Of course the point about Duravit’s DuraSquare range is the fact that if you look closely, it isn’t actually square. In that regard, it’s a bit like the Lutyens’ Cenotaph in Whitehall, which most people assume is rectilinear until they find out that its sides are subtly curved to a radius of 1,000ft. Of course, that’s where the resemblance ends; the latter honouring the glorious dead while the former merely indulges the living. That said, the range, including this deep bath, is formed of DuraCeram, a weighty, mouldable ceramic material than can taper to a rim of no more than 5mm without any deflection from a reclining back. If your luxuriant soak is making you feel slightly guilty, spare a moment’s thought for those who endured the waterlogged trenches of the First World War.
