17mm Rubber Gym Mats – Built for CrossFit & Home Gyms

900mm x 900mm (3ft x 3ft) · Interlocking Design · UK Stock

17mm thickness hits the sweet spot for CrossFit boxes and serious home gyms—thick enough to handle moderate barbell drops and functional training, whilst remaining affordable and easy to install. The large 900mm x 900mm (3ft x 3ft) format means faster coverage with fewer seams compared to standard 500mm tiles.

Why 17mm & 900mm Format?

17mm Thickness – The CrossFit Sweet Spot

17mm provides adequate protection for CrossFit WODs, moderate Olympic lifting (up to 100kg drops), and functional training without the cost of 20-30mm flooring. It's the thickness most CrossFit boxes choose for general training areas—not Olympic lifting platforms, but everywhere else.

900mm x 900mm Large Format

Each mat covers 0.81m² vs 0.25m² for standard 500mm tiles. That's 3x faster installation with 70% fewer seams. For a 3.6m x 3.6m area, you need 16 large mats vs 52 standard tiles. Less handling, cleaner appearance, faster setup.

Handles Moderate Training Loads

17mm works for barbell drops up to 100kg, kettlebell training, box jumps, burpees, and functional movements. It's not designed for heavy powerlifting or Olympic lifting platforms (use 20-30mm for that), but for general CrossFit training and home gym use, 17mm delivers solid performance.

Affordable Coverage

17mm costs 30-40% less than 20-30mm flooring whilst providing adequate protection for most training. For budget-conscious CrossFit boxes and home gym owners, this is the practical choice that doesn't compromise safety.

17mm vs 12mm vs 20mm – Which Thickness?

Bottom Line: 17mm is the sweet spot for CrossFit boxes and serious home gyms—adequate protection without premium pricing.

Technical Specifications

Real-World Applications

CrossFit Boxes – General Training Areas

17mm is the standard thickness for CrossFit box training floors (not Olympic lifting platforms). Handles WODs, barbell cycling, box jumps, and functional movements. Most boxes use 20-30mm for dedicated lifting platforms, but 17mm everywhere else to control costs.

Serious Home Gyms

For home gym owners doing CrossFit-style training, Olympic lifting practice (not max attempts), and functional fitness, 17mm provides adequate protection without the cost of premium flooring. Perfect for garage gyms and dedicated training spaces.

Functional Training Studios

PT studios, bootcamp facilities, and group training spaces benefit from 17mm's balance of protection and affordability. Handles varied training styles without the premium cost of thicker flooring.

Multi-Purpose Training Spaces

Community centres, apartment gyms, and multi-use facilities where training intensity varies. 17mm accommodates most activities whilst remaining budget-friendly for large area coverage.

Frequently Asked Questions

Can I use 17mm for Olympic lifting?

For practice and moderate loads (up to 100kg), yes. For max attempts and heavy Olympic lifting (150kg+), upgrade to 20-30mm. Most CrossFit boxes use 17mm for general training and 20-30mm for dedicated lifting platforms.

How many mats for a standard CrossFit area?

3.6m x 3.6m area = 16 mats. 4.5m x 4.5m area = 25 mats. Always order 1-2 extra for future replacements.

Why 900mm instead of 500mm tiles?

Faster installation (3x larger coverage), fewer seams (cleaner appearance), less handling. The trade-off is heavier individual mats (12kg vs 4-7kg), so two people recommended for installation.

Will 17mm work in upstairs home gym?

Yes. 17mm provides good noise reduction (70% dampening) for upstairs gyms. Adequate for moderate training without disturbing downstairs neighbours.

How long does 17mm last?

10-15 years with moderate use (CrossFit WODs, functional training, moderate weights). The 900 kg/m³ density resists compression and maintains performance.

The Bottom Line

17mm rubber gym mats in 900mm x 900mm format are the practical choice for CrossFit boxes and serious home gyms. They provide adequate protection for moderate training without the premium cost of 20-30mm flooring, whilst the large format means faster installation and cleaner appearance.

If you're running CrossFit-style training, functional fitness, or a serious home gym with moderate Olympic lifting, 17mm delivers the protection you need at a price that makes sense.
