When the hotelier couple Ulli and Christian Mittermeier converted a former entrepreneur's villa from the Gründerzeit in Rothenburg into a hotel, they wanted to combine the quality of a high-end design hotel with the freedom and informality of a private apartment. While the colour concept of the exterior of the house is characterised by black, transparency and openness dominate inside. The leading idea of the design: consciously omit details, and then make sure everything else is of the very highest quality. "We asked ourselves what the first thing is that a hotel guests looks at, and quickly realised it was the bathroom," explains Christian Mittermeier. The bathroom signals the standard of the hotel to the guest, and is often a source of inspiration. Therefore the hoteliers opted for generous, floor-level showers with plenty of space. The matt black of the BetteFloor shower area is a perfect match both structurally and in colour for the black of the bathroom tiles, and merges seamlessly with the tile structure.
