Why This Is the One Most People Buy
The E3 sits at the point where footprint, jet count and price stop fighting each other. At 77" by 60" it takes about 32.1 square feet, which fits the majority of BC decks and patios without redesigning the yard. It carries 23 jets, the most of any non-Deluxe model in the range, including more than the seven-seat E6. And at $14,799 it is the middle of the lineup rather than the top.
It seats 2 to 3. In practice that is two people in comfort with room for a third, which describes how most hot tubs actually get used once the first summer is over.
23 Jets Across 3 Seats
Jet count on its own is a marketing number. Jets per seat is the useful one. The E3 puts 23 jets across 3 seats. The E6 puts 21 across seven. If hydrotherapy is a real reason you are buying rather than a nice-to-have, that ratio is the argument for the E3 over anything larger, and it is why this model outsells the rest.
It combines lounge seating with deep bucket seats, so two people can use it differently at the same time, which the strictly two-person models cannot do.
E3 vs E4: the Honest Answer
These two share a shell. Same 77" by 60" footprint, same 33" depth, same 230 gallons, same 470 lbs dry, and only $200 apart. What differs is the seating layout and the jet arrangement: the E3 runs 23 jets across 2 to 3 seats, the E4 reconfigures the same body for 3 to 4 with 21+ jets.
So the choice is not size or cost, it is people. Buy the E3 if the tub is mostly for two with an occasional third and you want the jets concentrated. Buy the E4 if four adults will genuinely be in it. Nobody should agonise over the $200.
Deck Load and Placement
Filled and occupied by 3 adults, the E3 comes to roughly 2,928 lbs across 32.1 square feet, or about 91 lbs per square foot. That is above what a typical residential deck is designed to carry as live load, so on a raised deck get a structural opinion first. On grade, on gravel, pavers or an existing patio, no pad and no contractor is needed. See do you need a concrete pad.
Running It
230 gallons is a moderate volume: enough thermal mass to hold temperature well overnight under the R-40 cover, not so much that recovery drags after heavy use. Roughly $10 to $40 a month in BC. Ships wired for both 110V and 220V, so the electrical decision is not bundled into the model decision. See 110V vs 220V.
