Here’s a detailed, data-backed overview of how much it costs to install a sports-grade wood floor (like a maple gymnasium or basketball court):

📏 Installed Cost of Sports-Grade Hardwood Flooring

According to gym-flooring specialists, maple hardwood courts typically run between $12 to $26 per sq ft installed (materials + labor).
The exact price depends heavily on wood grade (first-, second-, or third-grade maple), subfloor type, and design:

• 1st-grade hardwood: $11.50–$14 material + $4.50–$6 installation → $16–$20+/sq ft

• 2nd-grade hardwood: $9.50–$11 + $4–$5.50 installation → $14–$17/sq ft 

• 3rd-grade hardwood: $7.50–$9 + $3.50–$5 installation → $11–$14/sq ft

🏢 Full-Court Example Costs

For standard court areas (≈5,000 sq ft):

• Material: 5,000 × $5–$8 = $25K–$40K

• Labor/Subfloor/Prep: 5,000 × $3.50–$6 = $17.5K–$30K

• Total: $42.5K–$70K 

Larger courts or high-end specifications may reach up to $184K .

🔁 Maintenance & Lifecycle Cost

• Annual maintenance (cleaning, recoats): $0.75–$1.25/sq ft/year → for a 5,000 sq ft court: $3.8K–$6.3K annually 

• Resurfacing / refinishing every 7–10 years: $3–$8/sq ft → $15K–$40K on a full court

For comparison:

• Synthetic sports floors: $10–$22/sq ft installed

• Modular tiles or vinyl: $4.50–$15 depending on material best suited for multipurpose usage
