100% Wood Bathtubs, OFURO Japanese Soaking Tubs & Washbasins. How They Are Made?
Our products are made from the finest quality varieties of hard European, Asian and African wood. The material used to manufacture a bathtub must have the right structure and a unique look. The wood achieves an optimal structure, moisture content and hardness due to additional seasoning in open air conditions for several years and subsequent proper mechanical drying. The selected wood species from which bathtubs are made are characterised by high resistance to weather conditions.
STABLE
STRUCTURE
The manufacturing process starts with the selection of wood that complies with the technical and aesthetic requirements. Only hard and stable wood with a low shrinkage coefficient is suitable for use. The bathtub elements are layered together and then pressed. Wood that has been glued in such way is characterised by high form-holding ability even under varying temperature and humidity conditions. Such structure considerably inhibits the natural expansion and shrinkage of wood. The layers of real wood are glued with a special waterproof adhesive that makes the bathtub totally leak proof.
SURFACE
We protect our products’ surfaces with special OSMO wax oils made from natural ingredients to ensure high and natural quality. These preservatives are resistant to dirt and abrasion and are eco-friendly.
1. The bathtub is coated with several layers of oil, which deeply penetrates the wood structure and protects the bathtub against moisture.
2. Next, a thick covering layer of wax is applied. This exposes the natural characteristics and beauty of wood. The impregnation process takes 10 days.

How are our wooden bathtubs made? Step-by-step process
Each MICHOR bathtub goes through a carefully designed production cycle to ensure stability, durability, and natural beauty. The process begins with the selection of premium hardwoods, followed by long-term seasoning and professional drying. The elements are then layered, pressed, and glued with waterproof adhesives to create a stable structure resistant to shrinkage and expansion. After assembly, the bathtub undergoes multi-stage impregnation with natural oils and waxes, which provide complete water resistance and highlight the wood’s unique grain. The final step is precise finishing and quality control, ensuring that every bathtub meets our high standards.
Machinery and equipment
To achieve the highest precision, we use advanced woodworking machinery combined with traditional craftsmanship. Professional presses ensure stable bonding of wooden layers, while CNC machines provide accuracy in shaping complex elements. Specialized equipment for oiling and waxing guarantees even application of protective coatings. At the same time, many finishing stages are carried out by hand, allowing us to combine modern technology with artisanal attention to detail. This approach ensures that each MICHOR bathtub is both technically flawless and visually unique.
Wooden Bathtub Manufacturing Process Overview
At MICHOR, each wooden bathtub is created through a precise, multi-stage process that combines traditional woodworking with modern engineering. From the careful selection of raw wood to advanced waterproofing and finishing treatments, every step ensures durability, safety, and timeless beauty. Our goal is to craft bathtubs that not only elevate interior design but also provide a long-lasting and relaxing bathing experience.
Wood Selection & Quality Standards
Only the highest-grade hardwoods from Europe, Asia, and Africa are chosen for production. Each piece must meet strict technical and aesthetic criteria, ensuring it is both stable and visually unique. Hardwoods such as ash, oak, and walnut are especially valued for their resistance to changing moisture and temperature conditions, making them ideal for daily use.
Seasoning & Drying Process
To guarantee stability, the wood undergoes natural seasoning in open-air conditions for several years. This is followed by precise mechanical drying, which reduces moisture content and enhances hardness. This dual process ensures that the wood retains its structural integrity and prevents cracking or warping over time.
Structural Stability & Engineering
Every bathtub is engineered from multiple layers of hardwood pressed together using waterproof adhesives. This laminated structure minimizes natural shrinkage and expansion, even under high humidity and varying temperatures. As a result, MICHOR bathtubs maintain their form, functionality, and watertight qualities for decades.
Safety & Certifications
We use certified adhesives and finishes that comply with international safety standards. All materials are tested for durability, water resistance, and safety, ensuring our bathtubs meet the requirements of private households, boutique hotels, and wellness centers worldwide.
Waterproofing & Surface Treatments
To achieve full water resistance, each bathtub is treated with OSMO natural hardwax-oils. This two-stage impregnation process includes deep oil penetration for moisture protection and a final wax coating that enhances durability. The surface remains warm to the touch, resistant to abrasion, and easy to maintain.
Innovations & Craftsmanship
MICHOR combines time-honored carpentry skills with modern innovations. Each bathtub is handmade in Poland by master craftsmen who ensure precision in joinery, finishing, and detailing. Our constant research into better adhesives, coatings, and woodworking techniques allows us to continually refine our products.
Eco-friendly Materials & Sustainability
We prioritize eco-friendly methods and natural preservatives, ensuring our bathtubs are safe for both people and the environment. By using long-lasting hardwoods and sustainable finishing oils, we minimize environmental impact while guaranteeing the durability of each product.
Wood vs Other Materials
Unlike acrylic or stone bathtubs, wooden bathtubs offer natural warmth, unique aesthetics, and a soothing touch. Wood adapts to the body’s temperature, creating a cozy bathing experience that other materials cannot replicate. Moreover, each bathtub is one of a kind, thanks to the natural grain and texture of the wood.
