Kitchen Island Cost by Component Guide
The component layer prints by unit: cabinets per linear foot, countertops per square foot, and sink, cooktop, and outlet hookups each on their own lines, in two frames kept apart.

The component layer, priced apart in both frames
| Component line | Frame A band | Frame B band |
|---|---|---|
| Cabinets, per linear foot | $100-$1,300 | $500-$1,200 |
| Countertops, per square foot | $20-$350 | $50-$150 |
| Sink | $400-$1,500 | $380-$1,400 |
| Faucet | $125-$300 | $120-$250 |
Every figure here sits inside its own frame, never averaged. Frame A prices the component layer beside its project totals; Frame B prices the same layer as per-unit lines beside its average range. The project whole prices on the kitchen island hub; the form layer on the prefab vs. custom guide.
Cabinets per linear foot, as published in both frames
| Cabinet line, as published | Frame | 2026 band |
|---|---|---|
| Cabinets, per linear foot | Frame A | $100-$1,300 |
| Cabinets, per linear foot | Frame B | $500-$1,200 |
| Stock cabinets, per linear foot | Frame B | $100-$400 |
| Semi-custom cabinets, per linear foot | Frame B | $150-$700 |
| Custom cabinets, per linear foot | Frame B | $500-$1,200 |
The cabinet layer carries the widest spread in either frame. Frame B breaks its line into three named tiers, stock, semi-custom, and custom, each on its own line. Frame A prints one cabinet band, read apart and never merged with any Frame B tier.
Countertops per square foot, as published in both frames
| Countertop line, as published | Frame | 2026 band |
|---|---|---|
| Countertops, per square foot | Frame A | $20-$350 |
| Countertops, per square foot | Frame B | $50-$150 |
| Sink, installed line | Frame A | $400-$1,500 |
| Sink, installed line | Frame B | $380-$1,400 |
The countertop layer prices by area rather than by length, and the two frames print different bands for it: $20 to $350 per square foot in Frame A against $50 to $150 in Frame B, side by side and never averaged. The sink line prints beside the countertop lines in both frames, as its own component line.
Fixture and appliance hookup lines, as published
| Hookup line, as published | Frame A band | Frame B band |
|---|---|---|
| Faucet | $125-$300 | $120-$250 |
| Dishwasher | no line printed | $600-$1,700 |
| Garbage disposal | no line printed | $200-$500 |
| Cooktop | no line printed | $500-$1,600 |
Frame B names the fuller hookup layer here: dishwasher, disposal, and cooktop lines beside the sink and faucet lines. Where Frame A prints no separate line for a named component in the grounded data, that absence prints as published, with no invented band claimed.
Utility hookup lines, as reported cost lines only
| Utility line, as published | Frame A band | Frame B band |
|---|---|---|
| Plumbing lines | $500-$1,900 | $450-$1,800 |
| Electrical wiring, per linear foot | $7-$12 | $7-$10 |
| Outlets, each | $150-$400 | $150-$350 |
| Gas lines, per linear foot | $15-$30 | $15-$50 or more |
Each utility line reads as its own reported cost category: the plumbing line a sink or dishwasher hookup names, the wiring and outlet lines a cooktop or outlet hookup names, and the gas line a gas cooktop hookup names. No line here is a procedure, and no utility band folds into a component band.
- Component named beside every band
- Frame named on every line: project-total or per-unit
- Cabinet tiers shown apart inside Frame B, never merged
- Utility lines read apart from component lines
