Are Tankless Toilets Any Good?

Tankless toilets are good with several advantages over toilets with tanks. Here are some reasons why tankless toilets are highly regarded.

• Water efficiency

Tankless toilets are highly water-efficient. They use advanced flushing mechanisms, such as pressure-assisted or dual-flush systems, which consume less water per flush than toilets with tanks. It not only helps to conserve water but also reduces water bills over time.

• Space-saving design

Tankless toilets have a compact and streamlined design since they do not have a water tank. It makes them an excellent choice for smaller bathrooms or spaces where maximizing floor area is important. These space-saving toilets can create a more spacious and visually appealing bathroom environment.

• Continuous flushing

Tankless toilets provide continuous flushing, directly using water from the water supply line. Unlike toilets with tanks, there is no risk of running out of water during consecutive flushes, making them suitable for high-traffic areas or households with multiple users.

• Durability and maintenance

Tankless toilets come with fewer parts and components compared to toilets with tanks. It results in lower maintenance requirements and potentially fewer repairs over time. Also, without a water tank, there is no risk of tank-related issues such as leaks, cracks, or condensation.

• Versatile installation options

Tankless toilets offer greater flexibility in terms of installation. They can be wall-mounted or floor-mounted, allowing for installation in various locations. These toilets can accommodate different bathroom layouts and plumbing configurations.

• Modern aesthetics

Tankless toilets are known for their sleek and modern design. They add a touch of elegance and contemporary style to any bathroom decor. Their minimalist appearance can enhance the overall aesthetics of the space.

How Do Tankless Toilets Work?

Tankless toilets, or flushometer or pressure-assisted toilets, operate differently from traditional gravity-fed toilets. Instead of relying on a water-filled tank to initiate the flush, tankless toilets use a pressurized water supply directly from the plumbing system.

Here’s a detailed process for how tankless toilets work.

• Flush Valve

Tankless toilets have a flush valve, also known as a flushometer valve, connected directly to the water supply line. The flush valve is typically a diaphragm-operated valve that controls the release of water into the toilet bowl.

• Pressurized Water Supply

When the user activates the flush by pressing a lever or button, the flush valve opens, rapidly allowing pressurized water from the supply line to enter the toilet bowl. The high-pressure water creates a powerful force that clears waste from the bowl.

• Efficient Flushing

The rapid influx of pressurized water creates a strong siphonic or jet action that propels waste down the trapway and into the sewer line. This flushing mechanism is more efficient than gravity-fed toilets, as it uses the force of the pressurized water to ensure thorough waste removal.

• Quick Refilling

The flush valve closes once the flush is complete, cutting off the water supply. Unlike traditional toilets that rely on the tank to refill gradually, tankless toilets have a fast refilling process due to the direct pressurized water supply. It allows the toilet to be ready for the next flush almost immediately.

• No Tank

As the name suggests, tankless toilets do not have a traditional water tank. Instead, they rely on the plumbing system’s continuous supply of pressurized water. This design eliminates the need for a large tank, making tankless toilets more compact and suitable for smaller spaces.

• Water Pressure Requirement

It’s important to note that tankless toilets require a certain level of water pressure to operate effectively. The water supply must meet the minimum pressure requirements specified by the manufacturer. If the water pressure is too low, it can affect the toilet’s flushing performance.

Ultimate Guide to Buy a Best Tankless Toilet

When it comes to tankless toilets, not all options are created equal. Some outperform others, while some have a more aesthetically pleasing design. Also, certain tankless toilets have a longer lifespan than their counterparts. Of course, cost is also crucial, as some models may be more expensive than others.

To help you make the right decision, here are the essential factors to consider when buying a tankless toilet.

• Price

The first thing you need to consider is the cost of tankless toilets. Tankless toilets have a higher price tag compared to traditional tank toilets. However, there can be significant price variations even within the tankless category.

Evaluating your budget and determining how much you’re willing to spend is important. Also, factor in the repairs and maintenance costs, as more expensive toilets often come with pricier replacement parts.

• Mounted Type

Tankless toilets can be wall-mounted or floor-mounted.

Wall-mounted toilets often come at a higher price and need professional installation due to the complexity involved.

Floor-mounted toilets are more common and easier to install. Consider your budget, installation requirements, and bathroom design when choosing between the two.

• Flushing Performance

Despite being tankless, some models have modified tanks or macerator pumps to aid flushing. Understanding the flushing capacity and effectiveness of your chosen toilet is crucial.

Look for wider inlets, pressurized rims, and enhanced suction to compensate for the reduced flushing capacity. Don’t hesitate to ask for a demo and seek clarification on any technical terms related to flushing performance.

• Dual Flush or Single Flush

Some tankless toilets offer dual flush options, allowing users to choose between a lower water volume for liquid waste and a higher volume for solid waste.

Single-flush toilets have a single option for flushing. Dual flush toilets provide water-saving benefits by allowing you to use less water when appropriate.

• Gallons Per Flush

Consider the amount of water required per flush. Water-efficient toilets use as little as 0.8 gallons for liquid waste and 1.28 gallons for solid waste.

Avoid toilets that use excessive water, as it increases water bills and negatively impacts the environment.

• MaP Score

The MaP (Maximum Performance) score indicates the toilet’s ability to remove solid waste through the trapway efficiently.

Higher MaP scores, such as 1000g, indicate better performance and a reduced likelihood of clogging. Consider the MaP score when evaluating the toilet’s flushing efficiency.

• Comfort

The best thing about tankless toilets is that they prioritize comfort by offering features like heated seats, elongated bowls and seats, adjustable seat height, nightlights, automatic flushing, and lid opening/closing. While comfort levels vary between models, tankless toilets generally provide many options.

• Toilet Dimensions

Tankless toilets are a great fit for both large and small bathrooms. However, if you have limited space, carefully considering each toilet model’s dimensions is crucial.

Don’t rely solely on e-commerce websites for dimensions, as those are often shipping dimensions. Visit the manufacturer’s website and download the toilet’s specification sheet for accurate measurements.

• Toilet Rough-In

The rough-in refers to the distance between the rear wall and the center of the toilet’s drainpipe.

Standard rough-ins are typically 12 inches, although 10- and 14-inch options also exist. Measure your toilet’s rough-in before purchasing a tankless toilet.

If your bathroom has a non-standard rough-in, consider buying an offset toilet flange to accommodate a tankless toilet with a 12-inch rough-in. Offset toilet flanges can convert 10- or 14-inch rough-ins to 12-inches.

• Legal Requirements

Keep in mind that certain states have specific regulations regarding toilet water usage.

For example, in California, toilets sold must not exceed 1.28 gallons per flush. Public facilities must also comply with the Americans with Disabilities Act (ADA), which mandates a comfortable seat height of 17-19 inches.

Additional Considerations

• Physical Measurements

Pay attention to the height and length of the toilet. Round-shaped seats are typically 16 inches long, while elongated or D-shaped toilets are around 18 inches long.

Consider your bathroom size and personal comfort preferences when choosing the seat length. Additionally, toilets come in different height categories, with Comfort Height toilets being taller (17 inches or more) and ‘Normal’ toilets described as Right Height, Standard Height, or Universal Height, typically measuring 15 to 16 inches.

Double-check whether the stated dimensions include the seat or not, as it can impact the overall height of the toilet. For accurate measurements, measure your rough-in distance from the baseboard, not the wall.

• Disturbance Levels

The flushing mechanism of a tankless toilet plays a significant role in water usage, noise levels, and flushing efficiency. Consider the noise levels of the toilet, especially if you have small children, work odd hours, or live with elderly individuals.

Look for features like built-in night lights and slow-closing lids to minimize disruptions. Additionally, pay attention to the quality of the toilet seat hinges to ensure durability and prevent noisy slamming.

• Bowl Shape

Tankless toilets come in two main bowl shapes: round and elongated.

Round-shaped bowls are smaller and save space, making them suitable for compact bathrooms.

Elongated bowls offer a more comfortable seating posture.

Consider your space requirements and comfort preferences when selecting the bowl shape.

• Color

While white toilets are the most popular due to their clean appearance, tankless toilets offer more flexibility in color choices. Black toilets, for instance, are gaining popularity. However, sticking with white is a safe and timeless choice for tankless toilets.

• Power Reliability

Tankless toilets rely on electricity to operate effectively. If you live in an area prone to frequent power outages, you may not fully enjoy the benefits of a tankless toilet. Consider your location’s power stability before making a decision.

Final words

When selecting the best tankless toilet, you must consider all essential features. These sleek and efficient toilets without tanks offer a range of benefits, including water efficiency, space-saving design, and powerful flushing capabilities. Each aspect plays a role in making an informed decision, from cost and color options to power reliability and comfort features. By carefully evaluating your requirements and preferences, you can confidently choose a tankless toilet that not only meets your functional needs but also enhances the overall aesthetics of your bathroom.
