We spent this weekend fixing up the bathroom floor. Under the layers (cork tiles, glue and paint) we found nice reddish tiles. They are fine except the one in the doorway corner had a split in and wobbled.
I lifted half the tile and put some glue down to fix it. When I re-laid the tile it didn't sit quite right. I called my boyfriend but didn't wait for him, then stood on the tile... and heard it crack.
A small piece of hardened grouting had gone under the tile and was lifting the corner. When I stood on the tile it just cracked in half the other way! So now it has 2 cracks, but is glued firmly.
We're going to leave it as is - after all the work stripping the floor it can stay plain tiled for now.
It was quite a productive weekend. We have also replaced the flush thing in the toilet and it now flushes perfectly.
