What to Know When Choosing a Toilet Understanding Height, Flush Systems, Bowl Shapes & Modern Options

Choosing a toilet might seem straightforward, but there are several important differences that affect comfort, performance, installation, and overall satisfaction. Understanding these options will help you choose a toilet that fits your space, your plumbing, and your lifestyle.

Height

One of the most noticeable differences between toilets is height. Standard height toilets are typically around 15 to 16 inches from the floor to the top of the seat. This traditional height works well for children and shorter individuals, and it is still common in many homes.

Comfort height toilets, also known as easy height or universal height, measure about 17 to 19 inches from the floor to the top of the seat. This slightly taller design makes sitting down and standing up much easier, which is why many adults prefer it. Comfort height toilets are often ADA-compliant and are especially recommended for seniors or anyone looking for improved accessibility and long-term comfort.

Bowl Design

Toilets generally come in two bowl shapes: round and elongated. Round bowls are more compact and take up less space, making them ideal for smaller bathrooms or powder rooms. They are practical where space is limited, but they offer slightly less seating room.

Elongated bowls extend a few inches further forward, creating a more spacious and comfortable seating area. Most homeowners prefer elongated bowls in primary bathrooms because they feel more comfortable and modern. If your bathroom layout allows for the extra space, elongated is typically the preferred option.

Flush Type

The flush system determines how effectively the toilet clears waste and how much water it uses. Gravity flush toilets are the most common in residential homes. They rely on water stored in the tank to create flushing pressure. These systems are generally quiet, reliable, and easy to maintain.

Dual flush toilets offer two buttons or options: a lighter flush for liquid waste and a stronger flush for solid waste. This design helps conserve water and reduce utility costs over time.

Pressure-assisted toilets use compressed air inside the tank to create a more powerful flush. They are excellent for preventing clogs and are often found in high-traffic bathrooms. However, they can be louder than standard gravity models.

Mount Type

The way a toilet is installed affects both appearance and maintenance. Floor-mounted toilets are the most common and easiest to install. They work with standard plumbing and are generally the most affordable option.

Wall-mounted toilets attach directly to the wall and have the tank concealed inside the wall. This creates a floating look and makes floor cleaning easier. Wall-mounted models are popular in modern designs but require an in-wall carrier system and professional installation.

One-Piece vs. Two-Piece

Two-piece toilets have a separate tank and bowl. They are typically more affordable and easier to transport. One-piece toilets have a seamless design where the tank and bowl are fused together. They offer a cleaner, more modern appearance and are easier to clean because there are fewer crevices.

Tankless

Tankless toilets use direct water pressure from the plumbing line instead of storing water in a tank. They provide a strong, fast flush and a sleek appearance but require adequate water pressure and proper plumbing setup.

Smart Toilet Options

Smart toilets add comfort and convenience features that go beyond traditional flushing. Many include built-in bidets with adjustable water temperature and pressure, heated seats, air dryers, automatic flushing, night lights, and motion-sensor lids. Some even include deodorizing systems. These models are ideal for homeowners seeking a luxury experience, but they require access to electricity.

Water Efficiency

Modern toilets are designed to use less water than older models. High-efficiency toilets typically use 1.28 gallons per flush, compared to older models that used 1.6 gallons or more. Dual flush models can reduce water consumption even further. Choosing a water-efficient toilet can help lower monthly water bills while remaining environmentally responsible.

Rough-In Measurement

Before purchasing any toilet, it’s essential to measure the rough-in. This is the distance from the wall behind the toilet to the center of the floor drain. The standard rough-in size is 12 inches, but some homes have 10-inch or 14-inch rough-ins. Buying a toilet that matches your rough-in ensures proper fit and installation.

Final Considerations

When selecting a toilet, think about who will be using it, how much space you have, your plumbing setup, and the level of comfort or luxury you want. Comfort height and elongated bowls are popular for everyday comfort, while wall-mounted or tankless designs offer a more modern aesthetic. Smart features add convenience, and high-efficiency models help save water.

Choosing the right toilet is about balancing comfort, performance, design, and practicality. With the right information, you can select a model that will serve your household reliably for years to come.
