Quoted a small bathroom remodel at $12k all-in (~$2k materials), based on ~80 sq ft subway tile walls and ~40 sq ft standard 12x12 floor tile. Client knew this and paid a deposit. This also includes paint and new toilet. No plumbing or electrical to be moved.
Now before start, she wants mosaic (12x12 sheets) on both shower walls and floor. Floor will be on slab after demo.
Obviously more labor, flatter prep needed, slower install.
How much would you add for this change? Flat add or wait until demo to see what I will be working with.
