Classic baseboards are the opposite of modern. The profile is developed, the height is substantial, and the finish is usually a painted white that lets the profile read clearly.
The most common classic profile is the two-step baseboard. A plinth at the bottom (the part that touches the floor), a small step up to a flat or curved middle section, and another step up to a small cap or fillet at the top. The profile is 100 to 150 millimeters tall, with a clear geometry that catches light and shadow.
The three-step classic baseboard is more developed. A plinth, a larger middle section with a torus or ovolo profile, a small fillet, and a cap. The profile is 150 to 200 millimeters tall, sometimes with a separate cap and shoe molding.
The molded classic baseboard is the most developed. A plinth, a torus, a cyma recta, a small decorative band (a bead, a small dentil), and a cap. The profile is 200 to 300 millimeters tall, often with plinth blocks at the doors. Used in formal living rooms, dining rooms, and any room meant to read as period.
A classic baseboard always pairs with a chair rail and a cornice. The three pieces share a proportional language, and the room reads as properly designed when the proportions are right. Most factories sell classic baseboards as part of a coordinated trim family that includes the matching chair rail and cornice.
A practical note on plinth blocks. A plinth block is a small square or rectangular block at the base of the door casing, on both sides of the door. The baseboard butts into the plinth block instead of mitering at the door, which makes the install faster and the joint tighter. The plinth block is the same material as the baseboard, with the same finish.
For sourcing, classic baseboards are a standard product at most factories, with a wide range of profile options and heights. The price is higher per meter than a modern baseboard (more material, more detailed mold), but the visual difference is significant and the labor cost is the same.

Frequently Asked Questions
Q: What is a PU skirting board?
A: A PU skirting board (also called a baseboard) is a polyurethane molding installed at the floor-to-wall transition. It protects walls from scuffs and vacuum damage while delivering a clean architectural edge. PU skirting is waterproof, impact-resistant, and far lighter than the equivalent timber profile.
Q: How do you install Classic baseboards?
A: Cut Classic baseboards with a fine-tooth miter saw. Apply construction adhesive in a continuous bead along the back, press to the wall, and tack with finish nails into studs where possible. Mitre joints at inside and outside corners, fill with spackle, sand, and apply two coats of paint. PU skirting requires no sanding of the face — it arrives primed.
Q: Can PU skirting be used in wet areas?
A: Yes. PU skirting is fully waterproof and ideal for bathrooms, kitchens, and basements. Use a polyurethane adhesive (not water-based) and seal the bottom edge to the floor with a thin bead of clear silicone in wet zones to prevent mop water from wicking under the profile.
Q: What height skirting board should I choose?
A: Standard residential skirting heights are 60–100 mm (2.4–4 inches). For modern interiors, taller profiles (120–150 mm / 5–6 inches) deliver a more contemporary look and visually raise the perceived ceiling height. Heritage and Victorian restorations typically use 150–200 mm (6–8 inches) with a stepped or ogee profile.
