One of the most common questions homeowners ask is:
“How do you add a primary bathroom to an older home that wasn’t designed for one?”
At Quartersawn, we specialize in remodeling older homes throughout Minneapolis, St. Paul, and the Twin Cities. Many historic and early-20th-century homes were built long before primary suites, walk-in closets, and ensuite bathrooms became standard. Through thoughtful space planning and design-build expertise, we help homeowners create luxury primary bathrooms while preserving the character that makes older homes unique.
Whether we’re converting unused rooms, reconfiguring bedrooms, or redesigning entire upper levels, our goal is always the same: create a functional, private retreat that feels like it has always belonged in the home.
What’s the Best Way to Add a Primary Bathroom to an Older Home?
The answer depends on the home’s existing layout, but the most successful projects typically involve:
- Reconfiguring underutilized spaces
- Combining neighboring rooms
- Improving traffic flow and privacy
- Creating walk-in closets and storage solutions
- Preserving original architectural details
- Adding luxury features such as walk-in showers, soaking tubs, and double vanities
The following projects showcase how strategic design can transform older Twin Cities homes into modern primary suites.
Moody Mid-Century: Creating a Luxury Primary Suite Through Space Reconfiguration
Challenge
The upper level of this mid-century home consisted of several disconnected rooms, including a playroom, sunroom, and primary bedroom. Multiple doorways and awkward circulation patterns created a fragmented floor plan that lacked privacy and functionality.
Solution
Rather than adding square footage, we completely reimagined the existing layout.
- The former playroom became a custom walk-in closet.
- The sunroom was transformed into a light-filled primary bedroom.
- The original bedroom was converted into a spa-inspired primary bathroom.
The result is a cohesive primary suite that maximizes natural light, improves flow, and supports modern living while respecting the home’s original architecture.
Features
- Custom walk-in closet
- Luxury primary bathroom
- Improved upper-level floor plan
- Enhanced privacy
- Preserved mid-century character
Merriam Park Primary Bathroom Remodel: Adding an Ensuite Without an Addition
Challenge
Like many early-1900s homes in St. Paul, this Merriam Park residence had only one shared bathroom on the second floor. The homeowners wanted a private primary suite but hoped to avoid building an addition.
Solution
We reconfigured the existing floor plan by combining two adjacent bedrooms.
This allowed us to create:
- A spacious primary bedroom
- A walk-in closet with custom storage
- A new ensuite bathroom
By working within the existing footprint, we delivered a dramatic transformation without increasing the home’s square footage.
Features
- Double vanity
- Walk-in shower
- Custom tilework
- Dedicated primary suite
- Optimized storage solutions
This project demonstrates how strategic remodeling can dramatically improve functionality while maintaining the home’s original footprint.
Summit Hill Haven: A Historic Home Primary Bathroom Remodel
Challenge
This historic Summit Hill home featured an oversized hallway that occupied valuable square footage but contributed little to daily living.
Solution
Through careful space planning, we transformed this underused area into a luxurious primary suite while preserving the home’s historic character.
The new design includes:
- A freestanding soaking tub
- A steam shower
- A private water closet
- A walk-in closet
- A built-in home office nook
The result is a highly functional suite that blends timeless architecture with modern amenities.
Features
- Historic home renovation
- Luxury soaking tub
- Steam shower
- Walk-in closet
- Home office integration

A successful remodel requires balancing modern functionality with respect for the home’s original design.
At Quartersawn, we specialize in finding creative solutions that improve how homeowners live while preserving the character they love.
