Non-metric multidimensional scaling (NMDS) plot to assess similarities in bacterial community compositions between bath toy biofilms. Filtered OTU sequences, scaled to an even sampling depth, were ordinated with the NMDS method using the Bray–Curtis distance matrix. Triangles represent real bath toy and circles control bath toy biofilm communities. Color codes for real bath toy samples indicate origination from five different Swiss households, while control bath toys are separated into clean and dirty water controls
