Quick Answer

What is Cassidy?

Cassidy is a rigid, wood-look SPC floor in a dark grey-brown shade, with a durable, heavy-traffic wear layer for a simple, carefree finish.

Is it waterproof?

Yes — 100% waterproof. A splash at the sink or a dropped glass wipes up without harming Cassidy when cleaned promptly; don't leave water standing. Indoor use only — outdoor installation is not approved.

How durable is it, and what traffic can it take?

Cassidy has a 20 mil wear layer — approximately 0.51 mm — designed for heavy residential use and many light-commercial applications, giving you excellent protection against everyday scratches, scuffs, and abrasion. That's a step above the standard-duty wear layers.

Will it hold up to daily life?

Cassidy has a 20 mil protective layer — thicker than the thin wear layers on entry-level LVT. That's the physical protective film above the print, sealed by finish.

What does the plank surface look like?

Up close, Cassidy shows a flowing, cathedral-style grain that sweeps across each plank, broken by heavy dark mineral streaking and weathered character marks. Several knots and fissures of moderate density and medium size appear across the surface, giving each board its own distinct figure rather than a repeating pattern. The result is a plank face with real visual character and plank-to-plank variation, not a look that reads as stamped or uniform.

Quiet enough upstairs or in a condo?

The acoustic layer damps the hollow "click" sound characteristic of floating floors. Cassidy is quieter underfoot than LVT with a loose pad — both for the walker and for rooms below in multi-story homes.

Is it safe for indoor air?

Yes — Cassidy carries FloorScore certification, independently tested for low chemical emissions. That matters most for households with allergies, asthma, or young children.

Will this color work in my room?

Cassidy is a neutral, medium-dark grey-brown, which keeps it useful in a range of light conditions -- it won't swing distractingly warm or cool the way a strongly undertoned color can. In a brighter room it reads as a rich charcoal-brown; in a dimmer space it reads closer to near-black. That neutral base pairs easily with most wall and trim colors, from crisp white to deeper charcoal accents, without fighting the floor for attention.

Overview

Cassidy reads as a deep smoky grey-brown, cooled by charcoal undertones rather than warmed by them -- a neutral shade that stays moody and dark rather than lifting toward beige. Its surface shows a bold, sweeping cathedral grain with visible mineral streaking, giving the surface real figure and movement rather than a flat, repetitive look. It's also waterproof and stands up to spills, so it works as well in a busy kitchen or laundry room as it does in a quiet den. That kind of bold presence suits a room built to showcase the floor -- a den, home office, hallway, or open living space -- rather than one meant to fade into the background. Right for someone who wants a floor with dramatic figure and real visual movement -- if you'd rather have a calmer, quieter grain, a shade with less pronounced streaking is the better fit.

A deep, moody grey-brown with sweeping cathedral grain and heavy mineral streaking -- built to stand out, not blend in.

Frequently asked questions

Will it match my cabinets?
Cassidy is a neutral, medium-dark grey-brown, so it tends to work with a wide range of cabinet tones rather than demanding one specific match. Pale cabinetry -- white, light grey, or soft cream -- creates clean contrast against the dark floor, while warm wood-tone cabinets play off its charcoal undertone for a richer, more grounded pairing. Because the color reads as a cool-leaning neutral rather than a warm one, it's generally forgiving with most cabinet finishes.
How does this color read in a windowless basement?
In a windowless or low-light room like a basement, a medium-dark neutral like Cassidy tends to read a touch deeper and cooler than it does in daylight, closer to a near-black charcoal than a true grey-brown. Because the color is neutral rather than warm, it doesn't turn muddy or flat under artificial light the way a strongly warm-toned floor can -- pairing it with brighter walls and adequate lighting keeps the space from feeling too dark.
