Material check: wood, plastic, or EPP? The big toilet stool comparison.

A toilet stool is not an ordinary piece of furniture. It stands in the bathroom—a room with high humidity, temperature fluctuations, and strict hygiene requirements. Whether after showering, with the heating on in winter, or in direct contact with cleaning products: the material determines how long the stool will last, how it feels, and how sustainable it is. Wood, plastic, or EPP? We compare the three most common materials and show what really matters.

First, the conclusion

• Wood: Natural and warm, but heavy, high-maintenance, and sensitive to moisture - including the risk of swelling and mold.
• Plastic (polypropylene/PP): Inexpensive and easy to clean, but often cold to the touch and with a poor environmental footprint.
• EPP (expanded polypropylene): Robust, extremely lightweight, 100% recyclable, moisture-resistant.

Why the choice of material is crucial for bathroom products

Bathrooms and toilets are wet rooms - and therefore a challenge for any material. A toilet stool must withstand fluctuating conditions on a daily basis:

Moisture and steam: After showering or bathing, the humidity rises to over 80%. Materials that absorb water swell, warp, or provide a breeding ground for mold.

Cleaning agents: Hygiene is paramount in the bathroom. The material must be resistant to disinfectants, toilet cleaners, and other chemicals.

Temperature changes: From cool underfloor heating to warm room air – the material must not deform or become brittle.

Odor development: Porous surfaces can absorb moisture and bacteria, which leads to unpleasant odors in the long term.

A toilet stool is therefore not just a functional aid – it must be robust, hygienic, and durable. The choice of material is crucial.

Material A: Wooden toilet stool – aesthetics meets care

Wood is timeless, natural, and warm – no wonder many manufacturers (and their customers) rely on this material. But in the bathroom, wood quickly reveals its weaknesses.

Advantages:

• Natural look: Wood has a high-quality appearance and blends in with many interior styles.
• Warm feel: Unlike cold plastic, wood feels pleasant to the touch – at least initially.
  

Disadvantages:

• Hygiene trap: Wood is naturally porous. Even when sealed, moisture can penetrate through cracks or joints. This creates ideal conditions for germs, bacteria, and mold.
  
• High maintenance: Regular oiling or varnishing is necessary to prevent cracks, discoloration, and warping. Neglecting this risks material fatigue.
  
• Sensitive to moisture: If the stool is kept in the bathroom permanently, the wood may swell or warp. This is particularly problematic when combined with other materials such as metal hinges.
  
• Weight: Wooden stools are often heavy and unwieldy—not ideal if you want to move or store them regularly. 

Conclusion: Wood is visually appealing, but in a damp bathroom it is a high-maintenance solution with hygiene risks. Due to its heavy weight, it is also difficult and unpleasant to maneuver.

Material B: Cost-effective plastic – The functional standard

Most toilet stools on the market are made of hard plastic such as polypropylene (PP) or ABS. They are functional, inexpensive – and have clear weaknesses.

Advantages:

• Easy to clean: Hard plastic is washable and resistant to most cleaning agents.
  
• Inexpensive: Simple plastic stools are cheap to manufacture and therefore available in stores for little money.
  
• Moisture-resistant: Unlike wood, hard plastic does not absorb water.

Disadvantages:

• Cold to the touch: Plastic feels unpleasantly cold – especially in winter or on tiles. This significantly reduces comfort.
  
• Poor environmental performance: Many plastic stools are made of plastic that is difficult or impossible to recycle. They are usually produced in the Far East, involving long transport routes and high CO₂ emissions.
  
• Cheap appearance: Hard plastic often looks inferior and does not fit in with high-quality bathroom furnishings.
  
• Stability: Under heavy loads, cheap plastic can creak, deform, or break.

Conclusion: Plastic is pragmatic, but neither sustainable nor high-quality in appearance.

Material C: EPP (expanded polypropylene) – the smart & sustainable solution

EPP is a high-tech material that originally comes from the automotive and aviation industries. Due to its unique properties, such as low weight, dimensional stability, resilience, shock absorption, and insulation, it is used in a variety of ways in these industries. However, it is now also conquering the lifestyle sector—and for good reason.

What is EPP?

EPP stands for expanded polypropylene - a thermoplastic material that consists of over 90% air. Its closed cell structure makes it impermeable to water. It is also extremely lightweight, robust, and skin-friendly. The material is used in well-known and popular consumer products such as the Blackroll fascia roller and the Stapelstein children's toy.

Advantages of EPP:

• Moisture-resistant: Thanks to its closed cell structure, EPP does not absorb water – no mold, no odors, no germ formation.
• Extremely lightweight: Over 90% air content makes EPP featherlight. The stool can be moved or stored away effortlessly.
• Pleasant feel: Unlike hard plastic, EPP feels much warmer and more pleasant – it adapts to the room temperature.
• 100% recyclable: EPP is a monomaterial and can be completely returned to the raw material cycle. The recycled content is already up to 25%. The Ocean version of our stuul even consists partly of recycled fishing nets.
• Durable and robust: EPP is virtually unbreakable, dimensionally stable, and can withstand impacts without damage.
• Made in Germany: Production takes place in Saxony using climate-neutral electricity and closed water cycles – short delivery routes, transparent processes, high quality standards.
• Easy to clean: EPP is resistant to most chemicals and can be easily cleaned with water, soap, or disinfectant—it can even be sterilized.
  

Conclusion: EPP combines the hygienic advantages of plastic with a warm feel and offers an excellent ecological balance. A modern, well-thought- out solution for health-conscious people.

The big material comparison

Focus on hygiene: How the cell structure prevents germ formation

One crucial point that is often overlooked is the cell structure of the material.

Wood has open pores – even when sealed, moisture can penetrate through cracks, cut edges, or joints. This creates ideal conditions for bacteria and mold.

With EPP, the situation is completely different: the closed cell structure means that no moisture can penetrate the material. There are no breeding grounds for germs. The material remains hygienically clean – even with daily use in a damp bathroom.

This makes EPP particularly suitable for environments with high hygiene requirements – such as hotels, clinics, or households with immunocompromised individuals.  Or simply in your bathroom ;-)

Conclusion & recommendation

The decision between wood, plastic, and EPP is a compromise between price, appearance, and functionality. But with EPP, there is a solution that meets all three requirements at the highest level:

✅ As hygienic as plastic – but without the cold feel 
✅ Warm and pleasant like wood – but without the maintenance 
✅ Sustainable thanks to 100% recyclability and Made in Germany production 
✅ Durable and robust – a product for life

If you value health, design, and sustainability, EPP is the material of the future. No compromise – just a conscious decision for quality.

See for yourself the feel and quality of “Made in Germany.” Because health starts with the right materials – right in your bathroom.
