Swimming Pool Construction
We design and build custom in-ground swimming pools tailored to your property's unique dimensions and your lifestyle needs. Our process begins with personalized consultations to understand your vision, followed by digital design creation and precise field layout. Utilizing experienced crews and quality materials, we ensure proper construction through each phase including structural integrity checks and city inspections. Our owner-managed approach guarantees consistent oversight from start to finish.
Pool Remodeling
Our pool remodeling service revitalizes aging pools built between the 1950s-1990s with modern designs and efficient equipment. We address structural updates while incorporating aesthetic enhancements like new tiling, water features, and integrated spas. The process maintains your existing pool footprint while improving functionality, safety, and visual appeal. Our team handles complete facelifts that increase property value and extend pool usability throughout the year.
Elevated Pools
We pioneered elevated pool designs that optimize small backyard spaces while enhancing safety and usability. These raised structures provide additional seating areas, reduce debris accumulation, and create striking visual focal points. Our engineering ensures proper structural support while integrating seamless transitions between pool levels. This innovative approach addresses modern homeowners' needs for multifunctional outdoor living areas within limited spaces.
Spa Installation
Our spa installations create year-round relaxation centers that complement your existing pool or stand alone. We design integrated systems with energy-efficient equipment and customizable features like hydrotherapy jets and LED lighting. The installation process considers optimal placement for temperature control and aesthetic harmony with surrounding landscapes. Our solutions prioritize ease of maintenance and long-term durability.
Outdoor Lighting
We install low-voltage lighting systems that enhance nighttime usability and security of outdoor spaces. Our designs highlight architectural features, create ambiance, and ensure safe navigation around pools and patios. The systems use energy-efficient LED technology with customizable control options. Proper placement and shielding prevent light pollution while maintaining functional illumination for evening enjoyment.

We are giving John Zahn (JZ) and the Sunset Designers & Builders team a rating of 5 only because 6 is not available. We have had many contractors and tradespeople work on our properties over the years, and Sunset was by far the easiest to work with while providing a superior result. Our project was to update an existing 25 year old pool/Jacuzzi and backyard deck/patio area. Our first meeting with JZ resulted in excellent design recommendations with a comprehensive written bid and schedule within a few days. After working out a few details and signing the contract, JZ started on time and finished

Sunset Designers and Builders are truly exceptional in every sense of the word. They took our blank-slate of a back yard and turned our vision into reality. John, Nate, and the whole team were highly communicative, transparent, professional, timely, and just good people. Contractors like this are one in a million.

John JZ Zahn was attentive, professional, and detail-oriented from the day he stepped into our yard. In 4 short months from the day we first met JZ, our pool and spa was ready for our now Kindergartener to splash around in the last
