Hi, they look like Little Diamond tiles from the Dwell collection by Heath Ceramics based in San Francisco. I know because I saw a picture of them and loved them and hunted them down! I even got them to quote for shipping to the UK but the cost was prohibitive for us sadly. If you're in the UK and find anything comparable, please let me know!

That's an awesome colour (I've used to great effect too in small places). It enables you to be really decadent and make the room mega luxury. Who doesn't want that sat on the throne ;-) I totally disagree with trying to match everything up, it's a complete waste of the palette in the colour itself, and don't worry about the curve stuff, work with it, put things into the space that make it enjoyable. Annoyingly I can't upload the pics I have sorry. The colour enables you to go crazy. Blacks, browns, grey (downpipe grey is the match for this colour and it is ace), purples, bronze, gold and silver all come to life off it. Please, please, please do not put any more white in there. Make it mega luxurious... To make the walls come to life you could use lots of photo frames in golds and silvers, do a mural around the corner of the wall above the basin with those small glass bricks and mirrors to create a focal point (think / look at morrocan style stuff), add in a really deep mix rug, put up a lush dried flower set that you can add scent to once in a while, get a shelf up for candles and trinkets. Enjoy going wild - you won't be diss-apointed when you're on the throne haha

When you say 'practically new' how long are ypu actually talking? Tiles tend to have a shelf life with suppliers of 3 years or so. So you may struggle to get them again. However, you would need to start with the usual suspects such as Topps Tiles, B & Q, Wickes etc before moving onto specialist suppliers. Good luck!

Be prepared to take out a second mortgage to pay for them!!! I spent a wonderful afternoon browsing around Chelsea Design Centre. The Ann Sacks store is glorious and more than a tad on the pricy side ;-)
