Dometic Sealand 510+ China RV Toilet | 302651001 | 4-Bolt | White

Bring residential comfort to your RV bathroom with the Dometic Sealand 510+ 4-Bolt Gravity Discharge Toilet (Part #302651001) in white china porcelain. This high-profile Traveler toilet — also written as "510 Plus" or "510PS" — combines maximum flush performance with household-style comfort. Featuring an improved rim wash, deeper bowl, increased seat height, and household-sized seat for genuinely home-like comfort. The right RV toilet upgrade for buyers with a 4-bolt floor flange installation.

⚠️ 4-Bolt Floor Flange Pattern

The 510+ uses a 4-bolt floor flange pattern. This is the most critical fitment detail to verify before ordering. Three common scenarios:

• Existing 4-bolt flange: The 510+ is a direct drop-in match — verify floor flange has 4 bolts
• Existing 2-bolt Sealand flange: The 510+ is NOT compatible — see the Dometic Sealand 510H (2-Bolt) instead
• Replacing a Thetford toilet with 2-bolt flange: You can use the 510+ but will need a 2-to-4 bolt flange adapter (sold separately)

Verify your existing floor flange pattern (count the bolts) before ordering — improper mounting can cause leaks, instability, or installation failures.

Why the Sealand 500+ Series Stands Out

The Sealand 500+ series brings genuinely residential comfort to RV bathrooms:

• Improved rim wash over earlier Sealand models — better bowl coverage with each flush
• Deeper bowl design reduces splashing and contains waste more effectively
• Increased seat height (17-1/4") — closer to residential toilet standards
• Household-sized seat for maximum comfort compared to prior RV toilet generations
• Foot pedal flushing — hands-free, no electric power required
• Sturdy china porcelain construction — same material as residential toilets

Tall / High-Profile Design

The 510+ is the high-profile variant of the 510 series:

• 17-1/4" seat height — close to residential toilet standards
• Easier to sit down and stand up — particularly important for older travelers or those with mobility concerns
• More natural sitting position for taller users

Hands-Free Pedal Flushing

The foot pedal flush operation is one of the standout daily-use features:

• No electric power required — works in any conditions
• Hands-free hygiene — no buttons to touch
• Simple, reliable mechanism — fewer failure points than electric or vacuum systems

Premium China Porcelain Construction

The 510+ uses china porcelain construction — the same material as residential toilets:

• Easy to clean — smooth, non-porous surface
• Stain-resistant
• Durable for years of use
• Premium look and feel compared to plastic-shell RV toilets

Considering the 510H (2-Bolt) Instead?

If your installation uses a 2-bolt floor flange rather than 4-bolt, the matching Sealand 510 variant is the Dometic Sealand 510H Tall Gravity Discharge Toilet (2-Bolt). Same Sealand quality and household-style features, just different floor flange pattern. The 2-bolt and 4-bolt variants are NOT interchangeable without a flange adapter.

Replacing a Thetford? Flange Adapter Required

If you're replacing a Thetford toilet with a 2-bolt floor flange and want to install this 510+, you'll need a 2-to-4 bolt flange adapter (sold separately) to make the existing floor flange compatible with the 510+ mounting pattern. The adapter is the cleanest path to a Thetford-to-Sealand swap without major floor work.

Freight Shipping Included
