For most Irish households a 4–5 seat hot tub, around 2.0 × 2.0 m, is the right size. Couples and small gardens suit a 2–3 seater around 1.8 m wide, while families who entertain often should look at 6+ seats from about 2.2 m. Always allow extra space around the tub for the cover and safe access.

Five questions to ask
- Who will use it most evenings? Size for everyday use, not the once-a-year party.
- Do you want a lounger? It is comfortable but takes up about two seats.
- How much space do you have? Add about 60 cm each side for the cover lifter and walkway.
- Can it get in? Measure gates, side passages and steps. Tubs travel on their side.
- Can the base take it? A filled 5-seat tub with bathers can weigh over 2 tonnes.
Bigger isn’t always better
A larger tub holds more water, so it costs more to heat and to buy. If it is mostly two of you, a well-designed 3-seater with a lounger will feel roomy and cost less to run. Compare models on our hot tubs for sale page.

Frequently asked questions
How much space do I need for a hot tub?
The tub footprint plus around 60 cm on each side, so roughly 3 × 3 m for a typical 4–5 seat tub.
How heavy is a hot tub when full?
A 4–5 seat tub with water and bathers typically weighs 1.5–2.5 tonnes, so it needs a strong, level base.
Is a 2-person hot tub big enough?
For couples, yes. If you plan to have family or friends in regularly, a 4-seater is more flexible.
