Grooved Door Profiles Explained: Square, U & V Groove

What’s the Difference Between U Groove, V Groove & Square Groove Doors?

When choosing interior doors, the design options can seem endless. One popular feature you might consider is grooved doors, which come in a range of styles to suit your home’s look. Whether you’re matching an existing door or adding character to a new build, grooved doors offer both functionality and aesthetics.

Types of Groove Profiles

The groove profile refers to the shape of the grooves or cuts when viewed up close. The main types include:

U Groove Door Profile

U Groove

Characterised by its rounded, smooth edges, the U Groove creates a soft, subtle line in the door. This profile is popular because it often looks better once painted, as the paint flows smoothly into the groove without any harsh edges.

V Groove Door Profile

V Groove

The V Groove has sharp, distinct lines, forming a V shape in the door's surface. This profile gives a more defined look and can add depth to your door design. However, it requires a thicker door skin, usually 4mm or more, making it slightly more expensive than other options.

Square Groove Door Profile

Square Groove

The Square Groove features a straight, squared-off edge. While this design offers a clean, modern look, achieving a perfect paint finish can sometimes be tricky. The edges may require more attention during painting to ensure a smooth result.

Material Choices for Grooved Doors

Grooved designs can be applied to different door cores:

  • Hollow Core: Lightweight and affordable, but less sturdy.
  • EPS Solid Core: Offers more solidity while still being cost-effective.
  • MRPB Solid Core: The most durable option, ideal for high-traffic areas.

Cost Considerations

When it comes to cost, U Groove and Square Groove doors are typically priced the same. However, the V Groove door is more expensive due to the need for a thicker skin. The deeper cut of the V Groove means it can’t be applied to the standard 3mm skin, requiring an upgrade to a thicker material.

Choosing the right groove profile for your doors depends on your aesthetic preference, the desired durability, and your budget. U Groove and V Groove doors often provide better paint results, while Square Groove offers a modern, clean look that may need extra care during finishing.

Whether you’re renovating or building new, understanding these groove profiles can help you make the best choice for your home.
