Getting Started

In order to identify the bath best suited to your requirements and the dimensions of your bathroom, consider the following:

1. What is your project scope — a simple refresh or full remodel? Are there space or plumbing constraints?

2. Who will use the bath? How will the bath be used? Consider mobility needs and children or pets when selecting key features.

3. Check in with your project team to ensure you understand any requirements and constraints in terms of bath weight (both empty and full) as well as water heater capacity.

Understand the Possibilities

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

Installation

Before beginning your design journey, consider your space. Existing walls and plumbing may dictate the size and style of bath that can be installed.

Design

Consider the style of your bathroom as you think about bath shape, style, material, and color.

Bath Drains

Kohler offers a variety of overflow drains that are compatible with your bath selection.

ADA-Compliant Baths

We have baths available in a variety of styles and colors that meet the Americans with Disabilities Act standards.

Bath Style

Baths are defined by installation. A drop-in bath is unfinished because its exterior is hidden, while a freestanding bath has a finished exterior.

Drop-In Baths

These are designed for drop-in installation. A self-rimming edge rests on the deck material that surrounds your whirlpool or bath. A kit can modify them for under-mount installation.

Alcove Baths

Designed for walls on three sides, alcove baths are ideal for tub and shower combos. The often include an integrated apron to complete the design.

Undermount Baths

Undermount baths create a separate, personalized bathing space with a clean, contemporary look. The bath is mounted beneath a deck. Most undermount baths can accommodate a drop-in installation.

Freestanding Baths

Typically finished and accessible from all sides, the freestanding bath highlights your bathroom design. This installation option is ideal when the bath is the focal point of the room.

Corner Baths

A corner bath is usually five-sided, with a clover-shaped bathing well, and is designed to accommodate two bathers at once.

Walk-In Baths

Designed to accommodate bathers who may not be able to step over a standard bath threshold, a walk-in bath has a side door with a low threshold for entry.

Water Depth

Bath height is measured from the floor to the top edge of the bath. Depth is measured on the inside of the bath from the base to the overflow drain. Depth, length, and width determine the bath's water volume. Be sure your floor can support the weight of the full bath and that your water heater will provide enough hot water to fill it.

Depth, length, and width determine a bath's water volume.

Bath Shapes

Whatever their shape, baths are designed for comfortable soaking. Details like integrated arm rests and lumbar support let you recline with ease.

Rectangular Baths

Rectangle is the most common bath shape because it lets you stretch out and immerse in the water.

Oval Baths

An oval bath features the ergonomic support and comfort of a rectangular bath with a softer, more organic design. If you prefer an oval bath but have an alcove, there are bath options that pair an overall rectangular shape with an oval bathing well.

Corner Baths

Designed specifically to accommodate corner spaces and two bathers, this shape lets you choose between a reclined or seated bathing position.

Materials

Whether you want an easy-to-clean surface like acrylic, the unique textures of Lithocast^® cast acrylic, or durable enameled cast iron, our designs fit any bathroom.

Enameled Cast Iron

Enameled cast iron baths have a rich color and glossy finish. Our enameled cast iron baths feature an extra-thick, highly durable enamel. The cast iron is also partially made from recycled iron.

Acrylic

A strong, flex-resistant material, acrylic has a smooth finish that resists chipping and cracking for years of performance and is easy to clean.

Lithocast^®

Our Lithocast cast acrylic is a premium solid-surface material that allows for unique bath textures and designs.

Color

The color you choose for your bath helps create the look and feel of your bathroom and helps inform the tone of the room. There’s no wrong answer. Choose the color that helps create the mood you’re after. Baths come in an array of rich colors that align with your style and can be matched to other fixtures.

Hydrotherapies

Hydrotherapies combine air or sound to provide an immersive experience and harness water's natural ability to soothe the body and enhance wellness.
