Introducing the All-New Dometic 420 Platinum RV Toilet: The New Standard for RV Bathroom Comfort

For years, RV owners have had to choose between comfort and space when upgrading their bathroom. Larger residential-style toilets often required additional room, while compact RV toilets sacrificed comfort and convenience.

The new Dometic 420 Platinum changes that.

As the flagship model in Dometic's all-new 400 Series, the 420 Platinum combines a full-size elongated porcelain bowl, residential-style comfort, and industry-leading space-saving design into one premium RV toilet. Designed to fit where many other elongated porcelain toilets cannot, the 420 Platinum delivers a true at-home bathroom experience without requiring additional floor space.

What Makes the Dometic 420 Platinum Different?

The Dometic 420 Platinum was engineered from the ground up to solve some of the most common complaints RV owners have about traditional RV toilets.

Full Residential-Style Comfort

Unlike most RV toilets that use a compact round bowl, the 420 Platinum features a full-size elongated porcelain bowl with a 19-inch seat length and an 18-inch chair-height design. The result is a seating position that feels much more like a home bathroom.

Premium Porcelain Construction

The elongated porcelain bowl provides a durable, scratch-resistant surface that resists stains and odors better than traditional plastic RV toilets. The non-porous finish is easier to clean and helps maintain a fresh bathroom environment.

Fits Where Other Elongated Toilets Won't

One of the most impressive features of the 420 Platinum is its compact rear profile and industry-short rough-in requirement of just 7.625 inches. This innovative design allows RV owners to install a luxury elongated toilet in spaces where many competing porcelain models simply will not fit.

Powerful and Efficient 360° Powerflush Technology

The Dometic 420 Platinum features Dometic's new 360° Powerflush system, designed to provide complete bowl coverage while using minimal water.

Benefits include:

• Cleaner bowl after every flush
• Quieter operation
• Improved rinse performance
• Reduced water usage
• Better overall sanitation

Combined with the gravity-flush design and integrated odor-control sealing system, the 420 Platinum delivers reliable performance whether you're camping for a weekend or living full-time on the road.

Easy Replacement for Existing RV Toilets

The 420 Platinum was designed to simplify upgrades.

Features include:

• Universal 2-bolt mounting pattern
• Fits rough-ins of 7.625 inches or greater
• Compatible with many existing RV toilet installations
• Simple drop-in replacement design

Whether you're replacing an older Dometic toilet, a Thetford model, or upgrading from a plastic toilet, installation is straightforward in most RV applications.

Designed for Long-Term Reliability

Dometic focused heavily on durability when developing the 420 Platinum.

Highlights include:

• Heavy-duty glass-reinforced water valve
• Redesigned sealing system to prevent internal leakage
• Integrated one-way valve for improved hygiene
• Soft-close residential-style seat and lid
• Common service parts designed for DIY replacement
• Tool-free ball seal replacement

The toilet has also been tested to withstand twice the front-load weight capacity of many competing models and has undergone extensive flush-cycle testing to ensure long-term reliability.
