What floor for a garden room?

[Gozogozo]

I have a newly built garden room with a concrete floor. It takes you from the rear service alley into my garden. It is used mainly for storage.

I am stumped about what floor to use. Vinyl cushioned will damage easily if boxes etc are dragged across it & LVT like karndean way too expensive.

It needs be moppable due continual mud being traipsed through.

How would tiles be? Generally not a fan due to grout issues but I guess if I had them sealed from the start, it might not be so bad? What size, given a not perfectly level concrete floor?

Any ideas would be really helpful.

If its only a storage room, not a posh room that people see, why not just paint the concrete?
Originally these sort of rooms would have had quarry tiles.

Thanks. It's not perfectly smooth & I can see it being a pain to mop, but hadn't thought of that.

Dont know it you can get this product in UK, I guess the work is in the preparation of sanding and jetwashing the floor, but it looks great
