Quick answer: A hardware kit cost breakdown for a pine plywood cat build splits into fixings, structural brackets, wall anchors, sisal fixings and finishing supplies. Fixings and brackets are the core spend; anchors matter if the piece is tall; finishes are optional. Buy assorted screws and a drill bit set once, then restock only what each build uses, and price items locally before you start.
Plywood and timber get most of the attention in a cat furniture budget, but hardware can quietly add up: screws in three lengths, brackets, washers, anchors, sanding sheets and a pot of finish. Planning the hardware kit before buying stops repeat trips to the shop.
This guide breaks down a typical kit for a dining nook build in pine plywood, such as a low bench with a sisal panel or a small climbing frame beside the table. For the full beginner tool list, see our beginner's tool kit guide.
What Goes Into a Hardware Kit Cost Breakdown
Prices vary a great deal by country, shop and pack size, so this guide focuses on what to buy and how much of it rather than exact prices. Use the list to build a shopping list, then price it at your local hardware store.
| Category | Typical items | Buy once or per build? | Notes |
|---|---|---|---|
| Fixings | Wood screws in short, medium and long lengths; washers | Assorted box once, restock lengths you use | The biggest single cost for most builds |
| Brackets | Steel angle brackets, corner braces | Per build | Strengthen joints that take a cat's weight |
| Wall anchors | Anchor straps, stud screws | Per build | Essential for tall or narrow pieces |
| Sisal fixings | Small screws, washers or staples set flush | Per build | Keep heads below the surface |
| Abrasives | Sanding sheets in two grits | Pack once | Plywood edges need extra sanding |
| Finish | Water-based, low-odour finish (optional) | Tin lasts several builds | Never on the sisal |
| Drill bits | Pilot and countersink bits | Once | Prevents plywood splitting |
Fixings: Where the Money Goes
Screws are cheap individually but add up when you need three lengths. Plywood edges split easily, so drill pilot holes and countersink every screw so the head sits flush or slightly below the surface. That keeps claws from catching.
Buy an assorted box of wood screws once rather than small packs for each build. Note which lengths run out first and restock only those. Washers under screw heads spread the load and help hold sisal ends.
Brackets and Joints
Joints that carry a jumping cat need more than screws into plywood edges. Steel angle brackets or corner braces inside the frame, out of sight, add a lot of strength for a small cost.
Our guide to an IKEA hack cat tree for a dining nook in pine plywood shows where brackets matter most in a nook layout. For a full cost list on a similar build, see our IKEA hack cat tree cost breakdown.

Wall Anchors for Tall Pieces
A dining nook build is often narrow and tall to fit the space, which makes it more likely to tip. An anchor strap screwed into a wall stud is the cheapest safety upgrade in the kit.
Our safety checklist for anchoring a tall DIY cat tower explains how to find studs and fit straps properly. Include anchors in the budget from the start rather than adding them later.
Sisal and Scratch Surfaces
If the build includes a scratch panel, plan the fixings for it. Ohio State's Indoor Pet Initiative advises that vertical scratching posts should be tall enough for your cat to stretch up to scratch, and notes that cats often scratch objects near sleeping areas and room entrances. A dining nook is often on a route between rooms, which makes it a good place for a scratch surface.
International Cat Care notes that some cats prefer vertical and others horizontal surfaces. Watch your cat before deciding which way to fit the panel. Fix sisal rope or sisal fabric at the ends with small screws and washers, set below the surface, and avoid staples that can work loose.
Finishes and Indoor Air
Pine plywood can be left unfinished, which saves money and avoids fumes. If you want a finish on the frame for wipe-clean surfaces, choose a water-based, low-odour product and keep it off the sisal.
The EPA notes that paints, varnishes and wax all contain organic solvents, and recommends increasing ventilation when using products that emit volatile organic compounds. Finish the piece in a well-aired space, let it cure fully, and keep the cat away until it no longer smells.

Plywood Choices That Affect Hardware
Thicker plywood holds screws better and needs fewer brackets. Thin sheets save money on wood but may need extra bracing, which adds to the hardware bill. For most cat furniture, a sturdy grade of pine plywood strikes a good balance between cost, weight and strength.

Tools You May Already Own
Hardware is only part of the cost. A drill and driver, a tape measure, a square, clamps and a saw are needed for most plywood builds. If you do not own them, borrowing from a neighbour or using a tool library can save a lot, and many hardware shops will cut plywood sheets to size for a small fee or free, which also makes the parts easier to carry home.
A countersink bit is worth buying even for a single build. It lets screw heads sit below the surface so they cannot snag claws or catch children's clothes, and it reduces splitting at plywood edges.
Fitting the Piece Into a Dining Nook
Dining nooks bring their own constraints. Chairs slide in and out, people walk past with plates, and the floor may be tiled or wooden. Measure the nook with chairs in their normal positions so the cat piece does not block a seat or a walkway.
Felt pads under the base protect the floor, but they can also make a piece slide when a cat jumps off. A rubber grip pad or a wall anchor solves that. Keep the scratch panel on the side facing the room rather than the wall, so the cat can reach it easily.
- Leave room for chairs to pull out fully
- Keep the piece clear of radiators and heating vents
- Avoid placing it where the cat could jump onto the dining table
- Choose rounded corners at hip height
- Check the floor is level before anchoring
A nook piece used daily will need checking more often than a tree in a quiet corner. Press on each platform once a month and tighten any screw that has worked loose.
Building Your Shopping List
- Sketch the build and count every joint.
- Decide which joints need brackets as well as screws.
- List screw lengths by the thickness of the parts being joined.
- Add anchors if the piece is taller than it is wide.
- Add sisal fixings and abrasives.
- Decide whether to finish, and if so, choose a water-based product.
- Price the list locally and add a small margin for spares.
Keep receipts and a note of what you used. After one or two builds you will know your real hardware cost per project, which makes budgeting the next one easier.
Hardware Kit Cost FAQs
What hardware do I need for a plywood cat furniture build?
Most builds need wood screws in a few lengths, washers, steel angle brackets for load-bearing joints, wall anchor straps for tall pieces, small screws to fix sisal, sanding sheets and pilot and countersink drill bits. A water-based finish is optional. Count your joints first so you buy the right amounts.
How can I keep hardware costs down?
Buy an assorted box of screws and a drill bit set once, then restock only the lengths you use. Use thicker plywood so you need fewer brackets, leave pine unfinished if you are happy with the look, and plan anchors from the start so you do not make extra trips.
Do I need wall anchors for a dining nook cat build?
If the piece is taller than it is wide, or narrow to fit a nook, an anchor strap into a wall stud is a cheap and important safety step. It stops the piece tipping when a cat jumps on or off. Include anchors in your budget from the start rather than adding them later.
Is it safe to finish plywood cat furniture?
It can be, if you choose a water-based, low-odour finish, apply it only to the frame and never to the sisal, ventilate well and let it cure fully. The EPA notes paints and varnishes contain organic solvents, so keep the cat away until the piece no longer smells.
