This hot tub buying guide gives you a simple order of decisions: who will use the tub and how, the seat layout, the footprint, 120V or 240V power, the site, jets, insulation, water care, the full budget, and delivery access. Settle them in order and the right spa usually becomes clear. Below are the steps, a checklist of questions to ask, and a table of real models from our listings.
Hot tub buying guide: how to choose a hot tub in 10 steps
1. Decide who will use it and how
A nightly solo soak, a couple unwinding after work, and a family that hosts on weekends need very different tubs. Hot Spring Spas puts usage first in its guide to choosing a hot tub, and its five buyer questions tie the model, size and accessories to your goals: family time, solo soaking, therapy or entertaining.
2. Pick seats and layout, including loungers
Seat counts are manufacturer numbers, and layout changes real capacity. A full lounger is great for one person stretching out but uses more room than a single bench seat. Bench and corner seats fit more people. Captain’s chairs and deep seats sit you lower so your shoulders stay under water.
3. Check size and footprint
Compare outer dimensions, not seat count. In our listings, a 1-person lounger tub is 34 by 78 inches, while a 9-person tub is 118 by 90 inches. Leave room around the tub for the cover lift, steps and service panels. Our hot tub sizes guide covers dimensions by seat count in detail.
4. Choose 110V plug and play or 240V
Plug and play tubs run on a standard 120V, 15 amp outlet, which saves the cost of a new circuit. The tradeoff is a smaller heater: the plug and play models in our table list 1.5 kW, against 5.5 kW on the 240V Canadian Spa models, so ask whether the heater and jets can run at the same time on 120V. Larger tubs with multiple big pumps need a dedicated 240V circuit, often 50 or 60 amps. A licensed electrician and your local code have the final word on wiring, GFCI protection and disconnects. See 110V vs 240V hot tub for the full comparison.
5. Plan the site and foundation
A filled hot tub is heavy. The Canadian Spa Burnaby lists 3,230 lbs filled before anyone gets in, and the 9-person Grand Bend lists 5,800 lbs. You need a flat, level base rated for that load: usually a concrete pad, a spa pad system, or a deck an engineer or contractor has confirmed. Our hot tub foundation guide compares the options.
6. Look at jets and pumps, not just jet count
More jets do not automatically mean a better massage. Look at pump horsepower, whether jets are adjustable, and whether each seat targets the area you care about (neck, back, feet). Brands describe hydrotherapy benefits; treat those as manufacturer claims.
7. Compare insulation and the cover
If you live somewhere cold, insulation and the cover matter as much as the jets. Look for full foam or layered insulation, an insulated floor and a thick tapered cover. Hot Spring notes that cold climates take more energy to keep water hot, so efficiency features pay off over time.
8. Choose a water care system
Most tubs in our listings include an ozone generator plus filters, which the makers say reduces chemical use. Some Canadian Spa models are listed as UV ready, with the bulb sold separately. Salt systems are another route. You still test water and buy chemicals and filters either way.
9. Budget for the whole picture
Hot Spring cites hot tub prices from about $4,000 to upward of $20,000 and notes that a value-priced tub may cost more to operate each month. Add electrical work, the pad, steps, chemicals, filters and power. Our hot tub cost guide breaks down price tiers and installation costs.
10. Confirm delivery access
Measure every gate, path and turn between the street and your site, and compare those numbers with the tub’s outer dimensions. Ask how the tub will be oriented in transit. Canadian Spa listings include curbside delivery, which means you arrange moving the tub to its final spot. Stairs or tight gates may mean a crane or professional mover.
Questions to ask before buying a hot tub
- How many people will use it on a typical night, and does anyone want a lounger?
- What are the outer dimensions, dry weight and filled weight?
- What voltage and amperage does it need, and can the heater and pumps run together?
- Is my chosen spot level and rated for the filled weight plus people?
- How many pumps, what horsepower, and are the jets adjustable?
- What insulation and cover come with it, and is it suited to my winters?
- What water care system is included, and which parts are sold separately?
- What is the warranty on the shell, parts, labor and cabinet?
- What delivery service is included, and how will the tub reach the site?
- What will electricity, chemicals and filters cost per month in my area?

The two plug and play Canadian Spa models list a 1.5 kW heater and a 2 HP two-speed pump, which suits small groups and patios. The Burnaby and Grand Bend list a 5.5 kW heater and multiple 5 HP pumps, which is why they need a 240V circuit. The American Spas listing shows conflicting pump details between its highlights and spec table, so confirm pump configuration with us before you order.

Safety before your first soak
A long-standing U.S. Consumer Product Safety Commission release says hot tub water should never exceed 104 degrees Fahrenheit, advises pregnant women to stay at 100 degrees or below, and recommends that people with heart disease, circulatory problems, diabetes or blood pressure problems get a doctor’s advice first. It also suggests special caution with young children and warns that alcohol raises drowning risk. Keep the locking cover on when the tub is not in use, and talk to your doctor if you have any health questions.
Frequently asked questions
How do I choose a hot tub size?
Count regular users, decide whether you want a lounger, then match the outer dimensions to your measured space with room for the cover and steps.
Is a plug and play hot tub worth it?
For one to four people in a mild climate, a 120V plug and play tub can save the cost of a new circuit. In cold weather or for larger groups, a 240V tub makes more sense; the 240V models we list carry much larger heaters.
What questions should I ask before buying a hot tub?
Ask about filled weight, power needs, pumps, insulation, the cover, water care, warranty and delivery. The checklist above covers each one.
How much should I budget beyond the tub price?
Plan for electrical work if you choose 240V, a level pad, steps, chemicals, filters and monthly electricity.
