The Full-Size One
The E6 is the largest tub we build and the only one with a square footprint. 78" by 78" covers about 42.2 square feet, and at 35" it is the deepest in the range. It seats 6 to 7, which is a genuine seven rather than a marketing seven, because the square shape puts everyone at the same distance from the middle instead of stringing seats along a rectangle.
That shape is the reason to buy it. A rectangular seven-seater has a far seat nobody chooses. A square one does not.
Be Honest About the Seat Count
21 jets across 7 seats is three per person. The E3 runs 23 jets across three seats. If hydrotherapy is the main reason you are buying, a smaller tub gives you more of it, and that is worth saying out loud before you spend $17,999.
The E6 is bought for capacity, and capacity is a real requirement: a large family, a household that entertains, a property where four people in the tub is normal rather than exceptional. If that is you, the smaller models will annoy you within a month. If it is not, the money is better spent on jets than on seats, and the E6 Deluxe at 34 jets is the version that does both.
325 Gallons: What Changes
The E6 holds 325 gallons, roughly 60 percent more water than the E3. Three practical consequences:
- Initial fill takes longer to heat. More thermal mass means more energy to bring up from cold. This is a one-time cost each time you drain, not an ongoing one.
- It holds temperature better. Once at temperature, the larger volume under an R-40 cover is more stable through a cold BC night than a small tub.
- Water care scales with people, not gallons. A seven-seat tub used by seven people needs draining sooner than the volume alone suggests. See how often to change hot tub water.
Running cost stays in the same $10 to $40 a month band in BC, because insulation and the cover dominate that figure far more than volume does.
Deck Load: Read This One
This is the model where placement genuinely needs checking. Filled and carrying 7 adults the E6 comes to roughly 4,552 lbs across 42.2 square feet, about 108 lbs per square foot, the highest in the range. That is well beyond what a typical residential deck is designed to carry as live load.
On grade it remains straightforward: compacted gravel, pavers or an existing patio, no concrete pad and no contractor, same as every Eco Spa. On a raised deck, get a structural engineer or a competent builder to look at it before you order, not after. The concrete pad guide covers what actually works.
Access
At 78" square, the E6 needs a wider delivery route than anything else in the lineup. Measure the tightest point between the street and the final position, including gate posts, and send us photos before you order. We would much rather find the problem now. Delivery day covers what to check.
Frequently Asked Questions
How many people fit in the Eco Spa E6?
6 to 7. The square 78" by 78" footprint is what makes seven realistic, because it puts every seat at the same distance from the centre rather than stringing them along a rectangle, so there is no far seat nobody chooses.
Does the E6 have enough jets for seven people?
It runs 21 jets, about three per seat. If hydrotherapy is the main reason you are buying, a smaller tub gives you more of it, or the E6 Deluxe carries 34 jets on the same shell. The E6 is bought for capacity.
Can the E6 go on a deck?
Filled with 7 adults it reaches roughly 4,552 lbs, about 108 lbs per square foot, the highest in the range and well beyond typical residential deck design. Get a structural opinion before ordering. On grade it needs no concrete pad, same as every Eco Spa.
