As Round 3 in this Brother Vs. Brother challenge gets underway, the score is tied — with the living room challenge having gone to Drew and Jonathan having won the kitchen competition.

Bristol and Aubrey Marunde, hosts of Flip or Flop Las Vegas, are on hand to pick a winner in the battle of the main suites. "Aubrey and Bristol are experts when it comes to flipping houses," said Jonathan. "They flip houses in Las Vegas and I love the fact that they're here to judge our main suites."

Drew visits San Francisco's Fireclay Tile to select a specialized tile that he hopes will give him the edge in the creation of a winning main bath.

For his main bath, Drew went with a modified hex floor tile in peacock blue to help create a visually striking design. "Jonathan always tries to one-up me with tile," says Drew, "but this time I think I've got him beat."

Main Bedroom, Before. Structural constraints prevented Drew from adding square footage to his bedroom suite, but his plan calls for making more efficient use of the existing space.
