    Kitchen is half quarry tiles / half concrete... what do we do?

    I've just got up the old carpets on our renovation project, and weirdly the kitchen floor is mostly quarry tiles, except for the back third of the room being concrete.

    Preparing old Concrete floor for tiling (ed.)

    Hello We removed old vinyl tiles from our bathroom floor and scraped it as much as we could. It's still left the old adhesive in some patches. It's quite thin though. Is it ok to tile over using porcelain tiles or do we need to prep it further?

    Is 600mm too high for a bath? Builder has just raised mine on bricks...

    In a complete bathroom rebuild, my bath has just been replaced in its old spot (well, the new shower enclosure is 30cm wider so it is 30cm to one side of its old spot). They have put the bath's feet on bricks so they could attach the waste - so the whole is now at least 7cm higher than it used...
