Carpet is still the dominant floor covering in commercial offices. The question for most projects is not whether to use carpet but which format: modular carpet tile or rolled broadloom. The two products solve different problems, and the wrong choice can mean replacing a floor years before it would otherwise need attention.
This guide compares carpet tile and broadloom head to head across the seven criteria that actually drive the decision: appearance, replaceability, installation speed, cost per square foot, lifecycle cost, suitability for occupied spaces, and how each handles modern office layouts. We use both in San Francisco offices every week and have strong opinions about when each is the right call.
What Each Product Actually Is
A quick definition is worth setting before the comparison.
Carpet tile: Modular carpet squares, typically 24 by 24 inches or 18 by 36 inches, installed dry-back, glue-down, or self-stick. The tile format means individual sections can be lifted and replaced. Carpet tile dominates the commercial market for good reason.
Broadloom: Rolled carpet, typically 12 feet wide, installed as one continuous piece with seams hidden along walls or under furniture. Broadloom delivers a seamless look that tile cannot match. It is the carpet of choice when aesthetics drive the decision.
Both come in nearly identical fiber options (nylon 6, nylon 6,6, solution-dyed polyester) and similar backing options. The format is the difference, and the format drives every other tradeoff.
Appearance: Where Broadloom Still Wins
If the design intent is a seamless, hospitality-grade aesthetic, broadloom is the right answer. The visual difference is real.
Pattern continuity: Large patterns, gradient colors, and custom designs read better in broadloom because the pattern is not interrupted by seams every two feet. Lobbies, conference rooms, executive suites, and any space where the carpet itself is part of the design statement benefit from broadloom.
Seamless visual flow: A 12-foot-wide roll covers most rooms with one seam or none. That single visual surface reads more residential, more curated, more high-end. Carpet tile, no matter how well installed, always shows tile lines in the right light.
Pile texture: Broadloom is more often available in plush, cut-pile, and patterned-loop constructions that read more luxurious. Carpet tile leans toward lower-profile loop constructions that read more commercial.
Replaceability: Where Carpet Tile Wins by a Mile
The single biggest reason carpet tile dominates commercial offices is replaceability. A spill, a stain, a worn traffic path: with carpet tile, you replace the affected tile. With broadloom, you replace the floor. For most occupied SF tenants this is the single biggest driver behind choosing tile, and it is the same reason our commercial carpet team recommends tile for nearly every open-plan workspace.
Spot replacement: When a section of carpet tile gets damaged, you lift it and drop in a new one. The repair takes 15 minutes. If the original installation kept extra tiles on hand (we recommend 5 percent overage stored on site), the replacement matches perfectly.
Reconfiguration: Offices move. Workstations migrate. Conference rooms get added. With carpet tile, you can pull tiles up to access subfloor for cabling and put them right back down. Broadloom requires cutting, re-seaming, and often re-stretching, which usually looks worse than starting over.
Phased replacement: A 10-year-old broadloom floor with worn high-traffic paths typically requires full replacement to look right. The same situation with carpet tile can be addressed by replacing just the worn tiles, extending the floor's life by years.
Installation Speed and Disruption
Modern offices rarely close for flooring. The install needs to happen around tenants, sometimes after hours, often in phased zones.
Carpet tile install: Crews can install carpet tile at roughly 1,000 to 1,500 square feet per crew per day in a typical office. The dry-back format means no wet adhesive curing time, so areas can be walked on and furniture reset immediately. Carpet tile is the right choice for tight occupancy schedules.
Broadloom install: Broadloom requires longer install times, often with stretched-in or glue-down methods that need cure time. Roll handling in tight elevators and corridors is its own logistical challenge in SF high-rises. Allow more days and plan for furniture to be off the floor longer.
After-hours installation: Both products can be installed after hours, but carpet tile is much more forgiving when crews need to leave a space ready for next-morning use.
Cost Per Square Foot
Carpet tile and broadloom land in overlapping but distinct price ranges. Most projects in San Francisco see these realities.
Carpet tile installed cost: Typically $5 to $12 per square foot installed for commercial-grade product. Premium designer collections (think Bentley, Interface flagship lines) can run $14 to $20 installed. Material is usually the larger share of the bid.
Broadloom installed cost: Wider range. Mid-grade commercial broadloom is $4 to $8 installed. Premium hospitality-grade broadloom can run $15 to $30 installed for plush cut-pile or custom patterns. Custom dyed broadloom for executive spaces is its own price tier.
Sample bid math: A 5,000 sq ft office floor in commercial-grade carpet tile typically lands $35,000 to $60,000 installed. The same floor in mid-grade broadloom runs $25,000 to $50,000. The same floor in premium broadloom can exceed $100,000.
Lifecycle Cost and Maintenance
Initial cost is not the same as 10-year cost. Replaceability changes the math.
Replaceable wear surface: Carpet tile's spot-replacement capability means the average tile across the floor can last 15 to 20 years even if some tiles get replaced multiple times along high-traffic paths. Broadloom typically reaches end of life at 7 to 12 years.
Maintenance programs: Both products benefit from regular vacuuming and periodic deep cleaning. Carpet tile is somewhat easier to extract because seams help break up cleaning patterns. Broadloom in large open spaces can be cleaned in one continuous pass but requires moving more furniture.
Total 10-year cost: For most commercial offices, carpet tile lifecycle cost is lower than broadloom lifecycle cost even when initial cost is higher. The crossover is in spaces where appearance is paramount and the floor will be replaced for aesthetic reasons before it wears out.
When Each Is the Right Call
Use this as a fast decision rule. If you want a recommendation tailored to your floor plate, request a carpet estimate and we will walk it with you.
Choose carpet tile for: Open-plan offices, workstations, hallways, training rooms, IT-heavy spaces with under-floor cabling needs, any space where reconfiguration is likely, and any project where replaceability matters more than seamless aesthetics.
Choose broadloom for: Lobbies, executive suites, conference rooms, board rooms, hospitality spaces, senior living common areas, and any project where the carpet is part of the design statement and the budget supports a higher-end finish.
Mix the two: Most modern offices use both. Broadloom in the lobby and main conference room. Carpet tile everywhere else. This gives you the design statement where it matters and the replaceability where it counts.
Frequently Asked Questions
Can I install carpet tile myself to save money?
Technically possible for small areas. Not recommended for commercial installations of any meaningful size. Commercial-grade carpet tile requires specific adhesives, subfloor prep, and seam alignment that an untrained installer will miss. The cost of fixing a bad install usually exceeds the labor savings.
How long does commercial carpet last?
In a typical commercial office, expect 7 to 10 years for broadloom and 10 to 15 years for carpet tile, with proper maintenance. High-traffic areas like entries and elevator lobbies wear faster regardless of format.
Is broadloom outdated for offices?
No. Broadloom has a specific role in commercial design. It is not the everyday answer for open-plan workstations, but it has not gone away. The current trend is toward broadloom in high-design areas paired with carpet tile in functional areas.
Can carpet tile be installed over existing flooring?
Sometimes. Over VCT or other hard, level, fully bonded surfaces, yes. Over existing carpet, no. Over flooring with moisture issues, no. Always require a moisture and substrate test before assuming you can skip removal.
What about carpet plank? Is that just carpet tile in a different shape?
Yes, essentially. Carpet plank is carpet tile in a longer rectangular format (typically 18 by 36 or 12 by 48). The installation method, replaceability, and use cases are the same as standard square carpet tile. The longer format reads slightly more contemporary.
