Keith and Marj start renovations on the downstairs Sunday School so it can become their living space, complete with a kitchen, bathroom, bedroom and a snug. But before they can begin they have to rip out the fungus and try to control the dry rot that's infected the chapel.

Keith and Marj set their sights on turning the old school room into their snug. Marj restores a baroque French chair, while fellow Pottery Throw Down judge Rich Miller helps Keith to make brutalist tiles for a feature wall. The couple take a break from forging the chapel's future to visit the National Library of Wales to discover Capel Salem's fiery past.

Taking inspiration from Coventry Cathedral, Keith and Marj create a Victorian-style parlour bathroom, complete with a giant candlestick holder and Marj's dream lampshade.
