Do not skip waterproofing details

Showers, tubs, floors, corners, and transitions need careful waterproofing. Small shortcuts can create expensive moisture problems later.

Ventilation is not optional

Bathrooms need moisture control. Poor ventilation can lead to paint failure, odors, mildew, and long-term material issues.

Plan fixtures before finishes

Vanities, toilets, tubs, showers, mirrors, lighting, and storage should be planned together so spacing and usability work before tile and finish decisions are locked.

Think about maintenance

Durable materials, accessible plumbing decisions, grout choices, and fixture quality all affect how the bathroom holds up over time.
