What to Know Before You Buy a Hot Tub

Seats and size

Start with how many people will actually use the tub on a normal night, not the biggest crowd you can imagine. Most households are happy with a 4 to 6 seat tub.

Bigger tubs hold more water and take longer to heat and more power to run. A smaller tub that fits your real household can be the smarter buy, and it also leaves more room on a deck or patio for everything else.

If you entertain often, a few extra seats can be worth the trade-off. If it is mostly just you and your family, sizing down usually saves money on both the purchase and the running cost.

110V plug-and-play or 240V

Some hot tubs run on a standard 110V household outlet. These plug-and-play models are simpler to set up and do not need an electrician, which can make them a faster path from delivery to first soak.

Larger, more powerful tubs run on a dedicated 240V circuit, similar to an electric dryer. That means hiring a licensed electrician to run a new circuit to the pad, which adds a step and a cost before the tub can be used.

Ask which power type a model needs before you fall in love with it. It changes your setup cost and timeline, and it is much easier to plan for up front than to discover after delivery.

Site, pad and the path to get it there

The tub needs a flat, solid pad, usually concrete, pavers or a reinforced deck rated for the full weight of water, shell and bathers. A full tub is heavy, so the pad underneath matters as much as the tub itself.

Just as important is the path from the street or driveway to that pad. Measure gates, fence openings and tight corners before you order, so delivery day has no surprises.

If your yard has a narrow side gate or a steep slope, mention it before delivery is scheduled. It is far easier to plan around a tight path in advance than to work it out with the tub already on site.

• Confirm the pad is flat and rated for the tub's full weight
• Measure every gate and tight corner on the delivery path
• Know your power type, 110V or 240V, before you order
• Ask about permits for your city
• Plan where the cover will open and close

Electrical, permits and running cost

A 240V hot tub is an electrical job, and most cities require a permit for that work. In Tacoma, Tacoma Public Utilities handles electrical permits. Wherever you live, check with your city before work starts.

Running cost mainly comes down to your local power rate, how often you use the tub, and how well the cover seals in heat. A tub left uncovered or with a worn cover will cost more to run.

A well-insulated tub with a good cover and a reasonable set temperature is usually the cheapest to run day to day. Ask about the insulation and cover quality on any model you are considering.

Water care, cover and warranty questions to ask

Ask what water care system the tub uses and how often it needs attention. Some systems need less day-to-day chemical handling than others, which matters if you want a lower-maintenance routine.

Ask what the cover is made of and how it is expected to hold up over time. A good cover protects your investment and keeps the water clean between uses, and a weak cover means more work and higher bills later.

Before you buy, ask what the warranty actually covers, for how long, and what voids it. Get the answer in writing, not just a verbal promise, so there is no confusion if you ever need to use it.

Why visiting a showroom still matters

Photos and spec sheets only tell you so much. Sitting in a few models side by side shows you real differences in seat depth, jet placement and how roomy a tub actually feels.

A showroom visit also gives you a chance to ask every question above in person and get a straight answer before you commit, and to compare brands next to each other instead of from memory.

Bring your measurements and your short list of questions with you. That is the fastest way to leave a showroom visit with a clear answer instead of more questions.

Our showroom in Tacoma carries Platinum Spas, Vita Spas and Bellagio Spas side by side, so you can compare brands in one visit instead of driving all over town.
