How did he manage it? Don't worry… Brad has his own version of events. 😂
Elsewhere on the build:
🔥 Bathroom underfloor heating goes in
🔧 Sam is forced to step in and help the plumbers
😂 We discover just HOW LONG the plumbers have actually been onsite
🏠 Roger starts installing the coving
💦 Brad shows us how we're using Laticrete Hydro Ban waterproofing
