May I suggest contacting the interior designer to request information on the tiles?

Hi Micshak, No, you're not argumentative at all - your frustrated and understandably angry about your experience and are coming from that place. I didn't say that there weren't minimums, I said that rectified tiles allowed finer than traditional grout lines. Happily for me, I've had a similar issue to Stacey and were fortune to have great building team who ensured that my problem was fixed as soon as I raised it with them and they covered fixing the issue and resulting damages from their pocket - it wasn't even a conversation topic - what I got was "absolutely, yeah, that needs to be fixed, no worries" - the difference between great people and the guy you sadly got. Your story almost bought me to tears but did bring home the advice I had from more experienced family members on personally checking license and trade affiliations such as HIA and checking the trades insurances as well as being on site every day and only paying when I was happy for the job. It goes to show - just because you're a good person, doesn't mean that everyone you meet is a good person. Know that I believe that poor tradesman and badly behaved tradesman who don't produce reasonable quality work should be publicly flogged and branded because of the heartbreak, stress and financial hardship they put people through. Stacey needs to be able to give the option of having the problem fixed and the tiler/builder the chance to regain his reputation before trying to fix things yourself - despite your horrible experience, most are tradies are hardworking good people and want to do great work for you to keep good will for their business. Sadly for you anyone who is going to prohibit this man from getting work/money isn't going to do much except be background noise. Davco, the tile supplier etc aren't able to stop him from getting work - but you sure can and I'd encourage you to go after him with unrelenting vengeance) - go to the appropriate licensing board and talk to them. Go to HIA if your tiler is a member and the Fair Trading body in your state as a matter of course - they should be able to force compensation. I would threaten to get on every website, blogsite (including TrueLocal), the local paper and social media to tell as many people as you can about your experience with this tradesman naming names and showing what appalling work was done if you don't receive a refund/compensation/a first class quality fix within 14 days - and then if you're not happy follow through with the shaming and make sure he knows about it by sending him links/snapshots/clippings naming him and his business and let him know you're so upset that this will continue to be refreshed on a monthly basis until you receive satisfaction or he's out of business. If he indicated any businesses or people that would recommend him or gave you a list of previous jobs, I'd be sending letters to them (with photos and supporting correspondence) letting them know - and copying him. Builders all talk ;) Oh - and you could always do what a friend of mine did - have friends ring the gentleman in question to book work then cancel at the last minute after you've done your shame campaign siting the fact that they heard that he was a shameless, substandard tiler and their going with a more reputable tiler. Evil, but no more than than deserved. Stacey - I honestly hope you have more my experience than poor Micshak's. Let us know how you get on.

thanks to everyone for your helpful comments! I was going to have to pay around $190 for 6 more, but will order them from Beaumont who have a 25% sale on at the moment. I agree that I need to just live with the cost and finish the job properly, but your shortcut suggestions were all really interesting and much appreciated. And archimondo, I'd say it's like having a kangaroo loose in the top paddock.

Looks like the same tiles we used on our bathroom floors, a few walls, pool coping etc
