A custom pool house is a standalone or attached structure built alongside a residential pool that extends the outdoor living and entertaining space. Most include covered seating, restroom facilities and storage. Higher-end pool houses may include full outdoor kitchens, changing areas and separate bathrooms. The Santa Barbara Estate pool house in Las Vegas includes a covered trellis with chamfered columns and wood beams, separate women’s and men’s outdoor bathrooms with dual sinks and hand-painted tile, custom Moroccan-style lighting and period-inspired doors with decorative clavos hardware.
