Rated 5 out of 5 by from The Cadillac of hot tubs We love our new tub and use it daily. The water pressure is excellent for soothing those sore muscles. This tub also has great features such as mood lighting and waterfall to enhance the experience.

Rated 5 out of 5 by from Absolute Luxury and Quality! We LOVE our LSX 800! We have a family of 8 and we all love our new Master Spa LSX 800. The spa gets used every day and the water is always crystal clear. This is the 3rd hot tub we have owned and by far the best! The Afterglow lighting and the sound system really add to the luxury. The jets are great and very relaxing after a stressful day at work. We worked with the team at the factory and love that the spa is made in Fort Wayne IN which is about 30 minutes from our home. All the employees were great from sales to service and delivery/installation. A special thank you to our to our salesman Jim Bulger, Jim was fun to work with and very knowledgeable. He got us a great deal too! Also Doug, Shane, and Ryan were top notch to deal with. You can not beat the customer service from this team. Thank you to everyone at Master Spa-you all rock!! awesome!

Rated 5 out of 5 by from Love my master Spa LSX 800! Absolutely love my master Spa LSX 800. The Jets are amazing. They're so strong and are good at working sore muscles. My favorite spot is not what I expected. It's the simple seat between the two corners seeds. Never expected it but the Jets are so incredibly strong. I end up spending most of my time in that seat with the foot Jets right across from It On My Feet. I also sit sideways in the seat to get my legs because the Jets are the strongest in that seat for some reason. Even though I'm short and can't sit in the lounger, I love the lounger because I sit cross ways. It gets me out of the water to cool off but keeps the back of my knees right in front of the foot Jets. It really works the back of your legs well. The lounge jet works great for my husband who's taller. I can sit in that backwards in the lounger and get my legs that way. My back resting against the filter. The sound system is incredible. It is so loud you can easily hear it over the sounds of the motor and the pumps. We bought a $30 screen on Amazon and built a frame so we could watch outdoor movies in the hot tub. I have the Motorola phone that has the mod that has a projector. The whole setup is really cool. Even though it's 112 outside right now, we just turn the temperature down and we can still sit in the hot tub every night. We did have to change the water out in order to get the temperature low. Once it heats up hotter it won't go down. The filter like they say can be a problem. That's because it's got a great filter. They told us to take a hose with a high-pressure nozzle and just rinse it off every week. We've never had a problem since we started doing that. Awesome hot tub!

Rated 5 out of 5 by from Great family investment I am the very proud owner of a Master Spas MPL 800 series spa, my family just loves it in fact it has change our entire way of life for relaxing and enjoying life. I am new to the spa world, for the last 25 years we have always had above ground pools for the 6 kids, this year the kids voted and the pool was gone and replaced with a fire pit (the pool needed to be replaced this year anyway as the sides were rusting out). My wife and I saw an ad for a hot tube/spa show by East Coast Spas at the Oakdale theater in Wallingford CT and decided to take a look, the folks working the floor were fantastic and were able to answer every question we had (and there were many) there were no high pressure salesman, we took our time and we made the purchase. The unit was delivered by the very professional team from CR Spa service from Wallingford CT, the unit had to be placed in a building that we had constructed on our 4’ raised deck that was once the surround for the pool, they had the unit in place in about 30 min and then spent some time with us going over start up and operation. The electric service was connected that afternoon and filled, by the following day the family started the enjoyment of the hot tube. We did have a minor issue with the unit that is not any fault of the spa manufacturing or the delivery, one of the four pumps that started acting strange after several hours of use, we notified CR Spa services and they were right out and replaced the parts that were creating the issue, at no time did we stop enjoying the use of the hot tube. I went on line to East Coast Spa to order some supplies for the tube and being a pool guy I ended up unknowingly ordering the wrong stuff, in less than an hour I received a call from East Coast Spas customer service to review my order as they felt I may have made an error, they explained what I really needed , corrected the order and saved me a lot of money from the mistake I made. Now we have a great hot tube an enlarged deck a fire pit and all 6 adult kids are happy with the new “party” atmosphere, my wife loves the hot tube and the fact that the family is all together and having fun. I feel this has been a great investment for the family and look forward to many years of use. I would highly recommended Master Spas, East Coast Spas and CR Spa service.

Rated 3 out of 5 by from Nice but… Overall it is a decent Hot Tub but do NOT get the QuietFlo circulation pump. The pump is so loud I can clearly hear it from over 75 feet away (exceeds 55db). A Master Spas customer service representative said this was normal. Super disappointed because it is not quiet and can not be turned off. Calling this pump quiet is misleading an not something I expected from a premium brand.

Rated 5 out of 5 by from Perfect for a cold night. This hot tub is amazing! The jets are very powerful and it stays hot! I’ve had it for a couple months and haven’t noticed a huge increase in my electric bill.

Rated 5 out of 5 by from Good spa The spa itself is great, the only downside is the lounger. Hard to lay in it without floating away. Have to hang on and dig in.

I have a LSX 800. My pump 2 (lounger) will shut off after ~20 mins. I can press The jets button and it will light up (to indicate the pump is on) but no water comes out and I cannot hear the pump. Will work again after an hour or so.   Is pump defective?

Asked by: CHD2016
Hello Based on your information, your pump is overheating and shutting down. The pump won't turn on until it's cooled down. We recommend that you contact the dealer where the spa was purchased. If you need assistance contacting the dealer, please email us at with your spa serial number.

I bought an LSX 800 and wanted to know how thick the concrete slab to support it should be and how deep in the ground. Where do I put the power in and where is the front of the tub facing. (questions my contractor has). Thanks.

Asked by: Slamphilos
I would be glad to assist you. Foundation The recommended foundation is a concrete pad with a minimum thickness of four inches with steel reinforcement bars crossed throughout the pad.

We have one of your spas but we are now moving and leaving it for the new owner. We are moving to Idaho where the weather is cooler and wondering if we can inset the spa into the ground leaving room to get to the panel?

Asked by: Leslie
Yes, the spa can go in ground with a recommended 3ft radius around the spa for equipment access. You can read more under the "Site Preparation / General Guidelines" section of the owner's manual. Hope this helps!
