Ceramic or porcelain tile will do very well. Laminate can "puff and die" inside of 6 months! I've seen it. It isn't pretty. The closest you will get to "click together" flooring = 100% vinyl flooring. The vinyl is water proof...the joint is not. There is still a chance that moisture (water or humidity) will reach the subfloor and begin to rot it out from underneath the floor. Be safe = ceramic or porcelain tile properly installed. I think you can work with a cooler tone in the bathroom. One of the design benefits with bathrooms is they can have their own "presence" in a home. They do not need to be identical to the rest of the home. They can carry the theme...but they are allowed their own flare. Go with something that is visually interesting. It can be a breath of fresh air if the rest of the home "all one look".

Or this, which is fairly similar to the effect you're looking for, but at a much lower price: https://www.victorianplumbing.co.uk/aspect-black-ivory-patterned-floor-tiles-331-x-331mm?FT=5898&pgno=1 Anyway, in these styles there are options galore :-)

If youre not sure, keep it cheap. These two are just nice sheet vinyl. Both look great and cost peanuts. If. You don't like it in the future or you'd rather something else, it's super inexpensive and some great choices available online

Hi Dundrum, sorry I don’t think grey would go at all, It was more to show you the variety of styles in vinyl rather than the colour. Here’s some more appropriate, warm shades, creams and beiges as well as wood effect. If you have time, visit a flooring shop and you will see 100s of examples, that’s what I did. I did also choose a Moroccan patterned vinyl below, but I’m not sure the shade is quite right? I really like the first dark wood effect one.
