WOODBRIDGE 60″ Heated Jetted Tub
This alcove-style tub combines a heated soaking system with adjustable water jets. The inline heater auto-activates with the pump to maintain target temperature up to the specified limit. The layout includes 3 foot-zone jets and 6 body-zone jets with adjustable angles for targeted hydrotherapy.
Materials are acrylic with a polished chrome finish available on trim. Dimensions indicate a spacious exterior while the inner seating and depth measurements provide clarity for fit and comfort. Intended uses include therapeutic soaking and combined jetted massage sessions where sustained warmth is important for extended relaxation.
Features to note from the manufacturer: inline heater that heats to a set limit, multiple adjustable jets across foot and body zones, and specific exterior/interior dimensioning for installation planning. This model is suited to buyers prioritizing built-in heating control integrated with jet therapy.

This freestanding combination tub integrates whirlpool and air bubble jets with an inline heater controlled via an LED panel. The inlet heater extends comfortable soak times without frequent reheating, while the LED system provides operational control for jet modes and temperature settings.
Large exterior dimensions and a substantial effective capacity are provided, making this option appropriate for users seeking a full-featured spa-style freestanding tub. The design supports both water and air massage therapies, giving multiple therapeutic modalities in one unit.
Manufacturer features emphasize the combination of whirlpool + air bubble jets and a heater that allows maintaining water temperature through an extended bath. Consideration points include installation footprint, electrical requirements for pump/heater/LED system, and seating dimensions relative to user height.
MEDUNJESS 51″ Resin Deep Soaking Tub
This freestanding Japanese-style soaking tub is crafted from a 60% organic rock and 40% high-tech resin blend, promoted as an eco-friendly solid surface. The matte finish provides a natural stone feel with a non-slip surface and ergonomic contours for lumbar and head support.
The design emphasizes deep immersion and comfort rather than integrated heating or jetted systems. For users desiring heat retention without a built-in heater, the solid surface construction and insulation characteristics can help retain warmth longer than thin acrylic tubs.

Key manufacturer features include recycled content in the material mix, a non-porous matte surface for tactile comfort, and ergonomic shaping for full-body soaking. This tub is best for buyers seeking a natural stone aesthetic and deep soak in a freestanding profile.
Weibath 47″ Stone Resin Soaking Tub
The Weibath 47″ tub is a freestanding oblique-shaped soaking tub made from stone resin. It focuses on deep soaking with ergonomic contours that cradle the body. The matte white finish provides a contemporary look suitable for minimalist or modern bathrooms.
This model emphasizes durability and low maintenance inherent to stone resin construction. The product features list highlights the oblique design, deep soaking capability, and a finish intended to resist wear with minimal upkeep.
Although the manufacturer description does not specify an integrated heater, the stone resin build supports heat retention better than thinner materials. Consider pairing with an external inline heater system if continuous warm water is a priority in a freestanding installation.
Empava 59″ Air Jetted Soaking Bathtub
The Empava 59″ model features 48 air pinhole jets driven by a 0.5 HP air pump to create micro-bubble hydrotherapy. It offers a deep 21-inch soaking depth with a pre-molded seat and Japanese-inspired space-saving shape.
This tub emphasizes gentle full-body massage via air jets and a deep immersion profile. The air-jet system fosters a spa-like bubble experience, while the design remains compact enough for smaller bathrooms seeking therapeutic soak capability.
Manufacturer highlights include the high jet count for even micro-bubble distribution and a design optimized for deep soaking without taking excessive floor space. If sustained warm-water temperature is required, verify whether the model includes an inline heater or plan for external heating solutions.
Buying Guide: Choosing A Japanese Soaking Tub With Heater
Selecting the right tub requires balancing soaking depth, heat retention or heating capability, materials, installation demands, and therapeutic features. Use the following perspectives to compare models objectively.
Soaking Depth and Interior Dimensions
- Depth: Japanese soaking tubs emphasize vertical immersion. Look for water depth measurements (e.g., 14″+ water depth or 21″ seat depth) to ensure shoulder-level submersion for your height.
- Seat And Ergonomics: Check internal seating contours and lumbar support if you prefer a sit-in posture rather than reclining.
Heating Options And Heat Retention
- Inline Heaters: Built-in inline heaters maintain set water temperatures during a soak. Verify maximum temperature, auto shutoff behavior, and compatibility with jet systems.
- Material Heat Retention: Solid stone resin and thicker acrylic retain heat better than thin acrylic shells. If a tub lacks a heater, material choice affects how long water stays warm.
- Electrical Requirements: Heated tubs and pumps require dedicated circuits and appropriate wiring. Confirm voltage, amperage, and local code compatibility.
Hydrotherapy Features
- Air Jets vs. Water Jets: Air jets provide gentle, full-body micro-bubble massage; water jets offer stronger targeted hydrotherapy. Both may be paired with heaters, but verify combined operation limitations.
- Adjustability: Jets with directional and flow adjustments allow targeted therapy. Consider how many zones (foot, body, back) are included.
Material, Finish, And Durability
- Stone Resin/Solid Surface: Offers a matte, natural feel with good heat retention and non-porous surfaces. These are heavier and may require reinforced flooring.
- Acrylic: Lighter and often used in jetted tubs. High-gloss acrylic can be easier to clean but may not retain heat as well as stone resin.
- Surface Care: Look for non-porous finishes that resist staining and yellowing.
Installation And Space Considerations
- Freestanding vs. Alcove: Freestanding tubs offer placement flexibility but may need access panels for service. Alcove tubs fit existing alcoves and often integrate plumbing more directly.
- Footprint And Clearance: Measure the bathroom carefully for doorways, turning radii, and final placement. Include installer access for lifting heavy stone-resin tubs.
- Plumbing And Electrical Access: Heated, jetted, and pump systems require both water and power access. Confirm where controls will be mounted and how wiring will be routed.
Maintenance And Serviceability
- Jet System Cleaning: Jetted systems need periodic cleaning cycles. Verify manufacturer recommendations for sanitizing lines and preventing buildup.
- Access Panels: Ensure service access for pumps and heaters without removing the entire tub in case of repairs.
Comparison Perspectives
- Therapy-Focused Buyer: Prioritize tubs with integrated heaters and adjustable water jets (e.g., the Woodbridge models) for continuous warm hydrotherapy sessions.
- Aesthetic And Heat Retention: If material feel and natural appearance matter, stone resin freestanding models (MEDUNJESS, Weibath) offer better passive heat retention and tactile quality.
- Space-Conscious Buyers: Compact Japanese-inspired shapes with deep seats (Empava, smaller stone resin tubs) deliver full immersion in a smaller footprint.
- Installation Practicality: Consider alcove tubs when replacing an existing alcove installation; freestanding units require additional floor support planning.
When evaluating options, verify manufacturer-specified heater compatibility, jet integration, installation requirements, and service access to align performance expectations with your bathroom constraints and therapeutic goals.
