SEAFLO RV Toilet Review (2026): Models, Problems & Verdict

Most RV toilet reviews only cover Dometic and Thetford, which makes sense since they’ve owned the category for decades. SEAFLO says its toilets are also used as factory equipment in RVs from Forest River, Jayco, Dutchmen, and Winnebago, according to SEAFLO’s own Amazon listing. That’s a claim worth checking, not just repeating, so this review digs into the actual specs, the rough-in numbers, and what real owners report.

This review breaks down what SEAFLO actually offers, which rough-in each model needs, and where the manufacturer’s specs and the retailer’s own listings disagree with each other. If you’re still comparing porcelain options, our porcelain RV toilet comparison covers the higher-end field side by side.

Quick Verdict Best for: Budget replacements, tight bathrooms under 9.5 inches of rough-in, first-time DIY swaps Skip if: You want the longest track record, a bidet-friendly seat, or a single confirmed rough-in number across every retailer Main risk: One documented flush-ball tab failure on the ceramic model; unclear how common it is Verdict: Solid budget pick in plastic. The ceramic model needs a closer look at price before you assume it’s the cheaper option.

How We Evaluated This Toilet

This is a research-based review, not a long-term hands-on test. We compared SEAFLO’s official specifications, current retailer listings, replacement-parts availability, verified purchaser feedback, and RV forum reports. Because several SEAFLO variants use different model numbers and rough-in measurements, and because retailer listings sometimes conflict with each other, every fit recommendation below is tied to the exact SKU wherever we could confirm one.

What Is the SEAFLO RV Toilet Best For?

The SEAFLO RV toilet is best for owners who want a residential-height, elongated bowl without paying full Dometic or Thetford prices for the plastic model. SEAFLO’s own listings put its plastic model as low as $169.99, well under a comparable Dometic or Thetford elongated toilet, according to SEAFLO Direct’s toilet catalog.

SEAFLO also says its toilets are factory-installed by Forest River, Jayco, Dutchmen, KZ, Grand Design, Brinkley RV, and Winnebago, per its Amazon product page. That’s SEAFLO’s own marketing claim rather than something we independently verified, but if your RV already shipped with a SEAFLO toilet, replacing it with another SEAFLO is usually the simplest swap you can make.

Skip it if you want the single most tested toilet on the market, or if you need every spec to match cleanly across every retailer. Dometic and Thetford have decades of field data behind them. SEAFLO is newer to the RV side of the business, and its own retail listings don’t always agree on basic measurements like rough-in.

Which SEAFLO Model Should You Buy?

SEAFLO sells at least five different RV toilet variants, and picking the wrong one is the easiest way to end up with a fit problem. Here’s how we’d sort them by use case.

SEAFLO RV Toilet Specs and Key Features

SEAFLO sells RV toilets under several model numbers, and the bowl material changes what the toilet is actually built from. The ceramic model combines a porcelain bowl with a polypropylene base. The lighter plastic model uses polypropylene for both the bowl and the base, according to SEAFLO’s own product specifications on Amazon.

Both versions use tri-directional flush nozzles meant to rinse the whole bowl instead of just the back wall. If you’re not sure which SKU your RV shipped with, our RV toilet parts guide walks through how to find your model number before you order replacement seals or a whole new unit.

Which Rough-In Does the SEAFLO Fit?

SEAFLO’s rough-in requirement depends on the exact model, and two of the most common SKUs have conflicting numbers even within the same retailer’s own listings. The table below shows what we could confirm.

Retailer SKU	Manufacturer model	Sprayer	Main listed rough-in	Conflicting figure found
SE25MR	SFRTPH-01-02	Yes	9.5 inches	A separate etrailer support answer lists 8.5 inches with a 4-inch flange for the same toilet
SE92MR	SFRTCH-02-01	No	8.5 inches	A separate etrailer support answer lists 9 inches for the same toilet
SE32MR	Not confirmed	Yes	9.5 inches	None found
SE42MR	Not confirmed	Yes	10 inches	None found
SFRTPH-01-01	SFRTPH-01-01	No	9.5 inches	None found

eTrailer uses its own retailer product codes, which don’t always map cleanly to SEAFLO’s manufacturer model numbers. We’ve noted confirmed matches above and flagged where we couldn’t verify one.

Given those conflicts, treat any single published rough-in figure as a starting point, not a guarantee. If your bathroom is on the smaller side generally, our guide to toilets for small RV bathrooms rounds up every current short-rough-in option, SEAFLO included, and walks through how to measure correctly the first time.

Installation and Fit Checklist

Check every measurement before ordering your SEAFLO toilet.

1. 01

   Wall-to-flange-center rough-in. Use the exact SKU’s listed figure as a starting point only, given the conflicts noted above.

2. 02

   Total front-to-back depth. The ceramic SE92MR runs about 20.5 inches from flange to front lip; the plastic SE25MR runs about 17.9 inches. Confirm this clears any cabinet or shower door.

3. 03

   Door or shower clearance. Check both sides of the toilet against any adjacent wall or fixture.

4. 04

   Lid-open clearance. Make sure the lid can open fully without hitting a wall or shelf behind it.

5. 05

   Water-line position. Note whether your existing supply line connects from the side or the rear, since some owners needed an adapter or a shortened line.

6. 06

   Floor flange size. One SEAFLO model uses a 4-inch flange diameter, which is smaller than some older toilets. Measure your flange, not just the bolt spacing.

7. 07

   Raised platform or step height, if your bathroom has one behind the toilet.

8. 08

   Toilet weight for handling. The plastic model is light enough for a one-person install at around 13 lbs. The ceramic model weighs about 36.5 lbs, so plan for two people or a dolly.

How Does the SEAFLO Perform in Real Use?

Real owners generally describe the SEAFLO as an upgrade over the toilet it replaced, with strong flush coverage and an easy foot pedal. On etrailer’s customer reviews for the SE25MR, one buyer who replaced a Dometic 300 said the install took under ten minutes, and another who replaced a Thetford Bravura called it a great value for a full-timer.

The sprayer attachment brings a real tradeoff worth knowing about. On Walmart’s customer reviews for the standard-height sprayer model, one buyer reported no leaks and strong bowl flow, but flagged that the sprayer wand has enough pressure that frequent use fills the black tank faster than expected. If you’re boondocking and watching tank levels, that’s worth factoring in before you lean on the sprayer for daily cleaning.

On the ceramic side, etrailer reviews for the SE92MR skew positive, with owners describing solid construction and a noticeably stronger, fuller flush pattern than the round Thetford and Dometic units they replaced. A couple of reviewers needed a small plumbing adjustment, like an elbow fitting or a shortened water line, but described the fix as quick and cheap.

Is the SEAFLO Ceramic Toilet Reliable? What Do Owners Say?

Owner reports on the SEAFLO ceramic toilet lean positive overall, but there’s at least one documented reliability issue worth knowing before you buy. An iRV2 forum thread describes a SEAFLO toilet that failed after five months, when two small plastic tabs connecting the flush ball to the flush lever snapped off. The same poster mentioned hearing of the same failure on other new RVs using the same brand toilet, though that’s a secondhand mention, not a separate documented case. That’s worth knowing, but there isn’t yet enough public owner data to say how common the failure actually is.

That thread also highlights a real headache with the warranty process. The RV dealer initially said the owner hadn’t followed the correct claims procedure, and the case had to be escalated to the RV manufacturer instead of resolved directly with SEAFLO. If you do have a warranty issue, document everything and go through SEAFLO’s official warranty page from the start.

Elsewhere, the picture looks better. In a separate iRV2 thread from an owner considering the ceramic SFRTCH-02-01 as a Thetford replacement, another forum member who’d already made the switch said the SEAFLO “was considered a major improvement over the previous Thetford,” with full bowl coverage on city water pressure. If your main concern is whether the flush ball can maintain a water seal over time, our guide to RV toilets not holding water covers what typically fails on any brand and how to check it.

Are SEAFLO Replacement Parts Easy to Find?

For the plastic models, yes. SEAFLO sells a full set of official replacement kits covering the parts most likely to wear out, according to listings on SEAFLO Direct and Amazon.

Part	Official kit	Compatible models
Ball valve seal	SFTRK-010	SFRTPH-01-01, SFRTPH-01-02, SFRTPH-02-01
Pedal flush mechanism	SFTRK-007	Same plastic models listed above
Water inlet valve	SFTRK-003	Same plastic models listed above
Water outlet valve	SFTRK-004	Same plastic models listed above
Flange gasket seal	SFTRK-005	Same plastic models listed above
Combined inlet and outlet kit	SFTRK-015	Same plastic models listed above

Every official parts listing we found names the plastic SFRTPH series specifically. None of the current listings confirm compatibility with the ceramic SFRTCH-02-01, including the flush ball assembly involved in the iRV2 failure report above. If you buy the ceramic model, that’s a real gap to be aware of, not just a minor detail. Our RV toilet parts guide covers how to track down a model number and cross-reference parts if you run into this.

SEAFLO Plastic: Pros and Cons

Pros: Genuinely budget priced at $169.99, light enough for a one-person install at about 13 lbs, backed by a full set of official replacement kits, and a 4-year warranty that beats most competitors.

Cons: Rough-in figures vary by exact SKU and sometimes conflict within the same retailer’s own listings, and the sprayer attachment can add real water use to your black tank if you use it often.

SEAFLO Ceramic: Pros and Cons

Pros: Elongated, residential-height porcelain bowl, owners consistently report a stronger and fuller flush than the round toilets it usually replaces, and it carries the same 4-year warranty as the plastic line.

Cons: At roughly $310 to $380 depending on retailer, it isn’t clearly cheaper than a Dometic 410 anymore. At about 36.5 lbs it needs two people or a dolly to install safely, replacement parts compatibility isn’t confirmed, and there’s at least one documented flush-ball tab failure to weigh against the mostly positive owner reports.

Should You Buy SEAFLO Instead of a Dometic or Thetford?

Buy the SEAFLO plastic model if budget and weight are your main constraints. Buy the SEAFLO ceramic model only after comparing its current price against a Dometic 410, since the two can land in the same range depending on the retailer. Buy Dometic or Thetford if you want the shortest confirmed rough-in or the most field-tested option.

Dometic’s 410 still wins on rough-in flexibility at 7.625 inches, which is shorter than any confirmed SEAFLO figure above. If your bathroom can take that shorter rough-in, it’s worth comparing current prices directly rather than assuming SEAFLO’s ceramic model is the cheaper option. For a full side-by-side of every current porcelain option, see our porcelain RV toilet comparison, and if plastic-bowl models are also on your list, our Dometic 400 review covers Dometic’s lighter-weight option at the same short rough-in.

Conclusion

SEAFLO isn’t trying to be a luxury toilet, and the plastic model doesn’t need to be. It’s a genuinely budget-friendly, residential-height option backed by a 4-year warranty and a full set of official replacement parts. The ceramic model is a different story: it’s a solid, comfortable upgrade, but it’s priced close enough to a Dometic 410 that the decision comes down to fit and parts availability, not just price.

Measure your rough-in, flange size, and water-line position first, and don’t assume one published number applies to every SEAFLO SKU. If the numbers line up and you’re leaning toward the plastic model, check the current price of the SEAFLO RV toilet on Amazon before you order, and keep your receipt handy in case you need the warranty.
