Badly installed tiles

[MrsSilenceDogood]

The tiles in our bathroom seem to have been installed badly. Some are not quite level and the grout appears to be failing. I removed one tile so I could see what substrate was used. How do I go about removing the tiles and preparing the floor for tiling? I'm a noob, so a detailed explanation would be great.

You would be better posting you enquiry in the 'Tiling' section of the forum where guys in the know about this sort of thing hang out. They are much less likely of see it here.

If you read the instructions for this forum called 'Your Projects' it states that it is not for Queries......

If you ask the moderators, they will move it for you. That way you won't have duplicate posts and fall foul of the forum rules.
