Wall cladding is a finished surface fixed over a wall frame or existing lining to change how a room looks, sounds and wears. Inside a home, timber, fluted panels, PVC and fibre cement are the usual choices, and installed prices vary widely by material and finish (indicative — get itemised quotes).
This guide suits owners planning a feature wall, a full room or an alfresco area. It compares materials, costs and fixing methods, and shows where DIY ends and a licensed trade is needed.
Key points
- Interior wall cladding works best as a feature wall, with real timber or fluted panels adding warmth and texture without covering every surface.
- The cheapest interior wall material is usually painted plasterboard; cladding is a style upgrade, not a budget one.
- Wet areas, kitchens and outdoor walls need materials and details that suit moisture, heat and fire rules.
- Test older fibro walls for asbestos before you drill, sand or cut, and never disturb anything suspect.
What is wall cladding?
Wall cladding is a layer of boards, panels or sheets applied over a wall. Indoors it is mostly decorative and acoustic, while outdoors it also protects the structure from weather.
You may see the same idea called cladding on wall, cladding wall, indoor cladding or interior wall linings. They all describe a surface layer you choose for look, feel and performance.
- Interior cladding: feature walls, bedrooms, living rooms, studies and entries, where appearance and sound control are the main goals.
- Exterior cladding: weatherboard-style, fibre cement or timber on the outside of a home, covered in our external cladding options guide.
- Alfresco cladding: a covered outdoor wall exposed to weather, humidity and sometimes embers.
- Fixing methods: screws or nails into battens or studs, construction adhesive, or clip systems on timber and metal.
- Finishes: raw, oiled, stained, painted or factory-finished, each with a different upkeep routine.
- Approvals: most internal cladding needs no approval, but structural changes, fire-rated walls and strata buildings have rules you should check first.
Types of wall cladding and internal wall cladding materials
The material sets your look, budget and maintenance, so decide it first.
| Type | Best for | Strength / durability | Price band |
|---|---|---|---|
| Solid timber boards (interior wood cladding) | Warm feature walls in living rooms and bedrooms | Long-lasting if kept dry, needs finishing | $$$–$$$$ |
| Fluted or slat panels (timber or MDF) | Feature walls, TV walls and bedheads | Good acoustic effect, easy to install | $$–$$$ |
| Plywood and VJ panelling | Cottage, coastal and hamptons looks | Moderate; paint or clear finish needed | $$ |
| PVC and adhesive wall panels | Laundries, garages and rentals | Moisture-resistant, less natural-looking | $–$$ |
| Fibre cement sheet or plank | Wet areas, alfresco and painted walls | Tough and stable, needs correct sealing and dust control | $$–$$$ |
| Stone-look or tile cladding | Fireplaces, entries and bathrooms | Heavy and durable, needs a suitable backing | $$$–$$$$ |

Timber wall panels
Timber panels are the most popular route for interior feature walls. Our timber wall panels guide compares profiles, finishes and installation.
Internal wood cladding ideas for living rooms and bedrooms
Timber cladding suits Australian homes with natural light and a calm palette. These ideas work in most rooms.
- Spotted gum wall cladding gives a rich, warm grain that suits living-room feature walls; check it’s from a sustainable source and seal it with a finish suited to indoor use.
- Interior wood cladding on the bedhead wall frames the bed and adds sound absorption; keep it clear of bedside lighting and power points.
- Timber interior cladding around a TV hides cables in a recessed channel; leave a gap for ventilation behind the equipment.
- Timber cladding internal in the entry makes a strong first impression and takes knocks better than paint; add a scuff-resistant finish.
- Indoor timber cladding in a study reduces echo on video calls; paint the wall behind it black or dark to make slats look deeper.
- Half-height cladding with a painted upper wall suits hallways and dining rooms, because it protects the wall where bags and chairs hit it.
Fluted wall cladding and internal cladding ideas
Fluted wall cladding uses vertical grooves to add shadow lines and texture, and it’s easy to work with when backed by a flat wall.
- Use fluted panels as a single feature wall behind a sofa or bed, so the texture stands out instead of overwhelming the room.
- Paint the panels the same colour as the wall for a quiet, tone-on-tone look that highlights the shape instead of the grain.
- Go full height from floor to ceiling for the best effect, and plan the joins around power points and switches.
- Add integrated LED strips in the recess only with a licensed electrician, since low-voltage drivers and wiring need correct installation.
- Check panel material in wet areas; MDF swells with steam, so use moisture-resistant or sealed products in bathrooms and laundries.
- Combine with plain painted walls and a good paint finish; see how our painters work on interiors through the painting service page.
Wall cladding cost
Costs depend on the material, the finish and how many cut-outs, corners and joins the wall has.
| Item | Materials only | Installed |
|---|---|---|
| Fluted MDF or slat panels | Low to mid per m² (indicative — get itemised quotes) | Mid per m² (indicative — get itemised quotes) |
| Solid timber boards, such as spotted gum | Mid to high per m² (indicative — get itemised quotes) | High per m² (indicative — get itemised quotes) |
| VJ or plywood panelling | Low to mid per m² (indicative — get itemised quotes) | Mid per m² (indicative — get itemised quotes) |
| PVC or adhesive panels | Low per m² (indicative — get itemised quotes) | Low to mid per m² (indicative — get itemised quotes) |

| Painted plasterboard lining | Lowest per m² (indicative — get itemised quotes) | Low per m² (indicative — get itemised quotes) |
- Wall prep: uneven or damp walls need straightening, battens or repairs before cladding goes on.
- Finishing: staining, oiling or painting adds labour, often as much as the install itself.
- Cut-outs: power points, switches, vents and windows add time, and moving electrical items requires a licensed electrician.
- Waste: patterned or fluted panels leave offcuts, so allow extra material to match the grain.
- Access: stairs, high ceilings and tight rooms add labour and scaffold or platform hire.
- Removal: stripping old panelling or lining adds disposal fees, and suspect fibro must be tested for asbestos first.
Cheapest interior wall material and interior wall linings
If budget is the main driver, here is how the common linings compare. Remember that cladding is a style choice, not a saving.
| Interior wall lining | Best for | Notes |
|---|---|---|
| Painted plasterboard | Most rooms; the cheapest standard option | Needs good finishing and paint to look its best |
| Moisture-resistant plasterboard | Bathrooms and laundries | Still needs correct waterproofing by a licensed waterproofer |
| Fibre cement sheet | Wet areas and garages | More robust than plasterboard; use dust controls when cutting |
| Plywood sheet | Studios, workshops and rustic looks | Visible joins; finish with paint or clear coat |
| PVC panels | Rentals and quick covers | Easy to clean but looks plastic |
| Rendered or textured finish | Modern or Mediterranean styles | Needs skilled trades for even results |
Alfresco wall cladding
An outdoor wall faces sun, rain and sometimes embers, so the product must suit exterior conditions.
- Use exterior-rated products only; interior MDF swells and fails outdoors within a season or two.
- Check bushfire requirements for your block, as some areas restrict combustible cladding near the house.
- Seal every cut edge and end grain on timber with the manufacturer’s recommended product.
- Allow for movement and ventilation behind boards so moisture can escape and boards don’t cup.
- Consider fibre cement for stable painted finishes; read our James Hardie Axon cladding guide for one popular option.
- Look at other styles such as Linea weatherboard, Scyon Matrix cladding, fake stone cladding or charred timber cladding for outdoor walls.
Pros and cons of wall cladding
| Pros | Cons |
|---|---|
| Adds texture and warmth that paint alone can’t | Costs more than painted plasterboard |
| Hides minor wall damage and uneven surfaces | Hard to remove neatly without damaging the wall |
| Slats and panels reduce echo in hard-surfaced rooms | Dust collects in grooves and needs regular cleaning |
| Can be done in stages, one wall at a time | Power points and switches need careful planning |
| Wide range of timber, paint and panel finishes | Some products swell, warp or fade if used in the wrong place |
| Can lift the look of a room before a sale | Poor installation is obvious and expensive to redo |
How to choose wall cladding
- Pick the room first: dry living areas allow timber, while wet areas need moisture-rated panels or sheets.
- Decide how much wall to cover; one feature wall costs a fraction of a whole room and often looks better.
- Check fire and heat exposure, especially near fireplaces, cooktops and heaters, and keep the manufacturer’s clearances.
- Plan the finish: raw timber, oil, stain and paint each need different upkeep, so choose one you will maintain.
- Check the wall condition for damp, cracks or old fibro before you buy anything.
- Request itemised quotes that separate materials, labour, finishing and electrical changes.
Installing wall cladding indoors
- Test old walls for asbestos if the house is older or has any fibro sheeting, and stop work if there’s any doubt.
- Find studs and services with a stud finder, and mark cables and pipes before fixing anything.
- Fix battens level and plumb, because small errors show up as gaps and uneven grooves.
- Acclimatise timber and panels in the room before fixing so they don’t shrink or swell afterwards.
- Cut with dust control for fibre cement or MDF, wearing a suitable respirator and eye protection.
- Leave a small expansion gap at edges and finish with scotia or trim.
- Use only label-approved oils and sealers, and ventilate the room while they cure.
Wall cladding FAQs
What is the cheapest interior wall material?
Painted plasterboard is usually the cheapest standard interior wall lining. Sheet products such as plywood and PVC panels cost more, and solid timber cladding costs the most. If budget matters, use cladding on one feature wall and keep the rest of the room painted plasterboard.
Can you put cladding over existing walls?
Often yes, if the wall is dry, sound and free of asbestos. Fix battens to the studs, level them and add the cladding on top. Uneven or damp walls need repairs first, and older fibro sheeting must be tested before you drill into it.
Is timber cladding suitable for bathrooms?
It’s risky. Steam and splashes cause solid timber to swell, stain and grow mould, and unsealed MDF fails quickly. If you want a timber look in a wet room, use sealed, moisture-rated products away from direct water, and have any waterproofing done by a licensed waterproofer.
What is fluted wall cladding made of?
Fluted wall cladding is usually made from timber, MDF, plywood or PVC, with vertical grooves cut or moulded into the face. Solid timber and veneered panels give the best finish. Check the moisture rating and the fixing method before you buy, and paint or seal it to suit the room.
Do I need approval to add internal wall cladding?
Usually not for decorative cladding in a house. You may need approval if you change structure, fire-rated walls or common property in a strata building. Check with your council, certifier or strata manager before you start, and keep proof of any licensed trade work.
Can you paint wall cladding?
Yes. Most timber, MDF and fibre cement cladding can be primed and painted. Use the primer and paint the manufacturer recommends, fill nail holes and caulk joins first, and sand lightly between coats. Painted fluted panels give a quiet, tone-on-tone look that suits modern interiors.
