Rated 5 out of 5 by from Outstanding features and quality We use our tub every week. Very relaxing and dependable

Rated 5 out of 5 by from Couldn't be happier with our hot tub!!! My husband and I had always wanted to get a hot tub and we were so impressed by the knowledge and service that we received. This is no ordinary tub...it is therapudic. My hubby has a bad back and I have a really bad shoulder and I can honestly say this has helped both of us immensely.

Rated 5 out of 5 by from Loving our new tub We’ve had our tub for about 6 weeks and use it twice almost everyday. It’s been easy to maintain and we love the relaxation it brings to our lives.

Rated 5 out of 5 by from Best Tub of the 5 I’ve bought As always Chris takes care of us. I’ve bought 5 tubs from Aqua Spas and if I need another there’s no question where I will go.

Rated 3 out of 5 by from Comfortable hot tub and easy to operate Appears to be well insulated and nicely finished exterior with durable but thin plastic. The hot tub only has one pump and does not produce strong pressure through the jets for this size or type of hot tub. This is our 3rd hot tub and this one does produce the least pressure compare to the others for the price. At an already high price, you would need to pay more for the two pumps option.

Rated 5 out of 5 by from Love love love our new hot tub! We are first time hot tub owners and were hoping it would be as wonderful as everyone said they were. We are not disappointed!! We love the tub. It's the perfect size for the 2 of us and if we have another couple over, it fits the four of us fine as well. Our grandchildren love it and it's such fun to get in with them too.

we purchased a hl 7.5 one of the neck jets does not seem to be delivering the water as consistently as the other side. Almost like it has too much air. Is this something I should have the dealer look at?

Asked by: Elizabeth
Hi Elizabeth! If you believe there could be something wrong with your spa we always recommend reaching out to your dealer.

Our siding was recently ruined in a very bad wind storm (small holes on two sides, where the cover lift mechanism was screwed in). Do you sell replacement siding panels or have suggestions on how to repair holes? 

Asked by: Jonesbcommon
Hello! You can purchase replacement siding panels from your dealer.

where can I get a replacement wire to the controller. it was shewed by a rodent

Asked by: Tunde Solarin
Hello! Unfortunately we do not have just the wire since most of them are soldered to controller. You would have to get the entire topside and overlay to replace the original. You can either contact your dealer to get the parts or you can do a Master Spas parts search on the internet. The search will bring up multiple websites that are run by our dealers. You would be able to order the part from any of them. Thanks for asking!

Can the deluxe fusion air stereo be installed on the hl 7.5 after it leaves the factory

Hello we have just set up our tub it is a HL 7.5 series and I am curious does it have a circ pump? Also I can hear a very dull humming but a bubbling sound and it's continuously running so should it be doing that?

Asked by: Lisa32
Hi Lisa! We would need your spa's serial number in order to determine that. Please feel free to contact our customer support to find out. They would be happy to help you! E: customerservice@masterspas.com P: 1-800-860-7727

Where do I find a detail manual/installation guide and /specification sheets for an HL7 spa?  I need to know power requirements, maintenance details, control location etc.   The web only gives general specs. 

Asked by: Bryan26
Hi Bryan. All of our manuals can be found in their entirety on our website under the "Resources" tab. Here's the direct link to the 2017 Healthy Living manual for you. http://www.masterspas.com/documents/_manuals/2017/2017-healthy-living-owners-manual.pdf

How do we lower the temperature from 103 to 90? We keep resetting per manual instructions but the temperature never goes down crom 103.

Asked by: Rick1950
The control system will not allow the heater to actually heat the spa above the set temperature without an obvious failure being noticed. There are several safety features designed in the control system to ensure this does not occur. With that said, the likely cause of this heat creep situation is friction. Pumps are capable of heating the water by friction caused from the movement of water in the spa. What we can do is check on your filtration cycles. If the spa is set for continuous filtration, that would mean your pump 1 is running on low speed continuously for filtration of your spa. I recommend setting your filter cycles to 2 which means that your pump 1 will run on low speed for filtration for 2 hours twice a day.

We just purchased a HL725 Model, I can't find it on your website. Need to print a brochure to verify dimensions. Purchased at the Hot tub show at the Civic Center in Glens Falls, NY. They were out of the brochures for this model and said to go on your web

Asked by: Stephen 21
Hi Stephen, we don't make an HL 725. Are you sure you don't have a HL 7.5? If you are looking for the 7.5, here are the dimensions. 84”X84”X36 214X214X92
