Henning Senger is an important partner to TOTO, a Japanese company specialised in high-end bathroom solutions. Senger considers one TOTO WASHLET to be a state-of-the-art addition to his extraordinary container toilets. “The advantages they offer in terms of cleanliness and hygiene meet the high standards of guests who spend their time in the exclusive Champions Circle area,” explains the experienced sanitary specialist. For many guests, intimate warm water cleansing is an entirely new experience. Others are familiar with WASHLET from their stays in elevated five-star hotels around the world. Using WASHLET is especially comfortable at major events during warm summer temperatures – and Senger believes that it should always be part of his VIP containers. Henning Senger knows first-hand: “TOTO stands for high-end ceramics that retain their brilliance even after intensive use over many years. They look as clean and new as on the first day.”

After the CHIO in Aachen, the containers featuring TOTO WASHLET will continue on for use at premium automobile manufacturers, exclusive sports and corporate events, as well as weddings. “We want guests to be surprised and delighted when they go to the toilet. Our containers are more than just clean and functional – they convey a sense of style, comfort and appreciation,” continues Senger.

Henning Senger is a member of bad & heizung concept AG, a German association of high-end bathroom construction companies that specialise in heating as well as bathroom design and renovation.

How did you come up with the idea to design and rent exclusive container toilets?
Henning Senger: We had this crazy idea while we were at a wedding. The bride and groom had an amazing tent, great food, music and performances – everything your heart could desire. But the portable toilets just weren’t right for this event. We thought that we could make a better solution and started working on it the following Monday. First, we bought a trailer and converted it into a high-end toilet. In the meantime, we’ve switched from trailers to containers. But this is how we started 15 years ago – with enthusiasm and a passion to create something new.

What is your approach?
Henning Senger: Our goal is to offer portable toilet solutions that are more than just functional. We design high-end container toilets that blend seamlessly into every sophisticated event – in terms of their look, technology and service. An especially important aspect of our business is that our toilets be more than just clean and functional – they convey a sense of style, comfort and appreciation. This requires modern equipment, high-quality materials, carefully considered room layouts, lighting, mirrors, and often small extras like music or fragrance systems.

What do your customers appreciate about your containers?
Henning Senger: Our customers appreciate the combination of quality, design and comfort. Our list of references ranges from prominent automobile manufacturers to premium industry partners and event agencies who want to make every aspect of their visitors’ experience exclusive and elevated. In addition to being functional, our containers need to impress – after all, the quality is in the details. Usually, it’s a positive surprise for every guest!
