The figure above is an installed cost — material and labour together. We do not publish a material-only DIY figure for this project because our cost data does not separate the two here, and estimating it by assuming a labour share would be a guess rather than a source.

Interlock tiles
Puzzle-piece edges snap together — work row by row.

Safety Warnings
FAQ
How thick should home gym flooring be?
8 mm suits general fitness and cardio. 15–20 mm is the usual choice where free weights are dropped, and dedicated lifting platforms go thicker still. Under-specifying thickness is how you crack a slab or damage the subfloor beneath.
Can I put rubber gym flooring over carpet?
Over low-pile carpet, interlocking tiles will work but feel spongy underfoot, which is unhelpful for stability under load. Over thick or plush carpet, lift it — a soft base under heavy equipment is both a stability and a safety problem.
Will rubber gym flooring damage my garage floor?
Rubber protects the slab rather than damaging it, but it traps moisture underneath. On a garage slab that passes moisture, that can encourage mould at the interface — lift tiles occasionally to let it dry, or choose a mat with a textured underside that allows some airflow.
Do rubber gym mats smell?
New recycled-rubber flooring has a distinct odour that fades over several weeks. Ventilate the space, and if the smell is a dealbreaker choose vulcanised rubber or a PVC-backed product instead — the odour comes from the recycled crumb binder.
Can I install home gym flooring myself?
Yes — interlocking rubber tiles are designed for tool-free DIY installation. It's one of the easiest flooring projects available, typically done in a few hours.
