Four is the number most households actually land on, whether that's two parents and two kids, two couples who host each other, or a family that's outgrown a 2-person tub. The tricky part is that "4 person" describes at least three different Eco Spa shells, each built with a different assumption about how often that fourth seat gets used.
This guide compares the three models that come up for a shopper searching for a 4-person hot tub: the E4, the E1, and the E6 for anyone thinking about room to grow. All specs below come from the current E4, E1 and E6 model pages and our published pricing.
Why "4 Person" Isn't One Tub
Seat counts across the industry run on the optimistic side, so a rating is usually closer to a maximum than to a number of adults who fit comfortably at the same time. That matters more at four than at two, because four adults in the water together take up real space. A model built specifically for 3 to 4, like the E4, spaces those seats with that headcount in mind. A model that stretches to 4 from a smaller base, like the E1's 2-to-4 range, fits four in a pinch rather than as the everyday case. And a model rated well above 4, like the E6's 6 to 7, gives four people room with seats to spare.
Comparing the E4, E1 and E6
| Model | Seats | Jets | Footprint | Water volume | From |
|---|---|---|---|---|---|
| E4 | 3-4 | 21+ | 77" x 60" | 230 gallons | $14,999 |
| E1 | 2-4 | 12 | 72" x 60" | 212 gallons | $11,999 |
| E6 | 6-7 | 21 | 78" x 78" | 325 gallons | $17,999 |
The E4 is the model built for four as the normal case, with 21+ jets across a 230 gallon shell and, as noted on the size guide, the most popular model in the whole lineup. The E1 also reaches four seats, at the lowest price in the lineup, but with fewer jets and a smaller 72 by 60 inch footprint, so it works best when four is the occasional case rather than the regular one. The E6 is a step up in every dimension, a 78 by 78 inch shell holding 325 gallons, which puts four people well inside its comfortable range with two or three seats left for growth or guests.
When to Size Up (or Down) from Four
Size up to the E6 if the household is growing, if gatherings of five or six are becoming routine, or if four is already a tight fit most nights in a smaller shell. The larger 325 gallon volume and 78 by 78 inch footprint give that extra margin. Size down if four is really the ceiling rather than the average, and most nights it's two people: the E2 or E5 cost less to buy and run, and a 3-to-4 model like the E4 is itself a step down in cost and footprint from the E6 while keeping the fourth seat available.
What to Measure Before You Decide
The E4 and E1 share a similar footprint, so a spot that fits one typically fits the other. The E6 is meaningfully larger at 78 by 78 inches, close to a foot wider on each side. Before deciding, check:
- Footprint plus clearance. Add roughly two feet around whichever shell you choose to open the cover fully and reach the equipment panel.
- The delivery route. A spa typically travels on edge, so a gate or side yard needs clearance close to the tub's height, and this matters more for the E6's larger shell.
- Deck load if it's going on a deck. A filled spa with people in it runs roughly 88 to 108 lbs per square foot, and the larger the shell, the more of the deck that weight is spread across. Can a deck support a hot tub has the numbers.
All three sit on any flat, level surface, deck, patio or gravel pad, with no concrete pad, electrician or plumber required for a standard install.
Running Cost at Four Seats
Electricity across the Eco Spa lineup typically runs $10 to $40 a month in BC, and the E4 sits in the middle of that range given its 230 gallon volume. The E1 tends to run slightly lower given its smaller 212 gallon shell, while the E6 sits toward the top given its 325 gallons, so sizing up for headroom does carry a real running-cost trade, just a modest one. Water care is separate: Ecozone ozone sanitation is an available upgrade on most models, and our Ecozone page and the chemical-free hot tub guide explain what it actually does.

Frequently Asked Questions
Which 4 person hot tub works best in Canada?
It depends on whether you want exactly four seats or room to grow. The Eco Spa E4 seats 3 to 4 and is built specifically for that range with 21+ jets. The E1 also reaches 4 seats at a lower price with fewer jets. The E6 seats 6 to 7, which gives a household planning to grow some headroom above four.
What size hot tub fits 4 people comfortably?
The Eco Spa E4 is sized specifically for 3 to 4 people at 230 gallons in a 77 by 60 inch shell. Since seat ratings across the industry run on the optimistic side, four adults tend to be more comfortable in a model rated for that range than in one where four is the stated maximum.
Should I get the E4 or size up to the E6?
If four is close to the real number most weeks, the E4 fits the footprint and running cost better. If the household is growing, or gatherings of five or more are becoming a regular thing rather than a rare one, the E6's 6 to 7 seats and larger 325 gallon volume give more room to work with.
Is the E1 a good budget option for four people?
It can be. The E1 is rated 2 to 4 seats at $11,999, the lowest price in the lineup, with 12 jets. It's a reasonable choice for a household that wants four-seat flexibility without paying for the E4's extra jets, as long as four in the water at once is the exception rather than the rule.
Does a 4-person hot tub cost more to run than a 2-person one?
Somewhat, since there's more water to heat, but the difference is smaller than seat count suggests. Across the Eco Spa lineup electricity typically runs $10 to $40 a month in BC, with the E4 sitting in the middle of that range rather than at the top.
