Overview: Ranvir Singh and Kunle Barker travel to Tamworth to meet Keira and Ewan in their newly purchased 1960s home. With a tiny budget they have allocated £3,000 to renovate their bathroom, yet they want a luxury hotel look. Their green makeover involves replacing a water-guzzling toilet and bath with money- and energy-saving fittings as well as creating a chic and contemporary finish. For inspiration, Ranvir heads to a house with a wood-fired hot tub.
