# Open Bathroom Apartments SIGLA Studio Barcelona Apartment Centers Living Around the Bathroom By Amy Duong | Published 2026-07-31 | Art & Design Source: Trend Hunter, https://www.trendhunter.com/trends/sigla-studio-barcelona References: [martavidal](https://www.martavidal.com/)  The [SIGLA Studio Barcelona](https://www.trendhunter.com/trends/turo-park) apartment rethinks the traditional separation of domestic spaces by organizing its 635-square-foot interior around a compact central core containing the kitchen, bathroom and dressing area. Designed for a client relocating to Barcelona, the layout replaces a series of enclosed rooms with a [continuous living environment](https://www.trendhunter.com/trends/atelierzero) that encourages natural light and ventilation to circulate through framed openings and [reflective surfaces](https://www.trendhunter.com/trends/kier-apartment). The central volume links the private sleeping area with the living space overlooking the façade while maintaining an adaptable floor plan. A freestanding bathtub becomes the apartment's defining feature, occupying an open bathroom connected directly to the living area beneath a large arched opening. A motorized pivoting glass enclosure provides privacy when needed, while the bathroom remains visually integrated into the home during everyday use. Material selections distinguish each function through aluminum-clad plywood in the kitchen, glossy forest-green Cerámica Ferrés tiles in the bathroom and walnut wood in the dressing area, all set within a continuous mineral finish that wraps the floors, walls and ceilings.
