Battle of the Toilets: Which Toilet is Better?


You don’t have to scan a lot of forums and discussions on Reddit. This part is about American Standard Champion 5 vs Kohler Cimarron so you can evaluate each product and then select the one that suits you.

1. Clogging and leaking issues

Both Champion 5 and Cimarron have innovative, powerful flushing systems. Since Champion has the ability to get rid of 70% more waste than the regular toilet, there’s no doubt that it won’t be easily clogged. On the other hand, Cimarron can inhibit leakage due to its DryLock installation.

2. Water consumption

Water conservation is a concern of many so this is a basis when buying a toilet. Both of these toilets are recognized by WaterSense, which means that they’re water-saving toilets. Although Champion 4 requires 1.6 gallons per flush and Cimarron only 1.28 gallons per flush, the difference is minimal. You won’t sometimes need to flush twice in special cases with Champion 4 because it can eliminate greater mass.

3. Flushing system

The flushing systems of these toilets work with gravity but the operation differs. In the case of Champion 4, there’s a 4-inch piston flush valve that works with a siphonic jet for a powerful flush. The water goes to the rim with a lot of pressure so it can push 70% of the mass down the pipe. Interestingly, it works quietly even with such power while not giving clogging a chance to bother you.

Cimarron flushes with a canister flush valve and Aquapiston technology. This combination shoots water to clean the bowl properly. Clogging won’t be an issue while you save water from daily use.

4. Warranty and cost

The warranty for Champion 4 is for 10 years while it’s only a year for Cimarron. In terms of cost, Champion is favorable since it’s only for around $500 while Cimarron is sold at $700. The money that you can save from 1.28 GPF of Cimarron may compensate for its higher price. Furthermore, you have to buy the seat and supply it separately for Cimarron. So, prepare for this extra cost.

The Final Words

In comparing Kohler Cimarron vs American Standard Champion 4, flushing system, water consumption, bowl height, durability, and aesthetics are valued. They both excel in some features. If the users are after a lower amount of water for every flush, Kohler Cimarron is fine. It’s guaranteed that it can save tons of water. Champion 4 is for those who usually take heavy dumps so a single flush is necessary.
