Detailed Comparison
Niagara internal: One ($380-440, one-piece, 1.0 GPF) vs Liberty ($180-220, two-piece, 1.28 GPF). Same brand, very different form factors and water-use targets. The One features a one-piece silhouette, lower 1.0 GPF rating, and Niagara's premium glazing. The Liberty is the workhorse two-piece value pick at the same brand. For homeowners optimizing for water conservation as a top priority, the One pays back over time. For value-first buyers, the Liberty delivers the brand's engineering at half the cost.
Final Verdict
We recommend the Niagara One for buyers prioritizing water savings — 1.0 GPF saves 2,000+ gallons per year over the Liberty's 1.28 GPF. Choose the Liberty for the simpler two-piece form and lower upfront cost.
