Swim Spa + Hot Tub Combos (Dual Temp)

Hot Tub on the End, or on the Side?

All four of our dual temp models are TidalFit FitSpas, but they split into two layouts. The DT-19 and DT-21 are straight-line units — 19 and 21 feet long with the hot tub on the end. The DTL-6 and DTL-8 are L-shaped swim spas: a 14 ft swim lane with the hot tub connected on the side, which keeps the length of a mid-size spa while adding a full spa zone (total width runs 13′7″–15′2″, so measure for the L). End-style buys you a longer lane; side-style buys you a shorter pad. Either way, each zone has its own temperature — low 80s on the swim side, 104°F on the spa side, at the same time.

Every dual temp we carry offers the WaVS variable-speed swim system, so choosing the hot tub doesn't mean giving up real swimming.

Swim Spa + Hot Tub Combos – Frequently Asked Questions

A single unit with two separate bodies of water: a swim spa zone and a hot tub zone, each with its own heater, controls, and temperature. You can swim at 82°F while the hot tub sits at 104°F — no compromise between exercise and soaking.

You're heating two zones, so operating cost runs above a single body model — but below running a separate hot tub and pool. Full-foam insulation keeps Minnesota winter operation manageable; see the operating cost guide.

Our DTL-6 and DTL-8: a 14 ft swim spa with the hot tub mounted on the side instead of the end, forming an L. You get a true hot tub without stretching to a 19–21 ft footprint — the trade is width, up to 15′2″.
