Toilet
Buying Guide

Everything you need to know about choosing a toilet.

Understand the Possibilities

Explore all the options available to you when selecting a toilet.

Toilet Types

One of the first decisions will be what type of toilet is best for you and your bathroom space: one-piece or two-piece toilet, floor-mount or wall-hung.

Rough-In Measurement

Not all toilets are right for every bathroom, so figuring out how much space you have is a key step.

Toilet Design

Choose the shape of your toilet bowl, the height of your toilet, and more.

ContinuousClean

New technology means you can automatically flush and fight germs at the same time, keeping your bowl clean longer.

Color Options

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.

Don't Forget the Seat

Toilet seats come with a host of features, including Quick-Release™ hinges for easy cleaning, Quiet-Close™ functionality, and bidet-style cleansing.

KOHLER Collections

Your bathroom should reflect your personal design style. We have many collections, encompassing traditional, transitional, and contemporary styles.

One-Piece Toilets

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

Two-Piece Toilets

A separate tank and bowl are assembled together to create the full toilet. Two-piece toilets offer great value to homeowners.

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.

For floor-mount rough-ins, always measure from the wall, not the baseboard.

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.

Measure between the studs for wall-hung toilet rough-ins.

Bowl Shapes

The big difference in bowl shapes is length. Round-front is usually space-saving, while elongated bowls offer more comfort for most adults. The choice is yours.

Elongated Toilets

Provides extra room and comfortable seating, with bowl length between 28½" to 31⅝".

Round-Front Toilets

With the shortest bowl length of 25⅝" to 29¾", round-front toilets are a space-saving solution for small bathrooms.

Water-Saving Toilets

Reduced water consumption saves you money. Older toilets used 3.5 gallons per flush, but today our toilets can use as little as 0.8 gallons and can reduce the average family's water used by toilets by 20 to 60 percent.

WaterSense®-labeled toilets meet EPA criteria for performance and water efficiency.

Flushing

Toilet Flushing Types

Choose the one you're most comfortable with.

Single-Flush

Same consistent flush with every use, with models that range between 1.0 and 1.6 gpf. Single-flush toilets offer you the most design, shape, color, and installation options.

Dual-Flush

Dual-flush toilets offer you the choice of a light or full flush, using as little as 0.8 gallons for a light flush and up to 1.6 gallons for a full flush.

Right or Left?

The flush handle is most commonly located as a push or swing lever on the front or side of the toilet. You’ll also want to be sure that you have easy access to the handle once the toilet is installed.

Choose a flush handle position that will be easy to access.
