Purchasing an RV is a big deal—honestly, for most people, it’s one of the largest purchases they’ll ever make. Because of that, it’s worth slowing down and really thinking through what you want and need before you pull the trigger.

Now, most people focus on things like floor plans, towing capacity, or sleeping space—but there are a few areas that don’t always get enough attention. One of those is the bathroom. And believe it or not, it can make a huge difference in your day-to-day comfort.

At first, you might think, “A bathroom is a bathroom…how different can it really be?” But in the RV world, that’s not the case. There are actually two main types—wet baths and dry baths—and they are very different from each other.

And here’s the thing—whichever one you choose will directly impact your daily routine and overall experience living in your RV. So it’s definitely worth understanding both before you decide.

The biggest differences between these two come down to size, layout, and how you use the space. One gives you more room and flexibility, while the other saves space and keeps things compact. Like most things in RVing, there are trade-offs either way.

The good news is—no matter which you prefer, there are plenty of RVs out there with both options. The key is just doing a little homework and figuring out what fits your lifestyle best.

What Is an RV Wet Bath?

A wet bath is probably not what you’re used to if you’re thinking about a typical home bathroom. It’s a completely different setup.

The easiest way to think about it is this—the entire bathroom is basically the shower.

That’s actually where the name “wet bath” comes from. When you take a shower, the whole space gets wet—not just one section of it.

Now, that doesn’t mean it’s just a shower. You still have a toilet and a sink in there. But there’s no separate shower stall—everything shares the same space.

At first, that might sound a little strange, but there are some real advantages. The biggest one is how compact it is. Because everything is combined, it takes up way less space in your RV.

And that means more usable living space everywhere else—which is a big deal, especially in smaller rigs.

Another nice bonus is that when you’re actually showering, you have more room to move around compared to a tiny enclosed shower. You’re using the entire bathroom instead of being stuck in a small corner.

Maintenance is a little different too. Since everything gets wet regularly, the bathroom tends to stay cleaner with less effort day-to-day.

That said, there are a couple things to stay on top of. You’ll need to dry things out after showering to prevent mold, and anything like toilet paper or towels needs to be protected—or it’ll get soaked pretty quickly.

So it’s simple and efficient, but it does require a slightly different routine.

What Is an RV Dry Bath?

A dry bath is what most people picture when they think of a bathroom. It’s basically the same setup you’d have at home.

Everything has its own space—the shower is separate from the toilet and sink, and nothing overlaps.

Because of that, dry baths are usually larger. And with that extra space comes more storage, which is always a win in an RV.

The trade-off is that a bigger bathroom takes up more room in your RV overall. So you’re giving up some living space in exchange for a more traditional bathroom setup.

One of the biggest advantages is convenience. You don’t have to worry about everything getting wet, covering items, or drying things down after every shower.

But since the whole bathroom isn’t getting rinsed regularly like in a wet bath, you’ll typically spend a bit more time cleaning it.

Where dry baths really shine is when you’re traveling with a partner. Two people can use the bathroom at the same time—one can shower while the other brushes their teeth or gets ready.

And when you’re on the road with a full day ahead, that can be a huge time saver.

RV Wet Bath vs Dry Bath – Which Is Better?

So which one is better?

Honestly—it comes down to personal preference.

That said, most RVers tend to lean toward dry baths. And the biggest reason is simple—they feel familiar.

If your RV bathroom feels like your bathroom at home, it just makes the whole experience more comfortable, especially when you’re new to RVing.

The extra space is another big plus. Being able to move around more easily—or have two people getting ready at the same time—makes a noticeable difference.

Yes, you lose a little space elsewhere in the RV, but for a lot of people, it’s worth it.

Another advantage is not having to dry everything down after every shower. Over time, that can add up to a lot of effort in a wet bath.

And since most of the bathroom stays dry, you also don’t have to worry as much about moisture or mold issues.

So for comfort and convenience, dry baths usually win—but wet baths definitely have their place, especially in smaller RVs.

Can You Use a Composting Toilet in an RV Wet Bath?

Yes—you can install a composting toilet in a wet bath.

That said, there are a couple of extra steps involved. You’ll want to make sure everything is sealed properly so water doesn’t get where it shouldn’t—especially into the base or mounting area.

You may also need to modify the setup slightly so any water that gets in can drain out properly.

Another option is simply covering the toilet when you shower, which is often the easiest solution.

So it’s definitely doable—it just takes a little planning and attention to detail. If you’re handy, you can tackle it yourself. If not, a professional install is always a safe route.
