Let’s be real — nobody wakes up on a Sunday morning and thinks, “Today is the day I fall in love with a toilet.” But here you are, reading about the best RV toilet upgrade on the internet, and honestly? You’re making a great life choice.
The RV bathroom is one of the most overlooked spaces in any rig, but it’s also one of the most important. After all, nature calls no matter how far off the grid you are. Whether you’re full-timing it on the road or just weekend camping, having a toilet that actually works — and doesn’t smell like a porta-potty at a music festival — makes a huge difference in your RV life.
RV content creator Jared Gillis from the All About RVs YouTube channel recently put out a video breaking down exactly why he thinks the Dometic 310 is the best RV toilet out there. He walked through a full install AND gave 6 solid reasons why this toilet beats everything else in the RV world. Spoiler: it involves porcelain, a soft-close seat, and way less stink.
In this article, you’ll get a full breakdown of all 6 reasons, a quick install guide, a handy comparison table, and some supporting facts to help you decide if the Dometic 310 belongs in your RV bathroom. Trust us — your nose will thank you.

🏆 Reason #1: It Has a Porcelain Bowl (And That’s a Really Big Deal)
The Dometic 310 comes with a full-size porcelain (ceramic) bowl — and that single feature alone puts it miles ahead of most RV toilets. Most RVs come stock with a plastic toilet, which can look and feel cheap, especially after a few months on the road.
Porcelain bridges the gap between that “camping” feel and the comfort of your bathroom at home. RV expert Jared Gillis says the porcelain bowl makes it feel like a higher-quality toilet, and that matters when you’re spending weeks (or months) living in your RV.
According to The RV Geeks, porcelain toilets are also significantly more durable, with some models supporting double or even triple the weight capacity of a standard plastic RV toilet (which typically maxes out at 250–300 lbs).
🪣 Here’s a fun thought: You’ve probably spent more time picking out your RV’s throw pillows than researching the toilet — and yet, one of those items gets used multiple times a day. Rethink your priorities.
🧹 Reason #2: It’s Way Easier to Clean Than a Plastic Toilet
Nobody wants to spend their camping vacation scrubbing a toilet. Porcelain doesn’t scratch the way plastic does, which means dirt, grime, and stains wipe off quickly and easily.
Plastic RV toilets are actually porous — meaning bacteria and odors can seep into the material over time. The Dometic 310’s smooth ceramic finish repels stains and keeps the bowl looking cleaner, longer. According to Reddit’s RV community, ceramic toilets are “definitely easier to clean thoroughly” and don’t require special cleaning products.
The enamel seat on the Dometic 310 is also ribbing-free on the inside, which is a small-but-mighty upgrade. No ribs means no hidden crevices where grossness likes to hide.
😂 Real talk: If you’re still scrubbing a scratched-up, yellowed plastic toilet with a toothbrush and hoping for the best, you might want to ask yourself: Is this really the adventure you signed up for?
🧼 Porcelain vs. Plastic: A Quick Comparison
| Feature | Porcelain (Dometic 310) | Standard Plastic RV Toilet |
|---|---|---|
| Ease of Cleaning | ✅ Very Easy (non-porous) | ❌ Harder (porous surface) |
| Odor Resistance | ✅ Doesn’t absorb odors | ❌ Can trap smells over time |
| Yellowing Over Time | ✅ No yellowing | ❌ Yellows with age |
| Scratch Resistance | ✅ High | ❌ Scratches easily |
| Weight | ⚠️ Heavier (30–50 lbs) | ✅ Lighter (10–15 lbs) |
| Weight Capacity | ✅ Very High | ⚠️ 250–300 lbs typically |
| Cost | ⚠️ Slightly more expensive | ✅ Usually cheaper |
| Home-Like Feel | ✅ Absolutely | ❌ Definitely not |

👃 Reason #3: Say Goodbye to That Funky RV Smell
If you’ve ever walked into an RV bathroom and immediately walked back out, you know the smell we’re talking about. One of the biggest advantages of the Dometic 310’s porcelain bowl is that it is completely non-porous — meaning it does not absorb odors.
Plastic RV toilets can start holding onto smells over time, especially if they’ve been cracked or scratched. The Dometic 310’s ceramic material stays odor-free no matter how long you’ve been on the road. According to RoadTrippers, keeping your black tank valve closed at hookups and using tank chemicals is also key to keeping smells at bay.
Pro tip: Jared also recommends caulking the base of the toilet to the floor after installation, especially if it’s in a wet bath. This extra step seals out moisture and helps prevent odor from sneaking up through any gaps.
😂 Let’s be honest: If your RV toilet smells bad enough that guests start making excuses to “step outside,” it might be time to stop blaming the campground and start upgrading your throne.
🔧 Reason #4: The Inner Seal Is Super Easy to Maintain
Here’s something most people don’t think about until it’s too late — the seal inside your RV toilet is one of the most important parts of the whole system. If it stops working, you’ll have water leaks, bowl drainage issues, and yes, even more smell.
The Dometic 310’s inner seal is incredibly accessible. You don’t have to take the entire toilet apart to clean or replace it. Jared Gillis explains in the video that all you do is turn off the water, pull the seal out, clean it, and pop it right back in. Done.
This is a massive advantage over other RV toilets where seal maintenance requires partial disassembly. According to Camping World’s RV Toilet Maintenance Guide, keeping your toilet seal clean and lubricated is one of the most important things you can do to extend the life of your RV toilet.
😂 Words of wisdom: If maintaining your RV toilet seal feels like performing open-heart surgery, you’ve got the wrong toilet. Life is too short — and too smelly — for that kind of drama.
🪑 Reason #5: The Enamel Seat Makes a Huge Difference
The Dometic 310 comes with an enamel toilet seat — not plastic. This is a bigger deal than you might think. Standard plastic RV toilet seats often have ribbing on the underside, which is basically a collection point for grime, bacteria, and general yuckiness.
The Dometic 310’s smooth enamel seat has none of that. It’s easy to wipe down, and it doesn’t feel flimsy the way cheap plastic seats do. According to a hands-on review from Adventurous Way, “The solid seat and lid are a league above the flimsy plastic of the Thetford toilet.”
Comfort matters too — especially when you’re living full-time in your RV. The Dometic 310 seat is noticeably more comfortable than standard plastic seats, which is something Jared himself strongly agrees with in the video.
😂 Hot take: You spend more time researching which campsite has the best Wi-Fi than you do thinking about what you’re actually sitting on every single day. Maybe that math doesn’t add up.
😴 Reason #6: The Soft-Close Seat Is an Absolute Game-Changer
Soft-close toilet seats. If you’ve ever experienced one, you know exactly why this is on the list. If you haven’t, just imagine gently laying the lid down and watching it drift quietly to a close — like a feather landing on a cloud.
No more 3 AM BANG when someone drops the toilet seat in the middle of the night in your 30-foot Class A motorhome. According to Jared, this feature alone was worth the upgrade, and reviewers across the board agree. “Absolutely love that it’s soft close. Need I say more?” — Jared Gillis, All About RVs.
The soft-close seat also extends the life of the seat itself by reducing the impact damage that happens when a seat is slammed repeatedly. It’s the little things in RV life that make the biggest difference.
😂 Unpopular opinion: If you’re sharing an RV with a partner, the soft-close seat might actually save your relationship. You’ve been warned.
🛠️ How to Install the Dometic 310 in Your RV
One of the best parts about the Dometic 310 is how easy it is to install. Jared calls it easier to install than a standard house toilet — and he’s right! Here’s a simplified step-by-step guide:
📋 Tools You’ll Need
| Tool | Why You Need It |
|---|---|
| Wrench | To loosen and tighten mounting bolts |
| Screwdriver | To pry off the old floor gasket if stuck |
| Rubber Gloves | For hygiene — this is a toilet, after all 🧤 |
| Rag or Bucket | To catch any leftover water |
| Penetrating Oil (like PB Blaster) | If your old bolts are rusted |
| Caulk (optional) | To seal the base of the new toilet to the floor |
🔩 Step-by-Step Install Guide
Step 1: Turn off the water supply. Flush the toilet to drain all the water pressure out of the lines.
Step 2: Glove up early — it’s way easier to put on gloves when your hands are dry!
Step 3: Place a bucket under the water line connection. Disconnect the water supply line.
Step 4: Remove the two mounting bolts on the base of the toilet. If they’re rusty, spray them with penetrating oil first.
Step 5: Lift the old toilet straight up and out. Because RV toilets have no tank or trap, they’re much lighter than a house toilet.
Step 6: Clean the floor around the opening. Remove and replace the old rubber floor seal.
Step 7: Attach the new rubber seal to the bottom of the Dometic 310.
Step 8: Lower the new toilet into place, lining up the bolts. Sit on it or press down to compress the seal, then tighten the bolts 30–40 inch-pounds (snug but not overtight — you don’t want to crack the plastic flange!).
Step 9: Reconnect the water line. Turn the water back on and test flush. Check for leaks.
Step 10 (Optional): Caulk the base of the toilet to the floor for a clean, finished look and extra moisture protection.
💡 RV Pro Tip: RV toilets do NOT use wax rings like house toilets. They use a rubber seal instead — which is actually more forgiving and easier to set correctly.
