Coleman 17B Bathroom Storage: The Cabinet We Added

The Coleman 17B bathroom works, but it has almost no storage, and it is a lot of white. Toilet paper, toothbrushes, and cleaning supplies had nowhere to live. We fixed it with one narrow cabinet beside the toilet, and it made our list of the top 10 things we would buy again.

The problem: almost no bathroom storage

The 17B packs a full bathroom into a small floor plan. The tradeoff is space. There is no real spot for spare toilet paper, toiletries, or the cleaning and tank supplies you need on every trip.

It also felt clinical. White walls, a white toilet, and nothing else.

The cabinet we added

We added this narrow bathroom cabinet with a toilet paper rod. It fits in the gap between the toilet and the wall, and the wood-look finish is a close match to the factory cabinets and door in the 17B.

What it gives you, top to bottom:

An upper cabinet with a door.
A small drawer.
An open shelf.
A toilet paper holder, right where you need it.
A lower cabinet with a door.
A flat top for a small decoration. Ours has a little faux lavender plant.

The double hook on the wall is the one that came with the camper. Between the hook and the cabinet, the bathroom finally has a place for everything, and it looks finished instead of empty.

How we secured it for towing

A tall, narrow cabinet will tip or walk around the first time you hit a bump on the highway. We screwed ours to the wall so it stays put while we tow.

If you do the same, take your time finding a solid spot. Camper walls are thinner than house walls, so make sure your screws are biting into something that will hold, and check it after your first trip.

What we keep in it

Toilet paper. One roll on the holder, and spares in the cabinet so nobody has to yell for a new roll.
Toiletries. Toothbrushes, toothpaste, soap, and the rest of the daily stuff.
Cleaning and tank supplies. Wipes, cleaning spray, and black tank treatment, so they are in the bathroom where we actually use them.

Tips before you buy one

Measure the gap first. Measure between the toilet and the wall, and the depth from the back wall, before you order. It fits our 2025 17B, but floor plans and model years vary.
Plan to anchor it. Do not count on it staying put on its own. Budget a few minutes and the right screws to secure it.
Put heavier things down low. Bottles and refills belong in the lower cabinet so the top stays light.
Take the decor down for travel if it is not secured. A plant on top looks great at the campsite, not so great on the floor after a pothole.

Coleman 17B bathroom storage FAQs

Does the Coleman 17B bathroom have storage?

Very little. There is no real spot for spare toilet paper, toiletries, or cleaning supplies, which is why we added a narrow cabinet beside the toilet.

What cabinet fits next to the toilet in a Coleman 17B?

We use this narrow bathroom cabinet with a toilet paper rod. It fits the gap between the toilet and the wall in our 2025 17B. Measure yours before you order.

Will a bathroom cabinet tip over while towing?

It can if it is not secured. We screwed ours to the wall so it stays in place on the road.

What do you keep in the camper bathroom cabinet?

Spare toilet paper, toiletries, and cleaning and tank supplies like wipes, cleaning spray, and black tank treatment.

Will this work in other small campers?

Probably, if you have a similar gap next to the toilet. Measure the width and depth first and plan to anchor it to the wall.

Final thoughts

This is a simple add-on, but it gave a tiny bathroom real storage and made it feel finished. Measure your gap, screw it to the wall, and you are set.
