Make one yourself.
Define the onsen type and capacity
Decide between a private home bath, a ryokan guest bath, or a public sento/onsen facility. Determine how many bathers you'll accommodate simultaneously.
Map the purification sequence
Plan the entry, shoe removal area, and the washing zone (kakeyu) before the soaking tub. Include benches, handheld showers, and drainage.
Design the bathing areas
Position the main soaking tub (ofuro) with views if possible. Add secondary features like a cold plunge, sauna, or rotenburo (outdoor bath) per tradition.
Integrate changing rooms and privacy
Add separate male/female changing areas (datsuijo) with lockers, vanity, and clear pathways. Ensure visual screening for outdoor sections.
Refine with materials and ambiance
Use natural materials like hinoki wood, stone, and bamboo. Adjust dimensions, door swings, and window placements for a serene, functional onsen.
