WOODBRIDGE 72″ Whirlpool Heated Soaking Tub
Type: Freestanding whirlpool and air bubble bathtub with LED control panel.
This WOODBRIDGE model lists an exterior size of 72″ x 35-3/8″ and an effective capacity of 65 gallons. It includes a pre-installed tub filler with handshower, which streamlines installation by reducing on-site faucet assembly. The tub combines whirlpool and air bubble jets for hydrotherapy, and a built-in inline heater maintains water temperature during prolonged soaks. Power requirements specify a dedicated 120V 30A circuit, so confirm electrical capacity during planning. The LED control panel provides temperature and jet control options.

Titikula 1800W Immersion Water Heater
Type: Portable immersion heater for bathtubs, buckets, and small pools.
This immersion unit provides 1800W of heating power and includes an adjustable thermostat with real-time temperature display. Safety features include auto shutoff and anti-dry-burn protection. The heating rod is stainless steel and the cord is reinforced for durability. The controller is designed to keep water near a set temperature by cycling on when the temperature drops. As a portable option, this device is suitable for retrofitting existing tubs without a built-in heater, emergency heating situations, or supplemental warming for larger volumes that take long to heat through conventional plumbing.
Buying Guide: Choosing A Bathtub With A Heater
Selecting the right heated bathtub involves evaluating fixed-feature tubs and portable heating options. The considerations below address compatibility, safety, performance, and installation.
Heating Method And Performance
- Inline/Integrated Heater: Built into the tub system, maintains water temperature during use and often controlled through the tub’s control panel. Best for seamless aesthetics and continuous warmth.
- Immersion Heater: Portable and versatile; can be used with existing tubs or small pools. Provides fast spot heating but requires careful supervision and safe operation procedures.
- Power And Recovery Rate: Higher wattage heats faster. For immersion heaters, 1800–2000W provides rapid heating for small volumes; built-in inline heaters are sized to sustain temperature rather than rapid fill heating.
Installation And Electrical Requirements
- Dedicated Circuits: Many freestanding tubs with heaters and pumps require a dedicated 120V or 240V circuit. Confirm breaker size (some list 30A) and consult a licensed electrician.
- Plumbing Compatibility: Pre-installed fillers reduce installation complexity. Alcove tubs with tiling flanges simplify surround installation.
- Space And Access: Measure doorways and alcove spaces. Freestanding tubs need floor reinforcement planning when weight and water capacity are high.
Controls, Safety, And Certification
- Control Interface: LED panels provide temperature and jet controls. Check user interface clarity and placement for ease of use.
- Safety Features: Look for auto shutoff, dry burn protection, and UL certification for immersion heaters. For installed systems, ensure GFCI protection on circuits servicing heaters and pumps.
- Maintenance: Jet nozzles, filters, and trim finishes require periodic cleaning. Smooth acrylic shells reduce buildup and simplify upkeep.
Therapy And Comfort Considerations
- Jet Configuration: Number and placement of jets influence massage coverage—look for foot and body zones if hydrotherapy is important.
- Seating And Depth: Interior seating length and water depth determine ergonomic comfort. Compare seating dimensions against user height.
- Water Capacity: Larger capacities provide immersion but add weight; factor in structural support and water heating energy needs.
Portability Versus Integrated Systems
- Integrated Systems: Offer unified controls and cleaner aesthetics; ideal when renovating or building a bath space with dedicated electrical/plumbing.
- Portable Immersion Heaters: Cost-effective for adding heat to existing tubs or for travel. Require manual placement and attentive safety practices.
Energy Use And Long-Term Costs
- Energy Efficiency: Inline heaters maintain temperature to avoid repeated hot water fills, which can be more efficient for long soaks.
- Operating Cost: Immersion heaters deliver quick bursts of heat; compare how often you’ll use supplemental heat versus continuous inline heating to estimate long-term cost.
Comparative Perspectives
- Home Renovation Perspective: Choose an integrated heated tub when remodeling; plan electrical upgrades and ensure space fits tub dimensions and plumbing hookups.
- Retrofit Or Budget Perspective: Use a certified immersion heater to add heating capability to an existing tub without structural changes.
- Therapeutic Perspective: Prioritize jet layout and heater consistency if you plan frequent hydrotherapy sessions; models with combined whirlpool and air bubble systems provide varied massage sensations.
When comparing options, match heater type to usage pattern (long soaks vs. occasional heating), confirm electrical/plumbing compatibility, and prioritize safety features such as auto shutoff and GFCI protection.
