Recommendations for wall mirror tiles in the home gym?

I’m setting up my home gym and want to add a mirror to check my form during workouts. Full-length mirrors seem pricey and space-consuming, so I’m considering wall mirror tiles as an alternative.

My main concern is whether the gaps between the tiles are distracting or problematic for checking my form. Do you have any recommendations for specific brands or types of wall mirror tiles that minimize these gaps? I’d appreciate any insights or personal experiences you can share.

There are gym mirrors made from reflective plastic that are more affordable.

Do you have any recommendations for that?

Unfortunately, I don’t have any specific recommendations, just heard about them.
