All four vacation rental cabins are completely transformed and the teams are surprised with one last "Rock the Dock" challenge. This is their final chance to impress Scott and Bryan before the top team walks away with bragging rights and $100,000!

With the interiors complete, Scott and Bryan get the teams to head outside to take on the exteriors; Savannah and Kyle encounter pergola problems while April and Arnold struggle with their budget constraints.

To wrap up the interior transformation, Scott and Bryan task the teams with the upstairs bedrooms and bathroom; Rotem and Troy create a fun bunk-bed play space, and Sean runs on empty as he struggles with the execution of an unusual feature wall.

In the fourth challenge, Scott and Bryan serve up one of the most important rooms for a holiday rental: the kitchen; Savannah and Kyle get things cooking with a bold cabinet colour while Rotem and Troy have a crisis of confidence over storage space.

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.

There's no time to relax as the competition moves to the living room; a fishing trip inspires Scott and Bryan to surprise the teams with a task that pays tribute to the resort's history, but only one renovation style will reign supreme.

Scott and Bryan are lakeside in cottage country to kick off the renovation competition; under their watchful eyes, four teams of seasoned builder-designer duos begin the epic task of transforming lakefront cabins into gorgeous holiday rentals.
