The Family Version of the Best Seller
The E4 is the E3's shell, reconfigured for more people. Identical 77" by 60" footprint, identical 33" depth, identical 230 gallons, identical 470 lbs dry weight. What changes is the seating: 3 to 4 places instead of 2 to 3, with 21+ jets arranged to serve them.
That matters because it means you do not pay a footprint penalty for the extra seat. Going from the E3 to the E4 costs $200 and zero additional square footage in your yard. Going from the E4 to the E6 costs $3,000 and another 10 square feet.
What Four Adults Actually Means
Seat counts across this industry are optimistic. 4 in the E4 is 4 real adults, but it is 4 adults sitting sociably, not 4 adults each with a lounger. If your normal use is two people and the fourth seat is for the occasional visitor, the E3 with its 23 jets across fewer seats gives each person more.
If four of you will be in it most weekends, this is the right tub and the E3 will feel tight. The deciding question is the ordinary Tuesday, not the party.
Deck Load: the Number That Changes
This is the one place the E4 genuinely differs from the E3 despite the identical shell. Filled and carrying 4 adults it comes to roughly 3,108 lbs over 32.1 square feet, about 97 lbs per square foot, against the E3's 91 lbs per square foot at its rated occupancy. Same tub, more people, more load.
On a ground-level patio, on pavers or on compacted gravel this is irrelevant and no concrete pad is required. On a raised deck, size the question on 4 people rather than on the empty tub, and get a structural opinion. What surfaces work covers it.
Running It
230 gallons behaves the same as the E3: enough thermal mass to ride out a cold night under the R-40 hard cover, quick enough to recover after a full house. Roughly $10 to $40 a month in BC.
Where four people does change things is water care. Bather load is the single biggest driver of how long a fill lasts, so a family E4 will want draining more often than a couple's E3 on the same volume. How often to change hot tub water has the schedule by household.
What You Are Not Giving Up
Same one-piece HDPE shell, same R-40 lifetime hard cover, same lifetime shell warranty, same 5x filtration, same 110V and 220V convertibility as every other model. At $14,999 the E4 is priced in the middle of the range, not at the top, because seating four is a layout decision here rather than a bigger machine.
Frequently Asked Questions
How many people fit in an Eco Spa E4?
3 to 4 adults, sitting sociably rather than each with a lounger. If your normal use is two people with an occasional guest, the E3 gives each person more jet coverage for $200 less.
Is the E4 bigger than the E3?
No. Identical 77" by 60" footprint, 33" depth, 230 gallons and 470 lbs dry. The E4 seats more people in the same body by changing the seating layout, so the extra seat costs you $200 and no additional yard space.
What does the E4 weigh when full?
About 2,388 lbs filled, and roughly 3,108 lbs with 4 adults in it, which is about 97 lbs per square foot over 32.1 square feet. Size any raised deck on the occupied figure, not the empty one.
