Anyone who’s spent more than a few days in a campervan knows the bathroom is where things go wrong first. It’s a tiny, enclosed space that gets wet multiple times a day, and if you don’t stay on top of it, the smell and the mould will catch up with you fast.

The good news is that keeping a campervan wet room fresh doesn’t take much effort. It takes the right habits and a few smart choices when you’re kitting out the van. Here’s what actually works, from daily routines to the materials that’ll save you scrubbing time later.
Get the Air Moving After Every Shower
Ventilation is everything in a small wet room. After a shower, the moisture has nowhere to go unless you give it a way out. If your van has a roof vent or extractor fan above the bathroom, run it for at least 10 to 15 minutes after you’ve finished. If you don’t have a fan, crack a window or prop the bathroom door open and open a vent elsewhere in the van. You want to create airflow, not just an opening.
On warm days, this happens naturally. On cold, damp mornings in Wales or Scotland, you’ll need to be more deliberate about it. A small rechargeable USB fan pointed at the wet walls will help dry things out faster than you’d expect.
A Two-Minute Daily Wipe Goes a Long Way
You don’t need a full cleaning session every day. What you do need is a quick wipe-down. Keep a microfibre cloth or a small squeegee in the bathroom and run it over the walls and floor after the last shower of the day. This removes the standing water that mould feeds on.
Once a week, give the surfaces a proper clean with a mild bathroom spray. Avoid anything too abrasive, especially if your walls are coated or clad. A standard anti-bacterial spray and a soft cloth will do the job without damaging finishes.
Pick Materials That Won’t Hold Moisture
This is where a lot of DIY van conversions go wrong. Plywood, MDF and standard wall panels might look fine at first, but they absorb moisture over time. That leads to swelling, peeling and, eventually, black mould growing behind the surface where you can’t reach it.
Many professional converters now fit high-quality PVC hygienic wall cladding sheets in campervan wet rooms. They’re completely waterproof, lightweight and non-porous, so water just runs off and there’s no surface for mould or bacteria to grip onto. They’re also easy to wipe clean, which ties in well with that daily two-minute routine.
If you’re building or refitting a van, the wall material you choose for the bathroom will determine how much maintenance you’re dealing with for years to come. Get this right early and you’ll thank yourself later.
Use Quick-Dry Accessories
The towels, mats and shower curtains inside your campervan bathroom matter more than you might think. Standard cotton towels take ages to dry in a confined space and will start to smell musty within a couple of days.
Switch to microfibre towels that dry in a fraction of the time. Hang them outside the bathroom after use if you can, even just over the back of a seat with a window cracked. For bath mats, look for quick-dry options or silicone mats that don’t absorb water at all. And if you use a shower curtain, make sure it’s spread out after each use so it dries flat instead of bunching up and trapping moisture in the folds.
Watch for Hidden Damp Spots
Even with good ventilation and clean walls, water can find its way into places you don’t check often. The base of the shower tray, the seal around your toilet, behind any freestanding storage, underneath bottles of shampoo that sit on a shelf all season. These are the spots where mould quietly takes hold.
Every week or two, move things around and check the corners. Run your hand along the seals and look for any discolouration. Catching it early means a quick wipe with a mould remover. Leaving it means a much bigger job down the line.
Don’t Forget the Drain
Campervan shower drains are small and they clog easily. Hair, soap residue and dirt build up quickly, and a slow drain means water sitting in the tray longer than it should. That standing water is a breeding ground for bacteria and bad smells.
Pick up a small drain cover or hair catcher and clean it out after every shower. Once a week, pour a bit of bicarbonate of soda followed by white vinegar down the drain. It’ll fizz, break down any buildup and keep things flowing properly without harsh chemicals.
A Fresh Van Makes a Better Trip
Keeping a campervan bathroom clean isn’t complicated, but it does need consistency. The people who struggle with it are usually the ones who leave everything until the end of the trip and then spend an afternoon scrubbing. The ones who keep on top of it barely notice the effort.
Good ventilation, a daily wipe, the right wall materials and a few quick-dry swaps will keep your wet room smelling fresh from the first day to the last. And when you’re parked up somewhere beautiful with a hot shower waiting, that’s exactly how it should be.
