Get the durability of a permanent hot tub without the builders, the concrete base, or the installation bill. The Lay-Z-Spa® Monte Carlo HydroJet Pro™ is a rigid wall hot tub that brings hard-shell durability together with genuine plug-and-play simplicity. It delivers all the premium features of a permanent spa — hard acrylic shell, proper jets, thermostatic heating — without the cost, complexity, or specialist installation that traditional acrylic hot tubs usually require. Ideal for anyone wanting permanent-spa quality without a permanent installation, and perfect for gardens or patios where a built-in hot tub isn't practical, the Monte Carlo is backed by a genuinely substantial warranty rather than a token one.
Available in 3 or 5-person sizes, the Monte Carlo is built around a rigid acrylic shell with wood-embossed skirting, giving it the look and feel of a much more expensive built-in spa. The signature HydroJet Pro™ dual massage system combines 14 AirJets™ with 12 directional water jets, delivered through ergonomic, custom-moulded seating with integrated foam pillows for genuinely comfortable long soaks. Colour-changing LED lighting sets the mood after dark, while a premium insulating lid with thermostatically controlled heating keeps the water at temperature between sessions. Everything runs through a 2HP dual-action HydroJet Pro™ pump that's fully removable for servicing, and smart WiFi app control lets you manage temperature, scheduling and massage settings remotely — so it's ready to soak in the moment you get outside. Freeze Shield™ technology keeps it usable year-round.
