The under-$300 toilet market is the sweet spot for residential renovations — you get genuinely good toilets from major brands at prices that make sense for multi-bathroom households. The standouts: American Standard Cadet 3 FloWise ($269–$359, frequently under $300 on sale), Kohler Cimarron Comfort Height Two-Piece ($329–$429, $279–$299 during major retailer promotions), Niagara Phantom 1.6 GPF Two-Piece Elongated ($259–$329), Niagara Liberty Two-Piece Elongated ($199–$259).
American Standard Cadet 3 FloWise is the consensus best-pick at this price — comfort-height, elongated, 1.28 GPF, robust gravity-feed flush, EverClean glaze for longevity, broad US parts availability. The FloWise variant uses redesigned bowl geometry that maintains flush performance at lower GPF compared to legacy Cadet 3 models.
Kohler Cimarron is the most-recommended mid-tier toilet in the US, and at retailer sale pricing it falls under $300. The Cimarron line includes round-front, elongated, comfort-height, standard-height, and one-piece variants — pick the configuration that fits your bathroom and household needs.
For dual-flush at under $300, the Niagara Stealth ($279–$339) is the strongest pick — vacuum-assist 0.8/1.1 GPF dual-flush, EPA WaterSense certified, MaP score 800g+. The Niagara Liberty 1.28 GPF single-flush is the lower-cost alternative if dual-flush isn't a priority.
Delta Hatcher and Delta Foundations (both $249–$329) round out the at-this-price options — Delta toilets are sometimes overlooked but offer good value with lifetime ceramic warranties on the porcelain.
