        "content": "If you\u2019ve got a 1.6-gallon elongated toilet (single flush) that\u2019s good, but still struggle with hard stools sometimes, there *are* several other toilets and brands that offer stronger flushes, better bowl designs, and more effective waste removal\u2014without jumping to commercial or 3+ gallon models.\n\nHere\u2019s what to look for, plus some top alternatives that match your criteria.\n\n---\n\n## Key Features That Improve Flushing Power\n\nTo get rid of tough, hard stools in a single flush, you want these features:\n\n- **Large flush valve** (3\", 4\") or efficient valve design. More water rushes out faster.  \n- **Fully glazed trapway** and wide diameter. Smooth surfaces \u2192 less chance for waste to get stuck.  \n- **Powerful flushing mechanism**: Tornado Flush, Swirl / Revolution 360, ProForce, Tsunami / Centrifugal rinse, etc. These concentrate and direct the water better.  \n- **Siphon jet design** or strong siphonic bowl. Helps when large volumes need suction.  \n- **WaterSense or EPA certified** (if you want water savings). Even 1.6 GPF with a strong design can clear hard waste.  \n\n---\n\n## Top Alternatives to Your Current Toilet\n\nHere are several models/brands that people evaluate highly for strong waste removal. These are elongated bowls, about 1.6 GPF of water, or dual-flush models that perform nearly as well.\n\n| Toilet | Key Advantages | Notes |\n|---|---|---|\n| **American Standard Champion 4** | Often regarded as the strongest gravity model. Oversized 4-inch flush valve + extra-wide, glazed trapway. Clears large bulk with ease. ([bestflushingtoilets.com](https://bestflushingtoilets.com/toilets/best-toilet-for-heavy-waste/?utm_source=openai)) | Good option if you want powerful single flush performance. Likely louder. |\n| **TOTO Drake (1.6 GPF, Tornado Flush)** | Two high-powered nozzles send a centrifugal rinse, very reliable waste removal. Great value. ([kbauthority.com](https://www.kbauthority.com/news/toto-drake-1-6-gpf-elongated-two-piece-toilet-still-the-best-flush-for-the-money/?utm_source=openai)) | The glaze (CeFiONtect) helps prevent sticking and buildup. ([profindr.com](https://profindr.com/guides/listicle/best-toilet-brands-ranked?utm_source=openai)) |\n| **Kohler Santa Rosa (Revolution 360\u00ae swirl flush)** | Compact elongated, full-gravity design with swirl helps clean the bowl more thoroughly. ([la.kohler.com](https://la.kohler.com/en/product-detail/30811?skuid=K-30811-0&utm_source=openai)) | Great if bathroom space is a little tight but you still want an elongated bowl. |\n| **Hanikes AR354W** | Dual-flush (1.6/1.1 GPF), tornado flush with centrifugal rinse, MAP score of 1000g. Very capable. ([homedepot.com](https://www.homedepot.com/p/329058558?utm_source=openai)) | Dual flush gives water saving options, while still clearing solids in the full flush. |\n| **TOTO UltraMax One-Piece** | Single-flush 1.6 GPF with G-Max technology (gravity flush). Clean trapway and powerful flush action. ([manualshelf.com](https://www.manualshelf.com/manual/toto/ms854114sg-01/specification-sheet-english/page-1.html?utm_source=openai)) | One-piece design is easier to clean and may be more attractive aesthetically. |\n| **Kohler Sterling Windham** | ProForce Technology offering strong siphonic suction, fully glazed trapway, solid performance in one-flush cleanup. ([homedepot.com](https://www.homedepot.com/b/Bath-Toilets/Standard/Elongated/Single-Flush-16/N-5yc1vZbzbdZ1z0m20cZ1z0zbtkZ1z266g4?utm_source=openai)) | A good match if you want something solidly built and very reliable. |\n\n---\n\n## Things to Be Mindful Of\n\n- **Rough-in size**: Many US homes use a 12-inch rough-in; some models need 10- or 14-inch. Measure before buying.  \n- **Height**: Comfort (ADA or Universal) height toilets are slightly taller (17\u201319\") and easier if you have joint concerns.  \n- **Noise**: Pressure-assisted or large-valve gravity models tend to be louder. Gravity models like TOTO and Champion options are quieter.  \n- **Water restrictions**: Some states (esp. CA, CO, NY, TX, WA) require WaterSense certified units (1.28 GPF or dual flush). If you're in one of those states, you might want a high-performance 1.28 GPF or dual-flush toilet to stay compliant. ([consumerreports.org](https://www.consumerreports.org/home-garden/toilets/best-toilets-of-the-year-a5565220264/?msockid=23f01cb9ac976b97235f0a45adb26a82&utm_source=openai))  \n\n---\n\nIf you like, I can narrow this down by your price-range, what\u2019s available locally (in the US), and your existing rough-in or height preferences. Want me to pull together a shortlist based on that?"

If you want the *next best thing*, here are toilets and techs that are very close (or in some ways better) in performance, water efficiency, or both.\n\n---\n\n## What \u201cNext Best Thing\u201d Means\n\nHere are a few directions that compare favorably to or improve on your current setup:\n\n- Models with equal or lower water usage but just as effective (or more) flushing.\n- Dual-flush designs: full flush for solids, smaller flush for liquids.\n- Strong flush systems from other brands (different tech than Tornado) that deliver similarly good results.\n- Highly rated models in testing (MAP / lab tests / Consumer Reports).\n\n---\n\n## Strong Alternatives You Should Consider\n\nThese options come close to matching\u2014or beating\u2014your current toilet in flushing performance, while offering additional benefits like better efficiency or comfort.\n\n| Model / Brand | What Makes It Stand Out | Comparison to Your Current |\n|---------------|--------------------------|-----------------------------|\n| **TOTO Drake (1.6 GPF or 1.28 GPF with Tornado Flush)** | Powerful dual-nozzle Tornado Flush; excellent waste removal; still maintains strong performance at 1.28 GPF for WaterSense-compliant models. ([vatero.com](https://vatero.com/blogs/guides/toto-drake-vs-aquia-iv-tornado-flush-compared?utm_source=openai)) | Very similar in flushing power. If you go 1.28 GPF, you save water yet get nearly the same performance. |\n| **American Standard Champion 4 (Single-flush, 1.6 GPF)** | Oversized flush valve, very wide trapway; some of the best flushing among gravity toilets. ([homedepot.com](https://www.homedepot.com/b/Bath-Toilets/Chair-Height/Single-Flush-16/Less-than-1-GPF/N-5yc1vZbzbdZ1z0m208Z1z1r6ubZ1z266g4?utm_source=openai)) | Comparable power. Might be louder and uses the same water as yours. If lowered to less than 1.6, could save water. |\n| **Kohler Santa Rosa / Kohler Class Five Tech Models at ~1.28 GPF** | Modern swirling or Class Five flushing tech that clears waste well even at higher efficiency. Kohler has several models at 1.28 GPF with excellent performance. ([resources.kohler.com](https://resources.kohler.com/common/pdfs/watersensetoilets.pdf?utm_source=openai)) | Often similar in power but more efficient. If they hit the 1.28 GPF mark, you meet new WaterSense numbers. |\n| **Dual-Flush options** (1.6 / ~1.1 GPF) | Gives you solid-waste power when needed (1.6) and water savings for liquids (~1.1). Example: American Standard Clean Dual-Flush Elongated toilet with PowerWash\u00ae rim. ([lowes.com](https://www.lowes.com/pd/American-Standard-Clean-White-1-6-1-1-GPF-12-Rough-In-WaterSense-Elongated-Dual-Flush-2-Piece-Chair-Height-Toilet/50081926?utm_source=openai)) | More efficient overall; still powerful when used in full flush mode. Slight complexity: two buttons, may slight learning curve or cost. |\n\n---\n\n## Trade-offs to Think About\n\n- **Water usage**: Dropping from 1.6 to 1.28 GPF or using dual-flush can save water\u2014but ensure performance remains solid. Many newer models do meet that standard. ([epa.gov](https://www.epa.gov/watersense/residential-toilets?utm_source=openai))  \n- **Noise & feel**: Stronger flush systems (large valves, swirl or bowl-rim jets) tend to be louder and/or more forceful. If the toilet is next to a bedroom, this can matter.  \n- **Size / comfort**: Look at chair/ADA height\u2014some of these toilets are taller, which many people prefer. Also, bowl shape (elongated) is common, but trapway design (skirted vs. exposed) affects cleaning.  \n- **Availability & parts**: Some high-end or specialty models may be harder to find, more expensive, or have tougher-to-source parts.  \n\n---\n\nIf you like, I can compare 3\u20135 models currently in stock near you (U.S.) that hit Flush = \u201csomething as powerful as yours\u201d, and let you choose by budget. Want me to pull up a list like that?"

([totousa.com](https://www.totousa.com/filemanager_uploads/product_assets/SpecSheet/SS-02019_CST776CSFG.10.pdf?utm_source=openai))  \n- **Elongated Bowls & Comfortable Height**: All three have elongated bowls. Champion 4 and Cimarron offer chair/comfort height options (17-19\u2033 bowl rim) which many find more comfortable.

At 1.6 GPF, or close to it, this helps determine whether it\u2019s \u201cthe best Kohler makes\u201d for solids.\n\n---\n\n## What Is Revolution 360?\n\nRevolution 360 is Kohler\u2019s newer high-performance flush design with several innovations:\n\n- **AquaPiston\u2122 canister**: This replaces the traditional flapper system. It lets water flow into the bowl from *multiple sides* before pushing it out through a single powerful outlet, maximizing flow and reducing wasted water. ([kohler.com](https://www.kohler.com/en/inspiration/articles/bathroom/toilet-flushing-performance-toilet-flushing-technology?utm_source=openai))  \n- **Swirl flush around the bowl**: Water spills from the canister and flows all around the rim into the bowl, creating a 360-degree \u201cswirl\u201d effect. This gives full-coverage cleaning of bowl surfaces. ([kohler.com](https://www.kohler.com/en/inspiration/articles/bathroom/revolution-360-swirl-flushing-technology?utm_source=openai))  \n- **CleanCoat\u2122 surface & ContinuousClean option**: These are treated surfaces and additives that make the bowl resist stains, scale, and grime\u2014helping it stay clean longer. Not directly about flush strength, but help reduce the need for scrubbing. ([kohler.com](https://www.kohler.com/en/products/toilets/shop-toilets?facets=Collections%3ACorbelle%2CRevolution_360%3AYes&utm_source=openai))  \n\n---\n\n## Performance Testing & \u201cHard Stool\u201d Clearing?\n\nThere\u2019s *some* info and user feedback but not a ton of rigorous lab data comparing Revolution 360 directly with Kohler\u2019s other systems or with \u201chard stool\u201d tests (like those used by MaP, etc.).\n\nWhat is known:\n\n- Kohler claims Revolution 360 \u201cgenerates a forceful swirling motion to keep the bowl clean longer\u201d and \u201cincreasing the power and effectiveness of the flush.\u201d ([techcomm.kohler.com](https://techcomm.kohler.com/techcomm/pdf/K-46018_spec_US-CA_Kohler_en.pdf?utm_source=openai))  \n- Their internal testing includes the \u201cKOHLER B.O.L.D.\u201d system: Bulk-Waste Removal, Overall Cleanliness, Light-Waste Removal, and Does Not Clog. Revolution 360 is designed to pass those difficult cleaning and clogging tests. ([kohler.com](https://www.kohler.com/en/inspiration/articles/bathroom/toilet-flushing-performance-toilet-flushing-technology?utm_source=openai))  \n\n---\n\n## Strengths & Weaknesses vs. Hard Stools\n\nHere\u2019s how it performs compared to your current setup (1.6 GPF, elongated, Tornado-flush style) and what you might expect:\n\n| What helps with hard stools | How Revolution 360 stacks up |\n|-----------------------------|-------------------------------|\n| **High water flow + large valve** | Revolution 360 doesn\u2019t exactly match the large 3- or 4-inch flush valve you\u2019d see in something like the Champion 4; instead, it focuses on efficient valve design and maximizing flow from the tank with AquaPiston. The flow is brisk, and the swirl gets water around the bowl fast. ([kohlerasiapacific.com](https://www.kohlerasiapacific.com/press-releases/revolution-360.html?utm_source=openai)) |\n| **Strong trapway & siphonic action** | It uses fully glazed trapways; in many models the trapway is exposed (or skirted), but sized decently. Siphonic pull is aided by the swirl effect. However, some user feedback suggests it\u2019s still not as emphatic as Champion\u2019s or high-pressure systems. ([reddit.com](https://www.reddit.com/r/Plumbing/comments/1lyfg4j/kohler_cimarron_revolution_360_vs_toto_drake_vs/?utm_source=openai)) |\n| **Water used per flush (GPF)** | Many Revolution 360 models are 1.28 GPF (for water efficiency), which means less total force behind each flush compared to 1.6 GPF models. Kohler does offer 1.6 GPF Revolution 360 Highline models, which will come closer in performance. ([kohler.com](https://www.kohler.com/en/products/toilets/shop-revolution-360-toilets?facets=Revolution_360%3AYes%2CCollections%3AHighline&utm_source=openai)) |\n\n---\n\n## So, Is It Kohler\u2019s Best for Hard Stools?\n\nWith what I\u2019ve found:\n\n- **It\u2019s very good**. Revolution 360 is among Kohler\u2019s top gravity-fed flush systems\u2014especially in terms of keeping bowls clean, resisting clogging, and overall performance. It\u2019s a solid choice if you want a modern, efficient, low-maintenance toilet.\n- **But maybe not the absolute best**\u2014at least for *maximum bulk waste removal*. If hard stools are a regular challenge and \u201cone flush\u201d solutions are needed every time, something like a KOHLER Class-Five flush (in Kohler\u2019s lineup) or perhaps Kohler\u2019s pressure-assist models, or other brands like American Standard Champion, may outperform it on sheer raw force. Reputation among users generally places Champion 4 and Toto\u2019s Tornado closer to \u201cflush magic\u201d in that category. Reddit and user forums tend to favor Toto Drake or Champion 4 in the fight against hard clogs. ([reddit.com](https://www.reddit.com/r/Plumbing/comments/1lyfg4j/kohler_cimarron_revolution_360_vs_toto_drake_vs/?utm_source=openai))\n\n---\n\n## Verdict\n\nIf you\u2019re choosing among Kohler options, Revolution 360 models (especially the 1.6 GPF ones) are excellent picks. They offer a very good balance: strong flushing, cleaner bowls, less cleaning, modern tech, and water savings. But if you want everything\u2014**max bulk removal**, **maximum power in one flush every time**\u2014there *may* be Kohler pressure-assist or Class-Five models that edge ahead.\n\n---\n\nIf you want, I can compare Revolution 360\u2019s 1.6 GPF Highline model with other Kohler options and see which\u2019s strongest in real-world tests. Want me to pull up that comparison?"

That helps clean the bowl surface and supports bowl rinsing, which can reduce sticking and lingering waste. ([me.kohler.com](https://me.kohler.com/revolution-360/?utm_source=openai))\n\n2. **Decent Trapway Size**  \n   A 2-1/8\u2033 fully glazed trapway is pretty standard for gravity-fed toilets. It\u2019s not massive like pressure-assist or power-flush toilets, but its smooth glaze helps waste pass more easily. ([techcomm.kohler.com](https://techcomm.kohler.com/techcomm/pdf/K-30811_spec_US-CA_Kohler_en.pdf?utm_source=openai))\n\n3. **Solid Bowl Design & Chair Height**  \n   With elongated and chair-height bowls, you get a bigger bowl (more water area) and more comfort. Chair height can help with force and angle of exit flow. ([techcomm.kohler.com](https://techcomm.kohler.com/techcomm/pdf/K-30811_spec_US-CA_Kohler_en.pdf?utm_source=openai))\n\n4. **AquaPiston Canister instead of Flapper**  \n   Less seal area = fewer leaks & less resistance. This tech is intended to give a strong hit of water without needing a full-on pressure or vacuum assist. ([la.kohler.com](https://la.kohler.com/en/product-detail/44468-RA?skuid=K-44468-RA-0&utm_source=openai))\n\n5. **Water Usage Matched to Older Standards**  \n   At 1.6 GPF, these match many older toilets. If your current toilet is already 1.6 GPF, water usage won\u2019t go down\u2014but performance may slightly improve with newer designs.  \n\n**Potential Limitations:**\n\n- **Trapway Size is Moderate**  \n  For especially hard or bulky waste, some gravity models struggle no matter how well designed. Bigger flush valves (like the 4\", or pressure-assisted systems) generally offer more brute force.  \n\n- **Break-In Period**  \n  These newer Revolutions may need multiple flushing to \u201cprime\u201d bowl wall wetness and ensure every surface is being cleaned well. If fluids stay low, solid matter may hang unless force is high.\n\n- **No Dual-Flush Separation**  \n  All of the 1.6 GPF Revolution 360 models are single-flush. You get full power always\u2014but also no chance to use less water for lighter needs.\n\n---\n\n## Verdict: How Good Are They for \u201cHard Stool\u201d Problems?\n\nIf your benchmark is something like \u201cone flush, no clog, full waste removal, no leftovers,\u201d here\u2019s how they measure up:\n\n- **Better than many older 1.6 GPF models.** The swirl + AquaPiston combo gives cleaner rim coverage and a stronger water flow than some older gravity toilets without those features.\n\n- **Not quite as powerful as pressure or large-valve toilets.** For some users with really heavy flush needs, these may still need two flushes or risk partial clogs with particularly tough waste.\n\n- **Still solid if you match bowl and trapway well.** If you install a 1.6 GPF Revolution 360 with a big bowl, a good trapway, and ensure it's clean\u2014these can come close to \u201cbest in Kohler\u201d status among gravity systems.\n\n---\n\nIf you like, I can pull up some MaP test scores for these Kohler 1.6 GPF Revolution 360 models *and* compare them to Challenger models like Champion 4 or Toto Drake so you can see how they stack up numerically."

([manualshelf.com](https://www.manualshelf.com/manual/toto/ms854114sg-01/specification-sheet-english/page-1.html?utm_source=openai)) |\n\n---\n\n## How They Perform on Hard Stool Clearance\n\nWhen it comes to flushing hard or bulky waste (your \u201cworst-case scenario\u201d test), what really matters tends to be:\n\n- Volume and force of water (how fast the tank dumps water), which depends on flush valve size & design\n- Shape and diameter of trapway\n- Bowl shape, water surface (affects splash & sweeping action)\n- Surface treatments to reduce sticking\n- How consistent and powerful the flow is around the bowl (rings vs multiple rim holes)\n\n**TOTO\u2019s Tornado Flush**, especially in their Drake or UltraMax lines, has a strong track record with MaP testing for clearing large amounts of solid waste. For example, the Drake\u2019s specs show it has ceded few complaints in performance and many users say it \u201cflushes everything in one go.\u201d ([reddit.com](https://www.reddit.com/r/Plumbing/comments/1lyfg4j/kohler_cimarron_revolution_360_vs_toto_drake_vs/?utm_source=openai))\n\n**Kohler\u2019s Revolution 360** is newer, and while Kohler claims improvements\u2014swirl around the full rim, stronger flush valve in many models, and rigorous internal testing (KOHLER B.O.L.D.)\u2014it\u2019s still catching up in published MaP numbers. Many Revolution 360 toilets are tested at 1.28 GPF, which inherently have less water volume per flush, reducing brute force. Only a subset are 1.6 GPF. ([kohler.com](https://www.kohler.com/en/products/toilets/shop-revolution-360-toilets?utm_source=openai))\n\n---\n\n## Trade-Offs, Strengths & Weaknesses\n\nHere are pros and cons of each system relative to hard stool removal:\n\n| System | Strengths | Weaknesses |\n|---|-----------|-------------|\n| **Kohler Revolution 360 (1.6 GPF)** | \u2022 Stronger rim-to-bowl swirling action gives better wet-wall coverage. <br> \u2022 AquaPiston valve (less restrictive than flapper) often leads to more consistent flush. <br> \u2022 CleanCoat and rimless/bowl designs in some models help with cleanliness and possibly reduce sticking. | \u2022 The 1.6 GPF models are fewer in number; many options are 1.28 GPF, which reduces potential power. <br> \u2022 Trapway diameter is still modest. <br> \u2022 Claims of \u201ckicks ass\u201d from Kohler are new; long-term user proof vs TOTO is still growing. <br> \u2022 As with many revolutionary designs, bowl/water interface might take a few cycles to \u201cprime\u201d (wet the bowl walls for optimal flow). |\n| **TOTO Tornado Flush (1.6 GPF)** | \u2022 Long established. Many models get very high MaP scores. <br> \u2022 Dual nozzles + centrifugal rinse action are excellent at sweeping waste from high up in the bowl. <br> \u2022 CEFIONTECT glaze gives a very smooth surface. <br> \u2022 Large water area surface in many models helps splash suppression and contact with waste. | \u2022 With every flush having full force, water use remains at 1.6 GPF (Kohler has lots of 1.28 options). <br> \u2022 Tank & bowl design still uses traditional flapper or equivalent (though performance is excellent). <br> \u2022 Some bowl designs don\u2019t rinse the entire wall as well as the newest designs (rim holes can miss areas compared to swirl or jet designs). |\n\n---\n\n## Verdict: Which Handles Hard Stool Better?\n\nIf I had to pick based on current data and real-world feedback:\n\n- **TOTO\u2019s 1.6 GPF Tornado Flush models** are still likely ahead when it comes to raw one-flush power, especially for extremely hard stools. They have existing legacy, widespread user satisfaction, proven MaP results, and their bowl dimensions & jet design deliver strong siphonic/rinsing force. If your priority is \u201cone flush, forget I have a toilet that struggles,\u201d TOTO seems the safer bet.\n\n- **Kohler Revolution 360 (1.6 GPF)** is very capable and making advances. If you get a model with the 1.6 GPF option (not the water-saving 1.28 GPF version), with an appropriate trapway and water surface size, it might come very close to TOTO for many users. Also, the cleaning and swirl bowl coverage may help reduce issues over time (less sticking, easier to clean, fewer clogs from buildup).\n\nSo, Kohler is catching up (or may be there in many use cases), but for sheer consistency in brutal flush scenarios, TOTO Tornado Flush is still \u201ctop dog\u201d for now\u2014unless you go with one of Kohler\u2019s strongest 1.6 GPF Revolution 360 models.\n\n---\n\nIf you want, I can pull up MaP scores (grams cleared) for a few Kohler Revolution 360 1.6 GPF models and a few top TOTO Tornado 1.6 GPF models so you can see how they compare in numbers."
