Modern solid wood interior doors can bring natural grain, warmth, and a more substantial feel to a room, but the products in this roundup are built in different ways. Some are made from solid pine or alder, while others use wood veneers or MDF panels over a core. Compare the construction, dimensions, finish requirements, and hardware before choosing—especially if you are replacing a door in an existing frame.

Our Picks: Best Modern Solid Wood Interior Doors reviews
1. LUBANN Solid Alder Door: A Warm, Unfinished Option for Taller Openings
The LUBANN is a solid alder door panel with a natural grain pattern and an unfinished surface. Its 32-by-84-inch size makes it taller than the 80-inch doors elsewhere in this list, so it may suit a room with a taller opening or a renovation designed around a nonstandard door height.
Because it arrives unfinished, you can choose a stain, clear coat, or paint to suit your room. The product description says the panel is pre-assembled and includes a hardware kit; it also describes matte-black sliding hardware with a 38-inch track. Confirm the hardware configuration and compatibility with your opening and installation plans before ordering.
This is the most direct choice here if you want an actual solid-wood door with visible grain. Its main drawback is that the taller size and sliding-door setup may not work with a standard hinged-door opening. Measure the opening and check clearances rather than relying on the “standard 32-inch” wording alone.
Pros:
- Solid alder construction with natural wood grain
- Unfinished surface can be stained, painted, or clear-coated
- Pre-assembled panel
- Hardware kit is described as included
Cons:
- 84-inch height may not suit a typical 80-inch opening
- Confirm that the included sliding hardware fits your intended setup
Verdict: Choose the LUBANN if you want solid alder and a customizable finish, and your opening can accommodate its taller panel and hardware.
2. ETO DOORS Brentwood: A Clean White Oak Look with Horizontal Grooves
The Brentwood pairs a flush face with three horizontal grooves and a matching horizontal grain pattern. That restrained design gives it a contemporary look without raised panels or decorative molding.
This is a solid-core door, but it is not made entirely of solid wood: the description specifies vertical-grain white oak veneers over a PBC core. The core is described as providing structural strength, dimensional stability, and improved sound performance. The door is an unfinished slab, so finishing and installation work are part of the project.
At 30 by 80 inches and 1¾ inches thick, this model is narrower and thicker than several other options here. The description lists additional widths, but confirm the exact size and slab specifications on the product page. It can suit a modern bedroom, office, or other interior where you want an oak appearance and a substantial solid-core construction.
Pros:
- Modern flush face with three horizontal grooves
- White oak veneer offers a wood-grain appearance
- Solid-core construction is designed for stability and sound performance
- Unfinished surface allows a custom finish
Cons:
- Veneer over a PBC core is not all-solid-wood construction
- Sold as an unfinished slab, not a prehung door
Verdict: Pick the Brentwood if a contemporary oak look and solid core matter more to you than an all-solid-wood build.
3. JUJUBON Two-Panel Pine Slab: A Knotty, Stainable Door
This 36-by-80-inch slab is described as a knotty pine door with a two-panel design. Its visible knots and natural color give it a more rustic character than the smooth, flush ETO DOORS option. The unfinished, pre-sanded surface is intended to be stained or painted.
The listing says the slab is 1⅜ inches thick and comes without bore holes, hinges, a frame, or other hardware. That gives you more freedom to set up the door for your project, but it also means you will need to plan the hardware and installation yourself. The description says it can be trimmed up to half an inch on each side; check the product details and consult an installer before cutting, particularly if you need to preserve the panel’s proportions.
The supplied product information lists this item as unavailable. Availability can change, so check the listing before planning around it. If it becomes available, it may suit buyers looking for a natural pine look, but its unfinished slab format calls for more preparation than a ready-to-install door.
Pros:
- Knotty pine offers a distinct natural-wood appearance
- Unfinished, pre-sanded surface is ready for a custom finish
- Assembled slab can be used in several interior door setups
- Product description allows limited trimming
Cons:
- Hardware, frame, hinges, and bore holes are not included
- Listed as unavailable in the supplied product information
Verdict: Consider the JUJUBON if you want a knotty pine slab and are prepared to handle finishing and hardware, but verify that it is available first.
4. Door Elements Pine Louver Door: A Ventilated Choice for Closets
The Door Elements slab uses open louver slats to allow airflow, making it a practical style for a closet or another interior space where ventilation matters. Its 32-by-80-inch dimensions are closer to a common interior door size than the taller LUBANN panel, though you should still match the actual slab dimensions to your opening.
The product description identifies the rails and slats as solid pine, with multi-finger-joint pine used for the top and bottom rails. The open design is the main trade-off: it provides ventilation, but it does not offer the same visual privacy or sound separation as a closed-panel door. The door is described as ready for installation, but it must be sealed or finished to help preserve the wood.
This is a specialized pick rather than an all-purpose modern door. The louvered face gives it a more traditional utility look than a flush slab, but it can be a better fit when airflow is more important than a solid visual barrier.
Pros:
- Solid pine rails and louver slats
- Open slats allow airflow
- 32-by-80-inch size suits many standard door plans
- Can work in a range of interior applications
Cons:
- Open slats provide less privacy than a solid panel
- Must be sealed or finished to preserve the wood
Verdict: Choose this pine louver slab for a closet or other space where ventilation is useful and a closed, sound-blocking door is not the priority.
5. Lioncode Pine and MDF Slab: A Paint-Ready Panel Door
The Lioncode is a 32-by-80-inch slab with a solid pine frame and MDF panels. That mix is worth noting if you are specifically shopping for an all-solid-wood door: this one combines solid wood framing with engineered panels rather than using solid wood throughout.
It comes with a primer finish, not a final coat of paint. The product description advises lightly sanding before applying your chosen topcoat. The door has no pre-drilled holes, and the frame, hinges, lockset, and other hardware are not included, so you can customize placement but should plan for the extra work and parts.
The listing describes the door as moisture resistant and intended to help reduce noise transmission. The supplied product information lists it as unavailable, so check the listing before considering it for a project. If it becomes available, its primed surface may appeal to buyers who want a painted door rather than visible wood grain.
Pros:
- Solid pine frame with MDF panels
- Primer finish can be painted to match your room
- Standard 32-by-80-inch slab dimensions
- No pre-drilled holes, allowing custom hardware placement
Cons:
- Not an all-solid-wood door
- Hardware is not included, and the listing is marked unavailable in the supplied product information
Verdict: The Lioncode is worth considering if you want a paint-ready, mixed-material slab, but it is not the right pick if solid wood throughout is essential.
How to Choose a Modern Solid Wood Interior Door
Check what “solid wood” means for the door
Door descriptions can use terms such as solid wood, solid core, and wood veneer to describe different constructions. The LUBANN is described as solid alder, and the Door Elements model uses solid pine rails and slats. By contrast, the ETO DOORS model has white oak veneer over a PBC core, while the Lioncode combines a pine frame with MDF panels. If natural wood throughout is your priority, read the construction details rather than relying on the product title alone.
Measure the slab and opening carefully
Check the door’s width, height, and thickness against the existing opening and frame. The products here range from 30 to 36 inches wide and include both 80- and 84-inch heights. Also confirm whether the stated measurements describe the door slab or the opening it is intended to fit. A slab is not the same as a prehung door, and a mismatch can require extra carpentry or a different frame.
Decide between a slab and a prehung door
Most of the options in this roundup are described as slabs. A slab is the door panel alone; it usually does not include a frame, hinges, or a lockset unless the listing says otherwise. A prehung door comes mounted in a frame. If you are replacing only a door panel and can reuse your existing jamb, a slab may work. If you are replacing the whole doorway assembly, confirm what is included before ordering.
Choose a finish that matches your room and your skill level
Unfinished wood gives you control over the final color, but it needs preparation and a protective finish. Alder and pine can show their grain under stain or clear coat, while the primed Lioncode is aimed at a painted finish. The ETO DOORS white oak slab is also unfinished. Check the maker’s finishing instructions and make sure you have the time and supplies to complete the work.
Match the door style to the room’s needs
A flush door with simple grooves can suit a modern room, while knotty pine has a more rustic feel. Louvered doors allow airflow, but the open slats provide less privacy than a solid face. Think about how the room is used: a closet may benefit from ventilation, while a bedroom or office may call for a more closed design.
Confirm hardware, handing, and installation details
Check whether the slab has bore holes and whether hinges, handles, tracks, or other hardware are included. The JUJUBON and Lioncode descriptions specify that holes and key hardware are not included. The LUBANN description mentions a hardware kit and sliding track, so verify that setup against your opening before purchase. For any door, confirm the swing or sliding arrangement, clearances, and installation requirements with the seller or an installer.
FAQs
Are all of these doors made entirely from solid wood?
No. The LUBANN is described as solid alder, and the Door Elements model uses solid pine rails and slats. The ETO DOORS model uses white oak veneer over a PBC core, and the Lioncode combines a pine frame with MDF panels. The JUJUBON is described as knotty pine.
What is the difference between a solid-core door and a solid-wood door?
A solid-core door has a dense core, but its face may be veneer or another material rather than solid wood. The ETO DOORS Brentwood is a solid-core example with white oak veneers over a PBC core. Check the listed construction to see what materials make up the face and core.
Do these products include a door frame and hinges?
Most are described as door slabs, not complete prehung assemblies. The JUJUBON and Lioncode listings specifically say that frames and hinges are not included. The LUBANN description mentions a hardware kit, so confirm exactly what is in the package before ordering.
Which option is best for a closet that needs airflow?
The Door Elements pine louver slab is the clearest fit for that use because its open slats allow ventilation. Keep in mind that the slats also mean less privacy than a solid panel.
Can unfinished wood doors be painted or stained?
The LUBANN and JUJUBON are described as unfinished and suitable for custom finishing. The ETO DOORS slab is also unfinished. The Lioncode comes with primer and is intended for a topcoat. Follow the product’s finishing instructions and prepare the surface as directed.
What should I do if a listing is marked unavailable?
Availability can change, so check the product page before making plans around a specific door. The supplied information lists the JUJUBON and Lioncode as unavailable; consider another size or construction if either remains unavailable when you are ready to buy.
Final Recommendation
For a natural-grain door described as solid wood, the LUBANN alder panel is the strongest match in this group, provided its 84-inch height and sliding hardware suit your opening. For a crisp contemporary look, the ETO DOORS Brentwood offers horizontal grooves and a solid core, but its oak surface is veneer. Choose the Door Elements louver slab when airflow matters most, and treat the JUJUBON and Lioncode as options to revisit only if their listings become available. Measure first, verify construction and included hardware, and choose the door that fits both your room and your installation plan.
