Inside door styles for UK homes

Internal doors come in several style families that suit different property types and interior schemes.

Panel doors

Panel doors are the traditional UK internal door style. A 4 panel door has two pairs of stacked panels. A 4 panel internal doors configuration suits Victorian, Edwardian and most 20th century properties. 6 panel doors and 6 panel interior doors give a more decorative profile, common in 1930s and 1950s homes. 2 panel doors are the simpler option suiting Georgian and contemporary properties. 3 panel door and 5 panel door configurations sit between the standard options for specific period properties.

Shaker internal doors

Shaker internal doors have flat panels framed by simple rails and stiles. The understated profile suits modern, contemporary and period properties equally well. Shaker has been the dominant new build internal door style for over a decade.

Glazed internal doors

Glazed internal doors let light flow between rooms. A glass panel door is commonly specified between kitchen and hallway, between living room and dining room, or in any room that would otherwise feel dark. Clear glass works where you want maximum light. Frosted or textured glass gives privacy. Internal doors with glass are the second most-requested internal door category after solid panelled.

Cottage internal doors

Cottage internal doors typically have a ledged-and-braced construction with horizontal boards. The look suits cottages, period rural properties and rooms going for a traditional rustic aesthetic. Often paired with cast iron furniture rather than brass.

Flush internal doors

Flush internal doors have a smooth face with no visible panel detail. Modern flush doors suit contemporary properties, hotels and apartments. The finish is usually a wood veneer, painted MDF or laminate.

Internal door materials and construction

Engineered timber

The standard internal door construction. An engineered timber frame with veneer or paint-finish surfaces, typically with a hollow or honeycomb core for light weight, or a solid core for better sound reduction. Most of our internal door range uses engineered timber construction because it stays flat over decades without warping.

Solid core interior doors

Solid core interior doors weigh more, reduce sound transfer between rooms more effectively, and feel heavier when opening and closing. Recommended for bedrooms and bathrooms where sound matters, and for upmarket interior schemes where the door action is part of the experience.

Solid wood doors

Solid wood doors and interior wood doors are the premium internal door option. Made from solid timber rather than engineered cores, they offer the heaviest action and best sound reduction. The trade-off is higher cost and the need to allow for seasonal timber movement during installation.

Internal door configurations

Single internal doors

The standard configuration. One door hinged on one side, opening into the room. Most UK internal doorways use single doors.

Internal double doors

Internal double doors and interior double doors open up the full width of an opening. Common between living and dining rooms, between kitchens and snugs, or as feature doors into formal rooms. The double-door look adds presence to an interior.

Internal bifold doors

Internal bifold doors fold back to one side rather than hinging open. Used where floor space for a hinged door arc isn’t available, particularly in narrow hallways, wardrobes and en-suite bathrooms. Folding doors internal and folding doors interior configurations work well for room dividers between open-plan spaces.

Sliding doors internal

Sliding doors internal configurations slide along a track rather than hinging. Pocket doors slide into a wall cavity for a fully-recessed finish. Interior sliding doors and surface-mounted sliding doors slide along an exposed track. Used where space is tight or for design statements in contemporary properties.

Glazed internal door configurations

Glazed internal doors come in several configurations.

A single full-length glass panel for shaker doors gives maximum daylight transfer. Twin glass panels in upper sections of traditional panelled doors keep the lower half solid. Fully glazed designs for contemporary interiors maximise the visual connection between rooms.

Internal double doors with glass work particularly well between dining rooms and living rooms where you want to open up the full width without losing the daylight flow when the doors are closed.

For configurations involving the 4 panel sliding glass door layout, the sliding action combines with a glazed look for properties wanting both daylight and the contemporary sliding aesthetic.

Internal door colours and finishes

The most-requested internal door colours track the popular interior schemes.

Oak internal doors

Oak internal doors with natural veneer grain are the most popular UK internal door finish. The warm honey tone of natural oak works in both traditional and modern interiors, and the grain pattern hides everyday marks better than painted finishes. Oak veneer doors over engineered cores give the authentic look without the cost of solid oak. Solid wood doors and solid wood interior doors are the premium option for properties where the budget allows.

Internal wooden doors in oak, walnut, ash and other timber species suit traditional and period properties particularly well. The natural grain variations between internal wooden doors mean each door has a slightly different appearance, which adds character that uniform painted finishes can’t match.

White internal doors

White internal doors are the most popular finish for modern UK homes. White interior doors keep spaces feeling bright and pair with most flooring and wall colours. Common across new builds, renovated period properties and rental properties for the universal appeal.

Grey internal doors

Grey internal doors have grown rapidly in popularity for contemporary properties. Anthracite and slate grey suit shaker and flush configurations particularly well. Pairs naturally with grey or anthracite kitchens.

Black internal doors

Black internal doors and black interior doors make a statement in contemporary properties. Matt black works on shaker designs. Glossy black suits glazed internal doors for high-end modern interiors.
