Engineered for British Weather

Finding an energy efficient 5 seater hot tub that delivers powerful therapeutic massage without causing an unexpected spike in your monthly electricity bills can be a challenge. The award-winning Sunbeach Spas 551-L is designed explicitly to solve this problem for British homeowners.

Measuring 2120 x 2120 x 910 mm, this premium square spa fits beautifully onto suburban patios, terraces, and garden decking layouts without taking over your entire outdoor living space. The interior features a versatile family-friendly configuration, pairing one deeply contoured, full-length hydrotherapy lounger for head-to-toe leg relief with four deep upright seats. It is the ideal layout for intimate family evenings or relaxing social weekend gatherings with friends.

Award-Winning R10 Thermal Insulation Technology

The reason the Sunbeach 551-L stands out as a dream choice for year-round garden use is its award-winning, TÜV-certified Super R10 Insulation System. Standard hot tubs lose massive amounts of heat through their side cabinets, forcing the internal heater to run continuously.

This model features high-density thermal barrier panels wrapped across all four sides and integrated directly into the solid PVC base tray. This advanced insulation traps the ambient heat generated by the electric pump motors inside the cabinet and recycles it straight back into the internal plumbing. This structural engineering dramatically reduces overall power consumption, keeping your water hot and your daily running costs remarkably low through the coldest winter months.

High-Output Hydrotherapy Without Compromising Efficiency

Deep Tissue Massage Power: While this model is an energy efficient 5 seater hot tub, it does not sacrifice performance. Water pressure is driven by a heavy-duty, high-output 3hp massage pump that directs pressurized streams through 28 strategically positioned hydrotherapy jets. This includes 16 rotary massage jets and 12 directional jets designed to melt away shoulder knots and lower back tension.
Low-Wattage Filtration Cycles: To maintain pristine water quality cleanly and quietly, a separate 0.35hp high-flow circulation pump operates independently from the main massage motor. This setup channels water through 2 high-efficiency cartridge filters while an integrated 50mg Ozonator Venturi system introduces natural ozone gas to neutralize organic contaminants, drastically reducing your reliance on manual chemical chlorination.
Reliable Balboa 2kW Heater: Temperature regulation is managed by a dependable 2kW (2000 Watts) Balboa heater pack, ensuring quick heating cycles and steady heat retention.

Flexible Electrical Options: 13-Amp or 20-Amp Setup

The electrical engineering of the Sunbeach 551-L offers great installation flexibility for your property:

13-Amp Plug & Play Mode: This configuration can run directly from a standard outdoor waterproof RCD household socket, avoiding the immediate need for expensive electrical rewiring. In this mode, the smart Balboa control board prioritizes safety by temporarily pausing the 2kW heater whenever the high-power 3hp massage pump is running on high speed.
20-Amp Performance Mode: For an upgraded experience, a certified electrician can hardwire the spa directly to a dedicated 20-Amp supply via an outdoor rotary isolator switch. This configuration permits the 2kW heater and the 3hp massage pump to run simultaneously, ensuring zero drop in water temperature during long, luxurious winter hydrotherapy sessions.

Premium Immersive Entertainment & Ambiance

Under-Shell Hydrosound System: Unlike cheap spas with exposed plastic cabinet speakers that deteriorate in wet weather, this model uses premium Bluetooth Hydrosound transducers hidden entirely beneath the acrylic shell. The system uses acoustic resonance to vibrate the shell structure itself, surrounding you with rich, crisp audio backed by an integrated subwoofer.
Stunning Chromatherapy Package: Transform your garden after dark with 13 colour-changing water-level rail LEDs, a large underwater central light, 4 illuminated cup holders, and striking exterior corner cabinet lighting elements.
Cascading Water Elements: Includes a built-in 490mm sheet-style blade waterfall that provides a gentle, soothing acoustic backdrop to your evening soak.
