Delivers a luxury residential bathroom experience in a compact RV footprint.

Flagship of the 400 Series

The 420 Platinum is the premium tier of the Dometic 400 Series. If you're comparing series options:

• 420 Platinum (this listing) — Premium porcelain bowl, 19" elongated seat, 360° Powerflush, residential feel
• 400 Standard Height — Essential series high-profile plastic toilet
• 401 Low Profile — Essential series low-profile plastic toilet

Buyers wanting the closest thing to a residential home bathroom experience should choose the 420 Platinum.

Premium Elongated Porcelain Bowl

• Premium porcelain construction — not plastic
• High-gloss, scratch-resistant surface
• High-caliber stain and odor resistance
• Spacious 19-inch elongated seat length — the only 400 Series model at this size

360° Powerflush System

Delivers a full-coverage, rimless vortex rinse that scrubs the bowl clean using minimal water per flush. Cleaner bowl, less freshwater use — meaningful for RV holding tank management.

Standard 18" Chair Height

18-inch chair height for maximum comfort during long-term travel or full-time RV living. Same height as most residential toilets — no awkward crouch.

Space-Saving Compact Rear Footprint

The signature compact rear profile combined with a minimized 7-5/8" rough-in distance frees up valuable floor space — fits into tight RV bathroom layouts where standard elongated residential toilets can't go.

Hygienic Dual-Action Foot Pedal

• Partial press — adds water to the bowl
• Full press — initiates a powerful gravity flush

Foot operation keeps hands free of bathroom hardware.

Soft-Close Residential Seat

Easy-clean polypropylene seat with quiet-close, position-lock hinge — eliminates slamming. Same soft-close feel as premium residential toilets.

Heavy-Duty Structural Longevity

• Front-load tested to 2x weight capacity of leading competitors
• Bench-tested for 10,000+ flushes maintenance-free

Isolated Odor Control

Integrated sealed gravity valve design works alongside a one-way valve to isolate holding tank odors — keeping your mobile living area fresh and welcoming.

Universal 2-bolt mount for straightforward replacement of:

• Older Dometic 300 or 400 Series toilets
• Standard competitor models
• Rough-in requirement: 7-5/8" or greater

Drop-in swap with no plumbing layout modification required.
