Illya's bedroom contains a door to an excessively large, ornate bathroom - one might think you could just host a party inside, if that wouldn't be a kind of weird place to have a party. Past the finely upholstered and wide lounging couch at the room's entrance is a bath is set into the marble floor, with a staircase leading a few steps down into it. Lighting is provided by shelving and floor-level wall crevices lined with always-burning white wax candles, and for some reason the large spigots which provide water to the baths also provide red rose petals to float atop it.

A two-person bath sits at the far end complete with privacy curtain - next to it is a sink and mirror. The pattern on the sink seems to change periodically - the flowers painted on it which entwine its rim represent the flowers of each current member of LiliS, and mingled in with them are softly luminescent birds. The mirror is gold-rimmed, its frame wrapped with snowdrop flowers. Also nearby is a set of golden ring hangers for towels, and a set of cabinets, and a snowdrop-patterned bidet toilet.

Finally, against the wall closest to the main bath is a long horizontal mirror with an attached granite counter at its bottom - floral shampoos, soaps, and conditioners are stored here, and there are brushes and scrubbers as well. A set of stools allows for sitting to use the wash basins sitting upon the counter.
