Architect Julia Gallagher redesigned a 40-square-foot powder room for her cousin, Amma Phaff, combining colorful wallpaper on the walls and ceiling with burgundy floor tile and a corner mirror. The project also moved the toilet and replaced a vanity with a wall-mounted sink to improve the room’s layout. Gallagher said the mirror and wallpaper made the small room feel larger; the report provides no cost or independent measurement of that effect.

Architect Julia Gallagher redesigned a 40-square-foot powder room for her cousin, Amma Phaff, using bold patterned wallpaper, a corner mirror and a revised layout intended to make the small room more functional and feel more spacious, much like the ideas in ways to make a small bathroom feel bigger. Apartment Therapy’s before-and-after report says the work also addressed a practical problem: the toilet’s position had prevented the bathroom door from opening fully.

Gallagher, principal architect and founder of JAGA Studio, selected a “mood ring” wallpaper for both the walls and ceiling. She described its look as resembling a cross-section of bubblegum. The report says the wallpaper was paired with matte ceramic floor tiles in warm burgundy, with grout in a matching color.

The layout changes included moving the toilet to allow the door to open and replacing the original vanity with a wall-mounted porcelain sink. The report describes the previous toilet as speckled stainless steel and says it was replaced with a porcelain model. It does not provide product details or explain the plumbing work involved.

A custom-cut corner mirror was another central part of the design. Gallagher told Apartment Therapy that finding someone able to cut the mirror proved difficult. She said its placement, combined with the wallpaper, changed how the room felt. The article does not include measurements comparing the room’s apparent size before and after.

The developmentApartment Therapy published a before-and-after report on architect Julia Gallagher’s colorful redesign of her cousin’s 40-square-foot powder room.

A Small Room Gets a New Layout

The project shows how a small-room redesign can combine layout changes with decorative choices. Moving the toilet addressed the door clearance, while removing the vanity made room for a wall-mounted sink. Those are functional changes; the wallpaper, tile and mirror supplied the visual identity Gallagher and Phaff wanted.

For readers considering a similar update, the report’s distinction between these roles matters: a mirror and bold pattern can affect the perception of space, but they do not add floor area. The article presents the room feeling larger as Gallagher’s assessment, not as a measured result or a universal guarantee. It also lists the project cost as not available, leaving readers without a budget benchmark.

Design Choices Behind the Powder Room

The bathroom belongs to Phaff, Gallagher’s cousin and client. Gallagher told Apartment Therapy that the cousins grew up influenced by their grandmother’s fearless use of color. According to the report, Phaff wanted her home to reflect that creative energy, and the cousins agreed early on that the powder room should use colorful wallpaper and a corner mirror.

The supplied report identifies the project as a residential before-and-after but does not give its completion date, location, construction schedule or detailed scope. It says the design addressed both a cramped layout and a room Gallagher characterized as beige and unattractive. The documented changes are specific to this bathroom; the source does not claim that the same arrangement would work in every small room.

““A corner mirror detail paired with the psychedelic wallpaper amplifies the space into another dimension, turning the room into a joyful little jewel box hidden inside the home.””

— Julia Gallagher, principal architect and founder of JAGA Studio, speaking to Apartment Therapy

Costs and Construction Details Remain Unreported

Apartment Therapy lists the project cost as not available. The report also does not state when the renovation took place, how long it lasted, where the home is located, or whether the toilet move required broader plumbing changes. It gives no dimensions for the mirror, sink or clearances.

The claim that the room feels bigger comes from Gallagher’s account of the design, including her description of the corner mirror’s effect. No independent assessment, before-and-after measurements or photography-based analysis is included in the supplied text. The report also does not establish whether the wallpaper or other materials are suitable for every bathroom environment.

No Further Project Update Listed

The supplied Apartment Therapy report does not announce another renovation phase or a follow-up milestone. It presents the bathroom as a completed before-and-after project, with no additional work or future plans stated for the room.

Readers seeking practical details beyond the design description would need information not included in the report, such as the project budget, product specifications and installation requirements. The available account confirms the main design choices and layout changes, but it does not provide enough information to estimate the cost of reproducing them.
