Ranvir and Kunle travel to Tamworth to meet young couple Keira and Ewan and their newly purchased 1960s home. With a tiny budget they have allocated £3,000 to renovate their bathroom, yet they want a luxe 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 eco-inspiration, Ranvir heads to a house with a wood-fired hot tub.
