How to Choose a Toilet

Making the highest-performing and most innovative toilets is always top of mind for us, because we believe the people who buy them shouldn’t have to give them a second thought. Let us help you find the right toilet for your space.

Getting Started

Choosing a toilet will require that you consider your needs and desires in order to identify the toilet best-suited to your requirements and to the reality of your bathroom. This toilet buying guide will help you do that. 
To begin, consider these questions:
1. What type of bathroom will your toilet serve? You might choose different functionality for different bathrooms, like cleansing or bidet functionality for a master bath but easy-to-clean designs for a kids' bath.
2. Are you replacing a toilet or are you remodeling an entire bathroom? For a replacement toilet, you may want to choose the same footprint so it fits the space exactly, without gaps or visible marks on the floor.
3. Who will be using this toilet and do they have special needs? For example, you might consider taller than average toilets if someone in your home has difficulty sitting or standing or if you are updating your toilet in anticipation of future needs.
4. Have you considered a toilet with bidet functionality? Toilets that offer personalized cleansing are redefining the way people think about their private rituals.
5. How would you describe the style of your bathroom? Toilets come in many styles and colors, so you can either match or complement your existing bathroom's design details.

Color is important and plays a vital role in the look and feel of your bathroom. The decision of a white or color toilet can shift the tone and enhance the style by creating a drastic contrast or seamless integration. There is no wrong answer when choosing a color, it’s simply a matter of choice.

Toilet types are defined by how many pieces make up the toilet (one-piece or two-piece) and how it's installed (on the floor or on the wall).

One-Piece Toilets

The tank and bowl are cast as a single piece, meaning the toilet is seamless and easy to clean.

Floor-Mount Rough-In

To ensure your floor-mount toilet fits your space, measure from the wall (not the baseboard) to the floor bolts that attach the toilet to the floor. This is the rough-in measurement. The most common rough-in is 12", though there are also 10" and 14" rough-ins.

12" Rough-In 14" Rough-In

Wall-Hung Rough-In

To ensure your wall-hung toilet fits your space, measure the depth of the wall studs which will hold the in-wall water tank.

These tanks come in sizes that coordinate with 2" x 6" or 2" x 4" studs. You will need to choose a tank that matches.
