“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.
The most common bathroom remodeling mistakes in Hidden Hills are: selecting a contractor based on price alone without verifying CSLB license and insurance, approving change orders verbally rather than in writing, and starting work before permits are issued. All three create financial and legal exposure that's avoidable with careful contractor selection and contract management.
