This cast-iron bath is the focal point in a lofty bathroom flooded with natural daylight.      A fruit picker&#x27;s ladder is in use as a towel rail, painted in Farrow &amp; Ball&#x27;s Lamp Room Gray (88) to match the bathtub. An old wicker basket housing fresh towels sits in the fireplace, and a collection of Victorian engraved mirrors on the wall encircles an early 19th-century tin clock.
