Finally, in the group challenge, one candidate acts as the reluctant foreman to conquer a framing challenge - a frame that will be used in the construction of the Ice Hut.

As our five hapless home renovators continue their stint in rehab, they find themselves building a medicine cabinet that is meant to be both attractive and functional.

As the handymen begin smashing their way toward rehabilitation, it’s clear that they’ve got a long road ahead. First, they design their rooms. Then their skills – or lack thereof – are assessed as they build stud walls and install wall safes in each room. Or attempt to! By the end of the episode, one candidate breaks through the rubble to claim the title of “Most Improved.” In the end, however, incompetence ensures that someone else is nailed with the title of “Worst” after the first round of projects.

When the production team visited the handymen at their respective homes, they noticed that none of the handymen had functional workbenches. Well actually, Desmond did – until he used it and cut right through it with a circular saw. Now, each handyman is charged with designing and building their own workbench – but the results are dubious at best! Next, see how Reno Rehab is driving these handymen up the walls – quite literally.

As they soldier on, the handymen must also dig deep in order to correctly fix the holes in their floors, but many find themselves on shaky ground. Even hanging mirrored panels on the wall proves to be too much for this band of bad builders. Finally, for the group project, the team attempts to install flooring and cabinets. At the end of this episode, one person is named the most improved, and yet another is named this episode’s worst.

Things unravel quickly, however, and many rooms are lucky to get any form of curtain hung at all. Next, the crew attempts to tackle basic closet construction and hanging wall sconces. What should be fairly simple for an average handyman proves nearly impossible for most of these hopeless renovators. In the kitchen, work continues – as well as the arguments, struggles and blunders.

The Handyman Rehabilitation centre offers a new set of challenges this week that include learning to make a tufted headboard and fixing a banister. Things really get switched around, however, for the group’s kitchen challenge as this episode’s foreman takes on grouting and then tackles the backsplash… with more than a little backlash!

Everyone builds a stereo unit and installs a TV, but it soon becomes apparent that one of the group members is a weaker link than previously suspected.

After learning proper harness techniques, the handymen tackle the roofs of their eco sheds. Roofing proves to be too much to handle as a few teams reach the end of their ropes. Other pairs, discouraged by the results, head for the floor. Then it’s time for the final step as doors are installed on each of the sheds.

The completed sheds are revealed for their final evaluation. Which of them will fit through the warehouse door? Everything comes to a head as this season’s Worst Handyman is named, once and for all.
