How Big of a Hot Tub Should I Get?
Picking the right size involves more than just counting seats. There are several practical factors to weigh before you commit to a model.
How Many People Will Use It?
Consider your household size alongside any regular guests. While it's possible to spread out in a smaller tub, being able to sit comfortably makes for a far more enjoyable experience — for everyone.
Where Will It Be Located?
Choose a spot that can structurally support the weight of a filled tub. If you're uncertain about the foundation, your nearest dealer can offer tailored guidance based on your outdoor setup.
Maintenance Access & Foundations
As a general rule, leave at least 60cm of clearance on three sides of the tub for maintenance access. For the access door itself, around 40cm of clear space should be sufficient.
Accessibility
For a two-person tub this rarely presents a challenge. For larger spas, however, ensure there's enough room for everyone to move freely — no one wants to squeeze past each other to get in or out.
Cover Lifter Clearance
If you plan to use a cover lifter, factor in the additional clearance needed on at least one side. This is especially worth planning for if you intend to build a surround or housing structure around your spa.
Delivery Access
Before placing your order, confirm your measurements with the delivery team. Ensure the route to your garden is clear, with plenty of room — paying particular attention to low-hanging branches, tight corners, and other obstacles that could affect access.
