Niagara Liberty 1.28 GPF Two-Piece Elongated Toilet
Niagara Liberty 1.28 GPF Two-Piece Elongated Toilet Review
The Niagara Liberty positioning
The Liberty (UPC C11.101.01, model N2840) is Niagara's value-tier 1.28 GPF toilet — the SKU for buyers who want Niagara brand pedigree but don't need (or can't reliably use) the Stealth line's ultra-low-flow 0.8 GPF flushing. At $170-$230, the Liberty competes directly with Kohler Highline Classic ($170-$280), American Standard Mainstream ($150-$210), and Mansfield Pro-Fit ($150-$220) in the value-tier mainstream toilet segment.
The Liberty is the right Niagara choice when: (a) the home has older drain lines where 0.8 GPF Stealth might not have enough flush momentum, (b) the rebate amount difference (typically $40-$80 less for 1.28 GPF vs ultra-low-flow) doesn't justify the Stealth premium, (c) the buyer wants simpler service (standard flapper vs Stealth-proprietary), or (d) the buyer wants a Niagara toilet at the lowest-cost-of-entry.
Why Liberty exists in the Niagara lineup
Niagara built the Stealth ultra-low-flow line as the brand's defining product. The Liberty exists because not every home is a good candidate for 0.8 GPF flushing — and the brand needed a value-tier WaterSense toilet for the broader market. Specifically:
- Older homes (pre-1980s) with cast-iron or galvanized drain lines — partial obstructions need flush volume to clear. 1.28 GPF has more momentum than 0.8 GPF.
- Heavy paper-use households — Liberty's 1.28 GPF flush handles paper loads that 0.8 GPF Stealth would double-flush.
- Buyers who don't qualify for ultra-low-flow rebates — Liberty still qualifies for standard WaterSense rebates ($40-$100 typical).
- Universal-parts preference — Liberty uses standard 3-inch flapper (Korky 2032BP fits) vs Stealth's proprietary parts.
Liberty vs Stealth Sabre — the Niagara decision
| Spec | Liberty N2840 | Stealth Sabre N7717 |
|---|---|---|
| GPF | 1.28 | 0.8 |
| Flush mechanism | Standard gravity, 3-inch valve | Vacuum-assist trapway |
| MaP | 800g | 800g |
| WaterSense Most Efficient | No (standard WaterSense) | Yes |
| Rebate amount (CA/AZ/TX typical) | $40-$100 | $75-$200 |
| Universal aftermarket parts | Yes (Korky 2032BP fits) | No (Niagara-proprietary) |
| Older home drain compatibility | Better — more flush momentum | Marginal — may need clear drains |
| Price (~) | $170-$230 | $280-$340 |
| Best for | Older homes, heavy paper use, simpler service preference | Modern drain lines, maximum rebate, water-savings priority |
The Liberty's value proposition: same WaterSense compliance + Niagara brand + 25-year service life at $110+ less than Stealth Sabre, with the trade-off of higher water use and lower rebate.

What owners report
- Reliable for normal household use. MaP 800g delivers solid waste-clearance.
- Universal parts service is the convenience advantage over Stealth — owners replace flappers at Home Depot rather than ordering from Niagara direct.
- Standard ceramic glaze shows hard-water spots — same trade-off as other value-tier toilets.
- The Comfort Height + elongated combination is the buying logic for adult-focused bathrooms.
- Service life: 20-25 years porcelain.
- Less retail visibility than Cadet 3 or Cimarron — Liberty often special-order at some retailers.
The verdict
Buy Liberty if:
- Older home with cast-iron or partial-obstruction drain lines
- Heavy paper-use household where 0.8 GPF Stealth would frequently double-flush
- You want Niagara brand at value-tier price with universal aftermarket parts
- Budget under $230 ceiling and standard WaterSense rebate is acceptable
Skip and choose Stealth Sabre if:
- You're in CA/AZ/TX with WaterSense Most Efficient rebate eligibility
- Water conservation is the priority + you have modern drain lines
- $100-$130 premium for ultra-low-flow + higher rebate is justifiable
Skip and choose Kohler Cimarron or AmStd Cadet 3 if:
- Brand recognition matters more than Niagara's water-savings reputation
- Broader retail availability is preferred
Warranty
Niagara Liberty warranty: 5 years on tank trim, lifetime on porcelain. Same brand warranty terms as Stealth line. Universal aftermarket parts widely available.
