Frequently Asked Questions

How do I measure for a countertop?
Measure the length of each counter section in inches. Standard depth is 25.5 inches. Multiply length × depth, convert to square feet (divide by 144). Add all sections together for total area.
How much do granite countertops cost?
Granite: $40-100 per sq ft installed. Level 1 (basic): $40-55. Level 2 (mid-range): $55-75. Level 3 (premium): $75-100+. Exotic slabs can exceed $150 per sq ft.
What is the standard countertop depth?
Standard kitchen countertop depth is 25-26 inches (including a 1.5-inch overhang). Island countertops are often 27-28 inches. Bathroom vanity tops are typically 22-23 inches deep.
How much countertop overhang for seating?
Standard eating bar overhang is 12-15 inches. This allows comfortable seating with standard counter-height stools. Support brackets are needed for overhangs greater than 10-12 inches depending on material.
What countertop material is most durable?
Quartz is the most durable — non-porous, scratch-resistant, and maintenance-free. Granite is very durable but requires sealing. Butcher block needs regular oiling. Laminate is affordable but less durable.
How are countertops priced?
Most countertops are priced per square foot. Quotes typically include material, fabrication, edge profile, cutouts (sinks, cooktops), and installation. Get itemized quotes to compare accurately.
What edge profiles are available?
Common edges: eased (slightly rounded), beveled, bullnose (fully rounded), ogee (S-curve), and waterfall (runs down the side). Simple edges are included in the base price; decorative edges add $10-30 per linear foot.
How long does countertop installation take?
Template measurement: 1 visit. Fabrication: 1-3 weeks. Installation: typically half a day. Total timeline from template to completion is 2-4 weeks for natural stone and quartz.
Can I install a countertop myself?
Laminate and butcher block are DIY-friendly. Granite and quartz are very heavy (15-20 lbs per sq ft) and require professional fabrication and installation. Improper handling can crack expensive slabs.
How much waste is there in countertop fabrication?
Natural stone slabs have 20-40% waste depending on the layout. Simple L-shaped kitchens have less waste. Complex layouts with many cutouts create more waste. Quartz is similar. This waste is built into the per-square-foot price.
