Square ceramic bathroom tiles are long gone but finding the elusive "something different" without resorting to a trend you'll be sick of in six months isn't easy.
Although you may have seen something similar before, Fired Earth in Dublin supply "pebble" tiles for bathroom floors or walls. The black, grey or soft pink stones are embedded in plaster and come in 26cm square sheets but look like one piece no matter how you use them. The look is organic but they aren't too earthy.
You wouldn't want to be too environmentally minded to buy them - visitors to your bathroom might say that some beach in Indonesia has been robbed of pebbles. €164 per sq m or €12 per tile. Fired Earth, 31 Lwr Ormond Quay, Dublin 2.
