Common mistakes (and how to avoid them)

Skipping ventilation or waterproofing details because they aren’t visible.

Starting demo before selections are finalized (tile/cabinets/fixtures lead times matter).

Comparing bids without aligning scope, allowances, and exclusions.(See also: bathroom remodeling in La Jolla)

Underestimating how much layout changes impact plumbing/electrical and budget.

Forgetting storage and workflow—designing for photos instead of daily life.
