Choosing the Right Toilet: A Buyer's Guide

Replacing a toilet is a bigger decision than it might seem. The right fixture affects daily comfort, water consumption, and how your bathroom looks and functions for years. With a wide range of models available across brands like American Standard and Kohler, knowing which features actually matter helps you narrow the field quickly.

Start With Your Bathroom's Constraints

Before looking at specific models, assess the basics. Measure the rough-in distance—the gap from the finished wall to the center of the drain bolts. Most toilets are built for a 12-inch rough-in, but 10-inch and 14-inch versions exist for older homes. Also consider the available floor space: an elongated bowl offers more seating comfort but extends about two inches farther from the wall than a round bowl, which can matter in a tight bathroom.

Flushing Performance

The flush mechanism is the most important functional consideration. American Standard's PowerFlush and Kohler's AquaPiston are both well-regarded systems designed to clear waste completely in a single flush. Look for MaP (Maximum Performance) test scores when comparing models—a score of 800 or above means the toilet reliably removes solid waste in one flush. Poor flushing performance leads to double-flushing, which wastes water and defeats the purpose of a water-efficient model.

Water Efficiency

EPA WaterSense-certified toilets use no more than 1.28 gallons per flush (GPF), compared to older 3.5 to 6 GPF models. Over the life of the fixture, the savings are significant. Dual-flush models offer two options—a lower volume for liquid waste and full volume for solid waste—giving households more control over daily water use. Both American Standard and Kohler offer WaterSense-certified options across their product lines.

Height: Standard vs. Comfort Height

Standard toilets measure 15–17 inches from floor to seat. Comfort height models sit at 17–19 inches—roughly the height of a standard chair—and are easier to use for taller adults, seniors, or anyone with limited mobility. Kohler labels these as "Comfort Height" models; American Standard calls them "Right Height." Neither style is universally better; the right choice depends on the primary users of the bathroom.

Build Quality and Durability

Both American Standard and Kohler make their toilet bowls and tanks from vitreous china, which resists staining, scratches, and fading. Look for smooth, seamless glazing on interior surfaces—it reduces the surface area where bacteria and mineral deposits can cling. Tank components (flappers, fill valves, flush handles) vary more between models; replacement parts for mainstream American Standard and Kohler lines are widely available and inexpensive, which matters when something eventually wears out.

Installation and Maintenance

Most two-piece toilets (separate tank and bowl) install with standard tools and follow a predictable process. One-piece models look cleaner and are easier to wipe down, but they're heavier and more expensive. Quick-release seat hinges make cleaning under the seat straightforward. If you're hiring a plumber to install, the labor cost is roughly the same regardless of model—so spend the difference on a better fixture rather than trying to save on parts.

Budget Considerations

Entry-level toilets from both brands start around $150–$250 and offer reliable performance. Mid-range models in the $300–$600 range add features like stronger flushing, better bowl glazing, and more refined aesthetics. High-end models above that price point often include integrated bidet functions, heated seats, or auto-open lids—useful features, but not necessary for most households. The sweet spot for most bathrooms is a mid-range model with a strong MaP score, WaterSense certification, and parts that are easy to source locally.
