【WABURO x Takasho】Total Proposal for 'Japanese Style Spaces' from Garden to Bathroom for Accommodations and Residences. Collaboration Begins for Stone Bathtub 'WABURO'.

Astec Co., Ltd. (Headquarters: Minato-ku, Tokyo, President & CEO: Masaki Uchiyama), a leading Japanese manufacturer of Japanese-style bathtubs and bathrooms, has partnered with Takasho Co., Ltd. (Tokyo Headquarters: Chiyoda-ku, Tokyo, President & CEO: Nobuo Takaoka, TSE Standard: 7590), a garden lifestyle manufacturer. Through this collaboration, Astec's flagship stone bathtub 'WABURO' will be offered within Takasho's product lineup. This partnership will enable the proposal of 'high-quality Japanese-style total spaces' that seamlessly connect gardens and bathrooms by combining exterior materials with authentic stone bathtubs.

Bathtub: Stone Type 1711 Size + Water Outlet Deck Material: EverEco® Wood Real 115 Width Olive

Background of Collaboration

In recent years, there has been a surge in design needs for luxury resort facilities, ryokans, and high-end residences aiming to capture inbound demand, by integrating indoor spaces with outdoor terraces and gardens. Particularly, spaces like open-air or semi-open-air baths, where one can soak while enjoying a view of a beautiful garden, have become indispensable elements for providing guests with supreme relaxation, contributing to their physical and mental well-being and happiness.

However, when designing the overall facility, exterior (landscaping) and bathing facilities were separate categories of products, requiring separate ordering and coordination. By collaborating, Takasho, which advocates for 'creating comfortable spaces and towns,' and Astec, which excels in creating bathing spaces with a 'Japanese' aesthetic, have established a system to smoothly plan and propose heavy natural stone-clad bathtubs as 'one total space' alongside Takasho's diverse garden materials to architectural firms and facility developers.

◆ New Value Provided by This Initiative and Strengths of 'WABURO'

1. Total Proposal Eliminating the Boundary Between 'Garden' and 'Bath'

By combining Takasho's various exterior products (louvers, lighting, planting, etc.) with Astec's Japanese-design bathtub 'WABURO,' it becomes easier to design and propose authentic Japanese-style bathing spaces without compromise, transcending the boundaries of different product streams.

2. Elimination of Water Leakage Risk and Reliable Hot Spring Compatibility

The structure, which involves applying natural stone to the interior of an FRP base, eliminates the risk of water leakage. It boasts excellent durability and waterproofing, and its resistance to the effects of hot spring components ensures safe use even in accommodation facilities.

3. Reduced Construction Time and Stable Quality

As a standardized stone-clad bathtub (available in 5 selectable sizes) manufactured in a factory, on-site construction time is significantly reduced. This allows for stable quality and smooth installation, even for accommodation facility projects involving multiple rooms.
