If you are searching for a high-performance 72-inch freestanding bathtub that offers professional-grade hydrotherapy, the Woodbridge BJ400 is a top contender. Unlike standard soaking tubs, the BJ400 is a "dual-system" powerhouse, combining vigorous water jets with soothing air bubbles.
In this 2026 expert review, we break down the real-world performance, heat retention, and the technical specs you need to know before your remodel.
The Direct Answer: Why the BJ400?
The Woodbridge BJ400 is the ideal choice for homeowners who want a "no-compromise" spa experience. It is one of the few freestanding models that includes a 1.0 HP whirlpool pump, a built-in heater, and an air blower in a single, sleek 72-inch frame.
Key Performance Features
The Dual-Massage System The BJ400 features a hybrid massage system that addresses two different recovery needs:
Deep Tissue Relief: 6 adjustable hydro-jets target high-tension areas like the lower back and legs.
Full-Body Relaxation: 10 air jets release thousands of warm bubbles that oxygenate the skin and soothe the nervous system.
Automatic Inline Heater
One of the biggest complaints with large 72-inch tubs is that the water cools down before you're finished. The BJ400 includes an inline water heater that maintains your temperature at a steady 104°F while water is circulating through the jet system, allowing for extended, uninterrupted soaking sessions.
Premium Construction
This tub is crafted from high-gloss Lucite® acrylic reinforced with fiberglass and Ashland resin. This high-end material is non-porous and highly resistant to stains, scratches, and fading, ensuring it retains its "showroom" look for years.

Customers Also Ask:
Does the Woodbridge BJ400 include the faucet?
No, the BJ400 does not include a faucet. You will need to purchase a freestanding tub filler or a wall-mounted faucet separately.

Yes! The Woodbridge BJ400 is also offered in black and brushed gold finishes.
