Excellent
LOVE this suana. Maya and Norse Steam Team were amazing to work with!
The MSpa Frame Series holds the Mono, Oslo and Denver, three round portable hot tubs that seat six people. Their panels with a wood-like grain lock together, giving you rigid walls while the tub still packs away. Choose the Mono for bubbles from air jets, or the Oslo and Denver for water jets too. Those two also come with screens and lights, while the Denver adds phone controls.
What makes the MSpa Frame Series different?
Wood grain plastic panels lock together around each tub, so it holds its shape like a built-in spa and still packs away, keeping the portability of the other MSpa hot tubs. Each six-seat portable hot tub plugs into a standard outdoor outlet. Compare them with inflatable hot tubs, or browse the full MSpa range.
Choose your Mono, Oslo or Denver
The Mono is 68 inches wide and 26 inches tall and holds 245 gallons. The Mono has 138 air jets and comes with an insulated cover, inflatable insert, hand pump, foam mat and filter cartridges. The Oslo is 70.9 inches wide and 26 inches tall and holds 304 gallons, the most of the three. The Oslo adds hydromassage jets and a touch screen, with a buckle cover, insert, LED light strip, ground mat and spare filter cartridge in the box. The Denver is 71.7 inches wide and 27.6 inches tall and holds 256 gallons. The Denver has water jets, a folding touch screen and an insulated cover with an insert, plus lights shining through translucent panels. The MSpa Link 2.0 app on the Denver lets you schedule heating, cleaning and sanitizing from your phone. If you want a 6 person jet spa hot tub, you can also compare tubs that seat six across our brands.
Heat, cold weather and water care
The heater warms water to 104 degrees at roughly 2 to 4 degrees Fahrenheit an hour, depending on the tub and water and air temperatures. Keep the spa cover on while heating. Automatic anti-icing protection needs the tub to stay plugged in. All three have an antibacterial fabric liner. Replacement filters are options on the Mono and Oslo pages.
Compare the soft-walled MSpa tubs
The Comfort Tekapo is square and inflates through its hose. The round Urban Aurora inflates itself and comes with an LED light strip. Both give you bubbles from air jets.

Your questions answered
What makes the Frame Series different from a regular inflatable hot tub?
Wood grain plastic panels lock together around the tub. They hold its shape like a built-in spa, yet it still packs away. Each model seats six and plugs into a standard outdoor outlet, just like the soft-walled tubs.
Which Frame tub has water jets?
The Oslo and Denver have wall nozzles pushing water against your back at three or four seats, plus floor bubbles. The Mono has 138 air jets only. The Oslo holds 304 gallons. The Denver adds the app and a motor designed to run quietly.
Should I pick a Frame tub or the foam-walled Verto Cocoon?
A Frame tub has locking wood grain panels for a built-in spa look and still packs away. The Oslo and the Denver add water jets. The Verto Cocoon has rigid foam panels and air jets only. Pick a Frame tub for looks and water jets or the Cocoon for warmth.
Can a Frame tub stay outside in winter?
Yes, while plugged in, its anti-icing system automatically warms water near freezing to protect the tub and control box. The insulated cover and inflatable insert hold warmth between soaks. Keep your MSpa Frame Series tub plugged in for this protection.
