The best elongated porcelain RV toilet depends on your bathroom’s mounting dimensions, preferred seat height, and desired features. The SEAFLO SFRTCH-02-01 is best for a 19-inch seat height and simple foot-pedal flushing; its sprayer-equipped version adds a handheld rinse option. The Dometic Model 420 is a strong replacement candidate for compatible standard RV rough-ins, while Lippert offers an 18-inch ceramic option. Check measurements and flange compatibility before choosing.

SEAFLO SFRTCH-02-01 Porcelain RV Toilet
Best for: RV owners seeking an elongated porcelain bowl with a 19-inch residential-style height and straightforward foot-pedal operation. This model uses a gravity flush with adjustable water flow and has a lightweight plastic base beneath its ceramic bowl.
The non-porous porcelain surface is described as resistant to staining, odor retention, and buildup, making it easier to clean than plastic bowl alternatives. A soft-close seat is included, and the listed dimensions are 20.51 by 14.17 by 19 inches. Its stated four-year limited warranty is another distinguishing feature.
Limitation: It does not list a handheld sprayer. Confirm the available bathroom space and installation dimensions before ordering.
SEAFLO SFRTCH-02-02 With Sprayer
Best for: RV users who want the SEAFLO 19-inch format and a handheld sprayer attachment. The package includes a wall mount for the sprayer, while the toilet itself has an elongated porcelain bowl, plastic base, gravity flush, adjustable water flow, and foot-pedal operation.
Its listed dimensions are 20.51 by 14.17 by 19 inches, and the seat is described as soft-close. Like the other SEAFLO model, its porcelain bowl is described as non-porous and resistant to stains, odor retention, and buildup. The product listing specifies a four-year warranty.
Limitation: The sprayer adds an accessory to plan for in the bathroom layout. Verify that the included mounting location and available space suit your installation.
Dometic Model 420 Platinum RV Toilet
Best for: Buyers considering a replacement toilet who need an elongated porcelain bowl and a 2-bolt mounting system. Dometic lists a universal mount and says the shared footprint fits standard RV rough-ins of 7.625 inches or greater. The porcelain surface is described as scratch-resistant and resistant to stains and odors.
The product information also highlights a 19-inch seat-length porcelain bowl and a soft-close seat. Its replacement-focused design may be useful when upgrading without changing the bathroom layout, but fit still depends on the existing rough-in and mounting arrangement.
Limitation: The listing specifies rough-in and mounting criteria, not universal compatibility with every RV. Measure the installation and verify the existing bolt configuration before selecting it.
AW High-Profile RV Toilet
Best for: Taller users or buyers who prefer a higher sitting position. This toilet is listed as 20 inches high and uses a foot-pedal gravity flush with an elongated, soft-close seat. Its body is made from HDPE, and the inner surface has a porcelain-enamel coating intended to resist rust and scratches.
The smooth, ceramic-like coated surface is described as resisting stains and buildup. This can suit RVs, trailers, campers, and motorhomes where a taller profile is preferred over a standard-height model.
Limitation: The listing calls for 6 11/16-inch flange bolt spacing and less than 1/2-inch protrusion above the floor. Check those measurements carefully; this is an enamel-coated surface, not a solid porcelain bowl.
Lippert Flow Max Ceramic RV Toilet
Best for: Buyers who want an 18-inch standard-profile height and a full-size residential seat. The Flow Max has a 100% ceramic bowl, an easy-close seat and lid, and a foot pedal for hands-free flushing. Pressing the pedal halfway adds water to the bowl; pressing it fully flushes.
The 18-inch height may be a better fit than a 19- or 20-inch model for households seeking a lower seat profile. Its ceramic construction distinguishes it from toilets with plastic bases or coated interiors.
Limitation: The product details provided do not specify mounting dimensions or rough-in compatibility. Check those details for your RV before purchasing.
Buying Guide: How to Choose an Elongated RV Toilet
Will the toilet fit your RV?
Measure the existing toilet, floor flange, bolt spacing, and clearance to nearby walls or cabinets. Do not assume that “universal” means it fits every RV. The Dometic listing specifies a standard rough-in of 7.625 inches or greater, while the AW listing calls for 6 11/16-inch bolt spacing and a specific flange protrusion limit. Compare your measurements with the product’s installation requirements.
Which bowl and surface should you choose?
Solid porcelain or ceramic bowls provide the hard, smooth surface described for the SEAFLO, Dometic, and Lippert models. The AW toilet instead uses an HDPE body with a porcelain-enamel inner coating. If material is a priority, distinguish a ceramic bowl from an enamel-coated interior when comparing options.
What seat height is most comfortable?
The listed heights range from 18 inches for the Lippert to 19 inches for the SEAFLO models and 20 inches for the AW. A taller seat may suit people who prefer easier sitting and standing, while a lower profile may work better for other users or limited bathroom space. Check whether the listed height refers to the seat or toilet profile when confirming fit.
Do you need a sprayer or a particular flush control?
All five selections use foot-pedal operation or gravity flushing as described in their product details. The SEAFLO SFRTCH-02-02 is the option that specifically includes a handheld sprayer and wall mount. Consider accessory placement and installation needs alongside the toilet’s flush operation.
