Solid Oak Shelves – Made to Measure
Our solid oak shelves are handcrafted from premium kiln-dried European oak and cut to your exact size. Designed for both floating shelves and bracket shelving, they provide a timeless and durable storage solution for kitchens, living rooms, alcoves, bathrooms and commercial interiors.
Each shelf is carefully prepared in our Pembrokeshire workshop by our skilled joinery team, ensuring a beautifully finished piece of natural timber that highlights the warmth, grain and character of real oak.
Celtic Timber has been supplying oak shelving, oak beams and bespoke timber products for over 20 years, trusted by thousands of households, interior designers and tradespeople across the UK.
Premium Joinery Grade Oak
Our shelves are produced using Premium joinery grade European oak, selected for its cleaner appearance and structural stability. Compared with character grade timber, joinery grade oak contains fewer knots, cracks and blemishes, creating a refined finish suitable for modern and traditional interiors.
The oak is kiln dried to reduce moisture content and minimise movement after installation, helping ensure your shelves remain stable and long-lasting once fitted.
Made to Order
Every shelf is handcrafted to order, allowing you to choose from a wide range of sizes, edge profiles, support options and oil finishes to suit your space.
Each piece is:
• Carefully planed to ensure straight, square edges
• Smoothly sanded for a refined furniture-grade finish
• Prepared ready for installation and finishing
Shelves are supplied unfinished with your chosen oil colour included, allowing the final finish to be applied after installation for the best results.

Our solid oak shelves are available with two edge styles so you can choose the look that best suits your space.
Square Edge
A clean, straight edge with a modern and refined appearance.
This option works well in contemporary kitchens, modern interiors and minimalist spaces where a crisp, uniform finish is preferred.
Live Edge
A natural “waney” edge that follows the original shape of the tree.
This keeps the organic character of the oak and creates a more rustic, unique look, ideal for farmhouse kitchens, cottages and character homes.
Because live edge shelves follow the natural grain of the timber, each shelf will have its own individual shape and character.
Both edge styles are carefully sanded and prepared so they are smooth to the touch and ready for finishing or installation.

Installation Guidance
Solid oak is a natural, structural timber and should be installed correctly to ensure long-term stability and performance.
Acclimatisation
Before installation, we recommend allowing your oak shelf to acclimatise in the room where it will be fitted for several days. This allows the timber to adjust to the ambient temperature and humidity levels.
- Store flat
- Keep away from direct heat sources
- Do not lean upright against a wall
Supporting the Weight
Oak shelves are solid and heavy. Proper support is essential.
- Use appropriate type and number of brackets or battens where required. This depends on thickness and length of your shelf.
- Avoid leaving large unsupported spans.
For installations above radiators, allow airflow to prevent excessive heat build-up beneath the timber.
Fixing Advice
- Secure using suitable fixings into masonry or framing
- Avoid over-tightening screws
- Always allow for natural expansion and contraction
We recommend fixing the shelf close to the delivery date to minimise movement prior to installation.

Timber Variation & Natural Characteristics
Oak is a natural material, and every board is unique. No two oak shelves will ever look identical — and that’s part of the beauty.
Colour variation
Solid oak can vary in tone from light golden hues to deeper honey shades. Over time, exposure to light will naturally mellow and deepen the colour. This is not a defect — it is a natural characteristic of genuine solid oak.
Grain and knots
You may see natural knots, grain variation, small checks or character markings, and subtle colour shifts. These features add authenticity and character to your window sill.
Joined boards (for wider widths)
For widths generally over 150mm+, boards may be professionally joined to achieve the required depth. We carefully match grain and tone to ensure a seamless, natural appearance. All joints are structurally secure and finished to the same high standard.
Natural movement
As a natural timber product, oak may expand or contract slightly depending on environmental conditions. Correct installation and acclimatisation will minimise movement.

Are your shelves solid oak?
Yes. All of our Oak Shelves are manufactured from solid kiln-dried European oak here in our Pembroekshire Workshop - We do not use veneer or MDF-wrapped products.
Can you make them to my exact size?
Yes. Every window shelf is cut precisely to the millimetre to match your measurements.

This depends on the look you want and the size of the opening. Thicker boards provide a more substantial, architectural feel and are ideal for larger rooms or the wow factor.

Yes, provided adequate airflow is maintained and the shelf is properly supported. Oak is durable, but excessive heat build-up should be avoided.

Shelves are supplied planed and sanded to a fine finish, ready for oiling, staining or sealing to suit your interior.
How long is the lead time?
Current lead time is approximately 2–3 weeks from order completion.
