Dometic Sealand RV Toilet | 510H | High Profile | White | 2-Bolt

Bring residential comfort to your RV bathroom with the Dometic Sealand 510H 2-Bolt Gravity Discharge Toilet (Part #302510001) in white. This high-profile traveler toilet combines maximum flush performance with minimal water usage — featuring a powerful rim wash with the best bowl coverage in its class, an elongated wood seat, deeper bowl, and increased seat height for a genuinely household-feel experience. The right RV toilet upgrade for buyers who want home-like comfort and refined performance without sacrificing RV-appropriate water conservation.

Why the Sealand 500 Series Stands Out

The Dometic Sealand 500 series is designed to deliver the comforts of a household toilet with the practical demands of RV use:

• Ultra-low water consumption — less than one pint (0.10 gal / 0.39 L) per flush, dramatically extending fresh and black water tank capacity
• Trouble-free performance across years of use
• Hands-free pedal flushing — no buttons, no levers, just step
• Household-sized seat for maximum comfort compared to prior RV toilet designs
• Eco-friendly water conservation without performance compromise

Maximum Flush Performance, Minimal Water Use

The 510H achieves a meaningful balance most RV toilets struggle with:

• Powerful rim wash delivers the best bowl coverage in its class
• Less than 1 pint per flush water consumption
• Deeper bowl design reduces splashing and contains waste more effectively
• Improved rim wash over earlier Sealand models

That combination of low water use and strong flush performance is genuinely meaningful for boondocking and extended travel — your tank capacity goes much further without sacrificing cleanliness.

Tall / High-Profile Design — Residential Seat Height

The 510H is the tall (high-profile) variant in the 510 series — meaningful for comfort:

• 17.25" seat height — closer to residential toilets than typical RV units
• 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 pedal flush operation is one of the standout daily-use features:

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

Comfort Features Borrowed from Home

Design touches that elevate the 510H above basic RV toilets:

• Elongated enameled wood seat — household-style comfort and durability
• Residential-style deep bowl for enhanced comfort and cleanliness
• Household-sized seat compared to prior RV toilet generations
• Standard 19.25" height × 15" width × 21.5" depth profile

Proven Marine and RV Heritage

The Sealand 500 series gravity-discharge architecture has been proven in thousands of marine applications — meaning the underlying mechanism is engineered for the constant motion, vibration, and demanding usage conditions of boat and RV environments. That track record is meaningful for a toilet you'll depend on daily.

Safety: Integral Vacuum Breaker

The 510H includes an integral vacuum breaker — a safety device that protects your RV's freshwater supply from potential cross-contamination via the toilet supply line. Important plumbing safety credential built right into the toilet.

2-Bolt Floor Flange Mounting

Important installation note: The 510H uses a 2-bolt floor flange pattern. If your existing RV toilet uses a different mounting pattern (3-bolt, 4-bolt, or other), you may need to adapt the floor flange before installing this toilet. Verify your existing floor flange pattern before ordering — improper mounting can cause leaks, instability, or installation failures.

Have a 4-Bolt Floor Flange? See the 510+

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

Freight Shipping Included

This toilet ships FREE via private logistics/freight due to its size and weight. Important shipping notes:

• Freight delivery — schedule arrangement with the freight carrier
• Residential delivery and lift gate service may be available — request when the carrier calls to arrange delivery
• Freight items cannot be returned — confirm fitment, dimensions, and floor flange pattern before ordering

Without Hand Sprayer Variant

This specific listing is the 510H without hand sprayer. If you want a model that includes a hand sprayer for additional bowl cleaning capability, see the Sealand variants with hand sprayer included (when available in catalog).

Replacement Seat Available

When your toilet's seat eventually needs replacement, the matching Sealand seat for the 500+ series is the Dometic Sealand 500+ White Toilet Seat Assembly (Part #385343829) — fits the 510H along with other Sealand Vacuflush and Traveler models.
