10 Plus-Minus POP Design Ideas for Bathrooms: Creative and Practical Bathroom POP Ceiling Inspiration from My Design Experience

Over the past decade in interior design, I’ve noticed how POP (Plaster of Paris) ceiling designs can transform even the smallest bathrooms into stylish, functional spaces. Minimalist forms are trending, but with bathrooms, I find the ‘plus-minus’ POP concept offers both visual interest and subtle zoning. Small spaces often spark the best creativity, so today I’m sharing 10 plus-minus bathroom POP design inspirations—drawn from real projects and backed by expert insights.

My Take: I used this in a client’s narrow bathroom to elongate the space visually while hiding exhaust ductwork.

Pros: Adds depth, works well with concealed lighting, and fits modern bathroom ceiling design trends reported by Architectural Digest.

Cons: Needs precise measurement—otherwise the layers look uneven.

Tip: Incorporate soft LED strips for a spa-like glow.
