All four vacation rental cabins are completely transformed and the exhausted teams are surprised to discover that they have to compete, for one last time, in a rock the dock challenge.
With the interiors complete, Scott and Bryan get the teams to head outside to take on the exteriors; Rotem and Troy turn up the heat; Jena and Sean counter with another custom build; Savannah and Kyle encounter pergola problems.
To wrap up the interior transformation, Scott and Bryan task the teams with transforming the upstairs bedrooms and bathroom. Kyle makes a costly measuring mistake and April is forced to tackle the power tools.
In the fourth cabin challenge, Scott and Bryan serve up one of the most important rooms for a vacation rental: the kitchen! Savannah and Kyle get things cooking with a bold cabinet colour while Rotem and Troy have a crisis of confidence.
Creativity is put to the test in the third cabin challenge, as the teams head upstairs to turn the loft into a dual-purpose flex space; Savannah and Kyle create a family-friendly cosmic space while Rotem and Troy build a hidden room.
Scott McGillivray enlists builder and longtime "frenemy" Bryan Baeumler to help get his recently purchased, total wreck of a lakeside resort into shape. Although they won't be getting their hands dirty this time, instead, they're calling in four expert contractor/design duos who will battle it out against each other as they bring this forgotten fishing resort back to life in a frenzied, fun, action-packed competition series. Each of these super-skilled teams will design and renovate one of four waterfront cabins in just six weeks, attempting to transform them into gorgeous one-of-a-kind vacation rentals ready to receive flocks of guests.
