Internal Doors

When it comes to selecting the perfect internal door for your home or office, there are various options to consider. Our range includes flush doors, panel doors, glazed doors, fire doors, laminated doors, pocket doors, and room dividers, each catering to specific needs and aesthetics.

Flush Doors

Flush doors, such as the Flush White Primed Interior Door, provide a sleek and modern appearance with a flat surface. These doors are versatile and can be used in contemporary or traditional settings. They are available in various finishes, such as white primed, oak, and more.

Panel Doors

Panel doors, like the Oak Melbourne Pre-Finished Internal Door and Knotty Pine 6 Panel Interior Door, offer a classic and timeless design with raised or recessed panels. These doors can be found in a variety of styles, including traditional 4 or 6 panel designs, as well as contemporary patterns.

Panel doors and traditional interior styles

Panel doors add detail through raised or recessed sections and can complement both traditional and contemporary rooms. Four-panel and six-panel designs are popular options, while shaker styles have a simpler framed appearance. Solid oak and oak-effect finishes can suit cottage-inspired interiors, while white painted or primed doors create a lighter look. Compare the panel layout, finish and available sizes, and check whether the door is ready to hang or needs painting or staining.

Glazed Doors

Glazed doors, such as the Utah White Primed 3 Glazed Clear Light Panels Interior Door and Soho Black Primed 4 Glazed Clear Light Panels Interior Door, feature glass panels that allow light to flow between rooms, creating a brighter and more open space. These doors are available in various styles, including clear or beveled glass, and can be used to add an elegant touch to any interior.

Glazed doors for brighter interiors

Glazed doors allow light to pass between adjoining rooms while maintaining a division between spaces. Clear glass creates a more open connection, while frosted or obscure glass can provide additional privacy. Compare the amount and arrangement of glazing, the door colour and the style of the frame. White primed and black primed options create different effects. Check the glass type, dimensions and finish on the product page before buying. Glazed doors can work well between halls, kitchens and living areas.

Fire Doors

Fire doors, like the Contemporary Moulded White Primed 4 Panel Interior Fire Door FD30 and Oak London 4 Panel Un-Finished Internal Fire Door FD30, are designed to provide additional protection in the event of a fire. These doors are made with fire-resistant materials and meet specific safety standards to help prevent the spread of flames and smoke.

Internal fire doors and FD30 options

An internal fire door is designed to help slow the spread of fire and smoke when installed as part of a suitable fire-resisting assembly. FD30 refers to a 30-minute fire-resistance rating under relevant test conditions. Check the product certification and installation instructions before choosing a door. The frame, hinges, intumescent seals, latch and other components must be suitable for the specification. Do not assume a standard panel door can replace a certified fire door. Ask a qualified professional or building control body if requirements are unclear.

Laminated Doors

Laminated doors, such as the Santandor Ivory Laminated Interior Door, feature a layer of laminate that adds durability and resistance to scratches and stains. These doors are ideal for high-traffic areas and come in a range of finishes and styles to suit any interior.

Laminated doors for everyday use

Laminated doors have a decorative surface layer and are available in finishes to suit different interiors. Compare the colour, texture and appearance with nearby furniture and flooring. A wipe-clean surface can be convenient in frequently used areas, but care requirements vary by product. Follow the manufacturer's cleaning instructions and check the stated construction, dimensions and finish before ordering. Confirm whether the door is supplied pre-finished and whether any additional preparation is required before installation.

Pocket Doors

Pocket doors, including the Flusso Pocket Door Double Set Interior Door and Flusso Pocket Door Single Set Interior Door, are space-saving options that slide into a compartment in the wall, making them an excellent choice for small rooms or tight spaces.

Pocket doors and single or double openings

Pocket doors slide into a cavity in the wall instead of swinging into the room, helping save floor space. A single door may suit a standard opening, while double pocket doors can create a wider passage. Check that the wall can accommodate the pocket frame and that pipes, cables or structural elements will not obstruct installation. Compare the opening width, door dimensions and supplied hardware. Confirm whether the track, frame and handle set are included or need to be ordered separately.

Room Dividers

Room dividers, like the Reims White Primed 20 Glazed Clear Bevelled Light Panels Interior Room Divider and Manhattan White Primed 36 Glazed Clear Bevelled Light Panels Interior Room Divider, are perfect for creating separate spaces within a large room. These doors feature multiple panels and can be used to add flexibility and functionality to any space.

Room dividers and glazed interior screens

Room dividers can separate a larger space while retaining a sense of openness. Multi-panel glazed designs can work between living and dining areas or help define a home office without blocking all available light. Consider the opening dimensions, number of glazed panels and whether clear or bevelled glass suits the room. Check the finish, frame requirements and supplied components. Choose a room divider according to the opening and intended layout, not appearance alone.

When choosing an internal door, consider the style and design of your space, as well as the practical requirements, such as fire safety and privacy. Our range of internal doors offers something for every need and aesthetic, ensuring that you can find the perfect door for your home or office.

How to compare internal door materials and finishes

The material and finish influence the appearance, preparation and care of an internal door. Solid oak provides a natural timber look, while oak veneer offers an oak surface over a different construction. White primed doors are prepared for painting, while unfinished doors need suitable sealing, staining or painting as instructed. Pre-finished doors have a factory-applied finish and can be convenient when you want a ready-made appearance. Check the product details and treatment requirements, including any exposed edges after trimming.

Measuring the correct internal door size

Accurate measurements help you choose an internal door that suits the existing frame. Measure the width at the top, middle and bottom, and the height on both sides. Compare the smallest relevant measurements with the product dimensions, and confirm whether the listing gives the door-leaf size. Common UK imperial widths include 610mm, 686mm, 762mm and 838mm; metric options are also available. Check the exact dimensions and trimming limits before ordering, rather than relying only on an old door's size.

• Panelled and shaker doors for traditional homes
• Flush and vertical-panel doors for a modern look
• Glazed doors (clear or frosted) to bring light into halls

Door sizes for narrow and awkward openings

Some properties have non-standard openings, particularly older homes, cottages or rooms that have been altered. A narrow door may suit a cupboard or compact space, while a wider opening may need a larger door or a double-door arrangement. Compare the listed height, width and thickness with your frame. Check the permitted trimming amount, as it varies by product. Fire doors have stricter limits and must not be cut beyond the manufacturer's allowance. Confirm measurements before making adjustments.

Materials and finishes

• Solid oak and oak veneer
• White primed doors to paint on site
• Pre-finished vs unfinished: what each needs before hanging

Painted, primed and pre-finished door options

The finish affects how much preparation is needed before installation. A white primed door has a prepared surface intended for painting, allowing you to choose a colour that matches the room. An unfinished door needs sealing, staining or painting in line with the manufacturer's instructions. A pre-finished door has already been painted, lacquered or treated at the factory. Check whether cut edges need additional treatment and follow the product guidance to protect the finish and warranty.

Planning the installation and checking the frame

Before fitting a new internal door, check that the frame is sound, square and suitable for the selected door. Compare the door thickness and dimensions with the frame, hinges and latch position. Read the manufacturer's instructions for hinge positions, clearances and trimming allowance. The door should open and close without catching on the floor or frame. Pocket doors and pairs need compatible systems and accurate opening measurements. Fire doors require specified components and installation methods.

• Common imperial sizes: 1981mm high x 610, 686, 762 or 838mm wide
• Metric sizes such as 2040 x 726mm and 826mm (726mm doors)
• Narrow internal doors and wide doors for awkward openings

Fire door hardware, seals and safety details

A fire door is only one part of a complete fire-resisting installation. Depending on its specification, the correct frame, hinges, latch, closer and intumescent or smoke seals may also be required. These components must be compatible with the certified door set and installed as instructed. Do not replace specified hardware with general door furniture unless the documentation confirms it is suitable. Check certification and trimming limits before work begins, and seek professional advice if building requirements are unclear.

Choosing handles, hinges and other door accessories

Door furniture completes the appearance and everyday function of an internal door. Handles are available in different shapes and finishes, so consider how they coordinate with other fittings. Check whether hinges, a latch or a handle pack are included, as these may need to be purchased separately. Confirm hinge type, latch position and door thickness before choosing accessories. Pocket doors may need recessed pulls or specialist hardware. For fire doors, all fittings must meet the product's certification requirements.

• Handles and door handle packs
• Hinges and frames

Consider the privacy needed in each room when choosing a door style and hardware. Bedrooms and bathrooms generally call for a more enclosed design, while glazed options may be suitable where sharing light is a priority. Check that the latch and handle are appropriate for the room and compatible with the door construction. For any specialist security requirement, review the product specification rather than assuming all internal doors provide the same level of protection.

Privacy and security when selecting a door

Before adding a door to your order, review the product page for its exact size, finish, handing, construction and included accessories. Check availability and delivery information, especially if you are buying several doors for one project. If you need matching frames, hinges or handles, confirm compatibility with the selected product. Keeping these details together can help avoid delays and make it easier to complete the installation as planned.

FAQ

Finding the right internal door for your home

When comparing products in an online shop, use filters to narrow the range by style, finish, size and door type. Read each product description to confirm whether it is a panel, glazed, flush, pocket or fire door. Check dimensions, construction, finish and included components, as similar-looking products can have different specifications. Product photographs help compare styles, but technical details should guide the final choice. Contact the supplier if you need help checking measurements or compatible accessories.

What size are standard internal doors in the UK?

The most common imperial sizes are 1981mm high by 686mm, 762mm or 838mm wide. Metric doors are usually 2040mm high, with widths such as 726mm and 826mm. Always measure your door frame before ordering.

How do I choose between a single door and double doors?

A single door usually suits a standard doorway, while double doors can work for a wider opening or a more open connection between rooms. Measure the full opening and check the space available for both leaves to swing. Confirm that the frame, hinges and closing hardware suit the arrangement. Some products are supplied as a pair, while others may need to be ordered separately. If space is limited, consider a pocket door or another suitable style.

What is the difference between pre-finished and unfinished doors?

Pre-finished doors are lacquered or painted in the factory and are ready to hang. Unfinished doors need sealing, staining or painting on all faces and edges, and the manufacturer's warranty usually depends on this being done.

How should I care for internal doors?

Regular, gentle care can help keep internal doors looking presentable. Dust surfaces and clean marks with a soft cloth using a method suitable for the finish. Avoid abrasive cleaners or excess water, particularly on timber, veneer and unfinished surfaces. Painted, lacquered and laminated doors may have different care requirements, so follow the manufacturer's guidance. Check hinges and handles occasionally and treat any trimmed or exposed edges as instructed. Suitable care helps protect the finish over time.

Can internal doors be trimmed to fit?

Most doors can be trimmed by a small amount on each edge. The allowance varies by door, so check the product details before cutting. Fire doors have stricter limits.

Do I need a fire door inside my home?

Building Regulations can require fire doors in some places, for example between a house and an integral garage, or on rooms off the stairs in homes with three or more storeys. Check with your building control body.
