The Bathroom and Waste

Vedic tradition is the most explicit about drainage direction — water must exit toward North or East, never toward the sacred NE corner itself.

Traditional Wada architecture's separate toilet structure in the NW is the most complete expression of the waste-separation principle — physical distance, not just directional placement.

Tamil Agama tradition enforces the NE-toilet prohibition more strictly than any other tradition — it is considered the single most important Vastu rule, overriding all other considerations.

Telugu tradition emphasizes the diagonal separation — NE sacred water (Baavi/well) diagonally opposite to NW waste water (toilet) — maximizing the distance between purity and impurity.

Jain Vastu specifies minimum metric distances between toilet and sacred spaces — not just directional separation but measurable physical distance requirements.

Kerala Thachu Shastra specifies minimum physical distance (in traditional measurement units) between toilet and pooja room — the most architecturally precise separation requirement.

Jain Havelis' covered walkway to the NW toilet structure demonstrates the extreme length traditions will go to maintain purity-impurity separation while still providing practical access.

Bengali tradition is the most pragmatically flexible about bathroom placement — accepting non-ideal positions with remedies, reflecting the reality of constrained urban living in Kolkata.

Kalinga temple architecture demonstrates the NE-sacred/NW-waste diagonal at monumental scale — the Amrita Kunda (sacred well) in the NE is diagonally opposite the waste drainage in the NW.

Sikh tradition's concept of Ishnaan (sacred bathing) adds a spiritual dimension to bathroom placement — the NW bathroom is not just a waste zone but a purification space.
