A hot tub for four to six people weighs 300–450 kg empty; with water and bathers it climbs past two tonnes. It can be moved — but only empty, blown out, disconnected by a professional and on the right dolly. Nine out of ten cases of damage during a move come down to two mistakes: pulling on the pipework, and laying the shell on its side without support. This guide walks you through the whole process, from draining the water to the first start-up in its new spot.
Why a hot tub is the worst possible load
A hot tub looks like one compact object, but structurally it is a fragile sandwich shell: thin acrylic, a layer of laminate beneath it, insulation on top of that and a load-bearing frame. It is the rigidity of the shape that holds it together, not the material. The moment you support the shell at only two points, its own weight starts working against it.
Add three awkward characteristics. The centre of gravity sits high and off to one side (the motor and pumps are against one wall). The dimensions exceed most gates and doorways. And everything delicate — jets, pipework, control panel — sits around the outer perimeter, which is exactly where anyone trying to grab hold of the tub will reach.
| Type of hot tub | Footprint | Weight empty | Weight filled + bathers |
|---|---|---|---|
| Small, 2–3 people | approx. 180 × 180 cm | 200–280 kg | 1,100–1,400 kg |
| Standard, 4–5 people | approx. 200 × 200 cm | 280–380 kg | 1,700–2,100 kg |
| Large, 6–8 people | approx. 220 × 230 cm | 350–450 kg | 2,200–2,800 kg |
| Swim spa | 400–600 cm long | 900–1,600 kg | 6,000–12,000 kg |
The comparison gives us our first rule: a swim spa is not “moved” in any ordinary sense — it is relocated by crane. For details on handling these large tanks, see our article on swim spa installation and sinking it into the ground.
Preparation: four steps the day before
1. Drain it — and know where those 1,500 litres will go
Draining is not a five-minute job. The gravity drain at the bottom will handle 1,000–1,500 litres in roughly 60–120 minutes; with a submersible pump you are down to 20–30 minutes. Schedule it for the day before, not for the morning of the move.
The key question is where the water will end up. Hot tub water contains disinfectant, stabiliser and residues of pH products, so it cannot simply be sent into a garden pond or onto a flower bed. Let the water stand for 3–5 days without disinfectant so the chlorine dissipates, or route it into the sewer. The exact procedure and the limits are covered in our article on pool water consumption and disposal.
2. Blow the residual water out of the pipework and pumps
This is the step amateur moves skip most often — and the one that costs the most. Even after a perfect drain, 15–40 litres of water remain in the circuits, pump housings and heater. In transit it sloshes about, in storage it goes mouldy, and at the first frost it freezes and splits the plastic housings and the heat exchanger.
The procedure is simple: using a wet vacuum in blower mode, blow out every jet, the suction basket and the drains one by one, until no more water comes flying out. Then loosen the bottom drain plugs on the pumps and heater and leave them open. Put the plugs in a bag and tape it to the control box — hunting for them a month later at the new address is needless misery.
If you are not going to start the tub up straight after the move and it will sit idle through the winter, add antifreeze intended for pool pipework as well. Without it, one night at minus five is enough.
3. Disconnect the electrics — always an electrician
A hot tub is a permanently wired appliance on a dedicated protected circuit with an RCD. Disconnecting it, capping off the outlet and reconnecting it later at the new location are jobs exclusively for someone with the appropriate qualification and inspection certificate — this is not a formality, but a piece of equipment permanently in contact with water. Everything the circuit has to satisfy is summarised in our article Hot Tub and Electricity: Connection Step by Step.
Before disconnecting, photograph the terminal block. That photo will save you half an hour of arguing over wire colours at the new location.
4. Remove the cover and accessories
Take the thermal cover off and transport it separately, laid flat — never place it on the shell as “protection”. Unbolt the cover lifter, steps, handrails and headrests; leave the control panel in place but cover it up. Remove the filter cartridges, dry them and pack them — a damp cartridge in a closed box becomes a source of odour within a week.
Measure the route before you lay a hand on the tub
The classic failed-move scenario: six people holding a hot tub that will not fit through the gate. So walk the route with a tape measure and note down four numbers.
- The narrowest point — the gate, the passage between house and fence, a doorway. A hot tub stood on its side needs the width of its smaller dimension plus 10 cm of margin for the dolly and for hands.
- Corners — at a right-angle turn in a path, the width of the passage is not enough; you also need length to swing the tub round. Measure the diagonal of the free space in the corner.
- Height changes — steps, kerbs, slopes. Every step means stopping, packing out and tipping; with timber blocks and a jack it can be done, it just takes time.
- Ground bearing capacity — on soft lawn or gravel the dolly wheels sink in immediately. Have OSB boards or planks ready and keep laying them down in front of the dolly.
If the measurements say it will not work, there is no point forcing it. Taking down a section of fence or hiring a crane is always cheaper than a cracked shell.
Moving technique: what with, and how many people
The basic tool is a spa dolly — a trolley with a profiled rest against which the edge of the shell, stood on its side, is braced. The tub sits on its strongest point, the frame, and the dolly carries the weight, not the people. Plant hire firms usually stock them; hire charges run at around €12–25 a day.
For lifting it upright, use a low-profile jack or a pry bar together with 10 × 10 cm timber blocks. The procedure is always the same: lift one side by a couple of centimetres, slide a block underneath, move to the other side, repeat. Never lift the whole tub at once.
How many people: four at minimum, six for large models. Not because of the weight — the dolly carries that — but for stability. A hot tub stood upright has the surface area of a sail, and one gust of wind or one person tripping is all it takes. Two people steady the shell, two push the dolly, one watches the route and keeps relaying the ground boards.
Agree on commands in advance, and on one person in charge. Six people all offering advice are more dangerous than four who listen to one.
For inaccessible locations — a hot tub on a roof terrace, behind a house with no vehicle access, on a slope — the answer is called a mobile crane. With textile slings under the frame and a spreader bar, the tub travels through the air in fifteen minutes. The indicative cost of call-out plus an hour’s work is around €160–370; that is incomparably less than a new shell.
Five things you must never do when moving a hot tub
- Pull on the jets, jet handles or pipework. The jet bodies are laminated into the shell and are not designed to take tension. A jet torn loose means a leak you will only discover once the tub is filled — and repairing it requires access to the plumbing from underneath.
- Lay the tub on its side without support. A shell on bare concrete rests on two edges and sags in between. Underneath the side there must always be at least two soft timber blocks or pallets running the full length. Without them the frame breaks and hairline cracks form in the acrylic that only show up a season later.
- Move a hot tub with water in it. Not even “just a little in the bottom”. Water sloshing about shifts the centre of gravity at the worst possible moment, and 100 litres is another hundred kilos.
- Leave it standing on its side for more than a few hours. Brief handling is fine, but a hot tub is not designed for long-term storage on end. At its destination, get it back into a horizontal position as soon as possible.
- Drag the shell along the ground. The base is the thinnest part. A few metres over concrete and it is worn through.
Transport: flatbed, straps and a tarpaulin
For short distances a flatbed trailer behind a car will do; for longer runs, an open lorry with a hydraulic arm. A closed van is usually ruled out by the height of the tub.
Transport the tub lying flat, base down, if the dimensions of the vehicle allow. Underneath it there must be continuous support — pallets or planks — so the base does not rest on the ribs of the load bed. If it has to travel on its side, support the entire bearing edge and secure it against tipping from both directions.
Run the ratchet straps always over the load-bearing frame or over the timber blocks underneath, never directly over the acrylic. A strap tightened with a ratchet will leave a pressure mark on the shell after a hundred kilometres that cannot be removed. Where the straps pass over an edge, put a piece of carpet or a thick blanket underneath.
Finally, the tarpaulin. Not because of rain — because of speed: dust and airflow dull the acrylic, and exposed insulation soaks up moisture. Tension the tarpaulin so that it does not flap.
After the move: what to do before filling
Check that the base is level. The hot tub must sit on the whole surface of its base, not on four corners. Using a two-metre straightedge and a spirit level, verify that the deviation does not exceed 5 mm over 2 m. Never level out unevenness with wedges under the corners — that creates exactly the point loading you have been avoiding all along. The base has to carry roughly 500 kg/m²; if you are moving onto a timber deck, first read up on the structural load of a hot tub on a terrace.
Inspect the connections. Open the service door and go over every union at the pumps, heater and filtration. Transport gives them a thorough shaking. Tighten them by hand — a plastic union nut is not tightened with pliers, it cracks.
Fill and bleed. Run the water in with a hose through the filter chamber, not from above into the tub — this limits air bubbles in the suction pipework. Once filled, loosen the bleed screws on the pumps until water starts to run out, then tighten them again. A pump that starts up with air in it will burn out its seal within minutes. Run the filtration on its own first and let it run for 15 minutes without heating.
Start the chemistry from scratch. The water is fresh, so you begin from zero: alkalinity, then pH, then disinfectant. Do not rely on the values you had at the old location — the new address may have completely different hardness and source pH. The procedure and dosages are covered in our article Hot Tub Chemistry Step by Step.
When to call in the professionals
A specialist moving service makes sense whenever at least one of these conditions applies: the tub is bigger than a five-seater, the route includes steps or a slope, you are not confident about the lifting, or the tub is new and still under warranty. The warranty point is crucial — improper handling is usually an explicit reason for it to be voided.

Frequently asked questions
How long does moving a hot tub take?
A well-drilled team will manage the move itself within the property in 1–2 hours. But allow two days in total: day one for draining (1–2 hours), blowing out (30–60 minutes), disconnection and removal of accessories; day two for the move, positioning, filling and start-up. On top of that, the water takes 12–24 hours to reach operating temperature at the new location.
Can I transport a hot tub on its side?
Yes, but only with the entire bearing edge supported — never on the bare load bed or on two points. On its side it must rest against the frame, not the acrylic, and be secured against tipping from both directions. Lying flat, base down, is always the safer option if the dimensions of the vehicle allow.
What if water is left in the tub and frost arrives?
Residual water in the pumps, heater and pipework expands as it freezes and splits the plastic housings and the heat exchanger. The damage runs into the hundreds or thousands of euros and only shows up at the first filling. That is why blowing it out with a wet vacuum and loosening the drain plugs is a step you cannot skip — it is not a recommendation.
Does moving the tub void the warranty?
With most manufacturers, yes, if the handling is done by someone without the appropriate qualification or if the shell or pipework is damaged. The electrical side may only be disconnected and reconnected by a person with the relevant authorisation and with a new inspection certificate. For a hot tub under warranty it pays to hire an authorised service — the price difference is a fraction of what the warranty is worth.
How many people do you really need?
Four at minimum; for models seating six or more, six is better. The dolly carries the weight, the people provide stability and secure the route. A pair who try to shift a 350 kg shell risk serious injury as well as damage to the tub.
In conclusion
Moving a hot tub is not a question of strength, but of the order of the steps. Drain it, blow it out, have it disconnected professionally, measure the route, brace it against the frame and never against the jets. Anyone who sticks to these six things will move a hot tub without a single scratch — and have it running at its new location by the evening.
If your planning shows that the old tub is not worth the cost of moving — perhaps because it is nearing the end of its life or does not fit the dimensions of the new garden — you will find an overview of current models in our hot tubs category.
