Thetford 42058 Aqua-Magic Style II RV Toilet, High Profile - Home

In this review of the Thetford 42058 Aqua-Magic Style II RV Toilet high profile model, the bottom line is simple: camper owners who want a real china bowl and residential seat height in an RV-friendly package will appreciate it most. The standout reason to choose this toilet is its combination of a full-size, comfortable 17 1/2' seat height and a vigorous flush that claims 100 percent bowl coverage, delivering a home-like experience without the weight penalty of traditional china bowls.

Key Features

• China bowl, lightweight: Delivers the smooth, easy-clean surface of china while being about 20 percent lighter than similar models for easier handling and installation.
• Powerful single-pedal flush: A convenient single-pedal operation produces a vigorous flush designed to cover the entire bowl for cleaner results.
• New flush valve design: The revolutionary ball valve mechanism wipes clean with every flush, reducing residue and maintenance effort.
• Full-size residential seat: A taller 17 1/2' seat height offers home-like comfort for longer trips and those who prefer a higher seating position.
• Easy replacement fit: Sized to replace most permanently installed RV toilets, making it a straightforward upgrade for many trailers and fifth wheels.

Who It's For

This toilet is best for RV owners who value a true china bowl and residential comfort in a mobile setting, particularly those replacing an older permanently installed toilet in a travel trailer, fifth wheel, or motorhome. It suits users who want an easy-to-use single-pedal flush and a taller seat without adding excessive weight.

It may be less suitable for buyers who prioritize the absolute lightest possible components for extreme weight saving or those who need specialized low-profile installations; the high profile model is 26 1/2 lbs and designed for a taller seat height.
