This comprehensive guide will walk you through the key factors to consider when selecting a new toilet, ensuring you make an informed choice that meets your needs, preferences, and budget. Let’s dive in and explore everything you need to know about choosing the perfect toilet!

Understanding Toilet Rough-In Measurements: A Critical First Step

Before you even begin browsing different toilet styles, it’s crucial to understand toilet rough-in measurements. This measurement dictates whether a new toilet will fit properly in your bathroom’s existing plumbing setup. The rough-in is the distance from the finished wall behind the toilet to the center of the floor bolts that secure the toilet to the floor. Remember to measure from the wall, not the baseboard.

The most common rough-in size is 12 inches, but 10-inch and 14-inch rough-ins are also available, typically in older homes or specific bathroom layouts. Getting this measurement right is critical. An incorrect rough-in measurement can lead to a very difficult, and potentially costly, installation.

Special Considerations for Wall-Hung Toilets

If you are considering a space-saving wall-mounted toilet, you’ll also need to understand the depth of your wall studs. This is because the in-wall water tank needs to be securely supported by the studs. These tanks come in sizes designed to coordinate with 2x4 or 2x6 studs, so ensure you choose a tank that matches your wall construction.

Choosing the Right Bowl Shape: Elongated vs. Round Toilets

The shape of your toilet bowl significantly impacts both comfort and space efficiency. You’ll generally find two main options: elongated bowls and round bowls.

Elongated Toilet Bowls

Elongated toilet bowls are longer and have an oval or egg-like shape. Many people find them more comfortable, particularly adults, due to the increased seating area. Elongated bowls are generally the preferred choice in larger bathrooms where space is not a significant concern.

Round Toilet Bowls

Round toilet bowls are smaller and more compact, making them an ideal option for smaller bathrooms, powder rooms, or any space where saving room is a priority. While they may feel slightly less comfortable for some, they are a practical and efficient choice in many situations where space is limited.

Toilet Height: Standard vs. Comfort Height Toilets

Toilet height is another important factor to consider, especially for those with mobility issues or taller individuals. You’ll generally find two main options: standard height and comfort height.

Standard Height Toilets

Standard height toilets typically measure 14 to 15 inches from the floor to the top of the bowl. This is the traditional height and works well for many people.

Comfort Height Toilets

Comfort height toilets, also known as chair-height toilets, are taller, measuring 16 to 17 inches. These toilets are becoming increasingly popular because they make sitting down and standing up easier, especially for the elderly, people with disabilities, those with joint pain, or taller members of the household. Before deciding, consider who will be using the toilet most and choose a height that best suits their needs and comfort.

Toilet Design: One-Piece, Two-Piece, and Wall-Mounted Toilets

Toilets come in various designs, each with its own set of advantages and disadvantages. Here’s a look at the most common types:

Two-Piece Toilets

Two-piece toilets are the most common type. They consist of a separate tank and bowl, which are connected during installation. Two-piece models are generally more affordable and easier to transport and install. They also offer a wider variety of styles and designs.

One-Piece Toilets

One-piece toilets have the tank and bowl integrated into a single unit. This design gives them a seamless, sleek look that can be easier to clean. One-piece toilets often cost more and can be more difficult to transport due to their single-piece construction.

Wall-Mounted Toilets

Wall-mounted toilets are mounted to the wall, with no base touching the floor. They require a drain in the wall and a thicker wall to support the weight of the tank and the toilet. They tend to cost more to purchase and install but are a great option for a modern, space-saving bathroom.

Feature Two-Piece Toilet One-Piece Toilet Wall-Mounted Toilet
Cost More Affordable More Expensive Most Expensive
Installation Easier More Difficult More Complex
Cleaning Slightly harder Easier Easier
Space Efficiency Standard Standard Most Space-Efficient
Style More Options Sleek & Modern Modern & Minimalist

Water Conservation: Choosing a Water-Efficient Toilet

Toilets can account for nearly 30% of a home’s indoor water usage, making water conservation a critical consideration when choosing a new toilet. Modern toilets use advanced flushing technology to conserve water without sacrificing performance. Look for toilets with the WaterSense label, indicating that they meet EPA standards for water efficiency. These water-efficient toilets use less water per flush, helping you save on your water bill and reduce your environmental impact. Consider dual-flush options, which allow you to choose a lower water volume for liquid waste, further increasing your water savings.

Actionable Steps: How to Choose the Right Toilet for Your Home

Now that you have a better understanding of the key factors involved in choosing a toilet, here are some actionable steps to take:

  1. Measure your current toilet’s rough-in size accurately.
  2. Determine whether an elongated or round bowl best suits your space and preferences.
  3. Consider whether a standard or comfort height toilet is right for you or your family.
  4. Decide whether a two-piece, one-piece, or wall-mounted toilet fits your design and budget.
  5. Look for water-saving models with the WaterSense label.
  6. Consider dual-flush technology for even greater water savings.

By taking these steps, you can confidently choose a toilet that meets your needs, enhances your bathroom, and reduces your water footprint.
