Rated 4 out of 5 by from Mostly Great Hot tub is great. The Ozone/UV isn't working upon delivery and took some troubleshooting to isolate the problem. Notified Leisuretime Warehouse about it and hopefully they help us resolve it quickly.

Rated 5 out of 5 by from The Best Investment We Made for Our Home We absolutely love our hot tub and honestly can’t imagine our backyard without it now. It has completely transformed our space into somewhere we actually want to spend time every day — whether it’s relaxing after a long day, enjoying quiet mornings, or entertaining friends and family on the weekends. From the quality of the tub itself to the overall experience with the company, everything has been amazing. The team was knowledgeable, professional, and made the entire process smooth from start to finish. You can truly tell they care about their customers and stand behind their product. Our hot tub has become a staple in our home and one of the best investments we’ve made for both relaxation and entertaining. It brought a whole new level of comfort and enjoyment to our backyard, and we constantly get compliments from guests. We couldn’t be happier and would highly recommend them to anyone considering adding a hot tub to their home!

Rated 5 out of 5 by from It's already helping my back 🥺 We love the look, ease of use, functionality, and most importantly the purpose of our Master Spa--to alleviate back pain for me. It's been so good to me and it's been less than a week 😇

Rated 5 out of 5 by from Love our new Master Spa hot tub! We love relaxing in our master spa 8.25 Hot tub. We use it approximately 3 to 5 times a week all year long. It is very relaxing to start the day out in the hot tub. We absolutely love master spa . This is our third one.

Rated 5 out of 5 by from Twilight is worth it! We use our tub almost every day. We are a month into owning it and very happy with the purchase. The quality is great and the warranty on the Twilight series made the purchase a no brainer. Our son comes back from college much more often to come soak in the tub.

Are there any slip resistant pads you can buy for the tub?

Asked by: Howie
The interior step in our TS 8.25 features a slip resistant pad - extras of this pad can be ordered and purchased from a dealer. The very base of the spa does feature a patterned surface to allow for additional grip.

Where does the electrical wiring need to emerge? From underneath the spa or can it come through the side?

Asked by: TJHe
You can go either route! If you’d like a flush conduit coming up from underneath the hot tub cabinet, we’ve included a helpful diagram in the Electrical Configuration section (https://www.masterspas.com/hot-tub-electrical-requirements/) of this website that shows the ideal entry point! This location avoids plumbing and gives you the smoothest path into the cabinet. If your pad is already poured or you prefer to bring the conduit in from the side, that works as well. You can enter from any side of the cabinet that best fits your setup. There’s enough clearance along the bottom perimeter of the spa to route your electrical supply. Once inside the cabinet, the wiring will need to be run internally to the spa pack. For the TS 8.25, the spa pack is located on the same side as the control dial, and when facing the controls, the electrical should enter from the left. Many customers find it easiest to come in through a corner for cleanest routing. Quick tip: electrical runs can get expensive the more wire your electrician needs to install. To help plan ahead, take a look at the Site Preparation section of your model’s owner’s manual (available on this website: https://www.masterspas.com/hot-tub-owners-manuals/ ) and share it with your electrician. It’ll make the setup easier and help ensure everything is prepared correctly!

I would like to purchase the same chemicals that came with my HT. It came with the master clear kit. Where can I find these chemicals?

Asked by: FrankC
The chemicals that came with your spa are a special gift from your individual dealer, they make starter kits with chemicals they themselves often sell directly either in a store or website. You should be able to locate your direct dealer's contact information for sales on your spa contract or receipt. You may also call us 800-860-7727 for help to locate your dealer's contact.

A spa tech told me to install a TS 8.25 on a 60A circuit and change a setting on the control board so that the heater won’t shut down when both pumps are on. Would this work?

Asked by: BAC1
Please Note - Altering your spa pack and or electrical supply will change the energy certified specifications of your spa to something alternate to what we as the manufacturer intend and may be an important factor to keep in mind if ever troubleshooting an issue. Although we cannot specifically advise doing so, many control systems do offer capability to change how many components can operate together. You can change dipswitches on a Balboa pack (which Twilights current and in the past use) to allow the heater to run at the same time as your as 1 or more of your two speed pumps in High Speed instead of Low Speed. One of the reasons your spa normally behaves to heat on low speed is avoid nuisance tripping - running each of pumps at aprox 12 amps (max speed, the heater at the same time at aprox 12 Amps (max heating) as well as accessories like LEDs, ozones etc. - can be too much draw and pop the safety braker making you reset the spa. This may be why your tech recommended the higher amp breaker of 60A instead of 50A so your spa has a higher supply to draw from. We recommend as always to have your spa hookup professionally handled by a certified electrician to make sure you are receiving a proper supply and updated gauge of wire. You can also try altering to allow 1 High Speed pump (as Twilight 8. 25 have 2) to run while maintaining your 50 amp normal hookup.

What make and model spa pack is in the TS 8.25? The online owner’s manual only has info about the topside control.

Asked by: BAC1
In order to answer this question it is best to call or email into our line directly - as models have changed over the years so have parts and their current year equivalents/replacements. Your spa serial number can be found on the minimum fill line sticker, your owner's manual and a metal plate near the pack itself. If you can gather this it will be the most accurate way a rep can tell you what is supposed to be contained inside. The pack will also have a label on the inside of the pack lid telling you what pack it is as well. 1-800-860-7727 or customerservice@masterspas.com.

Where do you order your replacement filters from?

Asked by: Annie64
Your dealership where you purchased the spa would be our first recommendation! However, there are dealer/retailers that function entirely online like www.MasterSpaParts.com, or www.MasterSpaPartsOnline.com where you can also purchase anything a dealer would sell right to your door. If you'd also like a list of available Master Spa retailers nearby you can always give us a call! 1-800-860-7727
