“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.

A guest bathroom remodel takes 5-8 weeks. A master bathroom takes 8-12 weeks. Add 3-6 weeks for permits before construction starts. The waterproofing and tile phase is the longest single phase at 1-2 weeks.
Yes, if the remodel involves plumbing changes, electrical work, or structural modifications. A cosmetic refresh (paint, hardware, mirror swap) does not require a permit. Most bathroom remodels involve plumbing and electrical, so permits are typically required.
Waterproofing. Failed waterproofing causes the most expensive bathroom failures. Membrane waterproofing (Kerdi, RedGard, or similar) in all wet areas is essential. In LA, water damage claims average $12,000-$25,000 to repair. Never skip this step.
Yes, and it saves $3,000-$8,000. Keep the toilet, vanity, and shower/tub in their current locations and update finishes, fixtures, and tile. This is the most cost-effective approach for guest bathrooms and powder rooms.
