How to Choose a Toilet: Complete Toilet Buying Guide for Homeowners

Choosing the right toilet might not seem like a big decision—until you realize how much it impacts your daily comfort, water usage, and plumbing performance. Whether you’re remodeling your bathroom or replacing an old unit, understanding how to choose a toilet can save you money, prevent future plumbing issues, and improve your home’s efficiency.

In this complete toilet buying guide, we’ll walk you through everything you need to know—from size and flushing systems to water efficiency and installation—so you can confidently choose the best toilet for your home.

Why Choosing the Right Toilet Matters

A toilet isn’t just a fixture—it’s one of the most frequently used components in your home. The wrong choice can lead to:

Frequent clogs and backups
Higher water bills
Poor flushing performance
Uncomfortable seating height
Costly repairs or replacements

In areas like Central Texas, where hard water and high water pressure are common, selecting the right toilet is even more important. Mineral buildup and pressure fluctuations can affect performance over time, making quality and design essential.

Step 1: Understand Toilet Types

When learning how to choose a toilet, start by understanding the different types available.

1. One-Piece Toilets

Sleek, modern design
Easier to clean (fewer crevices)
Typically more expensive

2. Two-Piece Toilets

Most common and budget-friendly
Separate tank and bowl
Slightly harder to clean

3. Wall-Mounted Toilets

Contemporary look
Saves floor space
Requires special plumbing setup

4. Smart Toilets

Features like heated seats, bidet functions, and automatic flushing
Higher upfront cost but premium comfort

Pro Tip: For most homeowners, a two-piece toilet offers the best balance of affordability and reliability.

Step 2: Measure the Rough-In Size

One of the most overlooked steps in any toilet buying guide is measuring the rough-in—the distance from the wall to the center of the drain pipe.

Standard size: 12 inches
Other options: 10 inches or 14 inches

Choosing the wrong rough-in size can lead to installation issues or costly modifications.

Step 3: Choose the Right Bowl Shape

Toilet bowls come in two main shapes:

Round Bowl

More compact
Ideal for small bathrooms
Lower cost

Elongated Bowl

More comfortable for most users
Better for larger bathrooms
Slightly more expensive

If comfort is a priority, an elongated bowl is usually the better choice.

Step 4: Consider Toilet Height

Toilet height plays a big role in comfort and accessibility.

Standard Height (15 inches)

Traditional design
Suitable for children and shorter individuals

Comfort Height (17–19 inches)

Easier for adults to sit and stand
ADA-compliant options available

Most homeowners today prefer comfort-height toilets, especially for long-term use.

Step 5: Evaluate Flushing Systems

A toilet’s flushing system determines its performance and efficiency.

Gravity-Feed Flush

Uses gravity to move water
Quiet and reliable
Most common type

Pressure-Assisted Flush

Uses pressurized air for a powerful flush
Reduces clogs
Slightly louder

Dual-Flush Toilets

Two flush options:
- Low flush for liquid waste
- Full flush for solid waste
Helps conserve water

If you’re focused on efficiency and performance, dual-flush toilets are an excellent option.

Step 6: Look at Water Efficiency

Modern toilets are designed to use less water without sacrificing performance.

Standard Toilets

Use about 1.6 gallons per flush (GPF)

High-Efficiency Toilets (HET)

Use 1.28 GPF or less
Save thousands of gallons annually

Choosing a water-efficient model is not only eco-friendly but also reduces your utility bills—especially important in regions with high water costs.

Step 7: Check Trapway Size and Glazing

The trapway is the internal passage that carries waste from the bowl to the drain.

Larger trapways (2–2.5 inches) reduce clogging
Fully glazed trapways improve flow and prevent buildup

This is a key factor when deciding how to choose a toilet that won’t clog frequently.

Step 8: Consider Noise Levels

If your bathroom is near bedrooms or living areas, noise matters.

Gravity-fed toilets are quieter
Pressure-assisted models are louder but more powerful

Choose based on your household’s needs and layout.

Step 9: Evaluate Design and Style

Toilets come in a wide range of styles to match your bathroom design.

Modern vs. traditional
Skirted designs (hidden trapway for easier cleaning)
Color options (white is most common and easiest to match)

A well-chosen toilet can enhance the overall look of your bathroom.

Step 10: Don’t Forget Installation Requirements

Some toilets are easier to install than others.

DIY-Friendly Options

Standard two-piece toilets
Basic gravity flush systems

Professional Installation Recommended

Wall-mounted toilets
Smart toilets
Pressure-assisted systems

Improper installation can lead to leaks, poor flushing, or long-term damage—so when in doubt, hire a professional plumber.

Here’s a guide on What to Know When Installing a New Toilet.

Common Mistakes to Avoid When Choosing a Toilet

Even with a solid toilet buying guide, homeowners often make these mistakes:

1. Ignoring Bathroom Space

Choosing a toilet that’s too large can make your bathroom feel cramped.

2. Prioritizing Price Over Quality

Cheaper toilets often lead to more repairs and replacements.

3. Overlooking Water Efficiency

Older or inefficient models can increase your water bill significantly.

4. Skipping Professional Advice

A plumber can recommend the best option based on your home’s plumbing system.

How Hard Water Affects Your Toilet Choice

Schedule regular maintenance
