Score: 72/100Rankings

The Brondell SMB-15 is a side-mounted, non-electric bidet attachment featuring an all-metal zinc-plated brass construction and a plastic-free design for enhanced durability. It offers adjustable water pressure and a swing-action oscillating spray wand with seven nozzles for wide cleansing coverage. However, it lacks heated water options and automated features.
The Mayfair Cassel Bidet Bundle combines a round, enameled-wood toilet seat with a non-electric, fresh-water bidet attachment. It features a slow-close mechanism and a top-tightening fastening system designed for stability and quiet operation without requiring electrical installation. It is best suited for homeowners or renters who want to add a bidet without running electricity and prioritize hygiene and comfort over high-tech heated features.
