Garnet — 4.5mm SPC Waterproof Flooring (GemCore Flooring)

Garnet is GemCore’s thinnest-profile SPC line — a 4.5mm stone-composite plank, the thinnest in the brand’s SPC range, with a 20-mil wear layer and a pre-attached 1mm EVA pad. Its 7″ × 48″ board carries a subtle kissed-bevel edge and clicks together as a floating floor. The 5-color range runs light-to-medium beige and brown, with one rustic multi-tone shade. Garnet is FloorScore certified and carries a warranty up to Lifetime Residential. Order any Garnet color through our Santa Clara showroom.

Colors in the Garnet collection

Garnet’s 5 colors keep close to a light-to-medium beige and brown palette — Bantry and Kenmare are the lighter, more neutral options, Shannon and Rodeen run a shade warmer and deeper, and Tralee stands apart as a rustic, multi-tone brown for a room that wants more visual movement.

Best uses for Garnet

  • Multi-unit or large-scale SPC projects — Garnet’s slimmer 4.5mm profile keeps the same 20-mil wear layer as most of the brand’s SPC lines in a thinner plank.
  • Kitchens & baths — the waterproof stone-composite core and pre-attached pad handle spills without extra underlayment.
  • Rental properties & flips — a thinner SPC plank clicks together quickly and keeps material cost down across multiple units.
  • Busy households with kids or pets — a dry-sweep-and-damp-mop routine keeps grit from abrading the wear layer.
  • Basements & below-grade rooms — the stone-composite core resists the humidity swings that affect solid wood; follow the install guide’s moisture-barrier requirement.

Choosing a color from the Garnet collection

Bantry and Kenmare’s lighter beige tones open up a smaller room or one with limited natural light, while Shannon and Rodeen’s deeper brown carries better in a sunlit space without washing out. Tralee’s rustic multi-tone pattern is a good fit for a busy room where hiding everyday wear and variation matters more than a uniform look. Order a sample or visit our Santa Clara showroom to check the color under your own lighting — dye lots can shift slightly between production runs.

Frequently asked questions about the Garnet collection

Is Garnet as durable as GemCore’s other SPC lines despite being thinner?
Garnet’s 4.5mm core is thinner than Crystal, Jasper, Opal, and Sapphire (5mm) or Diamond (6.5mm), but it carries the same 20-mil wear layer as most of the brand’s SPC lines, so surface durability is comparable — the difference is mainly underfoot feel and overall plank rigidity.
Do I need a separate underlayment for Garnet?
No — Garnet ships with a 1mm EVA pad pre-attached to each plank, so no additional underlayment is required for a floating install.
Is Garnet waterproof for a bathroom install?
Yes — Garnet’s stone-composite core is waterproof, so it holds up to shower spray and sink splashes as long as standing water is wiped up rather than left to sit.
How much Garnet do I need to order?
Each carton covers 26.29 sq ft. Measure your room and add a standard overage for cuts and waste before ordering.
