OSLO | Frame Series
A square rigid-framed spa for six with wood-look panels that read like a built-in tub, and both an air bubble system and adjustable hydro jets. It assembles in minutes and packs down — MSpa's portability in a body that doesn't look portable.
Two massage systems
- 140 air jets across the base. The Variable Speed Bubbles system surrounds everyone in the tub at once, rather than serving only the three or four people sitting in front of fixed jets.
- 4 sets of hydro jets with 8 adjustable nozzles, driven by an 1,100 W jet pump — the largest in MSpa's Frame range. Aim the nozzles where you want them.
Light up the night
An LED light strip runs around the base and translucent fabric panels let the pattern glow through the body of the spa. Colours change to suit the mood, controlled remotely.
Control from the water or your phone
A foldable OLED touchscreen sits at the rim, so you never have to climb out to change a setting. The MSpa Link 2.0 app does the same remotely — heating, filtration and sanitation, with schedules and auto-calculation that starts heating in time for when you want to get in, plus tips, notices and alarms.
Water care, two stages
A built-in UVC unit treats the circulating water with ultraviolet light, and an integrated 5.5 W ozone generator (30–50 mg/hr output) works alongside filtration as part of the overall water-care system — no added chemicals at either stage. The liner carries MSpa's M-SHIELD™ antibacterial finish, which helps inhibit bacterial growth on the fabric itself, tested by the ISO 22196:2011 method.
Built to hold heat
MSpa's Heat Tech PTC heater allocates power intelligently between heating and the jets, and an energy saving timer lets you run the spa on a schedule rather than continuously. A foldable ground mat is included.
Anti-icing
If the water falls below 33.8°F (1°C), the heater runs automatically until it reaches 37.4°F (3°C), protecting the circulation system, pump and pipes.
ETL approved — third-party safety certification from a Nationally Recognized Testing Laboratory.
Details


MSpa Link 2.0 App: Say goodbye to reaching over your spa — or worse, getting out of your soak — just to change a setting. Manage every aspect of your spa, from heating to cleaning to sanitizing, right from your phone. Set schedules that fit your lifestyle and let intelligent auto-calculation get your spa ready exactly when you want it. Receive tips, notices, and alarm messages on the go, so you're always in the loop.
OLED Touch Screen: All your spa controls in one convenient unit. The OSLO's sleek, foldable OLED touch screen lets you manage every spa feature from the comfort of the water.


LED Lighting — Light Up the Night: Take your spa experience to the next level with an LED light strip at the base that makes your spa glow. Translucent fabric elements let beautiful patterns shine through for a relaxing evening atmosphere. Switch colors based on your mood and enjoy late into the night.
UVC Sanitization System: The new MSpa collections include a built-in UVC unit that uses ultraviolet light as part of the spa's water care system — no added chemicals required for this stage of treatment.


Ozone Generator: MSpa hot tubs feature a built-in O3 ozone generator that works alongside filtration as part of the spa's overall water care system.
Hydromassage Jets Plus: Four sets of adjustable hydro jets deliver a targeted massage experience, letting you direct the flow where you want it for a relaxing soak.


Anti-Icing System: When water temperature drops below 1°C (33.8°F), the heater runs automatically until the water reaches 3°C (37.4°F), helping prevent freezing and protecting the circulation system, pump, and pipes.
Smart Filtration: For best water quality, clean the filter cartridge after each use and replace it as recommended. A reminder appears at least once a week while the spa is running, so you never have to track it yourself.


Antibacterial Liner Fabric: The inner liner is treated with an antibacterial finish that helps inhibit bacterial growth on the fabric itself, tested to ISO 22196-2011.
Variable Speed Bubbles: Our Air Jets Massage System creates thousands of bubbles from the base of the spa, surrounding you from all angles. Unlike hydromassage jets, which serve 3-4 people, the Air Jets Massage System can be enjoyed by everyone in the tub at once.
F R A M E S E R I E S
The FRAME series combines modern design with outstanding performance. Luxury wood-like finishes are applied to the spa body for rigidity, resembling traditional built-in hot tubs while keeping the portability you know and love from MSpa.

Setting it up
- Power: plug into a properly located outdoor receptacle on a GFCI-protected circuit rated at 30 mA or less, and test the GFCI before each use. Do not use an extension cord. Bonding requires a minimum 6 AWG solid copper conductor.
- Surface: flat, smooth and able to carry the load. Filled and occupied that's around 3,900 lb over roughly 35 square feet — about 110 lb per square foot. Do not place it on a deck, balcony or raised structure without having the structure assessed; an unsound or uneven surface voids the warranty.
- Not on grass or dirt — debris gets into the water. Clear sharp objects from under and around the spa first.
- Out of direct sunlight, to protect the shell and extend its life.
- Indoors: ventilate the room, or humidity will build up.
- Cold weather: do not install or operate in ambient temperatures below 39°F (4°C). Anti-icing protects the spa in standby; it isn't a licence to run it through a hard freeze.
Filter maintenance — plan for it
Clean the cartridge gently after every use and replace it every 3–5 days, or sooner if it stays soiled or discoloured. Two cartridges are included; budget for regular replacements. A reminder appears at least once a week while the spa is running.
Warranty
12 months on electrical parts and the spa pool.
Who it's for
People who want a square, solid-looking spa with both bubbles and directed hydro jets — no slab, no electrician, no permanent commitment — and who care what it looks like lit up after dark.
Before you use it
Never let the water exceed 104°F (40°C). Pregnant women should keep it to 100°F and sessions short — hot water immersion can harm a fetus. Do not use alcohol, drugs or medication before or during use; they can cause unconsciousness and drowning and increase the risk of hyperthermia. Consult a physician first if you are obese or have a history of heart disease, high or low blood pressure, circulatory problems or diabetes, or if you take medication. Do not use immediately after strenuous exercise. People with infectious illnesses should not use the spa. Children must be supervised at all times and prevented from reaching the spa unattended. Keep electrical appliances at least 5 feet from the water. Prolonged immersion may be injurious to your health.
