Your spa needs a solid, level surface that can handle significant weight. A filled hot tub typically weighs between 3,000 and 6,000 pounds depending on size. Poured concrete pads (at least 4 inches thick) are the most common choice. Reinforced decking built to handle the load works well too, as do compacted gravel beds with proper drainage. The surface must be level within 1/4 inch across the entire footprint. Uneven surfaces can cause stress on the cabinet and shell over time. Before you commit to a foundation type, check with your dealer; they know the specific requirements for your model and can connect you with local contractors who've done this before.

Jets: The number, type, and placement of jets matter more than the total count. Directional jets target specific muscle groups; rotary jets provide a broader massage. Look for adjustable jets so each person can customize the pressure. Pumps: More pumps generally means more jets running simultaneously at full power. A spa with two pumps can deliver a noticeably more powerful experience than one with a single pump. Filtration: Clean water depends on good filtration. Sundance® spas use a multi-stage filtration system that keeps water cleaner with less chemical maintenance. Controls: Intuitive topside controls let you adjust temperature, jets, and lighting easily. Many models also connect to a smartphone app for remote monitoring. Lighting: LED lighting, including underwater and perimeter lights, extends evening use and sets the mood. Insulation: Full-foam insulation retains heat more efficiently, which affects your monthly energy costs. Cover: A well-fitting insulated cover is essential. It retains heat, keeps debris out, and is a safety requirement if children are around.

Not always. Seating capacity is based on the number of molded seat positions in the shell, but real-world comfort depends on a few factors. First, body size: larger adults need more legroom, and some seats are designed for average or smaller builds. Second, seat type: a lounge seat occupies footwell space that other seated users share when the lounge is occupied, it can effectively reduce the usable space for everyone else. Third, jet positioning: some seats are designed with specific jet configurations for individual use. A practical rule of thumb: subtract one from the stated capacity to get the number of adults who can soak comfortably at the same time. When you visit a dealer showroom, sit in the actual model you're considering. Wet test sessions are available at many Sundance® dealers so you can evaluate fit and comfort before you commit.
