The room-specific choice of base trim is a small detail that has an outsized effect on how finished the room looks. Different rooms in the same house can have different base trims, and the right choice depends on the room's function and the design intent.
Living rooms, dining rooms, and entryways usually get the most substantial base trim. A 100 to 150 millimeter baseboard in a stepped or molded profile, painted the same white as the other trim in the room. The base trim is part of the room's architecture, and the more formal the room, the more substantial the base.
Bedrooms usually get a moderate base trim. A 80 to 120 millimeter baseboard in a simple stepped or cove profile. The bedroom is about rest, and the base trim is supporting, not dominant.
Bathrooms and kitchens get a waterproof base trim. A 80 to 120 millimeter PU baseboard in a stepped or cove profile, painted with a moisture-resistant enamel. The base trim has to perform in a humid environment, and PU is the right material.
Hallways get a continuous base trim that runs the length of the passage. A moderate profile, same as the rooms on either side, with attention to the joints at the corners. The hallway is the architecture that connects the rooms, and the base trim is the line that ties them together.
Stairways get a base trim that follows the angle of the stair. This is one of the more challenging base trim applications; the trim has to be cut at the angle of the stair rise, and the joints have to be tight on both the angled and the vertical sections. Most factories don't make a special stair baseboard; the same baseboard profile used elsewhere in the house is cut and installed at the stair angle.
Closets and utility rooms get the simplest base trim, or none at all. A small stepped or flat baseboard in a utility room is functional; a closet often has no base trim at all, or a small vinyl cove base that handles the cleaning and impact better than a decorative profile.
For sourcing, the same baseboard profile can be used throughout a house, with the height and detail level adjusted by room. The factory sells most profiles in a range of heights, and the right approach is to pick one profile and vary the height by room — taller in formal rooms, shorter in utility rooms.

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 Floor molding styles?
A: Cut Floor molding styles 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.
