Spa covers are sized to both shape and capacity. A 6-person spa cover won't fit an 8-person spa, and a round spa cover won't fit a square model. We stock thermal covers and full spa covers in 6-person round, 6-person square, 8-person round, and Oslo sizes — match the cover to your specific spa. If you're not sure which spa model you have, check the model name on your control panel or original packaging, or email sales@portablespas.co.nz with a photo and we'll identify it.

A full spa cover is lightweight and designed to keep dust, leaves, and rain out of the spa when it's not in use — it's more about general protection than insulation. A thermal cover is heavier-duty, with a denser core built to minimise heat loss and hold the water temperature between sessions. If energy efficiency matters to you, go thermal. If you just want something to throw over the spa when it's not being used, a full cover is fine.

Yes — a well-fitted thermal cover can cut your spa's running costs by up to 50%. Heat loss happens fastest from the water surface, so keeping the cover on between sessions is the single biggest thing you can do to keep power bills down. Pair the cover with a foam mat underneath and you'll see further savings, especially through winter.

Absolutely — MSpa portable spas have built-in anti-icing protection and are designed for year-round NZ use. To get the most out of winter soaks, we recommend three accessories working together: a thermal cover (essential), a heat preservation foam mat under the spa, and an inflatable insulation bladder on top of the water for an extra thermal layer. Many of our customers say winter is when their spa earns its keep.

The bladder sits on top of the water surface, under the spa lid. It creates an insulating air layer between the hot water and the cover, which slows heat loss and helps with rainwater runoff. One thing to note — don't over-inflate it. The hot water will heat the air inside the bladder and cause it to expand, so leave a bit of slack. Bladders are spa-shape-specific, so make sure you order the right one for your model (round, square, or Oslo).

If your spa lives outdoors and you want it to feel like a permanent feature rather than an inflatable, yes. Wicker surrounds add storage for towels and chemicals, integrate steps for easier access, and instantly lift the look of the setup. We stock 3-piece sets for both round MSpa models and square models, plus individual pieces (steps, open storage, cabinets) if you want to build it up gradually.

No. The Kokido EV02 rechargeable spa vacuum works underwater, so you can use it on a full spa without draining anything. It's designed to lift sand, leaves, and small debris off the spa floor — a quick once-over before each soak makes a noticeable difference, especially if your spa lives outdoors.

The shape-and-size-specific ones don't — thermal covers, full spa covers, and insulation bladders are sized to your specific MSpa model (round vs square; 4, 6, or 8-person). Wicker surrounds come in round and square versions to match your spa shape. The Cup Holder & Headrest is designed specifically for the Mono range. The cushion twin pack, the cleaning kit, the spa vacuum, and the floating light work across any portable spa. If you're unsure, email sales@portablespas.co.nz with your spa model and we'll confirm the right fit.
