The 3-person SX spa comes complete with a Moto-Massage? jet and all of the outstanding features that normally come in a full-size Hot Spring spa. This model includes a No-Fault? heater and FiberCorTM insulation. If you want a quality spa that fits easily into a small space, consider the SX small hot tub and TX corner hot tub models. Compact enough for a second floor deck, yet roomy enough for you to stretch out and relax, the SX and TX models are ideal choices for a first hot tub or changing lifestyles.
