Tongue and groove panelling is one of the oldest and most reliable ways to clad a wall, and it is enjoying a real revival in bathrooms and cloakrooms. Fitted from floor to ceiling, it turns a plain, cold, tiled or painted room into a warm, characterful space that feels finished and thoughtfully designed. For homes across Nottingham and the surrounding areas, it is a practical way to add personality to small rooms that often get overlooked.
At Craig Smith Joinery, we have spent 30 years building and fitting bespoke woodwork in Nottinghamshire. Every tongue and groove project we take on is made to measure, so the boards are cut and fitted around your actual walls, fittings and pipework rather than forced into a generic kit. This guide explains what tongue and groove panelling is, why full height cladding works so well in bathrooms and cloakrooms, how to handle moisture properly, and what to expect on cost.

What Is Tongue and Groove Panelling?
Tongue and groove panelling is made from long, narrow boards. Each board has a raised edge, called the tongue, along one side and a matching slot, called the groove, along the other. The tongue of one board slides neatly into the groove of the next, locking the boards into one continuous surface.
This simple joint gives several benefits:
- A tight, even fit with no visible gaps between boards
- A strong, stable surface fixed securely to the wall
- Fixings that can be hidden for a clean finish
- Room for the timber to move slightly with changes in temperature and humidity
- A classic vertical line that makes walls look taller
Because the boards run in straight lines, tongue and groove suits both traditional and contemporary rooms. Painted in a bold colour, it feels modern. Painted in a soft neutral, it feels calm and timeless.
Why It Works in Bathrooms and Cloakrooms
Bathrooms and cloakrooms are usually small, and small rooms can feel cold and clinical. Full height cladding changes that quickly.
| Benefit | What It Does |
| Warmth | Softens hard surfaces like tiles and sanitaryware |
| Character | Adds a classic cottage or boutique hotel feel |
| Protection | Shields walls from knocks, splashes and scuffs |
| A smoother look | Hides uneven plaster and tired walls |
| A sense of space | Vertical lines draw the eye upward and make low ceilings feel higher |
| Easy updating | Can be repainted whenever you want a new colour |
Cloakrooms in particular benefit. They are often tiny, with little natural light, and a deep, rich colour on full height panelling turns them into small, memorable spaces that guests remember.
Why Choose Full Height Cladding?
| Height | Look | Best For |
| Dado height | Traditional, protects the lower wall | Hallways and larger rooms |
| Half or two thirds height | Balanced, with a painted wall above | Bedrooms and living rooms |
| Full height | Immersive, cohesive, no separate wall finish | Bathrooms, cloakrooms and small rooms |
In a small room, a full height finish has clear advantages:
- No awkward join between panelling and painted wall to maintain
- The whole room feels unified rather than split in two
- Maximum protection against splashes and knocks
- One consistent colour makes a compact room feel larger

Why a Made-to-Measure Fit Matters
Bathrooms and cloakrooms are some of the hardest rooms to panel well. They are full of obstacles, and the walls are rarely straight. A generic kit simply cannot cope. A bespoke approach solves:
- Basins, toilets and cisterns that need precise cut-outs
- Pipework, valves and radiator brackets that boards must work around
- Window reveals and door frames that need tidy edges
- Walls that lean, bow or run out of square, particularly in older Nottingham homes
- Ceilings that are not level, which show badly if boards follow a straight line
- Boxed-in pipes and awkward alcoves
We measure the room, plan the board layout and cut every board to fit. Where walls are uneven, we scribe the edges so the boards follow the true shape of the room, leaving no gaps and no need for heavy filling.
Moisture: What You Need to Know
Timber and water need careful handling, so it is worth being honest about what tongue and groove can and cannot do in a bathroom. With the right preparation and finish, it performs very well. Without it, it will not.
| Works Well | Take More Care |
| Cloakrooms and downstairs toilets | Inside shower enclosures |
| Bathrooms with good ventilation | Directly around baths with constant water contact |
| Walls around basins and behind toilets | Rooms with poor or no ventilation |
| Walls away from direct shower spray | Areas with heavy condensation and no extractor |
| Lower and mid walls in family bathrooms |
In the wetter areas, a waterproof surface such as tiles is usually the better choice. Many of our clients combine the two, tiling the shower area and cladding the rest of the room.
Moisture Protection Checklist
| Measure | Why It Matters |
| Moisture-resistant boards or properly sealed timber | Reduces swelling and warping |
| Primer and paint on every face, including edges and backs | Seals the boards against damp |
| Quality bathroom or moisture-resistant paint | Resists humidity and wipes clean |
| Sealed gaps around fittings and floors | Stops water creeping behind boards |
| A working extractor fan | Removes steam before it settles |
| Ventilation behind the boards where needed | Allows the wall to breathe |
Choosing the Right Material
| Material | Strengths | Consider |
| Solid timber | Real character, strong, paintable or stainable | Needs proper sealing, may move with humidity |
| Moisture-resistant MDF | Very smooth painted finish, stable, cost-effective | Painted finishes only, must be fully sealed |
| Treated or engineered boards | Better resistance to damp | May have a different look and cost |
For a painted bathroom or cloakroom, moisture-resistant MDF is popular because it gives a very smooth finish and stays stable. For a natural stained finish, solid timber is the better choice. Our timber joinery guide explains how different timbers behave.
Profiles and Styles
The board profile has a big effect on the look of the room.
| Profile | Look | Suits |
| Plain or flat boards | Clean, simple, modern | Contemporary bathrooms and cloakrooms |
| Beaded boards | Small rounded detail, traditional | Cottage, period and country styles |
| V-groove boards | Crisp V-shaped line at each joint | Classic and nautical looks |
| Wider boards | Fewer lines, calmer look | Larger rooms and modern schemes |
| Narrow boards | Busier, more texture | Small rooms wanting character |
Planning a Full Height Layout
Good cladding looks effortless, but it is built on careful planning:
- Starting point: we work out from a focal point, such as the centre of the basin wall or a window, so boards look balanced and no thin board is left at a corner
- Corners: a neat butt joint with a corner trim is common, while an internal mitre gives a very clean line
- Ceiling line: boards can finish with a small trim or cornice, and where the ceiling is not level we scribe the top edge so the line looks straight
- Floor line: boards can sit behind a skirting board, or the skirting can be built into the cladding, so the base is tidy and easy to clean
Working Around Fittings
Bathrooms and cloakrooms are packed with fixtures. Planning around them at the start separates a neat result from an awkward one.
| Obstacle | How We Handle It |
| Basin and taps | Boards cut neatly around pipes and fixings, with sealant for a tidy finish |
| Toilet and cistern | Precise cut-outs, with boards fitted behind fittings where possible |
| Radiators and towel rails | Brackets and pipes marked early, boards cut to fit |
| Windows | Reveals lined neatly so boards finish cleanly |
| Door frames | Boards meet the frame with tidy trim or architrave |
| Sockets and switches | Positions marked, boards cut around them |
| Boxed-in pipes | Boards fitted around or over the boxing |
| Access panels | Made removable so you can still reach stopcocks and valves |
How Installation Works
- Consultation and measuring. We visit your home, talk through the look you want and measure every wall. We check how straight and level the walls and ceiling are and note every fitting.
- Material and design choices. We agree the material, profile, width and finish, and plan how boards will meet corners, windows and doors.
- Wall preparation. The wall is checked for damp and prepared so boards can be fixed securely. Where walls are uneven, battens create a flat, solid surface.
- Cutting and fitting. Boards are cut to length and fitted one by one, with joints pushed tightly together and fixings hidden or easy to fill.
- Sealing and preparation. Gaps are filled, joints sanded smooth and boards primed. Sealing every face and edge matters in a damp room.
- Painting. The panelling is painted in your chosen colour with enough coats for a durable, wipeable finish, and sealant is applied around fittings where needed.
Colours and Finishes
Colour makes a big difference in a small room, and tongue and groove takes paint beautifully.
| Colour Direction | Effect | Works Well In |
| Soft whites and warm neutrals | Light, fresh, spacious | Small bathrooms with little daylight |
| Muted greens and blues | Calm, natural, spa-like | Bathrooms |
| Deep, dark colours | Rich, dramatic, cosy | Cloakrooms and downstairs toilets |
| Soft greys and taupes | Contemporary, understated | Modern bathrooms |
| Two-tone schemes | Defined and classic | Rooms with a dado or picture rail |
| Natural wood stain | Warm, rustic | Country and cottage styles |
A few practical tips:
- Choose a paint designed for bathrooms or high-moisture rooms
- A satin or eggshell finish wipes clean more easily than matt
- Test samples on the wall in both daylight and artificial light
Bathroom and Cloakroom Ideas
Bathrooms
- Full height panelling with a tiled shower area: warm timber with a waterproof tiled zone
- A painted feature wall behind the basin: frames mirrors and lighting
- A built-in shelf or ledge: a practical place for toiletries that adds interest
Cloakrooms
- A deep, dark colour: makes a small room feel intentional and memorable
- Beaded boards: add a traditional, country feel
- A built-in coat shelf or hooks: combines storage and decoration, and pairs well with a fitted boot room elsewhere in the home
- Matching woodwork: painting skirting, panelling and a bespoke internal door the same colour gives a polished look

Tongue and Groove Panelling FAQs
Can tongue and groove panelling be used in a bathroom?
Yes, provided it is properly sealed, painted and ventilated. It works well on walls away from direct water, and many people tile the shower area and clad the rest of the room.
Will tongue and groove panelling warp in a damp room?
It can if poorly prepared. Moisture-resistant boards, sealing every face and edge, thorough painting and good ventilation all reduce the risk significantly.
Is full height cladding better than half height?
In a small bathroom or cloakroom, full height often looks more cohesive and gives maximum protection. Half height can suit larger rooms where you want a painted wall above.
Can panelling be fitted around a basin and toilet?
Yes. We cut boards precisely around basins, toilets, cisterns, pipes and radiators, and seal the edges for a tidy finish.
Should I choose solid timber or MDF?
For a painted finish, moisture-resistant MDF is a popular, smooth and cost-effective option. For a natural stained look, solid timber is the better choice.
Can tongue and groove be fitted on uneven walls?
Yes. We scribe the edges and, where needed, fit battens to create a flat surface, so the finished result looks straight even if the wall is not.
How do I clean tongue and groove panelling?
Wipe it with a damp cloth and mild cleaner. A satin or eggshell paint finish is the easiest to keep clean.
Can I change the colour later?
Yes. Painted panelling can be repainted whenever you like, which makes it a flexible, long-lasting choice.
How long does installation take?
It depends on the size of the room and the number of fittings. It usually involves a measuring visit, a fitting stage and a finishing stage, with the timeline agreed in your quote.
