A 1 panel shaker door is a single-panel interior door with a clean, rectangular Shaker-style design, typically sold primed and ready to paint.
If you’re shopping for a 1 panel shaker door, you’ve likely noticed listings vary wildly in price and description. That’s because this simple-looking door comes in several distinct configurations. The differences matter — a slab won’t work where you need a prehung unit, and a hollow-core door feels nothing like a solid-core one. Here’s what you need to know before you order.
Slab vs. Prehung: Which One Do You Need?
The most important choice is between a slab and a prehung unit. A slab is just the door itself — no frame, no hinges, no hardware. A prehung door arrives assembled with the jamb and hinges already attached, ready to drop into a rough opening.
Contractors Warehouse lists its “Interior 1-Panel Shaker Primed & Prehung Door” (SKU 583195) as a 24 in. x 80 in. left-hand unit, showing the level of detail you’ll need to specify.
Prehung units typically include standard hinges and come with the door pre-bored for hardware — but always confirm the bore prep before ordering, since some slabs arrive completely undrilled.
What Sizes Do 1 Panel Shaker Doors Come In?
Interior 1 panel shaker doors most commonly come in 6’8″ (80 in.) heights with widths of 18 in., 24 in., 28 in., 30 in., 32 in., and 36 in. Some lines also offer 20 in., 22 in., 26 in., and 34 in. widths, plus taller versions at 84 in., 90 in., and even 96 in. for oversized openings.
Most interior slabs are 1-3/8 in. thick, though some fire-rated or heavier options run 1-3/4 in. Prehung versions commonly use a 4-9/16 in. jamb to match standard 2×4 wall construction.
Measure twice before you order — returns on doors are expensive.
Solid Core vs. Hollow Core vs. Fire-Rated
The core type dramatically affects both price and performance. Hollow-core doors are lightweight, inexpensive, and fine for closets or low-traffic rooms. Solid-core doors weigh more, block sound better, and feel sturdier when they close.
SoCalTrim sells the “1 Panel Shaker Door (Solid Core)” and a separate “1 Panel Shaker Door (Fire Door)” as distinct product families.
| Door Type | Typical Price Range | Best For |
|---|---|---|
| Hollow core, no prep | $111 – $149 | Closets, utility rooms |
| Solid core, pre-drilled | $115 – $217 | Bedrooms, offices |
| Prehung unit | $179 – $217+ | New construction, full replacements |
| Fire-rated | $350 – $948 | Garage connections, code requirements |
What to Check Before You Order
Three details cause most ordering mistakes. First, confirm whether the door comes pre-bored for hardware. Some slabs arrive completely blank; others come pre-drilled for a standard lockset. Second, verify the handedness on prehung units (left-hand vs. right-hand) before you order. Third, double-check the core type, since solid and hollow versions of the same style can differ in price by $100 or more.
