Rated 5 out of 5 by from Nice Hot Tub - Built Like a Tank We haven't had a chance to use it as we are still waiting on electrical, but from my research and the my personal analysis, it seems well built. I's like to give Chris Wheatley from Hot Tub Universe a big thumbs up for his recommendation and fantastic customer service in helping us to decide on Master Spa. We purchased this unit directly from him, of course with the help of his staff Theresa and Scott.

Rated 5 out of 5 by from Very Satisfied After 10 years of saying we wanted a hot tub, we finally got one. We went to a hot tub blow out sale. I was skeptical of buying a floor model, but so far it has been great. The 3 person is perfect for me and my husband. The size also looks appropriate in our yard. The HL 628 has the perfect amount of jets. It is very relaxing. I have only used it twice because the weather has been too cold for me but my husband has been in it every night. Our only recommendation is to have better instructions for set up. We had an issue with the electrical and thought something was seriously wrong with the hot tub, but it was a simple fix of switching 2 wires which apparently happens often when installed.

Rated 5 out of 5 by from Love It Tub was delivered on October 27, 2018. Delivery was smooth, on time, and the guys were awesome. My wife and I love this spa. We bought it primarily for it's therapeutic value, and also to enjoy some R & R time together listening to music. This spa (220V) has one pump and more than enough power. So much so that we normally don't open the jets all the way. Really love that we can control every jet, as well as the amount of air bubbles. It's simple to operate and easy to maintain. We are very pleased with our choice. Only issue is that the nozzle for the water feature was pointing to the outside of the tub. Would shoot a small amount of water out of the tub when the jets were first turned on. New part was ordered and now awaiting appointment to correct the issue.

Rated 5 out of 5 by from Really rejuvenating! The hot tub makes for awesome water therapy. We really enjoy it. Glad there is a multi color light for the night time. The jets are great! I’m shorter than my husband 5’ 11”. And the recliner area for him is perfect at the water level. For me {5’ 2”} though it’s up my chin level. So for smaller bodies the recliner seat isn’t as comfortable as it should be. otherwise, it’s one of the best investments we’ve ever made.

Rated 5 out of 5 by from Hot tub is everything I expected After having an older small hot tub with 4 jets this one is great. It is a big step up. Jets are placed exactly where they should be and have plenty of pressure. Even though it isn't a large tub it feels large.

Rated 5 out of 5 by from First Hot Tub and excellent choice! After getting water chemistry perfect in 3 days we were relaxing on our hot tub. I can tell you that the insulation and cover hold in heat. We filled our tub with filtered water from garden hose. Primed the pumps and after first filter cycle the temp was a cold 80 degrees. Set heater for 80 degrees (so it would not come on). After one day in the sun with cover on...it was a boiling 105 degrees. We had to vent the cover to keep the water closer to the ambient temp of 95 outside (lessons learned). We love this tub and is perfect for only two people. Anymore people and water displaced by your bodies will overflow this tub. The three different seating and jetting differences give the best light/medium and full body massage by water ever! Work days go by faster....because we can’t wait to get home and relax in the tub!

Rated 5 out of 5 by from Great purchase We were hesitant to purchase a smaller spa but this has met every expectation we had and more! The jets are strong, plenty of room for two people and we use it every day. We couldn't be happier with this spa.

Rated 5 out of 5 by from We love our hit tub! My husband has chronic back pain, has poor circulation in his one good leg and is has already lost one leg. He refuses to take narcotics. He is getting relief in out hot tub 5 or 6 times a day. Absolutely the best purchase we've ever made. I look forward to getting into it as soon as I'm home from work.Absolutely the best purchase we've ever made

Our healthy living 628L has the water feature in the pocket on the top of the acrylic shell that pumps water up and over the outside of the tub when the jets start up. We have a constant puddle outside the tub as a result. What can we do about this?

Asked by: Candace99
Hi Candace. Have you made sure to open all the other jets to see if that helps? If you wouldn't mind taking a video of the flow of that water feature and emailing it to customerservice@masterspas.com we'd love to help figure this out for you. Thanks!

How much wood is in this hot tub? Where is the wood?

Asked by: SueA
Hi! The only wood that is used on the spa would be for the frame of the spa. The amount of wood that is used for the frame is based on the model and size of the tub, so a smaller spa = less wood. Hope this helps!

My hot tub will not heat. I am getting the message 5L in the window. How do I rectify this? What does the 5L mean. Thank you. Jim Hartman

Asked by: Nikki2012
Hi Jim! Are you sure it's not SL? SL means your spa is in 'sleep mode'. Just press your temperature button, and then the light button. Your spa should go back into standard mode after that. Thanks for asking!

How o I correctly set the temperature? It seems I cannot get the temp to hold at 102degrees

Asked by: larryhummel
Hi Larry! In order to set your temperature, you will have to press the warm or cool button on your topside control panel. The displayed temperature will change and begin blinking a new number. This blinking number is the set temperature. If you are noticing the temperature change when you are in the spa and the pumps on, this is because the spa is designed to run with 1 pump on high speed, so with both pumps running it will turn the heater off. This is to reduce stress on the GFCI breaker so that it does not cause tripping or any other issues. Hope this helps! Thanks for asking!
