Internal Doors

Door Superstore offers hundreds of options on internal doors in the three most common internal door widths, as well as a variety of other sizes. 686mm, 762mm and 838mm widths are the most sought-after widths for interior doors but we like to give our customers complete choice so we offer widths from 381mm all the way up to 926mm. Opting for an unusual size of door doesn’t mean you have to compromise on style either! 

Internal door finishes

Door Superstore gives you full creative control over your home with internal doors in many finishes. Whether you’re after a finished and ready-to-go hardwood internal door or you’re looking for a primed and pre-finished door (so you can paint this yourself) you’ll find something suitable. Oak, pine and hardwood make up a stunning ‘wood’ range of doors which run alongside options such as veneered, moulded and hollow core doors. 

Other considerations for internal door finishes include the colour too. Perhaps grey internal doors or a mocha shade would suit your theme better? Or would you rather keep it neutral with walnut or white painted finishes?

Can you trim internal doors? 

Most internal doors manufacturers advise different trimming tolerances so as a standard and to be on the safe side we advise that you don't trim more than 5mm per side. This is with the exception of LPD, which only allow 3mm on each side. It's worth noting that if you're needing to trim a lot off of a door then you probably have the wrong size and may be able to buy exactly what you need. If you do need to trim to 6 or 7mm, contact us with your chosen brand and we'll help you find out if this is okay. Trimming over a manufacturer's tolerance will void any warranties.

The construction of door will impact how much you can trim too as, with hollow core doors, for example, you will eventually cut into the void and render the door unusable. Similarly, there are design elements to think about. Trimming the amount you need to trim might mean that a design feature is taken away. In the image to the right, if you trimmed too much you'd impact the look of the doors.

Internal door styles 

Big brands like Premdor, XL Joinery and JB Kind come together in one place here to present every style of door for any modern or traditional home. Sleek and sophisticated glazed doors offer a touch of modernity while classic options like internal panel doors and flush doors bring a traditional air. White internal doors can help to brighten a room and add a touch of detail where required.

1930s doors are another popular design of internal door, designed with a classic 3-panel bottom, and a single panelled top half. Alternatively, cottage internal doors are doors that have been manufactured to create the appearance of a traditional cottage door in historic rural Britain, but with the benefits of a contemporary internal door. 

To complete your project yourself why not opt for a primed and unglazed internal door? You can select the style of your door without needing to commit to any type of glazing and without committing to a colour too. Opt for privacy glazing with a light grey paint for the bedroom but use the same door with transparent glazing for the study. 

Bi-fold internal doors are ever-popular with homeowners and developers alike since they offer an expensive-looking yet practical finish. Bi-fold doors between kitchens and dining rooms, for example, give homeowners the choice of closing the door for a more intimate family dinner, or you could open the door fully for a more social occasion like Christmas, without needing as much floor space free like a regular door. Alternatively, opt for room dividers to create a temporary wall or split within the room. 

Which type of internal door is best for you? 

Doors are made from a range of different materials, with different structures, and each has its own benefits.From pine cottage doors to interior panel doors, there is a wide variety of internal timber doors to discover. 

Solid wooden internal doors

Solid wooden doors have been popular for years, and are made from a single piece of timber. This gives them strength and weight, making them feel high quality, and solid wooden internal doors can be both contemporary or modern in design, and their solid construction means that they can be trimmed to fit your doorway. Choose from wooden interior doors made from wood such as pine, oak and walnut to give your home a classic and high-quality finish. You can also discover large internal doors and many more different style interior wooden doors to suit the theme of your property.

Engineered core internal doors

Internal doors with engineered cores, also known as solid-core doors, are doors that have a solid core, with a fine grade surface veneer attached to each side of the core. They are sturdy and quite heavy and give the appearance of a solid wooden door without the high price tag.

Moulded internal doors

Moulded internal doors are manufactured using wooden bi-products that are pressed together to form a door. Often less expensive than solid wooden doors, moulded doors come in a range of sizes and shapes which gives you more options to help you find the perfect internal door.

Flush internal doors

Flush doors typically have a completely smooth surface to them, giving a minimalist feel to your home. They tend to consist of an engineered core with a hollow frame, covered with plywood or MDF to form the door. They are much more lightweight, and cannot be trimmed to size, but they are a budget friendly alternative for an internal door. Internal flush doors come in a range of styles, with features such as panels, grooves and stains to add a great finishing touch for both traditional and contemporary homes.

Panelled internal doors

Panelled internal doors have been constructed with a number of different panels instead of a single piece of wood. Popular in homes and buildings throughout the UK, panel doors have a structure that provides stability and durability, as well as variety - you can choose from 2, 4 or 6 panelled internal doors for your home.

Space-saving internal doors

Save space with pocket doors and folding doors. These space-saving internal doors free up a surprising amount of space in a home as they reduce the amount of floor space ‘clearance’ that’s needed in front of or around every interior door. Pocket doors, also known as sliding doors, operate on a rolling track to slide into the wall cavity instead of swinging outwards. Pocket doors reduce floor space needed and give versatility, especially if the pocket door is used to separate a dining room and living room for example as they can be opened for social occasions. 

Folding doors, known as bi-fold doors, can be used internally all throughout the home in living room doors, bedroom doors and for things like wardrobe doors too. When folding doors are open they take up only half the floor space of a regular door so they’re a great space-saving product.

Internal fire doors

By strategically placing internal fire doors throughout your home you can combat the spread of fire should one ever break out, giving your family a much better chance of escaping your home unscathed. Fire doors typically offer around 30 minutes of fire protection, and they are conducive to preventing too much smoke from moving between rooms. Fire rated handles and hinges ensure the door stays in place and accessible during a fire too. 

Other things to consider when purchasing new internal doors

If you’re selecting new internal doors for your home then it’s important to identify whether you’re also replacing the door linings and other components too. If you’re getting a new door frame then select any size hinges and they’ll match up, but if you’re sticking with your existing door frame and getting new hinges then consider picking the same sized hinges as before so everything lines up. This means no new hinge positions are needed, which could make the old holes visible when the door is in a certain position.

Handles and latches are not commonly supplied with interior doors so if you’re old handles won’t match your new door then it’s wise to get new ones. It’s also important to consider if the handles and doors are totally different styles too. For example, if your existing handle is a simple flat lever but the door you’ve chosen is bi-fold or the handle positioning is very high, this won’t work. 

Latches are key to ensuring your door closes properly and securely, even if there is a breeze or it’s slammed. The latch on your door needs to smoothly and securely sit into the strike plate (the metal section on the door frame that typically contains the lock mechanism) to keep the door in place. It’s worth identifying if your latch and strike plate sit nicely or if it’s worth spending a few pounds to get a new pair. Don’t forget, if the latch on your new door will be in a different place to the existing latch, you’ll need to move the strike plate so it all lines up.
