Why Buy A Dimension One Spa

Lifetime warranty on Dimension One Ultralife Shell

Dimension One Ultralife Shell

Acrylic shells are usually backed with fiberglass or ABS. Over time, the acrylic can separate from the backing material. This is called delamination, which causes blistering, peeling & cracking. Most hot tub manufacturers will give you a long warranty on the structure, which is the backing, but a fairly short warranty on the surface, which is the acrylic. So, your tub may not leak, but it will look pretty bad.

D1’s Ultralife shell is a patented material that is completely indestructible, and has a lifetime warranty.

90% less chemicals than other hot tubs

Ultra Pure Water Management

Our patented Ultra Pure Water Management System sanitizes and disinfects your spa water, which virtually eliminates your chemical requirement. The level of chlorine you need to maintain is equivalent to what is found in drinking water. Using the same technology that is found in water treament plants and amusement parks, your water passes thru multiple scrubbing chambers, where all of the living microorganisms are killed off naturally – no odors, no by-products!

D1 won the industry’s first-ever UL Listing for operating a purification system while people are using the hot tub!

Energy Efficient

Energy Efficient

  • Our spas only use $25
  • $30 Unlike most hot tubs that cost $80
  • $200 per month to operate, and that’s based on LIPA rates!! This is because of many factors:
  • all spas have full foam insulation, which locks in the heat
  • high density foam covers, which are custom made for each tub to fit tight around the edges
  • 85% of the heat generated by the pumps is returned to the water, so you’re getting free heat
  • filtration, heating and sanitation is driven by a low power, 98 watt circulation pump.
  • Our hot tubs are expertly engineered and plumbed so that the pumps are best utilized, ensuring that there is no wasted energy or horse power. This means a smaller more efficient pump that gives you more jet power than our competitors.

Engineered for Comfort


Dimension One has studied human anatomy, ergonomics, fluid mechanics, aquatic massage, acupressure, and reflexology so extensively they actually invented a new science; we call it “hydronomics.” Using state-of-the-art modeling software, D1 engineers design our hot tubs in virtual space, which ensures the ultimate in comfort.

The culmination of hydronomics can be experienced in our BioForm Seating features:

  • Non-float seating designs
  • Optimized body positioning
  • Full body immersion
  • Ideal jet and control placement
  • Correct size and type of jets

Right for Any Height

NeckFlex Jet Pillow

The NeckFlex Jet Pillow is a patented headrest with built-in neck and shoulder jets. It’s adjustable in 5 positions, so no matter how short or tall you are, you’ll get the perfect massage. D1 customers say this is their favorite feature of their tub!

The Ultimate Massage

Dynamic Massage Sequencer

Our Dynamic Massage Sequencer allows you to select from 6 different massages. Jets will automatically turn on and off, creating a ‘dynamic massage’. You can pause the sequence, to target specific areas, and control the speed of the sequence.

Special Effects

lighting effects

Our lights and water features are not just another me-too option. Instead of the normal, boring waterfall, we have babbling brooks and fountains that can be adjusted from a few inches high to many feet in the air. And our 28 color LED lights not only make your water glow, but our perimeter lighting will make your spa a part of your landscape.

Architectural trim


Our Oak & Cherry finishes look like real stained wood…without the maintenance. Or you can choose our beautiful cattail design, truly making your hot tub part of nature.

Kills Bacteria Naturally

Vision Cartridge

Our proprietary Vision Cartridge uses minerals that naturally kill bacteria on contact. It significantly reduces the need for chlorine or bromine.

Customer Testimonials
Rich & Pam C., Medford
“Your knowledge about Dimension One Spas and how they differ from other brands was incredible. You answered all of my questions (and I had a lot of them!), and understood what I was looking for in a hot tub. After all of my research, it’s easy to understand that all hot tubs are NOT created equal.”
Don O., Coram
“After falling off a ladder, I just returned to work on full duty. The hot tub has been a Godsend. When I was going to therapy I was sitting in the hot tub for 20 minutes prior, and the therapists all said that was probably the best thing I could have done, plus it made the injuries feel a lot better faster.”
Paula S., Farmingdale
“Since I purchased our Clearwater hot tub, I feel like I’m on vacation in my own backyard. Even in the cold weather, it’s a delight to step into pure bliss, an instant “ahhhhh” feeling and a total body water massage setting me up for a great night’s sleep.”
Paul & Margaret K., Seaford
“Price and energy efficiency were concerns to us. But that really is not a factor. My LIPA is only about $40 more a month!”

“Your friendly service and advice whenever I come in for supplies made this purchase one of the best investments I have ever made.”
Cindy R., Woodbury
“Surprising my husband with our Dimension One hot tub from The Hot Tub Factory for our 25th wedding anniversary was possibly the “best gift I could ever have received”, he said. It was an investment well worth it. We’ve had a lot of fun drinking wine late at night with nobody around and have had a blast with our friends on the coldest of days and the most beautiful summer nights.”
Rob & Lauren H., Islip
“We love the hot tub all year long. We are just beginning to invite friends over and I am sure in time we will be recommending a handful of new customers in your direction. We have also enjoyed The Hot Tub Factory before and after the purchase. This means a great deal to customers like us.”
Paul & Margaret K., Seaford
“The jets are perfectly placed to work each part of your body from head to toe. The pressure controls let you choose your best comfort zone. But really, the true test is after you have been in this spa you sleep like a baby! If you have a chill in your bones after being out in the cold NY air -get in your amore bay -your chill is gone!”
Eric & Fara M., Holbrook
“We were looking at the cheap tubs at Costco but heard many bad things about them; such as bad energy efficiency and subpar quality. I guess you get what you pay for! Spending the little extra on a quality D1 tub was worth every penny.”
Cindy R., Woodbury
“I found The Hot Tub Factory practically by accident and never regretted it. Norm and Mike are knowledgeable and well trained by the vendors they represent. I was taught all I needed to know and still, one year later, will call with questions when I’m not sure what to do. Susan is always patient with me. Get your own tub, the water is beautiful!”
John & Jennifer S., Patchogue
“We wanted to make sure we would get the best value for our money with the longest life span. We looked at hot tubs with TV’s, speakers, waterfalls, mermaids painted on the floor and every other thing you could imagine. We looked at every price range including internet based companies that were a quarter of the price of what we inevitably spent. After going to every hot tub store within fifty miles we decided on a Dimension One hot tub. Everything that was told to us was true!”
Larry S., Holbrook
“I use my Jacuzzi Hot Tub at least twice daily. I have severe leg and back issues and I receive some very real relief. If I use the tub before bed time, I can get a great night’s sleep.”
Paul & Margaret K., Seaford
We use our hot tub 3-4 times a week. We love the way it calms and de-stresses after a long day at work. We did our homework before choosing the Dimension One Amore Bay. We have and would recommend it to anyone looking for a spa that gives you instant relaxation.”
– Larry S., Holbrook
“In all, a very good investment and my wife enjoys the quiet time we spend together, late at night, under a clear, starry sky!”
John & Jennifer S., Patchogue
“We are really looking forward to the winter because we find we enjoy it most in the cold, especially in the snow. We have started a new tradition on New Years Day: we have no company, plenty of champagne, food and music and we spend the day in the bubbles.”
Eric & Fara M., Holbrook
We use our hot tub about 5 times per week. When I am in it, I feel like I am on vacation!! It is the best feeling to be in 104 degree water when it is 30 degrees outside. It is much cheaper than a pool, and you can use it year round; so it is a no-brainer to choose this over a pool. Perhaps in the future I can upgrade to a swim spa.”
Dennis F., Fire Island
“We’ve had the hot tub for several years now at our vacation house and it works perfectly, we use it several times a week in the summer and drain and winterize it during the off season when we’re not there. Great product!”
Christiane M., E. Northport
“Thank you for a great hot tub. We love it and use it 2 or 3 times a week, usually after work in the evening. Its great relaxing together and we have arranged it in our greenhouse where we can feel like we’re outside while protected and private. The maintenance is very easy.”
David P., Middle Island
“I go in it almost every night & it really makes my back muscles feel great. I had back surgery & I feel the hot tub really helped with my recovery. I also wanted to thank you guys again. I had an issue with my pump & when I contacted you guys someone was here the next day & resolved the issue.”
Rich & Pam C., Medford
“I just wanted to thank you for the fantastic experience during my Dimension One purchase. I am one of those people that do my due diligence when making an important purchase. In comparing my visits to many hot tub stores on Long Island, The Hot Tub Factory was, by far, the best!”
Kevin E., Roslyn
“Your product is great as was the price and the service. I strongly recommend The Hot Tub Factory.”
Paula S., Farmingdale
“Since I purchased our Clearwater hot tub, I feel like I’m on vacation in my own backyard. Even in the cold weather, it’s a delight to step into pure bliss, an instant “ahhhhh” feeling and a total body water massage setting me up for a great night’s sleep.”
John & Theresa D., Oakdale
“Norm & Mike…….sorry we would have emailed you sooner but we just got out of the tub. We are going in every night and we are staying in for hours and loving every minute!!!!!!!!!!”
