I looked at a flat that had a sunken bath that was beside the route from the bathroom door to the toilet and considered it a death trap. Then a friend who is an engineer pointed out that, as this was the first floor flat in a house conversion, the sunken bath is either sticking out from the ceiling of the downstairs flat or, as was the case, it is in the stairwell which should have been capped off with very sturdy beams but instead has a bath in it. And the plumbing for the bath would, presumably, be through the now bricked off bottom of the stairs in the lower flat. It all looked like a nightmare and stayed on the market for a year, occasionally going off when someone made and offer and quickly coming back again when the surveyors report came in. Now at least I know it could have been worse.
