We took up the lino in our little under-the-stairs bathroom after our leak at Christmas. And since then it was just plain concrete floor.
Which had to be remedied before the party on Sunday as we couldn't have so many visitors using that bathroom and it looking so bad! So I bought some self-adhesive tiles and stuck them down.
Its not a great job, and probably won't last too long, but it did for the occasion and might last for a little while.
