How We Remodel Primary Bathrooms in Older Homes

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: Converting Multiple Small Rooms Into a Primary Suite

Challenge

At first glance, this mid-century home seemed to have plenty of space. A playroom, sunroom, and bedrooms occupied the upper level. The problem was that none of those spaces worked together. The homeowners had square footage, but they didn’t have what they really wanted: a primary suite so they didn’t have to share a hall bathroom with their two sons.

Primary Bathroom Floor Plan Renovations

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

What was once a collection of disconnected spaces became a cohesive primary suite designed for the way the homeowners live today.

Merriam Park Primary Bathroom Remodel: Adding an Ensuite Bathroom Without an Addition

Challenge

One of the biggest misconceptions about primary bathroom remodeling is that adding an ensuite requires an addition. This project proves otherwise. 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: Using Hallway Space to Create a Luxury Primary Suite

Challenge

When people imagine space for a new primary bathroom, they often look at bedrooms first. In this historic Summit Hill home, the opportunity was hiding in plain sight. An oversized hallway occupied a significant portion of the upper level. While it connected rooms, it contributed very little to the homeowners’ day-to-day experience.

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
