Rated 5 out of 5 by from Excellent quality tub We had an Arctic Spa for over 11 years and had several problems including the shell blistering. Arctic was great to work with except our local dealer is no longer a dealer for Arctic. The closest dealer at this time is in Pennsylvania and we are in North Carolina. So when it came time to replace our spa with something new we did our research and decided on Master Spas. Great features and great quality. It met all of our criteria. The dealer is a couple of hours away but are very responsive and easy to work with. We love our new spa, it is a great addition to our back yard. I would hghly recommend them to anyone looking for a quality built spa.

Rated 5 out of 5 by from There's a seat for whatever ails you! Owning a hot tub has been on my bucket list for a very long time. After reviewing many different brands and models, I wet tested the LSX 800 and decided on purchasing it. To me, the jets seemed strategically placed to hit target areas, which suffering from lots of aches and pains was important to me. My favorite seat is the Xtreme Therapy Seat with the adjacent Master Blaster foot jet. After a long shift on my feet, bending and reaching, it feels amazing! And, if the tendonitis in my arm is acting up, I can adjust the flow to the side jets to provided targeted therapy to my arms as well. For lower back pain, the seat between the Xtreme Therapy Seat and the Stress Relief Neck and Should Seat is the best! The jets are very powerful and just blast away at your sore muscles. If your neck and shoulders are the culprit, the Stress Relief Neck and Shoulder Seat is great, if you don't mind getting your face wet. The jets are powerful and sit above the water level, which causes quite a bit of spray.. Also be mindful that these jets are exposed to any chemical vapors rising from the water, so they need regular care to keep them from deteriorating. As a woman, I find the lounge seat very difficult to sit in...I just float away. The spa is a great size and allows for many people to share the experience at the same time, which is awesome for get togethers and parties! If you like to entertain, this is a great tub and I don't regret not getting the larger LSX 900. We have only had one issue with the tub, a bad pump, and that was promptly replaced under warranty by the local service company without any hassle at all! Having worked in retail in the past, I am understanding of the fact that quality control measures can't catch everything. The tub has been wonderful ever since!

Rated 2 out of 5 by from Love It but Not Meant for Shorter People We enjoy our hot tub but do not feel we bought the right fit for us. it is not the best fit for shorter people. I am 5'2" and can only comfortably use one seat. In the others, I can not reach the foot piece to stop from floating out of the seat. My husband is 5'6" and the recliner is worthless for both of us. Also, we bought a larger spa, telling the sales person, that we wanted it for entertaining friends and family, only two seats can have the jets blowing at a time. The others turn off simultaneously. This was a disappointment, that we did not expect. Over all, I wish the sales person would have provided us with more information so we bought the spa that was better suited for our needs.

Rated 2 out of 5 by from LSX 800 - most disappointing tub out of 3 hot tubs Incredibly disappointed with the LSX 800 for one key area. Need to hear if others are experiencing the same problem. The diverter, nearest the lounger, creates an incredibly loud disruptive noise continuously, when the diverter is moved towards the lounger. It is so loud and disruptive, we leave the diverter to push water/air through the feet jets which means the lounger is useless with no jet power. SErvice rep came out and said there is nothing that can be done.

Rated 4 out of 5 by from Good Tub if you are 6' tall The tub seems to be well built, aside from the exterior cabinet which lags behind other companies. You definitely get a far amount for your money. I enjoying get tub so far with only a few negative points. If you are shorter than 6' the lounger portion of the tub is completely useless. I would opt for the 700 series model instead of this one. Sales person did not point that out to me and it was my mistake that I didn't wet test the tub. The speaker system isn't very good either. Just save some money and buy a waterproof bluetooth speaker.

Rated 4 out of 5 by from Love my backyard vacation After searching and searching for the right hot tub my dad found this one in south Florida me living 4 hours away and no time to go check it out in person took his word for it ( dads know best right) when it arrived it looked huge which was great the light show it has is awesome still trying to figure out the jets and all the functions but I enjoy a nice quick get away after a long stressful day.

Rated 5 out of 5 by from Relaxing and Enjoyable! We use the tub very frequently. The control panel is easy to use, the diverter controls move smoothly even with the pumps running, led lighting is just the right amount (we actually like the slow transition through the colors). The corner seat with neck jets "splash"/"spray" .. water in my ear and on my face. Still experimenting with this feature but mostly just turn those off. The foot massage jets are awesome (very powerful). The lounge seat is also very nice. We have avoided those in the previous tub but it is very pleasant.

Rated 5 out of 5 by from We Couldn't Ask for Better! As a hard-working roofing contractor, my husband has many aches and pains at the end of the day. This hot tub takes them away in a matter of minutes! The adjustable jets give a gentle to rigorous massage, and the variety of the jets satisfies any muscle group. My own favorite is the seat with the lower lumbar jets, directly across from the master blasters for the feet, and right between two of the sound system speakers...simply bliss! (Easy to maintain, too!)

Can you use a couple trek planks and form pads to help level the 1" slope I have on one side of the spa on pavers?

Asked by: Frank
Hi Frank! In any instance of leveling the spa, you will need to make sure that whatever material that you are using can handle the weight of the spa when filled with water and you will need to make sure that the entire base is level so as not to add extra stress to the acrylic shell. Lastly, you will need to make sure that the footwell has support all the way underneath it. Hope this helps!
