Buying guide

How to choose a hot tub in South Africa

Seats, jets, power supply and base — the four decisions that actually determine whether you enjoy the thing. Everything else is detail.

1. Start with the base, not the brochure

The most common expensive mistake is choosing a model and then discovering the surface will not carry it. A four-seat hot tub filled with water and people weighs comfortably over 1 500 kg; a six-seater more; a large swim spa several tonnes. That load has to sit on something rated for it — a reinforced concrete slab, or decking specifically engineered for the weight, not a standard timber deck built for garden furniture.

Measure the space, then measure the route to it. Gate widths, corner radii, overhanging eaves and stair landings kill more hot tub deliveries than anything else. If your only access is a 900 mm side passage, a 2 500 mm shell is not happening regardless of budget.

2. Decide the supply before the size

South African homes come in two flavours for this purpose. Standard 220 V single phase runs compact and mid-size hot tubs, spa baths, infrared cabins and steam rooms. Larger units — swim spas from about four metres, six-seat spa baths with dual heating, premium steam enclosures — need 380 V three phase, which many suburban properties simply do not have without an application and upgrade.

Check your distribution board before you fall in love with a model. Every product page on this site lists the supply requirement under Additional Information, and we confirm it during the free site survey.

3. Seats: be honest about usage

People routinely buy one size larger than they use. The realistic pattern for most households is two adults on a weeknight and four or five occasionally. Every extra seat costs money three times over: purchase price, water volume to heat, and chemicals to treat.

• 2 seats — balconies, townhouses, couples. The Compact 2 fits where nothing else will.
• 3 to 4 seats — the sweet spot for most families. The Serenity 4 is our best seller for a reason.
• 5 to 6 seats — you genuinely entertain, and you have the slab and the supply for it.
• 7 to 8 seats — swim spa territory, with the access planning and three-phase supply that implies.

4. Jets: placement beats count

Jet count is the number most heavily marketed and the least useful in isolation. Forty jets spread evenly across a shell gives you forty mediocre massages. Forty jets grouped into dedicated therapy seats — one aimed at the neck and shoulders, one at the lumbar spine, one at calves and feet — gives you four good ones.

Ask where the jets are, not how many. And be slightly suspicious of very high counts on small shells: more jets on the same pump means less pressure at each.

5. Insulation and cover: where the running cost lives

Two hot tubs of identical size can differ by hundreds of rand a month purely on insulation and cover quality. A fully insulated cabinet and a well-fitted, locking thermal cover with a gas lifter will pay for themselves inside two winters. A cheap foam cover that has absorbed water is the single most common reason an owner’s bill jumps.

Our running costs guide works through the arithmetic.

6. Water care: choose your maintenance appetite

Every tub needs weekly testing and dosing, filter rinses and a drain-and-refill every three to four months. Models with UV-C sanitation reduce the chemical load meaningfully. If you know yourself to be the sort of person who will not test weekly, buy the UV-C model — it is cheaper than replacing a shell damaged by neglected water chemistry.

7. Consider whether electricity is the right answer at all

If load-shedding is frequent where you live, or you are on a smallholding where trenching a cable is a project in itself, wood fired tubs sidestep the problem entirely. No pump, no element, no meter. They take two to three hours to heat and need a supply of dry wood, which suits some households perfectly and others not at all.

8. Warranty: read what it excludes

Shell warranties of five years and component warranties of two to three are normal on premium units. What matters is the exclusions — installation by an unregistered electrician, chemical imbalance, freezing and transport by third parties are all commonly excluded. Ours are set out in the returns and warranty policy.
