Before and After: Modern Bathroom Makeover Through Smart Space Planning

Transforming a cramped, outdated bathroom into a spacious and stylish retreat is one of the most rewarding home improvement projects a homeowner can undertake. When designer Cillesa Ullman tackled the tiny guest-room bath in her 1960s post-and-beam home in Oakland, California, she proved that dramatic results are possible even with challenging constraints. By annexing adjacent spaces, relocating the entry, and thoughtfully upgrading every fixture and finish, she turned a bare-bones en suite into a shared bath that serves an entire floor with elegance and ease. The principles behind this transformation apply broadly to anyone looking to rethink their own bathroom layout. For more inspiration on blending traditional homes with contemporary upgrades, take a look at this Modern Craftsman Mountains Mountain Modern Architecture Design Asheville approach, which similarly balances respect for original character with a fresh, updated vision.

Expanding the Footprint by Reclaiming Adjacent Spaces

The original guest-room bath was a classic example of 1970s builder-grade design: cramped, dated, and accessible only through the bedroom. The room measured just enough to squeeze in a shower stall, toilet, and small vanity, with no room to move. Ullman knew that the only way to achieve the spacious bath she envisioned was to steal square footage from the surrounding floor plan.

The solution involved two key moves. First, she relocated a nearby laundry room, reclaiming its footprint for the bathroom. Second, she reconfigured a double-width bedroom closet, taking back space that had been allocated to storage. These two adjustments freed up enough room to create an 80-square-foot bath with three distinct zones: a double vanity area, a toilet alcove, and a combined tub and shower space. Homeowners considering similar expansions can find practical budgeting and design advice in this Renew Redo Bath Makeover Before After feature, which covers cost-conscious approaches to full bathroom renovations.

• Relocating the laundry room freed approximately 16 square feet for the new bathroom footprint
• Reclaiming part of the bedroom closet added another 10 square feet of usable space
• Closing off the original bedroom door and creating a hallway entrance made the bath accessible to the entire floor rather than just one bedroom
• Annexing adjacent spaces eliminated the closed-off feeling of the original en suite layout

The lesson is clear: before tearing out fixtures, look at the rooms around your bathroom. A laundry room, a linen closet, a hallway, or an oversized bedroom closet can often yield the extra square footage needed for a much more functional layout. Even small gains of 5 to 10 square feet can make the difference between a tight bath and one that truly works for multiple users.

Reconfiguring the Floor Plan for Shared Access

One of the most impactful changes Ullman made was relocating the bathroom entry. In the original layout, the only way to reach the bath was through the guest bedroom. This made the bathroom feel private but also limited its usefulness. After the renovation, the door opens onto a hallway, allowing the bath to serve a second bedroom that was created in the lower level renovation.

This kind of floor plan rethink is a powerful tool in older homes where original layouts no longer match modern living patterns. The approach echoes the thinking behind An American Bungalow Before And After A Complete Craftsman Home Renovation Guide, where thoughtful reconfiguration of interior space unlocks far more functionality than a simple cosmetic refresh could achieve. In both cases, the floor plan changes were the foundation upon which every other improvement rested.

The floor plan update also included a smart zoning trick: a partial partition wall at the end of the double vanity creates a visual and spatial separation for the toilet alcove. This allows two people to use the bathroom at the same time with more privacy. Meanwhile, the tub sits against the exterior wall beneath a new 42-by-32-inch awning window, which provides light, ventilation, and privacy thanks to its acid-etched glass finish.

Selecting a Cohesive Material Palette

Ullman found her color inspiration when she came across a penny tile glazed in varying shades of aqua, which reminded her of the iridescent colors of a mermaid tail. This playful yet elegant choice became the thread that ties the entire bathroom together. The penny rounds cover the tub skirt, line the shower floor, and make a repeat appearance on the back of the double vanity. The soft blues create a splash of personality against the cool gray walls, painted in Benjamin Moore Whitestone.

The material selections offer valuable lessons for anyone planning a bathroom renovation. The combination of large-format tiles on the floor, subway tiles on the walls, and small mosaic tiles on accent surfaces creates visual variety without chaos. The same principle applies when rethinking period homes: Reversing The Floor Plan Creating A Modern Bath With Period Charm In Your American Foursquare demonstrates how respecting a home’s original character while introducing contemporary materials can produce a space that feels both timeless and up to date.

Here are the key materials used in this makeover and why they work well together:

• Aqua penny-round porcelain tiles on the tub apron, shower floor, and vanity back splash. Their small format makes them naturally slip-resistant on wet surfaces.
• White 5-by-15-inch rectangular tiles on the shower walls, oriented vertically to make the ceiling feel higher. This vertical orientation is a simple trick Ullman recommends for any small bathroom.
• Oyster-gray large-format porcelain tiles on the main bathroom floor. The large tiles reduce grout lines, making the floor feel cleaner and more expansive.
• Bianco Supremo quartz countertops on the vanity, shower bench, and niche shelf. Quartz offers low maintenance and consistent appearance across all horizontal surfaces.
• Brushed-metal edge profiles (Schluter strips) border the shower niche, adding a crisp, contemporary detail that frames the accent tile inside.

The expert advice from Ullman is worth highlighting: orienting rectangular wall tiles vertically draws the eye upward and emphasizes the height of the space, creating a visual lift. It is a subtle twist on a classic installation pattern that gives the room a fresh, modern aesthetic without requiring any additional materials or expense.

Fixtures, Storage, and Finishing Details

A successful bathroom renovation depends as much on smart storage and fixture selection as it does on the big-picture layout. Ullman made several choices that maximize function without sacrificing style.

The double vanity spans 72 inches across the wall and features rectangular undermount sinks by Kohler paired with streamlined single-handle faucets from Hansgrohe. On each end of the vanity, pull-out shelf towers provide vertical storage for towels, toiletries, and linens. This is a particularly clever solution for a guest bath, where multiple visitors need accessible storage without cluttering the countertops.

The walk-in shower measures 36 by 39 inches and includes a built-in bench seat and a toiletry niche. The niche is bordered with a brushed-metal edge profile and accented with the same blue penny rounds used on the shower floor and tub apron. A height-adjustable shower wand mounted on a vertical bar accommodates users of different heights, making the shower practical for guests of all ages.

1. A Toto toilet in a dedicated alcove behind the partition wall for privacy
2. Recessed medicine cabinet from Robern for hidden storage above the vanity
3. Two 30-inch towel bars flanking the shower, one on each side, for easy guest access
4. Wall-mounted sconces from Modern Forms with a brushed-nickel finish and acrylic shades that provide soft, dimmable light
5. An apron-front jetted tub from Americh centered on the exterior wall beneath the awning window, with a wall-mounted faucet for easy reach

Radiant heated floors were installed beneath the large-format porcelain tiles, adding a touch of luxury that is especially welcome in a lower-level space. The heated floor not only makes the room more comfortable but also helps dry the floor quickly after showers, reducing moisture and maintenance.

Key Lessons for Your Own Bathroom Renovation

Ullman did most of the demolition work herself, which gave her firsthand knowledge of what lay behind the walls and helped her make informed decisions about the new layout. While not every homeowner needs to pick up a sledgehammer, being involved in the early stages of a renovation helps you understand the space more deeply and can reveal opportunities that might otherwise go unnoticed.

The entire project demonstrates that the most successful bathroom renovations are those that balance three priorities: smart space planning, cohesive material selection, and thoughtful fixture placement. By annexing the laundry room and part of a closet, moving the entrance to serve the whole floor, and choosing durable materials with a consistent aesthetic, Ullman created a bathroom that feels both luxurious and practical. The space now serves a variety of guests with ease, from the heated floors that warm bare feet to the adjustable shower wand that accommodates different heights.

For readers planning their own renovations, the broader lessons from this and similar projects are captured in Lessons From Before And After Home Transformations, which examines how thoughtful renovation choices create lasting value. Whether you are expanding a tiny en suite into a shared family bath or simply refreshing finishes, the principles remain the same: look for hidden square footage in adjacent rooms, invest in materials that will hold up to daily use, and choose fixtures and finishes that bring you joy every time you walk through the door. Ullman described her finished bath as both elegant and whimsical. That combination of sophistication and personality is the ultimate goal of any successful home renovation.
