“Floating vanities are trendy, but in a small bathroom they create a maintenance problem: the exposed floor gap under a floating vanity collects hair and soap scum in spaces that can't be cleaned with a standard mop. For a bathroom under 60 sqft, I usually recommend a floor-to-counter vanity instead.”
If your bathroom is above grade (second floor), specify a floor pan (waterproof membrane with a secondary drain) under the tile shower. A floor pan prevents water intrusion to the ceiling below if the primary waterproofing ever fails. It costs $400–800 and is standard practice for second-story bathrooms in quality construction.
Most bathroom remodeling projects in Brentwood that involve structural, electrical, plumbing, or mechanical changes require LADBS permits. Working without required permits in Brentwood creates unpermitted improvement disclosure obligations at sale. Your contractor should pull all required permits before work begins — this protects both your investment and your legal standing.
Verify CSLB license at cslb.ca.gov, request 3+ references from completed bathroom remodeling projects in Brentwood or nearby, confirm active insurance and worker's comp coverage, and ensure the contractor can explain the permit process for your specific project. Contractors who know Brentwood's local conditions, permit office staff, and inspection procedures complete projects faster with fewer complications.
