Tankless Toilet vs Tank Toilet

Design, Size and Space Considerations

Tankless toilets have a sleek design and are often more compact compared to traditional tank toilets. They don't have a bulky tank attached to the bowl, which allows them to fit into smaller spaces. This makes them ideal for modern bathrooms with limited room.

Tank toilets, on the other hand, have a more traditional design with a tank sitting atop the bowl. This design uses gravity to flush the water. While they may take up more space, they are functional even without electricity.

When it comes to bathroom space, tankless toilets for small bathrooms have a clear advantage. Their compact design can save valuable room, allowing for more flexibility in bathroom layout. This is particularly useful in small apartments or homes with limited space.

Comparison Table

Tankless Toilet
Tank Toilet
Modern, sleek, no tank
Traditional, tank on top
Compact, space-saving
Larger, requires more space
Ideal for small bathrooms
May be less suitable for cramped spaces
Requires consistent water pressure, may need electricity
Functional without electricity

It's important to consider both the design and space implications when choosing between these two types of toilets.

Smaller bathrooms might benefit more from the compact nature of a tankless toilet, while larger bathrooms can accommodate the bulkier design of a tank toilet.

Flushing System

Tankless Toilets:

  • Flushing Mechanism: Uses electric pumping pressure to flush.
  • Water Source: Directly from the pipes.
  • Design: Modern and minimalistic.
  • Space: More space-efficient.


  • Reduces water usage.
  • The sleek design fits well in modern bathrooms.


  • Requires a power supply.
  • More complex installation.

Tank Toilets:

  • Flushing Mechanism: Gravity-powered.
  • Water Source: Water stored in a tank.
  • Design: Traditional and bulky.
  • Space: Requires more room due to the tank.


  • Simple, reliable flushing system.
  • No need for a power supply.


  • Uses more water per flush.
  • Takes up more space.

Both types serve different needs based on bathroom design and water usage preferences.

Tankless Toilet vs Tank Toilet

Performance and Efficiency

Tankless Toilets

Tankless toilets use high-pressure water directly from the pipes to flush. This mechanism results in efficient waste removal and keeps the bowl clean for a longer time.

By using less water per flush, tankless models contribute significantly to water conservation.

Tank Toilets

Tank toilets store water in a tank and release it when flushed. Earlier models use up to 3.5 gallons per flush, while modern ones comply with the federal limit of 1.6 gallons per flush.

Although effective, they often use more water compared to tankless options.

Water Comparison

Tankless Toilets
Tank Toilets
Water Per Flush
Less than 1.6 gallons
Up to 3.5 gallons (modern models use 1.6 gallons)
Cleaning Efficiency
High due to strong water pressure
Moderate, relies on tank refill
Water Source
Direct from pipes
Stored in a tank

Tankless toilets provide quicker and more powerful flushes, reducing the risk of clogs. Conversely, tank toilets may take longer to refill but are usually quieter when flushing.

Energy Use

Tankless toilets often require electricity to power their pumps, potentially increasing utility costs. Tank toilets do not require electricity, making them a better choice for places with unreliable power.

Both types of toilets offer specific advantages in performance and efficiency. The best choice depends on individual needs and environmental priorities.

Installation Plumbing

When it comes to installing tankless and tank toilets, the plumbing requirements differ significantly.

Tank Toilets:

  • Water Supply: Tank toilets need a standard water supply line. This setup is usually straightforward, involving a hose connecting the supply line to the tank.
  • Installation Time: These toilets are generally quicker to install and don't require specialized knowledge.
  • Space: They need more floor space due to the tank.

Tankless Toilets:

  • Water Supply: Tankless toilets often need a high-pressure water supply. This setup is more complex and may require professional installation.
  • Installation Time: Takes longer because they may need new plumbing lines or adjustments to existing ones.
  • Space: Ideal for small bathrooms as they don't have a bulky tank. They can be mounted directly on the wall, saving floor space.

Tank toilets are more traditional and simpler to install, while tankless toilets offer a modern look and require more specialized plumbing.

For those who need a space-saving option, a tankless toilet might be the better choice. For those preferring a straightforward installation, a tank toilet could be more suitable.

Summary Table: Tankless vs Tank Toilet

In summary, while tank toilets are a traditional and common choice, they come with both benefits and drawbacks. The choice between a tank and tankless toilet depends largely on individual needs and bathroom specifications.

  • Design: Tankless toilets offer a more modern and streamlined look compared to the bulkier traditional models.
  • Space: The absence of a tank makes tankless toilets a better fit for smaller spaces.
  • Flushing Mechanism: Traditional toilets rely on gravity-fed flush systems, while tankless toilets use high-pressure water from the supply line.
  • Maintenance: Traditional toilets may require less frequent but simpler maintenance, whereas tankless models, with their advanced features, might need more specialized care.
