Walnut Triangle Solid Wood Wall Panels | GroovePanel®

The Panel Hub panels are built to set them apart from other wall panels:

• Easy Installation: adhesive-only installation with optional screws for added security.
• Real Wood: Many mass-market panels look repetitive. Ours has unique groove patterns and mixed natural wood tones.
• Responsibly Sourced: TPH factories only use FSC-certified wood that are sustainably sourced, backed by credible certifications.

You’ll receive your panels in reinforced cartons, packed to arrive in perfect condition. Each box includes a quick install guide to help you get started. Delivery timing and coverage per carton are listed on each product page.

Most continental U.S. orders arrive in 2-7 business days via FedEx®. Exact delivery times are shown at checkout.

You can install the panels using either method below:

• Glue Installation: Apply Loctite PL Premium 3X Construction Adhesive to the back of each panel. Press firmly onto a clean, smooth wall and hold for a few seconds to secure.
• Nail Gun Installation: Use DeWalt 2″ 18-Gauge Brad Nailer to fasten panels directly to drywall.

For both methods: We recommend cutting panels using electric saw such as the BLACK+DECKER Cordless Reciprocating Saw for a perfect fit. Prefer professional installation? Contact us and our team will see how we can help.

Each Walnut Triangle panel measures 11.8" × 11.8".

Most accent walls use 10-15 panels, depending on the wall size and layout. Measure your wall width and height to estimate your panel count, use our Box Calculator, or contact our team and we’ll calculate it for you.

Our GroovePanel® series use real solid wood panels, not printed laminate or veneer.

Each panel shows natural wood grain, variation, and texture that changes slightly from piece to piece.

The panels are designed for interior use only. For longer durability, we would not recommend the panels to be exposed to direct rain, sunlight, or outdoor humidity.

You can install on drywall, plaster, plywood/MDF, or prepared masonry. Uneven walls work fine, panel structure will adjust to minor imperfections. Make sure the surface is dry, solid, and free of dust for best result.

Yes. Panels can be trimmed with a circular saw or hand saw to fit around outlets, windows, and edges. The wood cuts cleanly and installs flush against drywall.

The geometric grooves help scatter sound reflections, which can slightly reduce echo in open rooms. They are commonly installed in:

• living rooms
• offices
• conference spaces
• media rooms

For full acoustic treatment, we recommend our SoundPanel™ collection.

Solid wood wall panels deliver lasting durability and a premium, natural look that alternatives like wallpaper or laminate can’t match. While natural wood can expand or warp over time, our panels are kiln-dried and carefully prepared to minimize movement; so you get the beauty of real wood without the worry.

Each panel has a professionally applied satin oil finish that provides even color, a soft sheen, and surface protection straight out of the box.

Solid wood wall panels typically require very little maintenance. Wipe panels with a microfiber cloth to remove dust. For marks or smudges, simply use a damp cloth, no chemicals needed.

You can return unused panels within 60 days in their original packaging. Every panel is covered by a 5-year residential and commercial warranty for peace of mind. You can read our full return policy here.
