The Materials Behind Every Bathworks Bathroom
Most bath companies install thin acrylic shells. We build in Onyx cultured stone, real crushed stone bonded with resin, made in the USA and backed by a lifetime warranty, with Kohler fixtures and quality components throughout.
Real stone, cast for your exact bathroom
Onyx isn't a brand of plastic. It's cultured stone crushed natural stone bonded with resin, cast into shower walls, pans, seats, trim, and vanity tops built for your exact space.
- Solid all the way through, the color and material run through the entire piece, not a surface coating
- Made in the USA by The Onyx Collection, a Kansas manufacturer with roughly 80 years of history behind it
- Shower pans weigh 150–200 lbs, thick, solid cultured stone, no painted foam pans
- Antimicrobial agents in the pans and walls inhibit bacteria, mold, mildew, fungus, and algae
- Industry-leading anti-slip coating on every shower pan
Onyx cultured stone vs. an acrylic shell
Both look fine in photos. Hold a sample of each in your hands and the difference is obvious in about three seconds.
Onyx cultured stone, what we install
- Real crushed stone bonded with resin, solid all the way through
- Shower pans weigh 150–200 lbs, with color and material running through the whole pan
- Zero grout lines, never needs resealing
- Custom-built to your space, walls, pans, seats, trim, and matching vanity tops
- Lifetime warranty on the material from the manufacturer
Acrylic shells, what most bath companies install
- A thin plastic liner, often glued over the old tub or surround
- Light enough to pick up with one hand, the color is a surface layer
- Looks similar in a brochure, the difference shows up when you touch it, and years down the road
That's why we bring real samples of both to your free consultation, so you can judge with your own hands, not our marketing.
Over 60 colors, 75 standard base sizes, or fully custom

And because we're full bathroom remodelers, tile, solid-surface panels, flooring, painting, electrical, mirrors, cabinets, windows, doors, and bathtubs, the materials conversation covers your whole bathroom, not just the wet area.
The stone itself is warranted for life
Onyx cultured stone carries a lifetime warranty on the material from the manufacturer, not a 5- or 10-year limited warranty that quietly expires.
- Covers the Onyx material we install, walls, pans, seats, trim, and vanity tops
- Backed by The Onyx Collection, the American manufacturer that makes every piece
- One more reason we'd rather show you a sample than a sales pitch, the material earns the confidence

The best part of Onyx might be everything you stop doing after it's installed.
- Zero grout lines large solid panels mean there's simply no grout to scrub, bleach, or re-whiten
- Never needs resealing no annual maintenance ritual, ever
- Antimicrobial by design agents infused in the pans and walls inhibit bacteria, mold, mildew, fungus, and algae
