Most people buy a hot tub for one of three reasons. They want relief from pain, like back or joint pain.

They want to relax after a hard day. Or they want something the whole family can enjoy together.

Many buyers find it becomes part of their daily life fast. Couples use it as phone-free time together.

Families use it as a place to talk and unwind.

Yes. Book a showroom visit and see the models side by side.

Sit in them, check the seats and the jets, and ask our team anything. Most people learn more in one visit than from reading spec sheets.

Text us to book your visit.

The right size depends on how you will use it. A couple wanting a quiet soak needs something different from a family of four.

Most hot tubs seat 2 to 7 or more people.

Smaller tubs cost less to run and are easier to care for. Bigger tubs have more seats and jet options.

Come try different sizes in our Tacoma showroom to see what feels right.

It depends on how you plan to use your hot tub. Think about how many people will use it, any health concerns, and where it will go in your yard.

We have many models in our showroom, so you can compare them side by side. Most people know the right choice once they sit in a few.

Come in or text us to start the conversation.

Yes, there is a big difference. Big box stores usually have only one or two models and often just drop the hot tub at your curb.

Getting help later means calling an 800 number.

At Black Pine, we deliver and set up every hot tub in the right spot. We have sold and fixed hot tubs since 1981, and the same team that sells it also services it.

Hot tub prices vary a lot based on size and features. There is likely a model that fits your budget, and financing can make payments easier.

We sometimes have sale models too.

Text us and we will tell you what fits your budget right now.

A well-made hot tub usually lasts 15 to 20 years with good care. The outer shell lasts the longest.

Parts like pumps and heaters usually last 7 to 10 years and can be replaced.

The biggest thing that affects how long your hot tub lasts is clean water. Bad water chemistry wears out parts faster.

That is why we include a Frog @ease system, which keeps your water balanced automatically.

Running a hot tub costs less than most people think. Most hot tubs across the country cost about $1 a day to run.

In the Tacoma area, electricity is about 40% cheaper than the national average. So local owners often pay even less.

A good cover also helps, since most heat is lost through the top. We look at insulation on every model we recommend.

Taking care of a hot tub is easier than people expect, and easier than a pool. Modern hot tubs clean themselves partly using ozone, a gas that fights bacteria.

We also add a Frog @ease system that handles chlorine for you.

Your job is simple: test the water once or twice a week, add chemicals if needed, and clean the filters on a schedule.

Most people use chlorine. The biggest mistake is adding too much.

Start with the smallest amount and adjust from there.

It is simpler than most first-time owners expect. You just test your water once or twice a week, add chemicals as needed, and clean the filters on a schedule.

Our Frog @ease system handles most of the daily chemical work for you.

We also email your owner's manual before delivery, so you know what to expect. And you can text us anytime with questions.

Chlorine and bromine are both good at cleaning hot tub water. We recommend chlorine.

Too much bromine can wear out soft parts like headrests faster than chlorine does.

Our Frog @ease system handles chlorine dosing for you automatically. You still check your water regularly, but it takes most of the guesswork out.

No, salt water systems still use chlorine. They just make chlorine using salt and electricity, so the result in your water is the same as adding chlorine directly.

The smell people dislike comes from too much chlorine, not chlorine itself. Salt systems do not fix that, and they can add more wear and extra steps.

How warranty repairs go depends mostly on your dealer, not the maker of the hot tub. Many dealers send out a repair person you have never met.

At Black Pine, we have run our own repair team since 1981. The same people who sell you the hot tub will also fix it.

Before delivery, think about three things: space, surface, and power.

  • Space: Leave 12 to 24 inches around the hot tub for access to the equipment. Make sure it can be carried to the spot.
  • Surface: You need a solid, level base, like a 4-inch concrete pad or a strong deck. Grass or dirt will not work.
  • Electrical: Some smaller models plug into a regular outlet. Most need a 240V circuit from a licensed electrician.

Check with your city or county about permits early on.

Setup usually takes a few hours once your spot is ready. The hot tub is delivered, placed in position (sometimes with a crane for tight spots), and hooked up to power.

By the end of the day, it is filling with water and heating up.

You can usually use it 24 to 48 hours later, once it reaches the right temperature. We walk you through getting the water ready before delivery day.

Yes, an indoor hot tub can work great, often in a garage or sunroom. Four things to plan for:

  • Access: Make sure doorways and hallways are wide enough to fit it through.
  • Structure: The floor needs to be strong enough to hold the weight, especially upstairs.
  • Ventilation: Hot tubs make heat and steam, so the room needs good airflow and moisture-resistant walls.
  • Drainage: Plan for splashes and for draining the water later. A floor drain helps a lot.

We recommend working with a licensed contractor for indoor setups.

Fair questions, straight answers

The worries we hear most, answered with facts you can check.

  • Aren't hot tubs full of germs?

    Not when the water is cared for.

    The CDC says keep chlorine at 3 ppm or more (or bromine at 4 to 8 ppm) and pH at 7.0 to 7.8.

    Shower before you get in. A clean tub smells like almost nothing. A strong chemical smell means something needs fixing.

  • Can I use a hot tub while pregnant?

    Talk to your doctor first. That is the CDC's advice.

    Keep the water at 104°F or cooler. The CDC also says children under 5 should not use hot tubs.

  • Will it really help me sleep?

    A big 2019 review found a warm soak 1 to 2 hours before bed helped people fall asleep faster and sleep better.

    That study looked at warm baths and showers. A hot tub warms you the same way.

  • Do I need an electrician?

    Yes, for most full-size hot tubs. A Platinum Refresh needs its own 50 amp, 220V circuit.

    In Tacoma, the electrical permit comes from Tacoma Power. We can tell you what your model needs.

  • Won't it cost a fortune to run?

    Washington power is cheaper than most of the U.S.: 14.71¢ per kWh here vs 18.31¢ nationally (July 2026).

    A thick, dry cover is the biggest saver.
