The illusion of choice.

The hot tub aisle looks like dozens of hot tub manufacturers. Trace the ownership and it’s a handful of companies, several of them selling against themselves under different names.

03What it costs you

What consolidation does to your hot tub.

When the good, better and best brands in a showroom share one owner, the showroom is a price ladder, not a competition. Here is where that shows up after you buy.

01

Different badge, same building

Several names on this map come off the same production floor.

Marquis and Artesian, sold for years as rivals, have been built in the same Las Vegas plant since 2023. Hot Spring and Caldera share a manufacturer and its two plants. When the brands in a showroom share a parent, choosing between them can be closer to choosing a price tier than choosing between competitors.

02

Parts you can only buy one place

Many brands build around their own controllers, jets and filters.

That is normal engineering, but it decides who can fix your tub in year eight and what the parts cost when they can. Standard parts give you options. Brand-only parts give you one.

03

Service that runs through one network

Warranty work usually has to go through the brand's authorized dealers.

When a parent consolidates or drops a brand, your support path moves with it. Two brands on this map are already sold through a sibling brand's website.

04

An owner with an exit plan

Private-equity funds usually buy a company intending to sell it again within several years.

Three of the owners on this map are private-equity firms. That does not make their tubs bad. It does mean the company honoring your ten-year warranty may not be the one that sold it to you.

05Latest

Hot tub news you might want to know.

Ownership and factories change quietly. When something moves, it goes here first, with what we know and what we don’t.

Developing

Arctic Spas auctions off 686 items from its Alberta plant

An unreserved online auction at Arctic Spas’ Thorsby, Alberta headquarters closed on September 22.

It included 38 finished hot tubs and swim spas, 167 spa parts, three robotic arms, shop tools, six trucks and two trailers. The listing gives no reason, and we found no public statement from the company as of September 23. The company’s website still lists Thorsby as its main plant. Factories clear surplus all the time, so an auction alone doesn’t mean trouble. We’ll update this when we know more.

Leadership

Master Spas gets a new CEO

Longtime CEO Terry Valmassoi retired on June 30 and stays on the board.

Kevin Richards is now CEO. The company remains privately held.

Plant closure

Jacuzzi to close a Georgia bathtub factory

A state filing shows Jacuzzi shutting its Valdosta, Georgia plant, with job cuts affecting more than 100 workers.

The plant builds bathtubs, not hot tubs, so Jacuzzi and Sundance spas are not directly affected.

Rebrand

Aqua Living stores become Whisper Outdoor

The Tennessee chain that sells LPI’s eight hot tub brands is renaming its stores Whisper Outdoor.

The company says the stores, factories and brands stay the same.

06Ask your dealer

Five questions. Watch how they answer.

  1. Who owns this brand, and has it changed hands in the last five years?
  2. Which factory builds this exact model?
  3. Are the pumps, heater and control pack standard parts, or only sold through your dealers?
  4. If this brand is sold or discontinued, who honors the warranty?
  5. Do you sell other brands from the same parent company, and how do they actually differ?

A good dealer answers all five without flinching. If they can’t, you’ve learned something.

How we built this

Every ownership fact on this page links to where it was published: company filings, official acquisition announcements, manufacturer websites and trade press. Where only one trade source supports a claim, we mark it “reported.” Where we could not verify something, we left it off. This page describes ownership, not the quality of any individual tub.

A “brand name” here is a name a company sells hot tubs or swim spas under, as listed by the owner or in its filings. Every one is on the map above, so you can recount them. Product lines inside one brand, like a manufacturer’s series names, are not counted separately. A solid line means a source puts the brand in the same factory as a sibling. A dashed line means we could not confirm that, not that the factories are proven separate.

Spot an ownership change we missed? Tell us.

Know who builds it? Now see what a good deal is.

Pick the model and how you’d like to hear back. We send you the price range, then introduce you to one dealer near you, and no other dealer unless you say so.
