An elongated porcelain RV toilet can make a compact bathroom feel more like home, but the right choice depends on more than bowl shape. Check the toilet’s height, mounting pattern, available space, flush controls, and the material of both the bowl and base before you buy. These four options range from a true porcelain bowl with an adjustable foot-pedal flush to a taller model with an enamel-coated interior.
| Toilet | Key features | Best for |
|---|---|---|
| SEAFLO Porcelain RV Toilet | 19-inch residential height, elongated porcelain bowl, adjustable gravity flush | Comfort and water control |
| Dometic Model 420 Platinum | Elongated porcelain bowl, 18-inch chair height, universal two-bolt mount | A compact replacement with a porcelain bowl |
| Voyager Plus Residential Height RV Toilet | Porcelain bowl, foot pedal, cold-weather valve rated to -40°F | Cold-weather travel |
| AW 20-Inch High-Profile RV Toilet | Enamel-coated interior, HDPE body, foot-pedal flush | Taller seating and a lighter alternative to an all-porcelain toilet |

Our Picks: Best Elongated Porcelain Rv Toilet reviews
SEAFLO: An Elongated Porcelain Bowl with Adjustable Foot-Pedal Flush
The SEAFLO pairs a non-porous elongated porcelain bowl with a lightweight plastic base. Its 19-inch height gives it a residential-style feel, while the gravity-flush system uses a foot pedal that lets you adjust water flow. SEAFLO also lists a four-year limited warranty.
The toilet measures 20.51 by 14.17 by 19 inches, so compare those dimensions with your bathroom before ordering. The manufacturer describes its tri-directional flush as providing broad bowl coverage while using minimal water. The soft-close seat and cover are useful in a shared RV bathroom, where a slamming lid can be especially noticeable.
This is a strong fit if you want a genuine porcelain bowl, a taller seat, and hands-free flush control. The base is plastic rather than porcelain, which helps keep the unit lighter, but shoppers seeking an all-ceramic construction should keep that distinction in mind. You’ll also need to confirm that your existing plumbing and mounting setup are compatible.
Pros:
- Non-porous elongated porcelain bowl
- 19-inch residential height
- Foot pedal allows adjustable water flow
- Soft-close seat and listed four-year limited warranty
Cons:
- Plastic base may not suit buyers looking for an all-porcelain toilet
- Its dimensions still need to be checked against your RV bathroom
Verdict: Choose the SEAFLO if you want a true porcelain bowl, residential-style height, and adjustable foot-pedal flushing in one package.
Dometic Model 420 Platinum: A Porcelain Upgrade with a Compact Rear Profile
The Dometic Model 420 Platinum has an elongated premium porcelain bowl and an 18-inch chair-height design. Its compact rear profile is intended to save space, a helpful detail in an RV bathroom where floor area is limited. The soft-close seat and lid include a position-lock hinge designed to hold the lid up when needed.
Installation compatibility is a key selling point: the toilet uses a universal two-bolt mount and is designed for standard RV rough-ins of 7.625 inches or greater. Dometic describes it as a replacement option for many competitor toilets and other models in its 400 Series. Still, measure your existing rough-in and check the mounting arrangement rather than relying on the word “universal” alone.
Compared with the SEAFLO, the Dometic has a slightly lower listed seat height and emphasizes replacement fit and a compact rear shape. The product details provided do not specify a flush-control style or overall dimensions, so confirm those details if they matter to your setup. Its fit claims also do not eliminate the need to check the actual floor flange and available clearance.
Pros:
- Elongated porcelain bowl with a scratch-resistant surface
- Compact rear profile designed for tighter layouts
- Two-bolt mount is designed for standard RV rough-ins of 7.625 inches or greater
- Soft-close seat and position-lock hinge
Cons:
- Mounting compatibility should be confirmed with your existing rough-in
- Flush-control details and overall dimensions are not specified in the supplied product information
Verdict: Consider the Dometic if a porcelain bowl and a space-conscious replacement design are your priorities, but verify your flange and mounting measurements first.
Voyager Plus: A Residential-Height Porcelain Toilet for Cold-Weather Use
The Voyager Plus is described as a full-height RV toilet with a porcelain bowl, foot-pedal flush, and adjustable water flow. Its main distinction is a built-in water valve designed to operate in temperatures down to -40°F, making it the most clearly cold-weather-focused option in this group.
The product details also list a soft-close seat and lid and a support capacity of up to 660 pounds. Those features may appeal if you want a sturdy, home-style setup for trips in very cold conditions. However, the supplied information does not give a specific seat height, overall dimensions, or mounting pattern, so you’ll need to confirm those details before treating it as a direct replacement for your current toilet.
Compared with the SEAFLO, the Voyager Plus shares the porcelain bowl and adjustable foot-pedal concept but stands out for its stated cold-weather valve performance. If you mostly camp in mild conditions, that specialized feature may matter less than clear fit information. The product title names Dicor, while the listed product name is Voyager Plus, so check the product listing details carefully before purchasing.
Pros:
- Porcelain bowl with an elongated, full-height design
- Water valve specified to operate down to -40°F
- Foot pedal offers adjustable water flow
- Soft-close seat and lid
Cons:
- Specific dimensions and mounting details are not included in the supplied information
- Its cold-weather feature may be less important for warm-weather-only trips
Verdict: The Voyager Plus is worth considering for cold-weather RV use, provided you confirm its dimensions and mounting fit before buying.
AW 20-Inch High-Profile Toilet: Taller Seating with an Enamel-Coated Interior
The AW is a high-profile RV toilet with an elongated seat, foot-pedal flush, and a listed 20-inch height. Its construction differs from the true porcelain-bowl models above: the body is HDPE, and the inner surface is described as porcelain enamel. That smooth, ceramic-like finish is intended to resist stains and buildup, but it is not the same construction as a solid porcelain bowl.
The foot pedal operates a gravity flush with two-directional nozzles. The taller seat may be easier to use for people who prefer more height, though it also takes up more vertical space. Before ordering, the manufacturer asks buyers to confirm 6 11/16-inch bolt spacing and less than 1/2-inch protrusion above the floor. These specific fit requirements make careful measurement especially important.
This option may suit you if you want a tall seat and a lighter body material rather than a porcelain bowl throughout. It includes a soft-close seat and is described as a do-it-yourself installation, but fit depends on matching the stated bolt spacing and floor-flange details. Compared with the porcelain-bowl options, its central trade-off is clear: an enamel-coated interior and HDPE body instead of a porcelain bowl.
Pros:
- 20-inch listed height for a taller seating position
- Elongated seat with soft-close lid
- Foot-pedal gravity flush with two-directional nozzles
- HDPE body with a smooth enamel-coated interior
Cons:
- It has an enamel-coated interior, not a solid porcelain bowl
- Requires specific bolt spacing and floor-protrusion measurements
Verdict: Choose the AW if you value a taller seat and an HDPE body, but skip it if a true porcelain bowl is a must-have.
How to Choose an Elongated Porcelain RV Toilet
Confirm the bowl and body materials
“Porcelain” can refer to the bowl, while the base or body may use a different material. The SEAFLO, Dometic, and Voyager Plus are described as having porcelain bowls. The AW instead has an HDPE body with an enamel-coated inner surface. If you want a true porcelain bowl, check the material description closely rather than relying only on a product title or the word “ceramic-like.”
Measure the rough-in and mounting points
RV toilets are not automatically interchangeable just because they are made for recreational vehicles. Measure the distance from the wall to the floor flange and check the bolt spacing and flange height. The Dometic specifies a two-bolt mount and a standard rough-in of 7.625 inches or greater. The AW calls for 6 11/16-inch bolt spacing and less than 1/2-inch protrusion above the floor. Confirm the measurements for any model before removing your current toilet.
Check overall height and bathroom clearance
A taller toilet can be easier to sit on and stand up from, but it may not fit every RV bathroom comfortably. The listed heights are 18 inches for the Dometic, 19 inches for the SEAFLO, and 20 inches for the AW. The Voyager Plus is described as residential height, but its specific height is not included in the supplied details. Also measure the available space around the bowl, seat, door, and nearby fixtures.
Choose the flush control that suits your routine
The SEAFLO, Voyager Plus, and AW use foot pedals, with adjustable water flow described for the SEAFLO and Voyager Plus. A foot pedal keeps flushing hands-free and can give you more control over water use on those models. The supplied details for the Dometic do not specify its flush-control style, so check the listing if that feature is important to you.
Match special features to your travel conditions
Think about where and when you use your RV. The Voyager Plus is the option with a valve specified to operate down to -40°F. The SEAFLO lists a four-year limited warranty, while the Dometic emphasizes its compact rear profile and replacement fit. These features can help narrow your choice, but they do not replace checking the toilet’s physical fit in your bathroom.
Compare cleaning and everyday comfort details
A smooth porcelain or enamel-coated surface can be easier to clean than a rough or textured interior. Seat height, bowl shape, and a soft-close lid also affect daily comfort. All four options are described as elongated, but their heights and materials differ. Consider who will use the bathroom most, how much space you have, and whether a soft-close seat is a priority.
Frequently Asked Questions
What is the best elongated porcelain RV toilet in this list?
The SEAFLO is the most balanced pick if you want a porcelain bowl, residential-style height, an adjustable foot-pedal flush, and a listed four-year limited warranty. The best choice for you still depends on your bathroom’s mounting measurements and clearance.
Is the AW toilet made of porcelain?
The AW has an HDPE body with an enamel-coated inner surface. It is described as having a smooth, ceramic-like finish, but the supplied product details do not describe it as a solid porcelain bowl.
How do I know whether a replacement toilet will fit my RV?
Measure your existing rough-in, bolt spacing, flange height, and the space around the toilet. Compare those measurements with the product’s fit requirements. The Dometic and AW provide specific mounting guidance, while the supplied details for the Voyager Plus do not list a mounting pattern.
Which option is designed for cold weather?
The Voyager Plus has a built-in water valve specified to operate down to -40°F. That feature may be useful for cold-weather travel, but you should still follow the toilet manufacturer’s guidance for winterizing your RV plumbing.
Do all four toilets have adjustable foot-pedal flushing?
No. Adjustable water flow is specified for the SEAFLO and Voyager Plus. The AW is described as having a foot-pedal flush, but adjustable flow is not stated in the supplied details. The Dometic’s flush-control style is not specified there either.
Are RV toilet heights measured the same way?
Product descriptions can use terms such as “chair height,” “residential height,” or “high profile,” so compare the listed measurements when available. The supplied heights are 18 inches for the Dometic, 19 inches for the SEAFLO, and 20 inches for the AW. Check the Voyager Plus listing for its exact measurement before buying.
Does an elongated bowl guarantee a comfortable fit?
No. Bowl shape is only one part of fit. Seat height, bathroom clearance, mounting position, and the needs of the people using the toilet all matter. Measure your space and compare the listed dimensions before choosing.
Final Recommendation
For most shoppers seeking a true elongated porcelain RV toilet, the SEAFLO is the strongest all-around choice in this group because it combines a porcelain bowl, 19-inch height, adjustable foot-pedal flush, and a listed four-year limited warranty. Choose the Dometic if its compact rear profile and two-bolt mounting design suit your replacement needs, or the Voyager Plus if its specified cold-weather valve is useful for your trips. The AW is a reasonable alternative for taller seating, but its HDPE body and enamel-coated interior make it a different choice from a true porcelain-bowl model. Whichever you choose, verify your measurements before ordering.
