Tesis ini bertujuan untuk mengeksplor bagaimana toilet dapat mempengaruhi pengambilan keputusan dalam konteks wisata alam nature based tourism di Indonesia. Berbagai penelitian menyatakan pentingnya fasilitas sebagai faktor yang dipertimbangkan dalam pariwisata, namun belum banyak yang secara khusus membahas toilet sebagai bagian dari fasilitas tersebut dari perspektif wisatawan serta bagaimana pengaruhnya terhadap perilaku wisatawan. Metode kualitatif digunakan dalam penelitian ini melalui FGD dan wawancara, serta dilakukan juga observasi dalam pemilihan sampel penelitian. Penelitian ini menunjukkan bahwa dari berbagai faktor, usia wisatawan dan ekspektasi terhadap destinasi wisata menjadi faktor terpenting dalam menentukan pentingnya toilet di destinasi wisata alam. Kemudian, pengalaman buruk terhadap toilet, terutama yang menyebabkan penyakit, dapat menjadi trauma yang berpengaruh signifikan terhadap keputusan untuk mengunjungi ulang dan merekomendasikan suatu destinasi wisata. Secara keseluruhan, toilet memiliki peranan penting dalam mempengaruhi perilaku dan pengambilan keputusan wisatawan dalam konteks wisata alam, khususnya bagi wisatawan yang mementingkan segi kenyamanan dan kesehatan.
