An Onyx shower combines the upscale appearance of stone with the convenience of a durable solid-surface system. The Onyx Collection manufactures made-to-order shower bases, wall panels, trim, seats, caddies, and coordinating accessories in custom sizes, shapes, and colors. This flexibility makes Onyx an excellent option for straightforward shower replacements, personalized bathroom renovations, and accessible shower designs.

Unlike traditional tile surrounds, Onyx shower walls do not require a grid of grout lines. Their smooth, nonporous surface is easier to wipe clean and gives the shower a polished, continuous appearance. With numerous colors, patterns, finishes, base styles, and accessories available, your new shower can be customized to complement your bathroom beautifully.

Replace an Aging Shower with Something Easier to Enjoy

Cracked tile, stained grout, outdated finishes, difficult cleaning, and an impractical layout can make your bathroom feel older than it is. An Onyx shower replacement can give the space a fresh appearance while reducing ongoing maintenance.

We can help replace an existing fiberglass enclosure, tiled shower, or outdated solid-surface system with custom Onyx shower walls and a coordinating base. The result is a cleaner, more cohesive space designed for your home.

A shower replacement is also an ideal opportunity to add storage, upgrade fixtures, improve lighting, incorporate a bench, or prepare the bathroom for changing mobility needs.

Bathrooms should be beautiful—but they should also be practical. Onyx shower systems are made from solid-surface materials that are durable, easy to maintain, and designed for years of everyday use.

Benefits include:

• Custom-built for your space
• Durable solid-surface construction
• Low-maintenance, easy-to-clean surfaces
• Coordinated accessories and trim
• Made in the USA
• Backed by a lifetime guarantee from the manufacturer

Replacing an old fiberglass shower or tub? Planning a complete bathroom renovation?

The Onyx Collection offers solutions for nearly every project, from simple tub-to-shower conversions to fully customized walk-in showers. Their wide range of base styles, wall panels, accessories, and shower doors allows you to create a bathroom that's both functional and beautiful.

Everyday Comfort with a Clean, Open Design

Walk-in showers can make a bathroom feel more spacious while providing easier access than many traditional tubs and high-threshold shower enclosures. Onyx shower bases are available in several threshold configurations, allowing us to recommend a design suited to your room and mobility needs.

Your walk-in shower installation can include:

• A low-profile shower base
• Custom Onyx shower walls
• Coordinating shelves or caddies
• A built-in or fold-down seat
• Strategically positioned grab bars
• A handheld showerhead
• Glass doors or an open-entry configuration
• Slip-conscious flooring and base options

If you have been searching for walk-in showers near me or professional walk-in shower installation in Troy or St. Louis, our local team is ready to help.

Create a Bathroom That Supports Greater Independence

A thoughtfully designed accessible shower can improve safety, comfort, and confidence without making your bathroom feel institutional. Onyx offers ramped-access and low-profile shower base options that can support easier entry, subject to the dimensions and construction of your bathroom.

We can personalize your barrier-free shower with a bench or seat, grab bars, accessible controls, handheld shower fixtures, practical storage, and an entry configuration suited to your needs.

Barrier-free and low-threshold are not always the same as completely curbless. The best option will depend on your subfloor, drainage, bathroom layout, and applicable building requirements. Our team will evaluate the space and explain what is practical for your home.

Replace an Unused Bathtub with a Practical Walk-In Shower

If you rarely use your bathtub, converting it into a shower can make better use of the space. A tub-to-shower conversion replaces the existing tub with a comfortable shower designed for easier entry, improved organization, and simpler cleaning.

Because Onyx shower components can be made to fit many existing openings, they are well suited to bathtub replacement projects. Choose wall panels, a coordinating base, built-in storage, seating, grab bars, and other features to create a shower tailored to your routine.

A tub-to-shower conversion may be right for you if:

• Stepping over the side of the tub has become difficult
• You want a larger or more open shower
• The existing bathtub is rarely used
• You are planning to age in place
• Your current surround is damaged or outdated
• You want to reduce grout maintenance

Onyx shower wall panels create a smooth, upscale surround with substantially fewer joints than a conventional tile installation. Panels can be paired with coordinating trim, caddies, corner details, seating, and shower bases for a unified design.

Custom Onyx surrounds are available for showers and bathtubs. They are a strong choice for homeowners who want the beauty of a stone-inspired surface without the upkeep associated with numerous grout lines.

With many colors and styles available, you can create a bright and airy retreat, a warm traditional bathroom, or a dramatic contemporary design. The Onyx Collection also provides a color selector to help homeowners explore the available possibilities. View Onyx colors.
