Thanks for all the comments....
To answer a few points:
I never tried to save money. I actually tried to get 6 quotes for the job. Ended up with 3 quotes. The guy I used was not the cheapest but could do it when we had time off work originally (although this did not work out). The guy I wanted to do the work actually blew me out completely. Another
tiler only guy couldn't do it for many weeks after when we wanted. I guess now this is a sign of a busy good
tiler. But things are great in hindsight.
Regarding B&Q tiles, I am no expert. I have no idea what is a good place to get tiles and which isn't. I can see from the responses that B&Q are not seen in high regards and I will definately bear this in mind in future. I will actually take the floor tiles back before they are laid! Please recommend a good
tiler and a good tile store!?
Regarding pictures, I will try and post some. I need to recharge my camera battery and will put some on later.
Also regarding noticing the variations before laying. I must admit I didn't notice seeing variations before grouting. But after grouting it is distinctly obvious. Now I can see the variations in the ones that are still to be grouted....So now that I am aware and trained my eye to look for variation I can see. But again this is a learning curve for me.
I do take the points regarding mixing the tiles up, as I think if this happened the varying tiles would have been blended in and not noticed!
Thanks again.
