Key Takeaways
Shopping for a hot tub can feel overwhelming once you start comparing brochures, because nearly every model claims to be the best. This hot tub buying guide is designed to cut through the marketing and focus on the features that actually change how much you enjoy, and how much you spend to own, a spa over the years. Instead of chasing the biggest numbers, the goal is to match a hot tub to how you and your family will really use it. Below, the Spas & More team breaks down what to weigh before you buy.
The single most useful question is simple: who is going to be in the tub, and what do they want from it? A couple looking for quiet evening soaks has very different needs than a family with kids or a household that entertains often. Your answer drives almost every other decision, from seating to jets to size. Keep that picture in mind as you read, and resist the urge to buy more spa than you’ll use.
Seating is about more than a headcount. Pay attention to the mix of seat types. A lounger lets you recline nearly full-length for a deep, relaxing soak and targeted back and leg jets, while bench seats keep everyone upright, seat more people, and make conversation easier. Loungers are wonderful for one dedicated user, but they take up real estate, so a six-person tub with a lounger may only comfortably seat five. Sit in floor models if you can. Seat depth, contour, and how the water hits your shoulders matter far more than the advertised capacity.
More jets is not automatically better. A tub advertising a huge jet count often splits one pump’s output across all of them, which can leave each jet feeling weak. What matters is quality and placement: are jets positioned to hit the neck, shoulders, lower back, and feet where you actually hold tension? Are there different jet types for broad, gentle massage versus focused pressure? A well-engineered spa with fewer, better-placed jets and adequate pump power will outperform a jet-count champion every time.
Measure your space before you fall in love with a model. Consider not just the footprint but clearance for the cover to open, room to step in and out safely, and access for future service. Bigger tubs hold more water, cost more to heat, and take longer to warm up. A right-sized spa that fits your deck or patio and your household will almost always beat an oversized one you heat mostly empty.
In East Tennessee’s mix of hot summers and genuinely cold winter nights, insulation directly affects your power bill. Full-foam insulation fills the cabinet cavity around the shell and plumbing, trapping heat and quieting the equipment, and many owners find it the most efficient in cold weather. Other approaches, such as partial foam or reflective barrier systems, can also perform well and sometimes make service access easier. Ask how a given spa holds temperature through a cold snap, and treat energy efficiency as a long-term cost, not a footnote.
The acrylic shell is the surface you touch and the part expected to last decades, so ask about the backing material and warranty behind it. A quality shell resists fading, staining, and blistering. The cabinet is the exterior skirt; modern synthetic cabinets resist rot, insects, and weather far better than older real-wood designs and rarely need staining. Since your spa will live outdoors through Tennessee weather, durable, low-maintenance materials pay off.
Pumps drive both the massage and the circulation that keeps water clean and heated. Look for enough pump power to run the jets you care about, and note whether the spa uses a separate low-energy circulation pump for daily filtering, which is quieter and cheaper to run than cycling the big jet pumps. Modern topside controls should be intuitive, and app or Wi-Fi control can be genuinely handy for warming the tub before you get home, though it is a convenience rather than a necessity.
How you keep water clean shapes your weekly routine. Traditional chlorine or bromine systems are inexpensive and effective but require regular testing and dosing. Saltwater systems generate sanitizer from a salt cell, which many owners find gentler on skin and eyes and less demanding day to day, though the cells are a periodic replacement cost. Some spas add ozone or UV systems to reduce the chemicals needed. There is no single right answer. Choose the system whose maintenance rhythm you’ll actually keep up with.
A cover is easy to overlook and expensive to ignore. It is your biggest defense against heat loss, so a dense, well-sealed, properly sloped cover directly lowers heating costs and keeps debris out. Check the foam density and the seal down the center fold, and consider a lifter to make daily use effortless. A cheap cover waterlogs and sags within a couple of seasons, so it is worth getting right up front.
Extras can enhance the experience when they match how you’ll relax. LED lighting sets the mood and improves nighttime safety. Built-in audio is popular for entertaining. Waterfalls, aromatherapy, and cup holders are pleasant touches. Prioritize the add-ons you’ll use regularly, and don’t let a long options list distract you from the core fundamentals of shell, jets, insulation, and support.
Even the perfect spa causes headaches if the logistics aren’t planned. Sort these out early:
Getting the pad and power ready ahead of time is a big part of why professional hot tub installation goes smoothly. A knowledgeable team can walk your property, flag access issues, and confirm the base and electrical are right the first time.
A hot tub is a long-term relationship, not a one-time purchase. Water chemistry questions, filter changes, cover replacement, and the occasional repair are all part of ownership. Buying from a local dealer that stocks parts, supports its warranties, and services its own hot tubs means you have someone to call when you need help, instead of shipping a part across the country. That ongoing support is often worth more than a slightly lower sticker price online.

Not necessarily. A tub with a huge jet count often splits one pump’s output across all of them, which can leave each jet feeling weak. Quality, placement, and adequate pump power matter far more than the number of jets.
Match the size to how you will really use it. Measure your space and allow clearance for the cover to open, safe entry and exit, and service access. Bigger tubs hold more water, cost more to heat, and take longer to warm up.
Insulation directly affects your power bill, especially through cold winter nights. Full-foam insulation traps heat and quiets the equipment, while other approaches can also perform well and sometimes ease service access, so treat efficiency as a long-term cost.
Confirm the delivery path from the street, prepare a level, load-rated base such as a reinforced pad or purpose-built spa pad, and have a licensed electrician install the dedicated circuit most full-size spas require.
