Quick Answer
What is American Walnut?
American Walnut is a warm dark brown with a deep chocolate body and rich espresso depth, the darkest and boldest shade in the eTERRA White range. Its character comes from bold flowing grain: strong ribbon striping, dark grain streaks, and a sweeping flame figure that moves across each plank, with only the occasional small knot. The look is rich and grounded, a wood-look print over a stone-polymer core rather than a real plank.
Is it waterproof?
Yes — 100% waterproof. Powder-room splashes, daily wet feet, and towel drops wipe up without harm when cleaned promptly. Indoor use only — not for installation inside showers or wet rooms, and outdoor installation is not approved.
Will it hold up to daily life?
Kitchen stress test: dropped cutlery, pans slid from oven to counter, refrigerator casters, and dishwasher spray — American Walnut's 20 mil wear layer and UV-cured ceramic bead (EnduraPro) finish handle the spills, dropped pots, and dragged stools of daily kitchen use, and wipe clean with a pH-neutral cleaner.
What does the plank surface look like?
The plank surface is a smooth printed wood-look pattern with bold flowing grain. You see strong ribbon striping, dark grain streaks, and a sweeping flame figure, with the occasional small character knot scattered sparsely across the boards. The print sits over a 20 mil wear layer and a UV-cured ceramic-bead finish, so the surface stays consistent and resists scratches and stains underfoot.
Quiet enough upstairs or in a condo?
There's no separate underlayment to buy and no pad to choose. American Walnut's factory-attached IXPE antimicrobial sound-deadening acoustic pad comes bonded to every plank and dampens footfall noise throughout the home — one less material decision and one less install step.
Is it safe for indoor air?
Yes — American Walnut is FloorScore, GREENGUARD Gold certified, independently tested for low chemical emissions. That matters most for households with allergies, asthma, or young children.
Will this color work in my room?
American Walnut reads as a deep, saturated espresso brown that suits style-forward rooms wanting a dramatic dark floor. Because it is the darkest shade in the range, it works best where you want the floor to sit back as a strong backdrop and let lighter walls, trim, and bright accent colors stand out against it. In a room with good natural light it shows off its ribbon figure and warm undertone; in a darker space it leans toward a deep, even brown.
Price range?
Material cost: $3 to $4 per square foot. Installation is separately quoted by your flooring contractor — Kapriz refers vetted licensed pros. Plus CA sales tax. Trade pricing for American Walnut and full catalog available for contractors, designers, architects.
Overview
American Walnut is the darkest shade Gaia Floors offers in the eTERRA White line, a deep chocolate brown with rich espresso depth. The plank reads as a confident dark floor, with bold flowing grain, strong ribbon striping, dark grain streaks, and sweeping flame figure across a smooth printed surface; the occasional small character knot keeps it from looking flat. This is a wood-look print over a stone-polymer core, so American Walnut gives you that bold dark look without the upkeep of a real plank. It is built on a rigid stone polymer composite (SPC) core for dimensional stability, protected by a 20 mil wear layer, and topped with a UV-cured ceramic-bead finish that resists scratches and stains, so it stands up to daily life in a busy living room, family room, dining room, or home office. For style-forward rooms that want a dramatic dark floor as a backdrop for color, American Walnut is a strong choice.
The darkest shade in the eTERRA White range -- a deep chocolate brown with espresso depth and bold flowing grain.

Installation
American Walnut's manufacturer installation specifications. Care follows in its own section.
Installation method
These planks install as a glueless floating floor and may be laid over most existing clean, dry, level hard-surface coverings. For indoor, climate-controlled use only; not suitable for sun-rooms, solariums, showers, saunas, seasonal porches, RVs, boats, or any space with flooding potential. Acclimate the planks a minimum of about 12 hours on site before installation. Maintain a 1/4" expansion gap to walls and fixed construction such as pillars, cabinets, and islands. Install T-moldings in doorways 4 ft or narrower and in rooms 49 ft or longer in any direction. The acoustic pad is attached to the plank, so no additional underlayment should be added. Inspect every plank under good lighting before installation and discard pieces with questionable color, finish, or sheen; report visual defects within 15 days. Purchase about 5% extra material for back stock and future replacements.
Climate & humidity
Install in conditions of 35-55% relative humidity and a room temperature of 60-80°F, and keep three-season rooms within that range year-round.
Subfloor flatness & prep
The sub-floor must be flat within 3/16" over 10 ft (or 1/8" over 6 ft) and securely anchored. Concrete sub-floors must be ASTM F710 compliant, at least 3,000 psi in density, with a pH of 9 or below.
Moisture testing
Concrete must test at no more than 80% relative humidity (ASTM F2170) and no more than 3 lbs/1000 sq ft/24 hr (ASTM F1869). New concrete or gypcrete must cure and dry a minimum of 4 weeks before installation. A vapor barrier is required over all concrete sub-floors: 6 mil polyethylene with an 8" overlap.
Radiant heat compatibility
Compatible with radiant heat as long as the floor surface temperature never exceeds 80°F (26.67°C). Keep at least 1/2" of separation between heating elements and the flooring, and an in-floor temperature sensor is recommended. Raise or lower radiant heat gradually, about 10°F per day, and never shut it off abruptly.
Care & maintenance
Keeping American Walnut looking its best takes very little — the manufacturer care guidance is below.
Daily maintenance
Vacuum or sweep regularly to remove grit, but do not use vacuums with beater bars or power rotary brush heads. Clean spills quickly with a luxury vinyl cleaner and a clean white cloth, mopping back-and-forth and replacing the mop cover when soiled. Use a pH-neutral cleaner; no waxing is required. Avoid steam cleaners, spray cleaners, and any device that sprays liquid directly on the floor, as water can cause damage. Never use oil soaps, wax, liquid detergent, or other household products, and avoid excessive wet mopping and standing water. Place exterior and interior entry mats at all entrances, but avoid rubber-backed mats, which can stain the floor or trap moisture.
Furniture protection
Use felt or plastic floor protectors at least 1" in diameter under furniture legs. Chairs with wheeled casters need flat 1"-wide casters and a protective rigid mat; rubber casters are preferred over plastic or metal. Use a dolly to move heavy furniture or appliances; never slide or roll heavy items across the floor.
Pets & claws
Trim pets' nails and inspect footwear for spiked heels to protect the finish.
Climate & humidity
Minimize direct sunlight and intense lighting by keeping window treatments closed when sunlight is strong.
Radiant
Use caution with area rugs over radiant heating, as they can raise the floor temperature beyond recommended levels.
UV exposure (rooms with many windows)
Sustained direct sun can fade any hard-surface floor over time, so high-exposure rooms benefit from a window treatment.
Pro tip: In south-facing or many-window rooms, light-filtering window film or shades cut the UV reaching the floor and protect nearby furniture and area rugs at the same time.
Frequently asked questions
How do I estimate how much flooring I need?
Pro tip: don't return extras after install — colors can shift slightly between production runs. If you need 5 replacement planks in 2 years, your only exact match is the stock you kept. Bring floor-plan dimensions into the showroom and our staff will walk through the calculation with you.
Can I install SPC myself?
Most common case: DIY is allowed, but install mistakes (missed expansion gap, bad subfloor prep, wrong stagger, skipped moisture barrier) void that portion of coverage. Material defects from the manufacturer remain covered.
A few brands go further — their warranty requires "professional installation by a licensed contractor" as a coverage condition, so any DIY = warranty void even without mistakes. Check your brand's warranty language before deciding.
Pro tip: when a claim is filed, the manufacturer sends a licensed flooring inspector. DIY that followed manufacturer spec to the letter passes inspection; DIY that cut corners won't. We recommend: price out a licensed contractor quote first, read your warranty carefully, and decide based on your comfort with the procedure — not just labor savings.
Will it work in my basement?
Layer 1 — concrete moisture epoxy applied directly to the slab (manufacturer-approved liquid-applied membrane). Reduces vapor transmission well below the slab moisture limit this floor requires (measured per ASTM F1869 — see the Installation section for the exact figure).
Layer 2 — 6-mil polyethylene sheeting on the cured epoxy. The epoxy resists normal slab conditions; the plastic above is insurance against slab cracks from settling or seismic movement (common in older Bay Area homes built on fill). If the slab cracks in year 12, the plastic stops moisture before it reaches your SPC.
Cost: $600-1,100 for a typical basement vs $50-100 for plastic alone. For a floor lasting 20+ years in a moisture-prone slab, double protection pays for itself the first time the slab shifts.
How does SPC compare to real hardwood?
A genuine hardwood investment means solid hardwood, or engineered hardwood with 3mm+ veneer. That veneer thickness is the threshold where the floor becomes refinishable (2-3 refinishes over 50+ years, updated stain colors as trends shift). Appraisers factor genuine hardwood into home value; they don't factor SPC.
Caveat: budget engineered hardwood with 1-2mm veneer shares SPC's non-refinishable, 20-25 year practical life — but unlike SPC it is not waterproof, and unlike genuine hardwood with a 3mm+ veneer it cannot be refinished, so SPC stays the better pick for kitchens, baths, and basements. If you're paying hardwood prices, verify the veneer spec. Kapriz carries both categories; the right choice depends on your rooms and refinishing expectations.

How fast does it ship?
What's your return policy?
Defective products are Kapriz's problem, not yours — manufacturing defects, wrong product, or transit damage documented on the delivery receipt all get free replacement or refund. Note any visible damage on the receipt before the driver leaves.
Why returns aren't standard: reverse logistics on a flooring pallet runs $300–800 with damage risk Kapriz absorbs.
Written exceptions (rare): 25% restocking fee + customer pays freight. Opened cartons, custom orders, and discontinued runs are never eligible.
