Four teams of seasoned builder-designer duos start the epic task of transforming four lakefront cabins into gorgeous vacation rentals.

There's no time to relax at Renovation Resort, as the competition moves into the living room; a fun fishing trip inspires Scott and Bryan to surprise the teams with a task that pays tribute to the resort's history.

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.

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.

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.

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.
