What can I put on top of tiles?

[Hangfail]

I had floor tiles laid in my guest toilet and utility room and I hate them! Well, I actually like the tiles themselves but they don't work for me - they're very hard to keep clean, already look grubby and are cold underfoot

I can't afford to get them removed but thought perhaps I could lay something on top of them? Would that be possible? And if so, any suggestions please? Thank you :)

Just a word of warning on these floor pops, we made a costly mistake with our downstairs toilet - pale pink tiles with pale grout, they wore terribly. Covered with floor pops - wee (after a big party) went under the floor pops and absolutely stank, I had to rip them all up, even though it looked like there were no gaps. We ended up just getting the tiles replaced in the end but make sure they are properly sealed especially in the toilet area.

I was hoping to avoid this but think it's the only viable option.

Great work @Hangfail
