Best Low Flow Toilets to Save Water

Flushing the toilet takes up more water than any other activity in your home, accounting for up to 30% of a person’s daily water usage. If you have an older style toilet installed in your home, this will mean thousands of gallons of water literally flushed down the toilet every year.

However, today’s toilets are a lot more water efficient thanks to federal mandates that restrict the amount of water used per flush, making them more environmentally friendly. With all the brands and models available on the market, finding one for your bathroom can be quite overwhelming but don’t worry, we’re here to help. Let’s take a look at 6 of the best low flow toilets available on the market right now.

1. Toto MS992CUMFG#01 Washlet with Integrated Toilet
as of December 7, 2023 7:27 pm


  • Water-efficient
  • WaterSense Certified
  • Automatic hands-free flush
  • Comes with night light
  • Sleek, modern shape and design
  • Heated seat with temperature control
  • ADA Compliant


  • This is a one-piece unit without a replaceable or detachable tank
  • Comes with a high-end price tag

The Neorest Dual Flush toilet is one of the most unique and luxurious smart toilets designed by Toto. This smart toilet is built to conserve water, using up only 1 gallon per flush. It features a hole-free rim design which allows for dual-nozzle bowl cleansing.

This creates a centrifugal rinsing action that works together with EWATER + technology, resulting in a cleaner toilet bowl that stays clean without having to use harsh chemicals. You’ll be pleased to find that you won’t have to keep cleaning the toilet as often as you used to.  

The toilet comes with several impressive features including a night light, so you won’t have to stumble around in the dark on those late-night trips to the bathroom. Its auto-flush technology offers hands-free usage, making it convenient and much more hygienic than the standard toilet.

What we liked about this toilet was that it allows you to adjust the water pressure and temperature settings according to your preference. It also has an auto open-and-close feature that kicks into action whenever the toilet seat senses you approaching or departing.

Certified by WaterSense, the toilet is made from top quality materials as one integral device, with the seamless combination of the toilet and the washlet, ensuring durability and longevity. Although it’s priced in thousands of dollars, the pleasures it offers make it well worth the cost.

2. Woodbridge T-0019 Dual Flush Elongated One-Piece Toilet
as of December 7, 2023 7:27 pm


  • Aesthetically pleasing
  • Comfort height seating for adults and elderly
  • Dual-flush system offering two GPF options depending on your flushing needs
  • WaterSense certified
  • ADA compliant
  • Low water consumption


  • May be challenging for children to use
  • Dual flush system can be confusing

The Woodbridge T-0019 is an excellent mid-range low flow toilet that’s also reasonably priced. With its luxurious, modern look and standard size, this toilet will fit easily in any standard bathroom without the need for any renovations.

The seat of this toilet is slightly under 18 inches in height making it easier for adults to use since it’s about the same as a standard chair. The lid is soft closing to prevent it from slamming shut which is perfect when you’re trying to be quiet in the middle of the night. Compared to most other toilets, this model doesn’t have any grooves or corners for dirt to get stuck in due to its design and the skirted tramways which means it’s extremely easy to clean.

With a dual flush system that allows you to use both half flush (for liquid waste) and a full flush (for solid waste), the Woodbridge toilet uses up to 1.6 gallons per full flush. The half flush uses only 1.0 GPF and thanks to its siphon flushing design, everything is promptly removed without any residue left behind.

The best part about this toilet is that it comes with everything necessary for installation including a wax ring, floor bolts and seat with stainless steel hinges so there’s no need to worry about finding extra items in the middle of the installation process.

3. Low Flow N7717 Niagara Stealth Toilet
as of December 7, 2023 7:27 pm


  • Extremely low water usage – 0.8 GPF
  • Elegant design
  • WaterSense certified
  • Noise-cancelling tank to minimize disturbances in the night
  • ADA compliant


  • Slightly bulky unit not ideal for small bathrooms
  • Toilet seat must be purchased separately
  • Bolts for installation are not included

The Niagara Steal N7717 water-conserving toilet is one of the most popular and top-rated models on the market right now due to its highly efficient flush that takes up only 0.8 gallons of water with each use. The tank is specially designed with a noise-cancelling fill valve that minimizes noise, ensuring that there won’t be any disturbance during the night.

Although this toilet uses less water per flush than other models, its well-engineered system clears the bowl with just one flush every time. This ensures that there’s no need to flush twice and waste water. Made from vitreous china, it looks almost exactly like the standard two-piece toilets, the only difference being that it’s a more efficient piece of hardware.

The Niagara stealth toilet meets the WaterSense certification and is the only model classed as a U-HET (ultra-high efficiency toilet). Although it’s easy to install due to its similarity to other standard toilets, it doesn’t include the bolts necessary to fix it to the floor. This means a bit of extra hassle for you having to find the right sized bolts. Other than that, the toilet is an excellent and high quality model that works great in just about any bathroom.

4. India Reserve Elongated 2-Piece Bathroom Toilet
as of December 7, 2023 7:27 pm


  • Slow-closing toilet seat included
  • ADA compliant
  • Water Sense certified
  • Dual push-button flush
  • Attractive green glitzy design
  • Reasonably priced


  • Bolt covers are not included

This low flow Dual Flush toilet from India Reserve is a dependable and valuable fixture for any bathroom due to its attractive design, ease of use and ability to conserve water. The push-button dual flush system of this toilet uses only 0.8 GPF for liquid waste and 1.6 GPF for solid waste which is a lot less than the standard single-flush toilets, saving you up to 25,000 gallons of water per year.

Made of quality porcelain with an antique finish, this model is above industry standard quality and is built to last. It features a slow-closing elongated seat with an elegant curved lid design, both of which are made from high density plastic. We were impressed by the efficiency of this model and how well it flushes, leaving behind a clean bowl with no residue unlike most other toilets.

While this toilet does a great job of flushing away waste, it does have its drawbacks as well. The two-piece model is slightly harder to clean than single units since some areas are difficult to reach. Due to this reason, getting every nook and cranny sparkling can be a real feat. You’ll also find that bolt covers are not included with this unit so they’d need to be bought separately for installation.

5. Swiss Madison Well Made Forever Ivy SM-WT450 Wall Hung Toilet

as of December 7, 2023 7:27 pm


  • Elegant, modern design
  • Meets strict EPA flushing guidelines
  • Environmentally friendly
  • Uses less water
  • Extra room and comfort
  • Perfect for tiny bathrooms


  • The tank is difficult to access once installed

The Swiss Madison Well Made Forever Ivy dual flush toilet comes under the category of environmentally friendly toilets while also meeting strict EPA flushing guidelines.  This wall-mounted toilet is designed for maximum relaxation and comfort. It features a dual-flush system offering a 0.8 or 1.28 GPF to suit your needs and works effectively while using less water, saving you money on water and energy bills in the long run.

The Swiss Madison toilet comes with a soft closing seat which closes quietly and slowly to prevent slamming, unnecessary noise or breaking. We loved its sleek, seamless, one-piece design which allows for hassle-free cleaning while easily fitting in with and complimenting practically all bathroom fixtures and décor.

What we didn’t like about this model is that while its hidden tank improves the appearance of your bathroom, it can be difficult to access in case of repairs. Once bolted in place, you’d have to remove an entire portion of your wall to access the tank when necessary, unless you have an access panel. Apart from this, it’s a convenient and top-quality toilet that you can easily install and use in your bathroom.

6. Toto CST744SR#01 Drake Two-Piece Elongated Toilet
as of December 7, 2023 7:27 pm


  • Pressure-assisted flushing mechanism for maximum efficiency and flushing power
  • Universal Height for maximum comfort
  • Uses 20% less water than conventional toilets
  • Easy to clean
  • Concealed design creates a smooth and sleek look


  • Does not include additional items for installation

Our final pick is another low flow toilet from Toto which is a two-piece model that’s precision-engineered to use 20% less water than other conventional toilets. The two-piece Drake uses advanced flushing technology to deliver a strong and powerful yet quiet flush leaving the bowl perfectly clean of waste.

This toilet features CEFIONTECT glazing which gives the bowl a lubricious quality, making it a lot easier to clean and preventing particles from adhering to it which means it stays cleaner for longer. This is an added bonus since it not only reduces the frequency of toilet cleanings, but also minimizes the use of harsh chemicals, water and the time spent on cleaning.

The Drake toilet comes with a left-hand chrome trip lever and is designed in Toto’s Universal Height, allowing for more comfortable seating for users. Although this model is easy to install in almost any bathroom, it does not include addition items needed for installation. Such items like the wax ring, water supply lines, toilet mounting bolts and even the toilet seat must be purchased separately in which case the price of this model is questionable.
