Planned properly, because it weighs most of a tonne.

Delivery is included in the price for all mainland Britain addresses, on every product we sell. There is no minimum order, no separate handling fee and nothing added at the final step.

The Scottish Highlands and Islands, Northern Ireland, the Isle of Man and the Channel Islands are quoted individually, because the cost genuinely differs and we would rather tell you the real figure than average it into everybody else's price. Ask us before you order and we will give you a firm number.

Before anything leaves a manufacturer we will ask you where the largest vehicle that can reach you would park, the narrowest width and lowest height along the route to the spot, what the ground is and how it behaves when wet, whether there are steps, and who will be there on the day.

Photographs help more than measurements. A picture of the side passage answers in two seconds what a list of dimensions takes ten minutes to establish.

Where a route genuinely will not work there are honest options: track mats over grass, a different approach, a hired lift, or a crane. A crane sounds dramatic and often is not. We will price it rather than dismiss it.

Every product page carries its own lead time, and we quote it as our experience says it really is rather than as the manufacturer's best case. An honest twelve weeks is a better experience than an optimistic eight that becomes fourteen, and it lets you book your groundworks and your electrician for the right week.

If a lead time changes after you order, you hear it from us the day we hear it, not the week it was due.

Deliveries of this size are kerbside by default: the item comes off the lorry to a safe point at your property. Where the manufacturer offers placement, siting or installation we will tell you on the product page and arrange it at the time of order rather than afterwards.

Someone needs to be there. Please have the route clear, and a plan for where the packaging goes.

Check the equipment before the driver leaves. If anything looks wrong, photograph it and tell us the same day. A claim raised immediately is a straightforward conversation. One raised three weeks later is not.

The base should be finished and cured before delivery, not after. A sauna wants a level, free draining base with air movement underneath. A plunge wants a base rated for the filled weight, which is a great deal more than the empty weight: water is a kilogram a litre, so a six hundred litre plunge is more than half a tonne before you count the shell.

Electrical work also wants doing beforehand. An electric heater above a certain rating, and any chiller unit, needs a suitable outdoor supply installed by a qualified electrician. That job has a lead time of its own, so book it early.
