Dometic MasterFlush 8746 Macerating RV Toilet
The Dometic MasterFlush 8746 is a premium macerating toilet built for motorhomes, fifth wheels, and marine vessels requiring residential-style comfort with reliable waste management. The ceramic bowl and elongated enameled wood seat with slow-close mechanism deliver the upscale appearance and ergonomic comfort of a home bathroom. The high-performance macerator pump operates 30% more efficiently than previous Dometic macerator models, grinding waste before pumping it to the holding tank while maintaining ultra-quiet operation thanks to an integral water trap that reduces macerator sound.
The 12-volt DC electrical system powers the macerator and electronic flush handle. Dual flush options—normal flush and dry bowl mode—allow operators to conserve water without sacrificing performance. Through-the-floor and through-the-wall discharge fittings provide flexible plumbing installation compared to traditional gravity toilets, improving waste evacuation and enabling more innovative RV and marine layouts.
