How Much Should a 20x20 Kitchen Remodel Cost?

Quick answer

A 20x20 (400 sqft) kitchen in Palm Beach County typically falls at the upper end of standard remodel ranges. Expect $30,000–$45,000 for a complete mid-range remodel, $60,000–$100,000+ for high-end finishes, and $120,000+ for a luxury gut renovation. The size pushes you up within each tier because there are simply more linear feet of cabinets and more countertop slabs to fabricate.

A 20x20 kitchen sounds like just a number, but it changes the math on a remodel meaningfully. At 400 square feet, you've got more linear feet of cabinets, more countertop area, more flooring, more lighting, and usually a larger island — all of which push costs up within whatever budget tier you pick.

Why size matters more than square footage

Most contractors don't price kitchens by the square foot — the cost driver is linear feet of cabinetry, which scales with the perimeter of your room and how much wall space gets cabinets.

A typical 20x20 kitchen has:

• 30–45 linear feet of perimeter cabinets (vs. 15–20 in a small kitchen)
• A large island — often 8–12 linear feet with cabinets on one or both sides
• 40–55 sqft of countertop area (vs. 20–25 in a small kitchen) — often 2 slabs
• ~380 sqft of finished floor area (subtracting cabinet footprint)
• More electrical runs, more lighting points, more plumbing if you're moving the sink

All of which is to say: a 20x20 kitchen costs roughly 1.5–2x what a 100-sqft galley kitchen costs at the same finish level. You're not paying for sqft — you're paying for material quantity and labor hours.

20x20 kitchen costs by tier in Palm Beach County

What a $40K 20x20 mid-range kitchen looks like

This is the most-installed configuration in our larger Palm Beach County kitchens — common in Wellington, Palm Beach Gardens, and Jupiter family homes:

• Highland White Shaker or Fabuwood Tuscany semi-custom cabinets — approximately $13,000–$16,000 for the cabinet package given the linear feet
• Quartz countertops — 2 standard slabs or 1 jumbo, approximately $4,500–$6,500
• Large island with seating for 4 (often 10–12 linear feet)
• Mid-tier appliance package (KitchenAid, Bosch, GE Profile) — $5,000–$8,000
• Large-format porcelain tile floor (380 sqft) — $4,000–$6,000 installed
• New lighting plan — 8–12 recessed cans + 3 island pendants + under-cabinet LED
• Backsplash, plumbing fixtures, hardware — $2,500–$3,500
• Installation labor and cleanup — $5,000–$7,000

Total: roughly $40,000–$45,000 installed. That's a complete kitchen transformation with finishes that hold up well to daily family use. Permits, if required for your specific project scope, are handled by your general contractor as part of their separate scope.

What a $75K–$100K 20x20 high-end kitchen looks like

High-end is where 20x20 kitchens really shine — the size lets you specify custom touches that would feel cramped in a smaller space:

• Custom or top-tier semi-custom cabinetry with painted finishes, soft-close everything, integrated trash pulls, and customized organization — $25,000–$40,000
• Premium quartzite or marble-look quartz on a jumbo island slab + perimeter — $8,000–$15,000
• Premium appliance package (Wolf, Sub-Zero, Thermador, or Miele) — $15,000–$25,000
• Designer lighting with statement pendants — $2,500–$5,000
• Hardwood or premium engineered floor — $6,000–$9,000
• Custom range hood, panel-front fridge integration, or built-in coffee station — $3,000–$8,000
• Tile backsplash with custom pattern or full-slab quartz backsplash — $2,500–$4,500

Total: $65,000–$100,000+ installed, depending on appliance package and material grade.

What gets more expensive in a 20x20 kitchen

Cabinets scale almost linearly with linear feet. If a small kitchen with 18 linear feet of cabinets costs $9,000, a 20x20 with 40 linear feet costs roughly $20,000 in the same finish. The unit cost per linear foot stays similar, but the quantity doubles.

Countertops cost more in larger kitchens not by sqft but by slab count. A small kitchen needs one standard slab. A 20x20 often needs two slabs or one jumbo. Beyond just the material, this means more layout planning, more seam discussion, and bigger fabrication waste. Picking your specific slabs at the yard becomes more important — vein-flow continuity across seams matters.

Flooring scales by sqft. 400 sqft of porcelain at $10/sqft installed = $4,000. 400 sqft of real hardwood at $13/sqft = $5,200. Doesn't change the tier, just the absolute number.

Lighting plans get more involved. A 20x20 kitchen needs 8–12 recessed cans (vs. 4–6 in a small kitchen) and more circuits to handle the additional pendants, under-cabinet LED, and island work. Electrician hours go up.

What does not scale with kitchen size

Some costs stay roughly fixed regardless of kitchen size:

• Permitting and inspection fees (when needed — handled by your general contractor)
• Demolition (a little more for bigger kitchens, but not 2x)
• Single-item appliances (one range costs the same whether the kitchen is 100 or 400 sqft)
• Project management hours

This is why a 20x20 kitchen doesn't cost 4x what a 100-sqft kitchen costs — just 1.5–2x at the same finish level.

How Palm Beach County location shifts the number

Boca Raton and Palm Beach Gardens typically push 20x20 kitchens to the upper end of every tier — buyers expect custom cabinetry and natural stone in homes at the neighborhood comp range. A "mid-range" 20x20 here often ends up at $45,000–$60,000 because of finish expectations.

Jupiter and Wellington are the sweet spot — $40,000–$55,000 delivers a 20x20 kitchen that photographs well and appraises strongly.

Lake Worth, Greenacres, and Lantana support more value-conscious 20x20 remodels — $30,000–$40,000 delivers a great-looking kitchen without overcapitalizing relative to neighborhood comps. NKBA's kitchen planning standards apply equally across all markets — the difference is finish level, not design.
