shelves, but because there is rarely a railing to keep items in place, extra shower storage is a must. These are great plahces to start:
Pocket Shower Caddy
This hanging shower caddy can be hung over a shower curtain rod or a glass shower door. Put one on the inside of your shower for shampoo and conditioner, and one on the outside for hair accessories, makeup, deodorant, and other toiletries!
Wire Shower Caddies

If you're looking for something a little more sturdy, you might prefer a metal shower caddy. These can actually be hung over any type of door, and again, can be used on the inside or outside of the shower.
The multi-level shower caddy shown above is one of the best shower caddies I've seen for a large family (or anyone who has a lot of shower products!).
Even though the style of wire basket shown below is designed to go over a cabinet door, they fit great inside my RV shower.

Add a Tension Rod to an RV Shower
If you don't have anywhere to hang a caddy, you can add a tension rod spanning across the back wall of your shower to create a place to hang storage baskets with no damage to your RV walls.
Wall Mounted RV Shampoo Dispenser
Ever-popular with RV owners, a wall-mounted shampoo and soap dispenser eliminates the need for storing bottles altogether.
Tension Shelf

A classic corner shower shelf like this one is wonderful if you have space for it. A shower isn't the only place a corner shelf can be used to add extra storage, either. I have one in another corner of my bathroom and another one in the corner of my RV living room that I set decor on.
My RV has shelves in the shower, so I made “walls” out of plexiglass to prevent items from falling off the shelves while the RV is moving. As an added bonus, the walls make it easier to store bottles upside down when they are almost empty.

Adhesive Caddies
These adhesive caddies can be placed wherever they are needed. I have personally used these and let me tell you, if you have any doubts about whether or not they will stay stuck to the wall, you do not need to worry! The adhesive is SUPER strong.
Their use is not limited to the shower, either…you could stick one to a mirror, refrigerator door, stove backsplash, window, or any smooth surface in your RV where you'd like to add some extra storage.
Using Doors to Organize Your RV Bathroom

This over-the-door storage organizer is so useful that I have three of them in my RV.
Also in this picture you can see how I used a tension shower shelf in the corner of my RV bathroom for storing toilet paper. The plant is stuck to the top shelf with acrylic mounting tape so it can stay right there while the RV is moving.
Towel Rack for Hanging Towels in Your RV

Over the door is a good place to hang towels, either for daily use or for storage. An over-the-door ladder-style towel rack like this one may be hung on a glass shower door or wall, as well.
Personally, I prefer to hang towels on hooks instead of a towel bar because I find it easier. An over-the-door coat rack makes it possible to hang several towels on a single door.
A wine bottle storage rack can also be hung on an RV bathroom door for storing rolled-up towels.

Robe Hook on an RV Bathroom Door
Since it's just me and my husband in our RV, I prefer just a single robe hook for hanging my husband's towel on our bathroom door.

I chose to screw a metal one to the door that matches the hardware in my bathroom instead of using a cheap-looking plastic Command hook so that it would look like it belonged and add rather than detract from the value of the RV.
I've not had any issues with it coming loose, even though the door is hollow.
DIY Hooks On Bathroom Wall

We love what RV renovator Rachel Reed did to create storage and style to her RV bathroom! She found hooks that matched her RV decor and attached them to a strip of wood, making them more secure. Now her wall is perfect for drying towels or hanging your robe.
Over-the-Door or Wall Mounted Jewelry Cabinet
This cabinet can be hung on a door or mounted on the wall. It's made for jewelry, but it can also fit makeup and other small bottles. Plus when closed it doubles as a mirror.
Using Cabinet Doors for Adding Storage to Your RV Bathroom
Cabinet doors are another good place to add extra storage.
Make sure you measure the width of any over-cabinet organizers to make sure they will fit on your cabinet door and allow plenty of clearance on both sides for the door to swing shut.
Classic Over-the-Cabinet Caddy

The company that makes this caddy sells several different styles of over-cabinet organizers in varying sizes and depths, which you can see here.
DIY Cabinet Organizer

One clever RV owner used wire Command hooks to hang inexpensive storage baskets on the door of her bathroom cabinet.
Shoe Caddy Used to Organize an RV Bathroom Cabinet
One RV owner cut and hung a shoe organizer on the inside of a cabinet door. This would make a great place to store smaller items like scrunchies and headbands.

This RVer also used this 2-Tier Under Sink Organizer for extra organization. It adjusts to whatever width you want and leaves room for pipes under the sink.
Towel Bars for Cabinet Doors
I have two of these towel bars – one on a cabinet door for my hand towel, and one on the inside of my shower door where I hang a towel I use as a bath mat.
Check Dollar Tree for these; I have found one there that adjusts in length. You can see it here, but unless you want 24 of them, you probably won't want to order it online!
Adding Vertical Storage to RV Bathroom Walls
Any time an RV owner mentions that he or she hung something on the wall, someone wants to know how it was hung.
For some heavier items, the best way, used by many RV owners including myself, is to use screws. However, unless you can find a stud to drill into, you run the risk of the screw stripping out of the wall, like in the picture below.

This towel bar was either factory installed or hung by our RV's previous owners, and the small plastic wall anchors started pulling out of the holes with the constant tugging of pulling a towel off the rack.
In order to fix this towel bar, I used metal self-drilling wall anchors designed for hollow doors and now it's very sturdy. Here's a video demonstrating my fix:
I understand that some RV owners are against the idea of drilling holes in the wall. For some other options, I suggest that you check out this post: 8 No-Drill Wall Hanging Methods.
If you would still prefer not to drill holes, there are quite a few adhesive products on the market for storing and organizing, such as these wire baskets:
One RV owner accomplished the same thing by using Command hooks to hang cheap wire baskets from the dollar store:

Once you've figured out how you plan to hang things on your walls, here are some ideas for what to hang on them.
Wicker Baskets Hung on Walls
Hanging a pair of cute baskets on your wall would be a good way to add extra storage in your RV bathroom, like these RV owners did:

Mason Jars Mounted on the Wall

Mason jars can also make for attractive and functional wall storage. You can learn how to make something like this here.
Organization Rail with Hooks

These hanging storage buckets were purchased at Ikea. If you aren't near an Ikea, you can also get this rail storage system (called “Fintorp”) on Amazon….or one like it that's cheaper.
A similar system was improvised in this RV by attaching wire to Mason jars and an inexpensive plastic basket and hanging them from a towel bar. You could try this idea using an adhesive towel bar and S hooks if drilling holes is a concern.

Shoe Organizers Used to Add Storage to Bathroom Walls

One creative RV owner added non-permanent shelving to her bathroom by hanging a closet organizer from a tension rod.
As I mentioned before, shoe organizers can be cut up and used in various locations throughout an RV.

Wine Bottle Rack
A wine rack like this one is a good RV towel storage option and looks nice on the wall, especially if your towels follow a particular color theme.

DIY Permanent Shelves
If you're handy, it doesn't get better than building custom shelving to fit your RV and your needs.

Rachel Reed fully customized this RV bathroom with a shelf above the mirror, a mirror with a built-in shelf, and floor-to-ceiling shelving.
Rachel is a professional renovator and is actually available for renovation coaching, if you're thinking of tackling a customer RV bathroom remodel like hers.

Adding Storage to the Bathroom Vanity
Many items in a bathroom need to be within easy reach of the sink. Here are some ways to maximize the space in that area without putting things away each time you hit the road.
Filling the Gap Between the Sink and Shower

The owners of this RV were constantly having things fall into the space between the sink and shower where they were difficult to reach, so they added an extension to the countertop that not only prevents things from falling but adds extra space to set things. Notice their use of a wire caddy as wall storage.
Here is another idea for utilizing that same area, an otherwise useless gap between the shower and cabinet:

Wall Mounted Soap Dish
If you like to use bar soap, you can free up space on the counter by mounting a soap dish to the wall. Okay, I'll be honest—I just really love this soap dish!
Drawers for Organizing Small Items
These wooden drawers could be mounted to the bottom of a cabinet for storing things like cotton balls, ponytail holders, and contact lenses.

Another idea for storing small items is with plastic drawers like these. You could use acrylic mounting tape to stick them to your countertop to keep them from sliding around.
Towel Bar Used for Countertop Organization
An adhesive towel bar in this RV keeps these items from sliding off the counter while an RV is in motion.
Wire Shelf Mounted Above Corner Sink

The owners of this RV cut the legs off a corner shelf, spray painted it, and hung it using Command hooks. A couple of adhesive corner wire shelves would work, too.
Around the Toilet
Toilet Paper Storage
I love this style of basket for extra toilet paper storage that is both cute and functional. Or if you're a toilet reader, you could keep magazines in the basket as well.
Another toilet paper storage option: this is actually a cheap plastic bag holder from Ikea (also available on Amazon).

Narrow Cart
If you have a narrow space in your bathroom, a rolling shelf like this might fit:
Over Toilet Shelf
And an over-toilet shelf like this one would be a good way to make use of empty wall space above the toilet. You could use some pieces of acrylic mounting tape to adhere it to the wall and keep it from tipping over while your RV is moving.
RV Bathroom Cabinet Organization

The owner of this RV added plexiglass to keep items that have shifted around during transit from falling out of the cabinet when the doors are opened. These could be easily installed using clear acrylic mounting tape, which is easily removable.
(I know I've mentioned this mounting tape several times…I use it for everything!)
Small organizational baskets, which can be purchased at Dollar Tree or Walmart, can help save space in a cabinet and keep things from shifting around. Command hooks can be used to mount them on the back wall of a cabinet to make use of vertical space, like I did in my RV medicine cabinet, shown below:

Here's an example shared by another RV owner:

You don't have to buy plastic organizers for your cabinets…this RV owner repurposed Kleenex boxes to organize a cabinet in her RV.

Elastic and staples keep this bathroom medicine cabinet neat and tidy, even when the RV is in motion.

Hooks on the Back of a Cabinet Door

Even the back of a cabinet mirror can be used for storage! This wasn't originally my idea, but I decided to try it.
I hung necklaces on the back of my medicine cabinet door using these Command hooks (which I had already spray-painted for a different project). If you do this, just be sure to stick the hooks where they won't bump the shelves when you close the cabinet.
One RV owner who tried this idea taped a sheet of bubble wrap to the back of the mirror to keep her necklaces from banging against the hard surface every time the door was opened and closed. A piece of felt would probably work nicely for that purpose as well.

Another way to use the back of the mirror for storage is to attach adhesive magnetic tape to the back of a cabinet door to hold small metal items such as bobby pins and hair clips, as shown below.

I hope you enjoyed these ideas and found them useful! Happy organizing!

So many great ideas. I love the shower curtain with pockets in it. The only thing I hate about some of the hanging organizers is that they only have one hook. The ones with two hooks are best but hard to find in store. Amazon is the best. Love this list, been trying to find some thing to fit some interesting shapes and places in my RV! The van life can be small so space it everything 🙂
The newer trailers do not have a bathroom sink in them. Suggestions in lieu of bathroom sink?
Are you asking what you can use instead of a sink? If so, I’m not sure what to recommend…I haven’t seen a trailer with no sink in the bathroom or at least in the bedroom next to the bathroom. Is there a shower?
I had a forest river 2018, Wildwood , FSX, 19 ft, no sink in restroom. Toilet and shower only . But kitchen sink was close so I washed my hands there. You can keep wet wipes in toilet area til you finish then wash your hands. But don’t forget to use soap and water to keep you and others healthy .
Great idea! Some hand sanitizer could go in there as well.
You can find shallow bowls or buckets to mount. They won’t have running water but maybe a small collapsible pitcher filled elsewhere. Probably easiest to just use the kitchen sink.
There is a small tub /shower and toilet
Hi, our smaller trailer is the same. No sink in bathroom. I keep hand soap by the tub. Looking for a small plastic container with a spout to sit in tub (maybe on a small stand). I can fill it when we stop. Still kicking around ideas. I would rather wash my hands before I leave the bathroom.
A laundry detergent dispenser with a spout on it might work for you. I keep one in my truck for washing up after messy farm chores.
That’s a great idea! Thanks!
I use a gal thermos with screw top lid and beverage dispenser outside. Fill with warm water and stays washable temp all day. Could easily be used inside on a stand.
It’s hard to say
Doing a make over of our older motorhome. Got the bathroom mostly done and organized, but would love some tips on where to put the toilet paper. Our bathroom never had a toilet paper holder in it since the space is quite small with a tight toilet area, a little bit of counter top for the sink (one of the places where I would sit the paper at) and no leg room. I bought one of those hang over the door roll holders that I put on the cabinet door under the sink, but it gets in the way when someone is using the toilet and sticks out when trying to get in and out of the shower. There is no space to hang it on the wall next to the toilet unless you want to turn yourself totally around when “using” the toilet… and there is no space on the floor to put a free standing one either. I kiddingly said that I would hang it from a rope coming down from the ceiling… but at this point, that’s about all I can think of…..that or get used to moving the roll everytime we are done with it.
Haha that does sound annoying! Maybe you could email me a picture of the space and I can see if I can come up with any other ideas? You can email me at admin {at} rvinspiration {dot} com. 🙂
My RV bathroom doesn’t have a TP holder either so I loop a rope through the toilet roll and then hang it off the cabinet knob
Very good info thanks so much!
Love these ideas. Have followed you for awhile now and soon I’ll be purchasing a class c. Narrowing down brands. 3 years of research. Caregiver for last 2 years and now downsizing. Excited and scared at the same time.
Thank you are your inspiration.
C.
Aw, thank you for your kind words! Good luck with your Class C and hope you have fun! 🙂
Hi Ashley, thank you for your great inspirational ideas. Wow, who knew so many clever ideas! Do you have any storage/organization ideas for underneath the camper for the chairs/grill, etc? We try to keep it as neat as possible but it is hard. We have a fifth wheel with abundant room but gets messy.
I am actually not very good at organizing underneath the RV myself, but my friend Breanna has some good ideas in a post on her blog.
