Fiberglass Round Hot Tub

Fiberglass Round Hot Tub

The MWT4 Wood-Fired Hot Tub is a premium outdoor hot tub handcrafted in Lithuania, combining traditional European craftsmanship with efficient wood-fired heating and modern comfort. Designed to accommodate up to four people, the MWT4 creates a spacious outdoor retreat without requiring an electrical connection. The ergonomically contoured fiberglass interior features a refined white mother-of-pearl finish, while the exterior is crafted from Scandinavian ThermoWood® for enhanced durability, dimensional stability, and resistance to outdoor conditions. A self-cleaning corrugated wood-fired stove provides efficient heating, while the dual-flow circulation system draws cooler water from the base and redistributes heated water from above to promote a more consistent bathing temperature. With approximately 317 gallons of water capacity and a heat-up time of approximately 1.5–2 hours from 40°F to 95°F, the MWT4 delivers a simple, nature-inspired outdoor soaking experience.

About Rodeo

At Rodeo we're on a mission to create the best saunas in the world. It all started with a simple realization - existing brands were either overpriced or cheap knock-offs.

So we built the brand we wished existed. A perfect balance of great materials, honest craftsmanship, and clean design at a fair price. We focus on what actually matters - crafting great products that hold up to real, everyday use.

We build with the belief that products should become part of your routine, not end up in a landfill. No trends. No gimmicks. Just great saunas, made the right way by people who care about their craft.

We make saunas for folks who deeply love the art of rest, recovery and relaxation after a hard days work.
