Thanks for suggestion. This pinkish does match the colour in the tiles... And the little ones toilet seat :-) Taking a look via Google Lens.... See what comes up

Hi Kim, your bathroom looks pretty compact, so my humble suggestion would be to tile only the bath/shower section and leave the other walls free of tiles - it will make the space look bigger and brighter. And maybe you could have the metro tiles laid vertically to give the space a bit different look rather than going for the usual horizontal pattern. I'd then look for some feature tile as a splashback behind the basin to add some variety. Hope it helps, but feel free to reach out to me if you'd like to have a chat about it. Best regards, Anna

It’s common for tiles to be slightly bowed. For this reason this brickbond layout of tiles is very unforgiving for these large tiles because you have lined up the edges that are bowed in with the middle that is most bowed out. Had they been small tiles you wouldn’t have noticed but the effect is exaggerated with large tiles. That’s why the manufacturer recommended an offset brickbond laying pattern. 90/10 would have looked great. Given your efforts to convey this instruction to the tiler it’s disappointing that a professional who should know it’s not recommended to lay large tiles 50/50 brick bond to avoid exactly this situation went and did it anyway. I think the tiler is liable because even absent your instruction he should have known better. It’s professionally embarrassing that he has done it. I think the contractor also shared some responsibility if they hired the tiler. Basically it’s their recommendation, their reputation that is being damaged by poor workmanship and their relationship with you that is at risk. Consider the paper trail - did you get a quote directly from the tiler or through your contractor? It may be that you get nowhere but you should try to get the tiler to accept responsibility. After an firm conversation you need to write to him to outline what you feel is his fault and clearly stating what you expect him to do in return (such as replace all the tiles). You also need to state a timescale for response from him. If you can get it changed on his dime then happy days. If you have to pay for it you might conclude that you can’t live with it. Personally I wouldn’t spend the money a second time myself and I would live with it.

Thanks for the advice everyone. The walls are just plastered at the moment, so I'm thinking to paint them a shade of white first to get a better idea of how the space looks, then decide on some tiles. It's difficult to picture with how it is at the moment! I do like the idea of having white zellige tiles placed vertically, but worried it might look a bit busy if it goes from the countertop to the ceiling.
