Paddle out. Paddle back. Sink in.

Yes. The heater dials the spa to your chosen soak temperature; turn it off and the water settles to ambient (properly cold in winter, cool in summer). Plenty of customers use the MSpa as a cold plunge after intense sessions, then re-engage the heater when they want the spa warm again. One unit, both jobs — but note the cold side is ambient, not refrigerated.

The Tidal-Eco. It pairs the standard MSpa air-jet ring (138 jets) with three SyncJet hydromassage nozzles that produce a directional water-and-air massage — strong enough to actually work into the shoulder, lat and upper-back tightness that paddling builds up. The Cocoon-Eco has 130 air jets if you want a slightly gentler version.

Dave Clark, the owner of Portable Spas NZ, had his first MSpa sitting next to his caravan on the hillside at Ahipara. It's now on the deck looking out to Shippies and up Ninety Mile Beach — nearly six years old and still running. He'd say MSpas handle New Zealand's salt air with ease. To make a coastal spa last: keep the cover sealed when you're not in it. The control unit also lifts cleanly off for indoor storage between trips if you'd prefer to be careful, and replacement parts are stocked in NZ.

Yes — and your filter, your control unit and your spa liner all thank you for it. Sand, sunscreen and salt are hard on every part of a spa: they clog filters, dull the liner over time, and can find their way into the electronics. A quick freshwater rinse outside the spa before stepping in is the single simplest habit that protects all three. Cartridges are designed to be replaced every 4–6 weeks under regular use anyway.

From a cold fill, an MSpa typically takes 12–24 hours to reach full temperature depending on model and ambient conditions. The Cocoon-Eco is the fastest heater in the range at 1.9–2.6°C per hour. Most surf-household customers leave the spa on at temperature with the cover sealed — it's more energy-efficient than letting it cool down and reheating from scratch.

Yes — that's the point of portable. Deflate, drain, pack into the boot. At the other end you need a flat patch of deck with 60cm of clearance, a 10-amp socket, and a garden hose to fill. From there it's 10–15 minutes to inflated and filling. Plenty of customers run their spa between a town home and a coastal bach across the year.

Yes — every MSpa in the Verto and Frame series, including the Oslo, Cocoon-Eco, Rova, Denver, Tidal-Eco and the Mono range, includes WiFi and remote management through the MSpa app on your phone. Turn the spa on from the road on the drive up so it's at temperature by the time you walk through the door at the bach.

Yes — with adult supervision and the family setting of 38°C (rather than the full 40°C) for younger kids. Cocoon-Eco includes a safety-lock cover and an anti-slip floor; the Oslo includes a six-point safety cover. One thing to know: every MSpa cabinet sits under 76 cm, which is the threshold NZ regulations use for fencing requirements. The simple solution is to sit the spa on up to 100 mm of high-density foam or polystyrene — that raises the effective side height to the regulated 76 cm, and it doubles as floor insulation that improves comfort and reduces running cost.
